Of course, tell us the model you need in the order notes and we can take out the BMS for you (Note: only for boxes shipped from China)
What types of prismatic lithium iron phosphate batteries is this box suitable for?

It is suitable for standard square battery cells such as 280/302/304/314Ah. Please contact us if you would like to know whether other battery cells are compatible.
