hi all,
i am embarking on a new project, building a outdoor rolling credenza that has TV, cd player, small receiver, 100% wireless (power and wifi, etc).

my design calls for a battery pack that can deliver approx 5x106​ joules, this leaves me in the ballpark of 12v@115Ah, or 48v@29Ah
in general this is 200watt x 6hr @ 85% system efficiency.

true sine wave inverters run best at 48vdc, but a 12v inverter can also work.

(12v inverter) can i run 12v Lithium batteries in parallel if they are isolated via diodes and the charger has four independent cell chargers,
or, four 12v Lithium batteries in series for 48v (can a 4 cell charger straddle each cell in series and be ok?),
or do i source one 48v ~29Ah battery

any suggestions?
