When making a "48V" battery out of 18650 cells, why do we use a 14S configuration rather than a 13S configuration?
I never thought about it when I was making my pack, I just excepted what folks did and did it. But, I can never just except something, I am cursed with always wanting to know why. And in doing a video a few weeks back I started to think, why 14when 13 fits the bill?
The 13S configuration would be 52 V top (with a cell voltage of 4.0 V) and 45.5 V bottom (with a 3.5 cell voltage). That is right in the sweet spot for my (and I think most) inverter.
Is it just the result for folks preferring even numbers to odd--which I find odd, or the old superstition of unlucky number 13???
