Simple Battery Management Board (SBM)
The easiest way to protect a lithium battery single cell! The SBM board manages a single LiFePO4 cell and disconnects the load under any unfavorable circumstances: cell over voltage, cell under voltage, overcurrent.
The SBM is connected between the battery pack and the load and the charger. Connect B+/B- to the cell poles and to connect charger or load, please use P+/P- pins.
See additional tips for the installation at the GWL/blog section for SBM
Please observe the maximal current of the pack including the peak currents when starting or connecting the equipment. Max. continuous current provided by this SBM module is 20A!
Note: This SBM module is not determined for balancing the cell. It has no balancing capability at all. We suggest using additional CBU modules to increase the balancing current of the cells.
