TGIF All.
So my 24v 280AH battery bank has been working flawlessly for the last year however I noticed 2 cells seem to charge faster/more than the rest and it shuts down BMS.
Wanting them to be more balanced, I decided to dissassemble it, put them in parallel, and top balance them with a 10amp bench charger ... goal was to get them to 3.6 so as not to "push it" and then re-assemble the bank. BTW when in the RV I use conservative min/max charge with my LV2424 but the 12/24 1oAmp DC to DC charger seems to want to go 3.65/cell.
After 6 days of 4-6 amps - battery bank is only at 3.4v
I have a trip planned - how long from 3.4 to 3.6? Not sure of the math as the charger will slowly push less juice as battery tops off.
Thanks!
