Batteries
I built two 14S11P Split Packs, one with Molicel P42A and one with P45B. To make them fit the through the screw hatch, I used a offset pattern for cell arrangement. I designed an Printed the cell holders and end caps. 7S is a bit more tricky than 6 (or 8S), as one of the busbars has to be at the bottom of the pack. I used 0.2mm nickel strips to spot weld the packs. Terminal leads are 6AWG with QS8 antispark connectors. I also put an ntc inside to log the battery temp (connects to motor temp input of vesc and logs as motor temp in metr).
I didn’t like the way the strip got bent to the poles of the cells so I built a 3D printed press template to create a recess.
