Thanks for the info Don. I may have screwed up. I have ordered 240 of the Molicel 42a planning to split them as you have done but in 2 sides of 20s6p. I also ordered the DALY Smart BMS 20S 72v 80amp. How is your BMS set up on this build?
Sorry everyone, just learning how to reply. Don I have a question on your battery for this build. There is a picture showing some copper strips soldered on cells sitting in a box. Are those copper strips designed to function as a cell level fuse?
