Healing cells with high current

To expand on recovering lithium batteries, 0 volts is a stretch to recover so you really have to be mindful if the battery is actually charging is or heating up. Every time i trickle charged for a few sec I checked voltage with a multimeter. I’ve also had rc lipo batteries that basically stopped charging at a certain voltage and started heating up instead, not even recovered ones. So pretty much always treat them as they will go in flames any time.

I have a bunch of sanyo liion cells I use to replace 3S alkaline packs and they routinely get drained to 0 and charged back up again. :fire: :fire_engine: :fire_extinguisher:

Talkin’ like 5-10wh though, not a big esk8 battery pack.
