Can a battery be connected to the "load" output of a MPPT 75-15? Will it damage anything?
I wish to charge a second lithium bms protected battery when the primary mppt 75-15 charge voltage gets to near full battery voltage. I would let the secondary battery bms control charging it's battery. I'm trying not to us an Orion or other dc/dc converter. I searched but didn't find a definitive answer. Thanks.
