Hello
I'm currently building a 28s5P pack for my ME1507 and Sevcon Gen4 Size6 controller for the EV motorcycle I'm building. I've got the batteries on the way (Headway 38120 LiFePo4 cells) and thanks to their phenomenal discharge capacity, I'm fully expecting to be maxing out the amperage of the controller.
My question is on the BMS. I'd like to keep all these cells in good shape and balanced, but I'm confused on the BMS options. Many of them are smaller, only rated for 50A or 100A, but they're capable of my 28 cells in series. Do I need a BMS rated for 600A or can I get away with one that's rated for my continuous use, which is closer to 50A.
Or, can I just not use the high current leads on these BMS's and just use the BMS for cell balancing?
Thanks everyone.
