The battery pack is finished.
All the 24 cells are connected.
A 1:1 cable from Adaptto BMS board to the two cell boards.
The BMS board is for 28S and will be break out to 24S.
Today I got the PCB’s for the battery pack. It’s looking great!
I got hold of 24 pcs A123 20Ah pouch cells and will build a battery pack with these instead of Headway. 33% more energy and less space. The only downside is that I need to figure out a way to connect them.
I will make 2 pcs of 12S1P pack and design a PCB to connect them to.
