  4. (Thank you so much, Rab D, for the following information. This info has been authorized by BBV as accurate and perfectly fine to share on ECF!)

    Alas, new problem: the seal on my 2/3 month old Boro is loose. It seems to have stretched, and is difficult to get in place and stay where it should. Has anybody else encountered this / found a fix?

    Alas, I'm not musical like spacelord, so no guitar pick - made do with the pink plastic filling needle which came with the BB. I contacted BBV, and received reply below with permission to post it here on ECF - may interest other Boro users, sooner or later!

    "Hi there! Sounds like a dry gasket issue. I'm including some gasket changing instructions (you won't need a new gasket but follow all the other steps)
    1) Disassemble the tank and take the old gasket out, rinse out the tank (clean it well), make sure the track where the gasket sits is nice and clean
    2) take the new gasket and with a microfiber cloth and a little denatured alcohol wipe the gasket and make sure it’s very, very clean (no hair or little debris fragments)
    3) lay the gasket into the track and use a toothpick to push it into the track (don’t poke it in, be very careful), specifically around the five nubs on the gasket.
    4) Now that the gasket is in place, make sure it’s perfectly flat and it’s not bulged up anywhere. Then take the glass piece and make sure that as well is very clean. Then take some e-juice and put it over the entire gasket, spread it around to make sure the gasket is covered. That will allow the glass to easily slide into place.
    5) When you slide the glass into place make sure the tab on the bottom of the glass face is on the right side. Very slowly start pushing the glass into the groove if the tank. Don’t force it. Once it’s all the way up pull it down again about 1/4 of the way and push it back up - do that a couple of times to make sure the gasket is seeded well.
    6) Visually check that there are no weird air pockets or spots where the gasket isn’t touching the glass.
    The key is cleanliness and putting e-juice on the gasket!!"
  5. Here is some very useful and timely battery info, provided by one THE most outstanding ECF'ers, alden. :)


    SONY VTC5 batteries have been somewhat the gold standard for vapers but they're hard to find, expensive when you find them and have a high likelihood of being counterfeited.

    I highly recommend Samsung's 25R batteries. LG's HE2 or HE4 batteries are also good choices.

    Very trusted supplier at great prices. $6 for a single 25R. They also have SONY's VTC4 & 5

  10. The Billet Box FAQ:
    By Vapian, Version 1.3, May 2014
    Graciously reviewed/edited by Drunk_J & Katdarling


    Routine maintenance of the Billet Box is recommended as follows:

    Every week or two, or any time the sliding door requires more forced to open or begins to sound or feel as if it is grinding:
    - Remove the door.
    - Use a paper towel, toothpick and/or cotton swab to clean the side rails on the door, the slots that the door slides into, and the locking ball track on the door. Remove any residue from liquids, oxidation or normal wear.
    - Attempt to push and/or spin the door locking ball, also removing any residue.
    - Use a clean bit of paper towel and a toothpick, or a cotton swab, to apply a few drops of either olive oil (recommended by Billet Box Vapor) or very light coat of teflon fishing reel grease (recommended by some users) to the door rails and slots, the ball track in the door, and the door locking ball.
    - Use another clean bit of material to remove any excess lubricant.

    The threaded hole for the Brass Ring can be cleaned by inserting a small portion of rolled-up paper towel, pushing it against the threads and running this around the threads.

    Regular cleaning should keep electrical connections working properly. However, non-toxic anti-oxidants such as DeOxIt can be applied to electrical connections such as the threaded hole for the Brass Ring and the positive atomizer connection inside the tank area. This can help ensure positive connections and prevent reduced performance due increased resistance caused by oxidation.


    Q. Does the Billet Box come with any spare parts?
    A. Yes.
    Your Billet Box should come with a baggie containing spare O-rings for the tank and spare silicon gaskets for the cartomizer positive pin at the bottom of the tank compartment.

    Q. Does Billet Box have a rebuildable atomizer tank?
    A. A rebuildable atomizer tank design is being considered but is not yet in production (as of May 2014).
    Though not all are Billet-Box specific, other options as mentioned under ATOMIZERS/CARTOMIZERS above are available.

