15s vs 16s | DIY Solar Power Forum
SparkyJJO said: But do the math. 15 / 4 = 3.75. You could make 3 sets of 12V batteries from a 15s battery, but have 3 cells left over. If you got a 16s battery, and split it into groups of 4, then you''d have 4 sets of 12V batteries, no cells left over. But really, if you want 12V batteries, just buy 12V batteries.
