Here is a 3 minute video of the smoke that comes out of a 12S2P 20C Lipo, 4 bricks pack: http://www.youtube.com/watch?v=5MsVqcy4k6Y
Wrapped with compression tape on thin foam sheets, not banged up that I am aware. Batteries had been balanced 10 rides ago, last month. 4 months old, probably 40 or 50 rides of less than 10 miles. Use a 3 Amp charger, when I took it off the charger right before the short ride it was 49.8 volts probably 68 degrees F. Don't think the pack was overcharged or discharged too low ever, but can't be sure about individual cells. Was using a small amount of regen during the ride. Cooled the smoking batteries down with snow, only three got trashed, but all are now needing proper haz mat disposal. Probably took 30 minutes for the smoke to stop. Heard some hissing sound while riding up a small hill, pulled over and pulled the pack away from the recumbent trike into the snowy field. Luckily it was not near people.
What is the best replacement batteries, does it really matter 30C, 40C? I think I need 12S4P. Don't want this to happen again. Thanks in advance for most reliable safe suggestion.
I figure there will be some reply flames of the type that "you don't know what you are doing" (which is true), and "I never balance". Give valuable suggestions to the group. Thanks in advance, hope this helps someone.