    Q. The carbon-fiber panels are cool, but are there other options (wood, leather, rubberized, etc.)?
    A. As of May 2014, carbon-fiber panels are the only production option. Some one-off Billet Boxes have been made with alternate materials, but none have been made available for sale (as of May 2014).
    It is highly likely that other materials will be more readily available in the future.

    Q. When should I replace the tank O-rings or silicon gasket for the cartomizer positive pin?
    A. The O-rings or gasket should last quite a while under normal use, but should be replaced whenever they are obviously nicked or damaged.
    Even if damage is not obvious, replacement may be indicated if:
    O-rings: Liquid drips or drains from top or bottom of the tank, or the cartomizer slides in or out too easily.
    Silicon gasket: Excessive liquid "condensation" is consistently found behind, under or on top of the tank.

    Q. What is the size of the black o-rings that fit into the tank?
    A. (As stated in Part 1 of this Blog) The tank o-ring = 1.5mm thickness x 9mm ID (12mm OD).
    (The red silicone ring is something made in the Billet Box Vapor shop. It's a .062" x .3", ".032" thick" flat silicon washer.)

    Q. How do I replace the silicon gasket at the cartomizer positive pin connection?
    A. The gasket is seated in a channel milled around the positive pin.
    Use a toothpick to pry under the outer edge until the gasket begins to pop out, then circle around if necessary to completely remove it.
    Replace the gasket by placing it over the positive pin and into the channel.
    Use your finger or a toothpick to gently but fully seat the gasket into the channel until it is flush with the bottom of the tank compartment.

    Q. Katdarling said there would be cake!
    A. Don't listen to her.
    The cake is a lie.
    (But there might be pie.)

    By Vapian, Version 1.3, May 2014
    Graciously reviewed/edited by Drunk_J & Katdarling


    Q. Can I use my own drip tips on the Billet Box?
    A. Yes.
    Most standard 510 drip tips should fit inside the brass ring.
    If the tip is slightly too small, it can be made to fit with larger replacement O-ring or by removing the O-ring, wrapping a bit of unflavored dental floss around the O-ring slot, and replacing the o-ring.
    If the tip is slightly too large, it might be made to fit by sanding down the diameter. Do this at your own risk.

    Q. What should I use to back out or tighten the brass ring?
    A. A standard U.S. quarter or nickel coin is ideal. These will fit right into the slots on the brass ring and provide more than enough leverage.

    Q. What if I don't have the required coinage?
    A. Some folks have found that their drip tip fits in tightly enough to loosen or tighten the brass ring with no coin required.
    It is possible to use the door of the Billet Box itself, but this is NOT RECOMMENDED as it could deform the door making it EXTREMELY difficult to install or remove later.

    Q. How much should I tighten the brass ring?
    A. The brass ring should be tightened down just enough to make contact with the cartomizer body.
    Too loose, and the cartomizer will not fire.
    Too tight, and the cartomizer might damage the silicon gasket around the cartomizer positive pin.

    It is worth noting that there have been two production Brass Rings.
    The first version simply "sat" on top of the cartomizer establishing the ground path. Later testing indicated in some cases this may have led to liquid condensation inside the Billet Box tank compartment.
    The second version has a small extension that fits inside the cartomizer with a O-ring to provide a seal. This greatly reduces incidents of condensation in the tank compartment.


    Q. What kind of batteries does The Billet Box use?
    A. The Billet Box is designed to use 3.7 volt, AW ICR 123 / 16340 (Black w/silver label), protected, button-top batteries.
    The use of unprotected batteries of any kind is NOT recommended.

    Q. How long do those batteries last in the Billet Box?
    A. Short answer: until they die.
    Long answer: Most users report anywhere from 1/2 to a full day of vaping with a freshly charged pair of batteries and a 3.0 ohm cartomizer. Depending on your atomizer or cartomizer resistance and how you vape, YMMV.

    Q. How do the batteries die - do they peter out, cut off, or...?
    A. The Black AW ICR 123's tend to keep their output and performance constant almost to the very end with only the last two or three vapes being weak.

