    i somehow got a hold of a bunch of 28GA pure copper braid that seems to handle 5A with ease at work. not to brag or anything... but it's really great powerline wire.

    Default Stripping Battery PCB

    Do you have a tutorial or know of a tutorial for doing this?

    Cheers

    Quality 30 guage stranded wire can handle 1.5 amps easy with lengths of less than a foot.

    it's fairly simple - carefully strip the heatshrink off, do not let ANYTHING metal touch it, and pay extreme care to a thin metal strip running down the side with tape under it. THAT is the pos and can NOT touch the metal casing or it'll arc and you get explodeys shortly after. cut that strip FAST and CAREFULLY and pull it away from the body. after that, desolder the PCB from the negative end and you're done. easy as nitroglycerin pie topped with napalm and candles. ^_^

    a quick tip - i use a cuticle cutter (the V grooved tip ones) to slice through heatshrink with ease if you do need to remove that heatshrink for any reason.

    I couldn't find stranded 30 AWG. The only stuff I could find was solid core "wrapping wire" at Radio Shack. I had an idea to use this with little terminal posts and actually do a wire wrap setup for the neatness and to save room. But that was only for accent LEDs and switches.

    I figured that this would likely be the best place to post this without creating a whole new thread. I followed the tutorial exactly as shown here, and now my pack is built. I triple checked all my wiring and everything is as it should be. Only problem is that I when I plug my pack into the charger I have a constant green light. It's supposed to turn red when it's charging right?

    I built a 7.4 Li-Ion Pack (14500 AA Sized pack) and have a Tenergy Li-Ion Smart charger set to the 7.4 charge setting.

    Any help would be most appreciated!

    Thanks, Psab

    Double check proper wiring and connections.

    And make sure you have polarity correct on the jack/recharge port, and check the connections on your cells.
