18650 Li-Ion pack 12S4P with BMS supports

thingiverse

This is the supports I used for my 12S4P battery in my homemade electric drift trike. Video of the build here (in french) : https://youtu.be/mE7GQBkmA5E I also included the 2S2P variant to try and fine tune your print settings or if you also need a 2S2P pack ! I brought 4 extra cells and tested with the highest internal resistance ones. Printed with ABS to handle welding heat and cell temp. It also ease a lot when you screw the two parts in (I used drywall screws) I used SONY MURATA VTC5A cells to have a lot of current, but you can use whatever 18XXX cells The BMS used is a HELTEC BMS 12S split connector : https://fr.aliexpress.com/item/4001170222603.html?spm=a2g0s.9042311.0.0.8cc86c37763d8T
