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
2. Support regenerative braking, during braking operation can charge the batter pack and the discharge power
(Wh) will decrease to response to the braking power.
3. Charge/discharge current up to 300A. Bigger current can be customized.
4. 1.2A per cell balance current is very useful for large capacity battery pack, the feature can resume all cell
voltage balance status at the shortest time. Over temperature protection make sure the system safety
5. BMS8T calculate and display the charge and discharge power (Wh), generally the battery rated power is
rated voltage multiply 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 a maximal safety protection, within the range parameters can be setup, BMS8T will alarm
and cutoff charge or discharge according to users’ setup, out of range of parameters, and trigged absolute
maximum ratings BMS16T will force to cutoff charge or discharge to prevent the battery from fire.
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 cells or external power supply.
10. Detect cell count at any time, and compare with the count detected when switch on first time. If it is not
uniformity, the device will alarm and cutoff charge or discharge according to users’ setup, the feature can
prevent any cell connection from loosing.
11. Sound alarm and LED alarm will be triggered when any warning events happened, and then wait several
seconds cut off or Don't cut off charge or discharge. The delay time can be programmed.
12. Charge relay and discharge relay are controlled independently.
13. Two temperature sensors monitor battery temperature on different position.
14. Supports upgrading the firmware program by USB port.
15. BMS8T provide users the maximal flexibility, key parameters can be programmed.
16. BMS8T display battery SOC or called battery gauge similar with car dashboard. Cell count, battery pack
voltage and battery gauge (%) is displayed simultaneously.
17. In case that the battery pack need not be charged and discharged, Press STOP button enter into sleep mode
to save energy consumption, at this mode, Charge and Discharge is forbidden, and LCD back light is 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 resume “ON”.
1. Cell count error protection
