LIFEPO4 Battery discussion thread

Roughly 300mV deviation still. It still cuts off early when other batteries are at 20% soc so still a problem but not as bad as when I got it.

That is also why I tend to topup often to give it more of a change to balance and see if it wants to improve.

You never left it on the power supply to balance for 2 days?

No just 1 day.

No just 1 day.
