Adding LiFePo battery to existing LiFePo bank
Lots still to learn about lithiums for me. I still run GC2s but am getting more exposure to LiFePo.
A friend wants to add a 270Ah Dragonfly to his dual 200Ah Dragonfly setup. Can the added (3rd) battery be larger than the other 2? My old lead brain tells me it needs to be the same battery to balance the charge between them, but these all have onboard BMS so is this still the case? Any certain way to wire them? Or does it matter as long as they are all in parallel?
What about converter/charger limitations? How many Ah is the stock charger good for?
Thanks All!