    Q. Can I use other brands or types of battery?
    A. The Billet Box battery compartment is very specifically designed for the physical size of the AW ICR 123 / 16340 batteries and has very tight tolerances.
    But, any 16340 or 123-type battery that is button top, no longer than 34.2 mm or larger than 16.6 mm in diameter should fit.
    If you MUST buy a different brand/model of battery, CHECK IT AGAINST THESE DIMENSIONS.
    Beyond the size, performance may or may not be as good as the recommended battery type.
    Remember also that Billet Box Vapor recommends the use of protected batteries.

    Q. Can I use <brand/model> batteries?
    A. See above.
    There are many CR123 / 16340 batteries on the market that may or may not fit, and may or may not work well.
    Anything other than what is recommended in this FAQ or on the Billet Box web site, is up to the user.

    Bottom line: The recommended AW ICR 123 batteries are ALWAYS a safe bet.
    Anything else is beyond the scope of this particular FAQ.

    Q. Where can I get the recommended batteries?
    A. Recommending vendors is beyond the scope of this FAQ.
    An internet search for "black AW ICR 123" should find a number of dealers.
    Online forums are also a good place for up-to-date dealer recommendations.

    Q. The batteries fit in there awfully tightly. How do I get them out?
    A. The recommended method of removing the batteries from the Billet Box is to remove the back plate and smack the battery compartment over the open palm of your hand.
    Yes. Smack it on your hand.
    Done properly, at least one battery should drop out allowing easy removal of the remaining battery.
    Prying them out with a tool is not recommended as it could damage the battery.
    Also, recommend removing any rings from the hand you are slapping into, as rings can make dents in the Billet Box chassis.
    Some users recommend wrapping a bit of tape around the batteries to create a handle to pull them out. Thin tape is recommended due to the tight clearances inside the Billet Box.

    Q. Can I charge my batteries inside the Billet Box?
    A. No. Batteries must be charged in a dedicated battery charger.

    Q. What battery charger should I use?
    A. Any charger capable of charging 3.7 volt CR123 / 16340-sized batteries should work.
    Recent widely used brands include Intellicharger i2/i4, EFest LUC and XTAR chargers.


    Q. What is the voltage range of the Billet Box?
    A. The Billet Box has an adjustable voltage range of 4.0 volts to 5.5 volts.

    Q. What is the amp limit of the Billet Box?
    A. 3 amps.

    Q. What kind of power protection does the Billet Box provide?
    A. The Billet Box is protected against over-voltage up to 12 volts, current over 3 amps and reversed polarity. If this internal protection is tripped the user is protected against catastrophic failure, but the Billet Box may have to be returned to Billet Box Vapor for repair.
    Also, in the event of a major battery failure the body of the Billet Box is designed to vent gas through the air intake holes(on the side) and the seams of the back plate.

    Q. With the tank on the inside, are the power components of the Billet Box protected against liquids?
    A. Yes, to some degree.
    The compartment containing the power regulator is sealed with a gasket material.
    However, it is still possible for liquid to get in via the voltage selection dial, in the event of a large spill or leak.

    Q. Does the Billet Box have variable wattage (VW)?
    A. No. You cannot set a specific wattage for the Billet Box.

    Q. My Billet Box won't fire! What do I do?
    A. Common causes of Billet Box misfires include:
    - One or both batteries are not fully charged.
    - One or both batteries are not fully or correctly installed.
    - One or both batteries may have protection circuitry that is not be compatible with the Billet Box.
    - Cartomizer is faulty.
    - Rebuildable atomizer coil has opened or shorted.
    - Atomizer or cartomizer center pin is not contacting the atomizer pin in the tank compartment.
    - Center pin in tank compartment is dirty or oxidized and needs to be cleaned or scraped.
    - Brass Ring is not fully seated on top of or in the cartomizer or atomizer.
    - Brass Ring may be dirty or oxidized and requires cleaning.
    - Atomizer or cartomizer is not long enough to properly mate with the Brass Ring.

    The Billet Box FAQ:
    By Vapian, Version 1.3, May 2014
    Graciously reviewed/edited by Drunk_J & Katdarling


    Q. What type of atomizers or cartomizers does the Billet Box use?
    A. The Billet Box was designed for standard 35mm, 510 connection, metal-bodied cartomizers.
    It is also capable of using some cartomizer-sized rebuildable or replaceable atomizers such as the Atmistique Diver V1, Diver V2, and Billet Bridge; and the user-designed, coop-built Sabot-DDD (production limited to one run of 100 as of May 2014).

