Convert 48V battery bank to 12V for boat appliances - Is this inefficient?
But how much would I lose in terms of efficiency? Would the losses be too great?
Would the bank of 4 x 12V 100AH batteries connected in series give me roughly 4800W ( 4 x 12 x 100 = 4800) or 16 hours of 300W use when drawing only 12V after the conversion? Or would the available AH be much less due to the losses from the conversion?
