I have a V1 Boosted Board with a broken battery.
Some of the cells have discharged down to 0V and I wanted to ping the experts here on approaching cell revival before I start trying to rebuild the pack.
( unfortunately, due to utterly and stunningly incompetent design by Boosted, leaving the board unattended for a few months will cause the packs to discharge to complete zero )
Can a LiFePO4 cell be recovered from 0V?
I applied a constant current power supply to one of the cells at 0V by tapping into its ends directly in the exposed pack, and at 400mA the PSU was only developing ~0.7V to drive that current. Leaving it for several hours did not yield a voltage increase.
Is this a sign that the cell is dead?
Should I expect it to take a higher current pulse to begin the revival?
