BMS & connecting multiple lifepo4 batteries in parallel

DanielVictor · Mar 31, 2020

I want to order qty 3: 12v 100ah lithium battery and connect them in parallel. Each battery comes with its own bms. Do I use only one bms for the entire system or configure all 3 bms's. I am a bit confused.

In parallel, you have three independent batteries and each has its own BMS.

I am clear that each battery has its own BMS. So then I guess I will need to set the parameters of each BMS independently right?

Yes, each BMS is a little controller that manages the 4 cells in each battery.
I would expect that if the batteries are the same that you would set the BMS parameters the same. Each BMS will function independently so one BMS may disconnect its battery if one of its cells gets out of working range.

Thats what I was thinking. Thanks
