I found that circuit on EV forum with not much info, and they like resistive balancing better.
Next question is what would be good balancing for RE? Circuit that would balance batteries at discharge and charge if possible.
Since resistive balancing does not make sense.
At list not to charge controllers that we are using,unless is set for 14.5v and a dump controller to 56v.
Or forget everything and build Ghurd controller for each battery.
I am using old batteries now and before I invest in a new set would like to have balancing in place.
Something that I can build and maintain TS45 is on a shelf I like to play.
