I'm building a wiring harness and hub. The goal is to have one centralized BMS (Battery Management System). This one BMS will be able to disconnect all the batteries if any cell group goes too high or too low in voltage. By paralleling (grouping) cells together they will help each other out.
I'm sharing this method and idea, but it's not the only way to do things. My last battery build was de-centralized. I used separate BMS's for each 48v battery pack. It works great also. There are more than one way to wire BMS's. If you prefer to see a build of de-centralized BMS's, check out my build video of a Smart Fortwo Battery.
These modules are Lithium Iron Phosphate, LiFePO4. I bought the large 24v modules from Battery Hookup.
