The JKBMS supports up to 24 cells. Easy to config for 16 or 17. This installation runs like a charm. Squeezed another kilowatt out of the bank. 14 kw not 13. I monitor and log every cell every minute, for the last year. Nothing common about 3.2 volts for a cell voltage. That's all new with the new technology. Why shouldn't 17 instead of 16 be the new norm. It is no longer a 2 volt per lead acid cell world.
