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 just remembered something - often (and more likely the older the device is) - the battery consists of an array of standard cells which can be bought separately. So if you feel adventurous you can pry the battery open, unsolder the cells, test each one separately - chances are there’s just one that’s completely dead, thus making the whole thing unusable.
I remember hearing that you can’t solder batteries normally though and that a special technique is needed to heat them minimally. Is this true?
