NOTE: Buy BMS and charger combo can save 20usd.  The charger C3060B can charge 1S-8S LiFe battery at 60A 1500W.

The Chargery BMS8T is designed especially for LiPo, LiFe and LiTo battery packs applied to Energy Storage   Systems and Electrical Vehicles including E-Motorcycle, E-Scooter and so on. The unit can measure or detect the battery voltage, cell voltage, charge & discharge current, battery temperature, and battery SOC (State of Charge), with the information displayed on the TFT color LCD screen.  It has an Internal balancing function to balance cells to maintain optimal operations of the battery pack being managed. 


1. The BMS8T uses advanced ADC measurement technology, high accuracy, high voltage and high current detection circuit. The maximum voltage measurements tolerance is within 5mV at up to 8S LiPo battery (34V)

2. Supports regenerative braking, during braking operation it can charge the battery pack and the discharge power (Wh) will increase in response to the braking power.

3. Charge/discharge current up to 600A. Larger current support can be custom ordered.

4. 1.2A per cell balance current is very useful for large capacity battery pack, this feature can restore all cell voltage balance in the shortest time. Over temperature protection ensures the system safety during balancing.

5. BMS8T calculates and displays the charge and discharge power (Wh), generally the battery rated power is rated voltage multiplied by rated battery capacity.

6. TFT LCD screen provides rich information including current, voltage, power, capacity, battery status, SOC and temperature and so on.

7. BMS8T features maximum safety protections, within the range parameters that can be setup, BMS8T will alarm and cutoff charge or discharge according to users’ setup, out of range parameters and triggered absolute maximum settings BMS8T will force cutoff charge / discharge to protect the battery.

8. Minimize the power consumption by draw current from all cells or external power supply.

9. Dual power design, the unit can be powered by all the cells or an external power supply.

10. Detect cell count at any time, and compare with the count detected when switched on first time. If inconsistent, the device will alarm and cutoff charge or discharge according to user setup, this is a safety feature is if a cell becomes loose.

11. Sound alarm and LED alarm will be triggered if any warning events occur, it will wait several seconds, then disconnect charge / discharge if required. The delay time can be programmed.

12. The Charge and Discharge relays are controlled independently.

13. Two temperature sensors monitor battery temperature for different positions on the pack.

14. Supports upgrading the firmware program by USB port.

15. BMS8T provide users the maximum flexibility, key parameters can be programmed.

16. BMS8T displays battery SOC as a dial gauge. Cell count, battery pack voltage and battery gauge (%) temperature is displayed simultaneously.

17. In case the battery pack is not to be charged / discharged and put into storage mode, Press STOP button enter into Sleep Mode to save energy consumption, Charge / Discharge are disabled and the LCD back light is turned off. Press any key to resume normal work mode.

18. LCD back light ON time can be programmed to save energy, when it is OFF, press any key to activate.
