I had an idea of how to charge one battery from another with higher voltage until their voltage is equal.
Connect the one with lower voltage at the batter connection of a Solar charge controller like normal.
Connect the higher voltage battery to the solar PV input.
As I understand it, Solar charge controllers are just DC/DC converter, so it should not matter if the Input voltage comes from a Battery or PV panel.
The only possible issue I see is that the Battery could supply at lot off current, but they have an overcurrent protection that is trigger when the MOSFETs inside overheat.
Maybe to be safe, adding a break or fuse is a good idea in case the overcurrent protection fails.
As anyone ever tested this?
