LiFePo4 battery management

Post by dat.ev » Mon, 17 Sep 2018, 11:02

Hi folks,

I'm planning on a 33.2kwh battery pack consisting of 104x CALB 100AH 3.2v cells. One thing I have found is that most of the lithium BMS management systems support a maximum of 8 cells. Does this mean I need 13 individual BMS units? Is there a better way? Maybe there is larger BMS units out there Im not finding...

Thanks in advance.

I see the EV power one only goes up to 312v. Slightly low for my system. Zeva I can only see a max of 16 cells. Can you tell me where you saw the 200 cell one?

EDIT - Looks like the Orion can do it and you buy the controller based on cells required.
