got my small tube of deoxit gold in (lol could only find 1 store that has them locally.. hoorah for audio junkies and their gold plated contacts .. how much of this stuff do i need to apply and how often ?

Do you mean like a small container like this?

Did it come with a couple of applicators that look like q-tips but with foam instead of cotton on the end?

Use just enough to create a thin layer on the battery and then using a micro fiber cloth I wipe off the excess. I made sure to try and clean my batteries as much as possible before applying the DeoxIT and I wipe my batteries off before charging them, then when they are going to be used again I just do a quick reapplication and wipe down before installation. Has been working for me, no messy Nolax and no more oxidation issues (well I also did the "Paired Contacts.")

Btw...just poking around for parts...check these out 10 Pcs Car Audio Mini ANL Fuse Auto Stud Fuses 20A Amp | eBay

Hmmm.

Just how long does it take for our batteries to start venting at, say 40A or 70A? My old fuse experience only encompassed fast-blow and sensitive electronics, but my gut feeling says these are OK. So are these Quigsworth approved?

Actually, I'm running my REO without a fuse, but I have pdib's car fuse in his mod.

 

[Quigsworth]

Those blow times on over current are fine...we only really need a fuse for a dead short...and when that happens your current will skyrocket...you'll bump up against the pulse amp capacity of the batt...then the batt's chemistry will start to kick in choking the current at that level (destroying itself in the process)...but none of that really matters cause the fuse would have popped a long time ago, even if the fuse held in there for a second (or even 2) your batt would survive that...just don't go nuts with the fuse...I run 10's...even down to .3 I haven't had a problem...

I keep looking for this YT vid but I can't find it...some dude dead shorted an AW IMR and tossed it in a baking sheet and watched it (just to see what would happen...)...from what I remember not a lot did...it got pretty hot, bulged and hissed a bit but that was about it...and this went on for mins....pretty anti-climactic actually

My hat goes off to those who build mods on a mass produced level...spreading myself between so many different things is pretty arduous.

Got around to fixing the stationary contact to allow for maintenance free(ish) use of the VTC5 at 0.30Ω and below.

In my haste to install the screw I forgot to change bit sizes and made the pilot hole in the delrin the same size as the the mounting hole on the stationary contact... it works for now but not as clean as I had intended...maybe when I get bothered enough I will redo it to my standards but wanted to give you guys an idea of what I was going for.

I filed down about 2-2.5mm on the delrin piece to allow for my qtip to fit in above the stationary contact and wipe any oxidation present but after 4 HEAVY days of using this as my only mod I had one tiny speck of oxidation that wiped away very easily, so if I clean this once a day or every battery change I dont forsee any degraded performence issues like before. Oh and the batteries had no oxidation on the postive terminals at all

I have been working on a fuse holder for those low profile mini fuses I mentioned last time but it isnt that high of a priority since things work well for now and I enjoy the use of the spring in battery removal and installation.

Quigs, I ran across some old posts of yours in the modders section, no more regulated mods in your stable? I am building a couple of VV box mods and something else a lil special....

nice job on that connection GreatestU




i bought an abrasive pencil from the local auto shop, it's fiberglass fibres running the length of a pen looking jig and has a twister on the top to adjust the length of fiberglass, short is more abrasive, i didnt know if you guys have seen these things but i picked one up and when i got home i cleaned the 510 connections, firing pin and battery terminals, hitting so frigging hard again




i can get into the female part of the 510 on the reo real easy with it and can even run around the threading with it.

on the bottom of that card it also sais you can get refills online.. happy dayz

 

[SLIPPY_EEL]

Bimini are you not using a fuse in the reo? if not, what are you using?

i presume using battery magnets would be ok? << thats to anyone.

Right guy's, i understand the way the Voltage is with two batteries in a series & parallel circuit but what about the Amp's, can someone tell me please

Parellel: Amp limit is doubled, voltage stays the same (technically not doubled but the load is shared between the two batteries....)
Series: Amp limit stays the same, voltage is doubled ( lead battery takes the brunt of the load so ensure to rotate the lead battery after charge cylces)

Nice find...I'll be getting one of those for sure...

One of the clearest explanations I've seen...the paralleled 18650 mod I built (then forgot at a pub 3 days later ) to hold a pair of VTC's was a great platform to experiment on, there wasn't a whole lot (short of being insane that is) that it couldn't handle and still keep a high level of comfort...obvious problem is where do you put the bottle? (I hate dripping)...plus the semi mech aspect of running a "switch" is an issue, I made it so it could be replaced pretty easily but now that I'm on to the paired contact thing there really is no reason why I couldn't bus the pos. terminals to one contact point...hmmmm

Really? So, those parallel boxes aren't necessarily 8.4 volts?

