Collection: Battery Management Systems

A Battery Management System ensures that your battery stays safe and generally offers a low voltage cutoff, high temperature cutoff, balancing function, and controlled discharge and charge currents.

BMS are usually small enough to be able to be shipped via letter mail, although there is no tracking and shipments can take longer with letter mail. If you're okay with that, we can ship for FREE! Just let us know after purchase and we will refund your shipping cost!
