cell voltage, charge discharge current, battery temperature, and battery SOC (State of Charge) , displayed with
TFT color LCD.
Safety Notes
Please read the entire manual completely before using, to make sure you can use this device better and more
safely.
1. Ensure the BMS program and settings match the battery pack, otherwise the battery will be damaged and a
dangerous situation may arise, especially for Lithium batteries, which may cause fire.
2. For storage energy system application and for Electrical vehicle application will have many differences,
please adjust those key parameters carefully, or contact us for more details.
3. Do not allow water, moisture, metal wires or other conductive material into the device.
4. Never charge or discharge any battery having evidence of leaking, expansion/swelling, damaged outer cover
or case, color-change or distortion.
5. Do not try to charge “non-rechargeable” dry cells.
6. Do not mix batteries of different types, different capacities or from different manufacturers.
7. Do not exceed the battery manufacturer’s suggested maximum charge and discharge rates.
8. Carefully follow the battery pack manufacturer’s recommendations and safety advice.

during balance.
4. BMS16Pro calculate and display the charge and discharge power (Wh), generally the battery rated power is
rated voltage multiply rated battery capacity.
5. TFT LCD screen provides rich information including current, voltage, power, capacity, battery status, SOC
and temperature and so on.
6. 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.
7. Minimize the power consumption by draw current from all cells or external power supply.

8. Dual power design, the unit can be powered by all cells or external power supply.
9. 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.
10. 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.
11. Charge relay and discharge relay are controlled independently.
12. Two temperature sensors monitor battery temperature on different location.
13. Supports upgrading the firmware program by USB port.
14. BMS16Pro provide users the maximal flexibility, key parameters can be programmed.
15. BMS16Pro display battery SOC or called battery gauge similar with car dashboard. Cell count, battery pack
voltage and battery gauge (%) is displayed simultaneously.
16. 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.
17. LCD back light ON time can be programmed to save energy, when it is OFF, press any key to resume “ON”.

battery pack must be 8S to 16S LiFe or LiPo. But if power by external power supply,
BMS16Pro can do 2S-16S LiPo or LiFe battery pack. The main input supply Vin voltage range
is 15V to 60V
External power
port
External power input, the voltage should be 15V to 60V, 1A maximal, the current depends
on the external load, the connector is 5.5*2.1 DC jack
Charge controller
Charge controller, turn on or turn off charge circuit, generally connect to relay or DC
contactor. When any cell voltage is over setup, it will not power the coil of relay and turn off
the charger, otherwise BMS16Pro will output Vin power the coil to close the relay. The relay
must be form OPEN.
Discharge
controller
Discharge controller, turn on or turn off discharge circuit, generally connect to relay or DC
contactor. When any cell voltage is under setup, it will not power the coil of relay to turn off
the motor or other load, otherwise BMS16Pro will output Vin power the coil to close the relay.
The relay must be form OPEN.

Warning
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.

Current Sensor and Relay Connection
WARNING
Before connect the relay to charge or discharge controller, please confirm the coil voltage,
the controller will output Vin to power the coil, if the BMS16PRO will be powered by external
power supply, Vin is external power supply output voltage, if powered by battery pack, Vin
will be battery pack voltage, so need voltage regulator to power coil.
Heavy RED wires are positive of battery pack (B+/B16+), charger and load such as motor, and
heavy black wire is negative of battery pack(B-/B1-), charger and load. one heavy wire is for
50A maximal charge current, and 3 wires for 100A continue to discharge.