Hah! That's interesting.

Unless there's some sort of regulator in it I'd really be surprised.

I say interesting, because KZ (Instagram) promotes 8.4v. At least that's what my brother that owns a KZ box says.

When using batteries in parallel you also increase the mAh but the voltage does not increase. Without looking inside of the mod I couldnt tell you if it is truly parallel or series, but we all operate within the world of electricity and an unregulated parallel circuit with a 3.7-4.2V cell cannot produce 8.4 V

I've always been a little skeptical about it. I've hit a .1 ohm coil on that thing without a flinch... If that was pushing 8.4volts, that would be ~700watts...

I didn't feel dead.

 

[Quigsworth]

There's pros/cons to both series and parallel set ups…considering watts are V x A(I)...in a series set up, you double the voltage which means you have half the current…the lower current results in lower VD from cct resistance issues (relative to source V), not to mention your hardware doesn’t have to be built to take say 10A (which is great if you’re a switch)…if it wasn’t for the fact that you also have 2x the batt res. to deal with series is actually the better alternative from an overall equipment stress and personal safety perspective…but making 2 -3 ohm coils just seems weird now and voltage drop-off is dramatic on series set ups

However if you can spread the load over a couple batts in parallel, you now have “a lot” less batt resistance to deal with (same reason why 2x 1 ohm coils gives you .5 ohm overall) and seeing as the instant heat up of kanthal is a product of current flow not the potential (voltage) across the coil, the more grunt you have the quicker it gets up to temp especially if you are running 26 or lower wire. Cct resistance (Vdrop) is a bigger issue but you have the power capacity to plow through it so meh, and you don’t have the issue of rotating batts to keep them balanced…at the end of the day, I’d rather run two good batts in parallel, even though the math may show otherwise because our vaping experience is current based (heating coil) not voltage based, now if they could figure out how to jam a 400 cold cranking amps car battery into a mod I’d gladly go to 12v.

Just got an email froma B&M in my area about some new batteries...I havent had a chance to try and find out more specs than what is given on the website:

 

[Quigsworth]

I've seen them on Ebay and VH carries them...I don't know, I guess I'm just so interjaded I don't believe anything anymore...my thought is if a 40A (run, not surge) could be done, one would think a company with the R&D resources like Sony, Panasonic, Samsung, LG, etc, etc...would have done it...

I'm not saying it's not a quality batt that's been re-wrapped...well, I guess I just did

...It just seems like there's a cloud chasing sub-ohm "arms race" going on atm...when there's hype and trend, the desire to cash in is just too great...but hey, I could be totally wrong...definitely wouldn't be the 1st time

just sayin'

Here's some info I found from the WSJ
The California based company, which develops, produces and sells electronic cigarette products such as custom vapors, high quality e-liquids, and exclusive vaporizer adjustments, proudly announced that the release of its custom designed battery has sold out. The product was displayed at the World Vapor Expo in Miami and also at the Vape Summit, which was held in Las Vegas.

The Vapor Hub International Inc (OTCMKTS:VHUB) announced selling 2,000 units of The Vamped Vapor Cell, which are 40 amp 18650 batteries at the events. The cells were priced at around $7 per unit. Vapor Hub announced that the battery was well accepted by not only the vapor stores that were present at the expos, but also by the community.

Addressing Market Needs

Vapor Hub International Inc (OTCMKTS:VHUB)’s Chief Operating Officer, Kyle Winther, said that the product was a result of his endeavor to design a superior battery that was immediately available to vapor stores across the world. He said that traditional batteries required him to place orders with Chinese brokers and then wait for around 3 to 6 weeks because the batteries were mostly out of stock. This drove him to manufacture and source quality batteries, he said. He seeks to address market need for these cells and expects to provide it with readily available supplies. Winther claims that the company’s newly designed and manufactured cells are the most powerful 18650 batteries available in the market.

Vapor Hub International Inc (OTCMKTS:VHUB)’s Director of Sales, Justin Moreno, said that the batteries, which will provide customers the desired level of amperage, are sourced directly from the manufacturer. He added that the company’s present capacity is 120,000 a month. The company also aims to sell the batteries in the global battery with delivery promise of the same day, so as to satisfy customers’ needs.

Wall Street hyperbole...IDK

It's just a stock LP Grand with the upgraded contacts and spring. I haven't done any modifications to it, yet.
