Cmax Battery cells are great, but they are too small for traditional busbars so a PCB busbar simplifies the process of building a 14s1p 48v battery pack. Project requires 2 PCBs, the busbar pcb and the BMS pcb.
Here is the list of parts you'll need to complete this project:
* 14x C-MAX Cells- https://jag35.com/collections/new-arrivals/products/c-max-hybrid-fusion-batteries-panasonic-lithium-cells-3-7v-5ah
* 1x Buss PCB -https://www.pcbway.com/project/shareproject/cMax_48v_5Ah_battery_module_Project
