A Battery Management System (BMS) is a key part of a lithium battery. Unlike lead-acid batteries which do not require a BMS, lithium batteries do. A BMS primarily is a circuit board which manages, monitors, controls and protects the lithium cells from being over charged or over discharged, which can lead to permanent damage or in the worst case lead to fire. It also needs to be able to disconnect your battery before the cells go outside of their safe operating limits.  Therefore it is vital that your investment in a lithium battery is not compromised by using an inferior BMS. That is why we have opted to design, engineer and manufacture our very own BMS right here in Brisbane, Australia – so that we can control its functionality, quality and reliability.
