    Not sure if they really are Samsung cells. According to a discription from the contacted manufacturer it is missing information in the wrap and on the cell itself. -SAMSUNG SDI Confidential Proprietary – Spec. No. INR18650-30Q Version No. 0.0 Wanmook, Lim - 15/16 - Additional remarks ■...

    lipo battery pack wiring with pics

    I used a propane soldering iron and flux and tried to be quick. There were about 5 cells where I sat with the solder and iron for about 10 seconds to get it to stick. I was hoping to close this off within the bike and charge it through a port so it doesn't have to be touched. I'm going to...

    lipo battery pack wiring with pics

    It's a 1 1/2” piece approx. Folded in 1/2 twice. Should I add another or use something different all together? What is a 60/40 solder job? Drawing of parallel connections added. Can I leave the battery assembled with it connected to the charger and controller and use/charge is as is?

    lipo battery pack wiring with pics

    I'm not happy with the solder as well, but after trying 3 separate spot welders and all three not working I decided to try and solder as quickly as possible to avoid transferring too much heat. I received the cells in new condition, the spot weld marks were from my attempts with the 3 failed...

    Can I use packs with different cells for more power?

    I suppose you both are right. Better to be safe than sorry. I'll just let the customer know they need to upgrade the battery beyond budget if they want more out of their bike. Thank you for your input.

    Can I use packs with different cells for more power?

    Say the 30q cells have a higher discharge rate than my mystery cells and , would this only cause the bms to stop all battery packs from being used, leaving the mystery cells with partial charge? Then I'm assuming i would need to charge separately due to the voltage differnce. My initial battery...

    new cyclone 3000 w mid-drive kit?

    I'm new and still learning all the specifics, but would this work? I know they're cheap knock off crap at best. But would two of them make a useable 72v 20ah battery. I'm not worried about them lasting long, I'll lget the warranty coverage plan so when they fail i can get them replaced or my...