    Q. What resistance of atomizer or cartomizer should I use in the Billet Box?
    A. The Billet Box is designed primarily for use with 3.0 ohm cartomizers to provide the best combination of versatility and battery life, though users have reported success with higher and lower resistances for both atomizers and cartomizers.

    Q. Can I use dual-coil or low resistance cartomizers in the Billet Box?
    A. Yes, but this can result in shorter battery life.

    Q. Will my <insert make/model here> atomizer/cartomizer work in the Billet Box?
    A. If a device is sized the same as a standard 35mm 510 cartomizer and the body is a conductive metal, then yes. Otherwise, not likely. If you are not sure, buy samples to test before buying in quantity.

    Q. Does the Billet Box require "punched" or "slotted" cartomizers?
    A. Yes, either/or. You may buy pre-punched or slotted cartomizers or punch or slot your own.

    Q. Where should I punch or slot my cartomizers?
    A. Billet Box Vapor recommends punching a hole about 8-11 mm above the bottom edge of the cartomizer body. If that does not work well, try different locations until it does.

    Q. Can I use "Mega" or "XL" cartomizers?
    A. No. Cartomizers longer than 35mm will not fit.

    Q. Can I used flanged cartomizers?
    A. In some cases, yes.
    Most flanged cartomizers are "Mega", "XL" or "DCT" cartomizers and too long to use. But if length is OK and if the flange does not prevent contact with and seating of the brass ring, or make the atomizer side connection too long, it may work.

    Q. How does the cartomizer screw into the Billet Box?
    A. It doesn't. When the brass ring on top of the Billet Box is screwed down it contacts the top of the cartomizer to make the ground connection, and the positive post of the cartomizer is pressed down on to the positive atomizer connection (at the bottom of the tank compartment).

    Q. Can I use cartomizer-sized clearomizers or clear cartomizers?
    A. By design, no. The Billet Box uses the cartomizer body as part of the electrical path, so it must be conductive.

    Q. My cartomizer or atomizer tastes burned/dry.
    A. Please phrase your question in the form of a question.

    Q. Fine. WHY does my cartomizer or atomizer taste burned/dry?
    A. Sometimes a cartomizer just sucks. Try a new cartomizer.
    For cartomizers this can occur because the fill material in the carto was not well primed or is not being properly wetted during use. Most users report best results by filling with 25-30 drops and waiting 10-30 minutes before use (ensuring all fill material is thoroughly saturated).
    For atomizers this could be poor wicking, or a number of other issues that are beyond the scope of this FAQ.


    Q. What is the Billet Box tank made out of?
    A. The Clear Billet Box tank is made out of strong, food-grade materials. The body is Delrin, the clear face is Polyethylene terephthalate (PETG), the gasket is silicon and the screws are stainless steel.
    The Delrin tanks use the same materials, except the face which is made of Delrin instead of PETG and is translucent, not clear.

    Q. Will the tank hold up to strong/acidic e-liquids without cracking?
    A. Though VERY rare, tanks with PETG faces may, with very strongly acidic liquids, exhibit some cracking over time.
    At this time there have been no reports of Delrin faced tanks being damaged due to e-liquids.

    Q. How much liquid does the Billet Box tank hold?
    A. The tank holds about 5 ml of e-liquid. The cartomizer holds about 1 ml, for a total capacity of about 6 ml.

    Q. How do I install a cartomizer in the Billet Box tank?
    A. Billet Box Vapor recommends priming the cartomizer to ensure the cartomizer is thoroughly wetted before use.
    Lightly wet the upper and lower O-rings with a drop of e-liquid.
    Insert the top of the cartomizer into the bottom of the tank and push it in.
    There is a slight ledge near the inside top of the tank. Wiggle the cartomizer a bit to position it to sit on that ledge and it will more easily push through the upper O-ring.
    Push the cartomizer in just until the bottom of the cartomizer body is flush with the bottom of the tank.
    Some users highly recommend the use of a cartomizer insertion tool, which may prevent damage to the tank O-rings and prevent leaking.

