I seem to be ending up with a stack of cheapo 2S2P light packs that all have the same vault, they won't charge. They seem to be able to discharge down to normal levels where the BMS cuts in Ok. Everything else seems OK and I can charge directly to the battery by bypassing the BMS.
Now in the BMS data sheet it mentions charge recovery voltage. Is the charger over volting the battery, the BMS cuts in, we then discharge the battery and then the BMS is unable to reset that charging over voltage trip out ? If that is the case do we need to bring the battery back up to in this case 4.075V per group of cells or am I miss reading this.
Thanks
