Our Battery Management System (BMS) is made up of a printed circuit board which monitors and manages the 4x 3.2V lithium cells to ensure they are charged and discharged together and at the same rate. It also provides protective features to prevent over charge and over discharge of the cells, keeping the battery within a safe operating envelope. Our innovative BMS is also designed to be able to draw up to 250A on the load side and charge at up to 100A.
