[RE-wrenches] LFP storage

[Darryl Thayer]

I have some experience. I have a customer that had a parasitic load on for
3 years, I warned him, now he wants to use the battery and it is dead and I
can not get them to recharge,  Another customer with the same battery has
had them on float, at 80% of full charge voltage battery works fine.
