Protective and balancing circuit for 7 pcs of Li-Ion cells in series - for packs with total nominal voltage of 25.9 V. The balancing voltage of cell is 4.2V.

Simple Battery Management Board (SBM)

The easiest way to protect a lithium battery pack. The SBM board manages a pack of cells and disconnects the load under any unfavorable circumstances: cell over voltage, cell under voltage.

The SBM is connected between the battery pack and the load and the charger. There are additional wires from single cells to the SBM to monitor each cell. (Marking of the contacts: B+/B- to connect to the battery; B1, B2, B3..... to connect to each cell; CH+/CH- to connect charger (optional); P+/P- the whole PACK (battery with SBM) output to the load.

Voltage of the Li-Ion battery packs:

  • SBM for 4 cells 14V
  • SBM for 7 cells 24V
  • SBM for 10 cells 36V
  • SBM for 13 cells 48V

Please observe the maximal current of the pack including the peak currents when starting or connecting the equipment.

Please check the maximal current of the pack including the peak currents when starting or connecting the equipment.
This SBM is designed for discharging current max. 30A and charging current 5A. You can use the DC contactor for higher currents.

Note: the balancing currents of the SBM boards are very low (only few milliamps), this means it is not possible to balance large capacity cells. We suggest using additional CBU modules to increase the balancing current of the cells.
