Greetings,
Ive got 40x Sony VC7 cells from an ebike pack which was drained by a faulty BMS. The cells were sitting at close to 0V, clearly for a while.
Managed to charge them back up carefully at 25mA and have cycled them 4x since. They are coming out at approx 3000mAh on the OPUS at 1A.
They havnt lost any more capacity. Temperaturesare completely normal.
Sadly they are discharging themselves. After about 1 Month they are down to 3V and would continue draining if left untouched.
I would throw them away but I thought maybe someone here wants to use them for something. Garden lights, torches??
Im giving them away for FREEto whoever wants them but Im asking you to pay the shipping costs, 7,99, Domestic inside Germany only.
Regards
J
