Well… I done fuckered up…
Whenever it was that I “parked” the '02, a year and half (?) ago, I forgot to pull the 4p LifePo4 60Ah green cell “7th battery” pack and disconnect the balance boards. Oops. Periodically I would plug it and the main pack to charge, but never paid attention to that it would “finish” instantly since I couldn’t see the LFP charger to see the charge light go green. Obviously, it was that it was actually below the start voltage for the charger.
When I pulled it last week I discovered all 4 cells were down to 0.3 to 0.0 volts.
Anyone ever try recovering from a situation where the battery sits at 0volts for an extended period of time?
I’ve read/seen that you can trickle charge at about 3v, very low amps, for an extended period and maybe recover the cells. Any factual accuracy to this? Obviously, it’s a crap shoot some batteries will never come back. And the ones that do, are damaged goods.
Any other tricks or suggestions welcome on this to see if I can at least get a few of them to bounce back - I’ll use them for something other than the GEM if they do.
