Hi.
A 3P10S 18650 (panasonic) battery pack.
Charged using a Turnigy charger, cell by cell.
All cells took the same amount amperes.
Total voltage of the pack = 40,3 volts
Just replaced the BMS because I thought it was the faulty part.
When plugin in the BMS, voltmeter show between 3,8 and 3,9 volts for each cells while BMS is plugge in. BUT the output of BMS = 0,01 volts. Any idea why ?
I've applied a load to each cell one by one (a 12v automotive bulb), voltage of the pack stayed at 40,3 volts. So I doubt that a cell is weak in go quickly under the 2,7 over-discharge protection voltage when I plug the BMS, which could make the BMS cutoff. Plus the BMS should cutoff the cutoff when each cell comes back over the 3 volts from over-discharge recovery voltage.
I've really no idea...
