Hello all, I recently bought 20 of these 9S 32.85V 2.89ah 94.93WH LI-ION PACK + BMS from Battery Hookup for salvage only, and trying to figure out how to make them work. Right now I'm using a cheap Chinese 1500W boost inverter powered by a 12v AC transformer I hade laying around from some outside light system. I'm pushing 36VDC into the pack after a bridge rectifier and I did get a couple to come alive but most are at -0- or some part of a volt. I have taken a couple of them apart and the issues vary. Some have a couple of good cell packs while others are dead, dead, dead. Some have a full charge at the pack but the BMS TX60 shows nothing going out. So anyway I can do this on the cheap? Is it worth it? Can someone recommend a working method to figure out how to do this? I'm just playing around here to try and learn more about all this but would consider this a good learning opportunity before I play around with more expensive equipment.
thanks
Walt

CRAZY PRICE! PERFECT TO SALVAGE CELLS AND ACCESSORIES! THESE HAVE NEVER BEEN USED, IN MOST CASES THE CELLS ARE OUT OF BALANCE. WE USED AN ACTIVE BALANCER TO REBALANCE SOME PACKS AND MANY STARTED WORKING AGAIN SO ITS POSSIBLE YOU CAN GET SOME WORKING AGAIN AS IS BUT THESE ARE BETTER TO SALVAGE...
