I want to design a 48v system for an RV with multiple Lithium batteries connected in series (either four 12v or two 24v lithium batteries).
I like the idea of a 48v system to reduce the size of the wires needed for the high output inverter.
I would need 12 volts to run some of the systems on the RV (Fridge, lights, etc).
My question is: Would it be possible to connect two DC-DC converters across each of the 24v battery (or battery sets) instead of using a single 48V-12V converter? I'm thinking this would make the lower voltage converters more efficient, but I can't figure out what the impact would be on the output end and the balancing load of the batteries.
