As the title suggests I accidentally left my @psychotiller 12s5p (charge-only BMS) board on for a few days and it got drained completely. The board won’t turn on, and when I plug the charger in it flashes red for a second then goes back to green. A couple other chargers I plugged in just seem to flash red a lot. Anyone know what’s going on? Did I kill the pack by draining it too much?
