I'm probably just not wording this correctly, but here's my use case:
Existing 48v 200ah lifepo4 battery bank (2p16s fortune 100ah cells, overkill solar bms), charged with hydro and solar. We stay between 80-100% soc typically thanks to the hydro.
I want to add another 48v 100ah (16s) battery that will live in an electric golf cart. I want to connect this in parallel to the existing bank to recharge, however, how do I limit the inrush between the high SOC and low SOC batteries? I realize I could charge this with a "charger" but then I'm going DC-AC-DC which seems silly. There must be an elegant way to do this DC-DC, right?
