I use a MPPT 100/20 with existing wiring to charge LFP batteries. The voltage drop from regulator to battery leads in a reduction of loading current because the MPPT measures the voltage at the regulator itself and not at the battery. But the MPPT knows the current on the cable and could compensate it. Is it possible to configure the device that it knows the resistance of the cable?
Is it possible to set the maximum current in balancing mode? I have 1A balancer but use 20A charging current in normal mode.