    Q. How do I install the tank in the Billet Box?
    A. First, ensure the brass ring at the top of the Billet Box is backed out several turns or removed.
    With the cartomizer installed, simply drop the tank into the space provided for it.
    Tighten down the brass ring until it snugs up against the top of the cartomizer.
    Once installed, put a thumb or finger on the face of the tank and push toward the top of the Billet Box. It will not move much if at all, but this can help ensure everything is seated and aligned properly.

    Q. How do I fill the Billet Box tank?
    A. There is a small hole blocked by a spring-loaded black Nitrile ball in the upper left face of the tank that the included, plastic 20 ga Luer dispensing needle will fit into.
    Do not use metal needles (either blunt or sharp), as these will damage the Nitrile ball and cause leaking!
    Place the tip on the end of your syringe and fill it with e-liquid.
    Carefully use the tip of the plastic dispensing needle to push the ball down and out of the way until the tip of the needle is inside the tank.
    Slowly push the liquid from the syringe into the tank. Leaving a small air bubble in the tank is recommended.
    When done, pull the dispensing needle out of the hole. The black ball will block the hole again.
    Wipe any e-liquid residue from the ball or face of the tank.
    Using a finger, gently push on the face of the tank several times to ensure the black ball has fully seated in the hole. This will ensure the tank does not leak.
    You may notice some bubbles coming from the holes or slots in the cartomizer. This is normal and a good indication that liquid is entering the cartomizer.

    NOTE that a ball-less tank is available, that has no filling hole and cannot be filled this way. With the ball-less tank, the tank must be removed from the Billet Box and the cartomizer must pushed partially out of the tank and filled from the resulting opening, as with most standard cartomizer tanks.

    Q. Too many words. Got video?
    A. Yes. Go to and select "Videos". The rest is left as an exercise to the reader.

    Q. Do I have to fill the tank through the filling hole in the front?
    A. If the tank has a ball (most do), is installed in the Billet Box and you don't want to remove it, then yes.
    If the tank is not yet installed or you don't mind removing it, you can fill it just like any other cartomizer tank as described above or by using a tank-filling tool or extended drip tip to push the cartomizer down and fill it from the top.
    Life is all about having options.

    Q. Do I have to use the included dispensing needle to fill the tank?
    A. It is highly recommended. The ball is made of soft Nitrile and can be easily damaged by metal tips. A damaged ball may not seal and could result in liquid leaking from the tank.

    Q. Where can I get more 20 ga dispensing tips?
    A. Amazon or eBay are good sources, especially if buying in bulk.
    Online vaping stores are beginning to carry them as well. An online search for "20 ga plastic dispensing needle" will turn up a fair number of sources.
    Note that these dispensing needles are color-coded for various sizes, and that Pink is the color designated for 20 ga.

    Q. How should I clean the Billet Box tank?
    A. Usually, a rinse with warm water is all it takes.
    If a strongly flavored liquid becomes trapped between the tank body, face and seal, cleaning with white vinegar or effervescent denture tablets may be needed.
    Do NOT use HOT water (above 130 degrees) when cleaning a CLEAR faced tank! This can cause the PETG tank face to become deformed by the Nitrile ball and spring. Even a slight deformity can lead to a leaking tank.
    Delrin-faced tanks do not have this problem.

    Q. What size O-ring does the Billet Box tank use?
    A. According to Billet Box Vapor, 1.5 mm x 9.0 mm inside diameter (12.0 mm outside diameter).

    Q. Is there anything else I need to know or should be careful of?
    A. Yes.
    When using a clear-faced Billet Box tank, Do NOT Leave The Tank In A Car On A Hot, Sunny Day.
    Temperatures in a car can easily exceed 120 degrees and cause the same problems as cleaning in very hot water.
    Delrin-faced tanks are less affected by this, though heat expansion of liquid in the tank can still cause leaking through an atomizer or cartomizer.

    Q. Can I use the Billet Box tank on other mods?
    A. Well, you could, on a mod with a 510 connection that extends out long enough, but ... why?
    If you really want to do this, some devices may require a 510-510 adapter/extender due to the airflow tab on the bottom of the tank face.
