Hi
Does anyone have experience of Relion lithium batteries? I am especially interested in Relion InSight GC2 Lithium that states it can be charged down to -20C. Or the RB100-LT as I understand it has a built-in heater that first heats the battery to correct temp before charge. The downside of RB100-LT being that it can’t connected in series to get 48v.
