BMS8 is a intelligent BMS designed especially for 3S - 8S LiPo/LiFe battery pack, it has a microprocessor to detect and balance each cell voltage of the 3 to 8 cells in series.

The unit can balance the battery while charge discharge or at stand alone mode.

Nixie display indicator display each cell voltage, battery pack voltage, difference of cell voltage and the balance state of the battery pack.

Cooperating with charger, the built-in software can detect the cell voltage in charging or discharging.

Besides independent balance mode, you can connect any LiPo or LiFe charger to the input lead first, then connect the BMS8 to the balance connector on your pack, finally connect the output leads to the discharge wire of the pack.

Feature：

1. Automatically detect and display battery balance status for any 3 to 8 cells pack
2. Over voltage protection during charge
3. Under voltage protection during discharge
4. Over temperature protedtion during charge or discharge
5. Over current protecdtion during charge or discharge
6. Short circuit protection
7. Nixie display indicator display each cell in balancing
8. Automatically cut-off the charging or discharging while any cell is over charged or over discharged
9. With Special Connector Conversion Board(CCB-9KT) to fit all kinds of battery connectors
10. Low quiescent current design, BMS8 draw current from all cells, the power consumption is less than 1mA.
