Found this cute little guy. Battery bms seems to either be dead or cell voltage too low. Has anyone in the Linux community revived a BMS before or recharged from zero?

    i have dissasembled batteries to recharge the 81650 cells inside then reassemble. If they drop below a certain threshhold then the protection circuit won’t charge them. I have a special charger/tester for lithium cells and a battery tab welder. It’s only worth it if the replacement is unavailable and it’s for something very rare.
