I'm working on making Lithium Ion NCM battery bank. I have total of 16 batteries(cells). The cells are 3.7v and 94 AH each. Plan is to build a 12v system with as much amp-hour as possible. I did some online research and looks like a 4S4P will give me a 12v and 376 AH. But it looks like I'll also need multiple BMS's to achieve balancing, over charge/ over draw protection, High /low voltage protection
Here's my question:
- Is there a cell configuration i can use to achieve 12v with least amount of BMS involved with all the protection and about 250AMP capable?
- What are some good, reliable, somewhat economical BMS brands? I'm somewhat limited in this because my cells are not LiFePo4 which have a slightly different charge profile than Li-Ion (NCM) batteries I have.
Attached is my cell specifications
Thanks
