Hi,

I have an existing 48volt off grid installation using banks of sealed lead acid batteries. they are taking up heaps of room and i would like to change them to banks of recently acquired lipo 18650 batteries.

question is rather than use a 13s bms, 1 big array of batteries, can i use 4 x 3s bms's in series and put the chargers 55v across the lot?

Cheers
Ian
