    There's a few tips that I learned along the way with building Milo mods.

    First, the easiest way I've found to remove the onboard fire button is to use wire snips and clip the 2 legs of the fire button closest to the edge of the board, then rock the button back and forth til the other 2 legs break away from the board. A LOT easier than de-soldering or dremeling the button off.



    And for the cover, I've been using a 0.118" piece of black transparent arcylite... you can buy a sample size for only a few bucks that will make 2 covers... no need for tinting paint or window tint film...

    And for the screws, I've been using switch plate screws - much nicer than the ones that come with the case...

    Did you start your DNA on fire? ....Long story but on one of my DNA's I lost the connection through the DNA board, but the charger still works hooked directly to the battery.

    Have you tried hooking the charger directly to the battery?

    Also what type of battery are you using? I tried using the battery pack out of an itaste MVP that has some kind of protection circuit or something on it and the DNA charger wouldn't charge it, but would charge regular lipo cells.

    I'm pretty sure I'm the epitome of mentally challenged sometimes and have done just about everything wrong with these as you can.

    Anyway I can say that if you short the output of the charger while it is energized you end up with a fancy usb red led

    It's easy to test the output with a meter, but I believe it needs to be disconnected from the DNA board or battery removed as I believe you will read the battery voltage at the charge terminals if memory serves.

    LOL bap and retird - looks like we've all been there had that happen.

    So... one of three things...
    - funky batt... replace batt

    - funky charging board... replace charging board

    - funky charging connection at DNA board.. by-pass the DNA board's charging connection and connect the charging board + and - directly to the + and - batt connections

    AWESOME thread... thank you, Mamu, for the awesome write-up and all of the Q&A you've done here and elsewhere in this section!!

    Endeavoring on my first DIY mod, so I may have some questions for you along the way. I have an engineering background and I generally take to these things quite nicely. Plus, I'm a total geek and I absolutely LOVE to build things! After my Milo is done, I'll be vaping with a mod I built, on an atty I constructed, with juice that I've brewed. Pretty cool to think about considering I started with a 180mah manual button 510 in 2009 : P

    I DIGRESS... Are these the batteries you used? http://www.ebay.com/itm/2x-25C-3-7V-...item3a66563ad5

    $16 shipped... 3 weeks or so from Hong Kong. Any better options? I found some that looked almost identical to the ones in your PDF how-to, but they're only 20c

    http://www.ebay.com/itm/2-X-3-7V-100...item1e7c377e04

    Can I trust these "straight from China" batteries in terms of safety and longevity?

    If you are getting from Hobbyking they have a USA warehouse and the 2200mah are in stock there last I checked. You have to find the one that is marked USA warehouse. The 97mm is ONLY the grey foil area, the tabs are another ~10mm in length. But I believe you can fold them back along the pack to save some space; I would say 100mm is about as tight as you want to go for just the battery.

    As for trusting these, there haven't been too many reports of well-built mods having problems with LiPo packs but they are inherently less safe than for example IMR batteries, and even ICR round cells because of their metal casing. The Groove's LiPo pack getting punctured was apparently the reason for the failures/fires.

    As for whether Turnigy is a reputable brand, it is a low cost Chinese brand but it appears to be fairly well regarded. They do have the hobbyking contract which is apparently a pretty big thing. The RC guys run into their share of issues with Tunigies (and other LiPo brands) but their battery packs tend to see more physical abuse than ecigs would tend to see. For them, the hard case packaging makes sense, but even those can fail due to crash impacts.

    In the end you are sacrificing some safety for price and power with any LiPo. But I believe most builders are at relative peace with that if they build well and put in their own safeguards (fuses, boards that have low voltage cutoff, chargers that work, etc.)
