Chargery BMS16 is designed special for LiPo LiFe battery pack applied to storage energy system and
Electrical Vehicle 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) , 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.

BMS16 Special Features
1. The BMS16 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 (69V)
2. Charge/discharge current up to 300A.
3. Support regenerative braking, during braking operation can charge the batter pack and the
discharge power (Wh) will decrease to response to the braking power.
4. BMS16 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 that provides rich information including current, voltage, power, capacity, control
status, SOC and temperature and so on.
6. BMS16 features a maximal safety protection, within the range parameters can be setup, BMS16
will alarm and cutoff charge or discharge according to users’ setup, out of range of parameters,
and trigged absolute maximum ratings BMS16 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. BMS16 provide users the maximal flexibility, key parameters can be programmed.
15. BMS16 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.

Power Selector
Alternate External or battery pack to power BMS16. If select all cells power the unit, the
battery pack must be 8S to 16S LiFe or 8S to 14S LiPo. But if power by external power supply,
BMS16 can do 2S-16S LiPo or LiFe battery pack. The main input supply Vin voltage range is
13.5V to 60V
External power
port
External power input, the voltage should be 13.5V to 60V, 1A maximal, the current depends
on the external load, the connector is 5.5*2.1 DC jack, the external po er supply and
charger should not be common ground.
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 to turn off the
charger, otherwise BMS16 will output Vin power the coil to close the relay. The relay must be
form OPEN. Chargery Charger is recommended to save the relay cost and control the charge
better.
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 BMS16 will output Vin power the coil to close the relay.
The relay must be form OPEN.
Temperature
sensor
Two temperature sensor monitor the battery temperature, the sensor must tie to battery
surface or gap of cells where the temperature should be the highest during charge or
discharge. The temperature range is 0-150℃
LED Connect to high light LED, the LED will flash when any warning event happened
Beeper Connect to beeper or others to alarm. It will output 12V 25mA max.
Current sense Connect to current measurement module that is designed special for BMS16. Charge current
and discharge current can be measured by one module.
USB Connect to PC update the firmware by Chargery UpdateTool.exe
Socket 1 Connect to 2S to 8S battery,
Socket 2 Connect to 9S to 16S battery. for over 8S battery, please connect 8S battery to socket 1 and
then connect to socket 2, such as 8S + 2S for 10S and 8S +5S for 13S
Absolute maximum or Minimum ratings
Maximal cell voltage LiPo 4.35V Larger than the absolute maximum voltage, BMS16
will force to cut off charge
LiFe 3.90V
Minimum cell voltage LiPo 2.50V Less than the absolute minimum voltage, BMS16 will
force to cut off discharge

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 NOT controlled by BMS16, but when
cell voltage and temperature trigger the absolute maximum
or minimum ratings, the BMS16 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 BMS16 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.
