Special Features

1. The BMS16Pro 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 16S 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 600A. 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
during balance.
5. BMS16Pro 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. BMS16Pro features a maximal safety protection, within the range parameters can be setup, BMS16Pro will

alarm and cutoff charge or discharge according to users’ setup, out of range of parameters, and trigged

absolute maximum ratings BMS16Pro 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 NOT 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 location.
14. Supports upgrading the firmware program by USB port.
15. BMS16Pro provide users the maximal flexibility, key parameters can be programmed.
16. BMS16Pro 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. Charge and Discharge is cut off, 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”.

Cut-Off Delay Time is very important and difference for different battery capacity and application, please
carefully test and make a correct decision, for EV, you can select NO to control the EV car by manual NOT
controlled by BMS16Pro, but when cell voltage and temperature trigger the absolute maximum or minimum
ratings, the BMS16Pro will force to cut off charge or discharge to make sure the battery safety, and prevent
battery pack from explode or fire.
