NOTES:
1. Always on means the LCD back-light will be ON forever.
2. NO means BMS16T will not cut off charge or discharge but alarm by LED flash and Beeper Sound.
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 BMS16T, but when cell voltage and temperature trigger the absolute maximum or minimum
ratings, the BMS16T will force to cut off charge or discharge to make sure the battery safety, and prevent
battery pack from explode or fire.
3. Current Calibration is not recommended unless use
new current shunt. Voltage and current is calibrated
before delivery.
4. Temperature Alarm OFF means battery temperature and
Difference of battery Temperature is unable.
5. Cell Empty Voltage and Cell Full Voltage is to set up cell
voltage bar graph, the value should be as same as Over

6. Setup the battery start voltage, when minimum cell
voltage over the setup, balance will start automatically
7. Setup the minimum cell difference, when difference of cell voltage under setup, stop balance
automatically
8. Balance switcher, default Balance is OFF,
a) If balance in storage setup ON, balance will start in storage status, STORAGE means charge or
discharge current under 1A. So the current shunt and current sensor wire must be connected to
BMS. When driving the car, balance in storage OFF is suggested. For storage system, ON is better.
b) If balance in charge setup ON, balance will start in charge
c) If balance in discharge setup ON, balance will start in discharge
d) Balance current is 1.2A max. per cell,
Balancer
BMS16T can resume cell voltage balanced status at the shortest time, it is based on 1.2A balance current per
cell, balancing accuracy is 8mV. Balance can be operated in Storage, in charge or in discharge or in all status,
the feature can be setup on program setup menu. The balance function is disable before delivery, after the
BMS display each cell voltage, please enter into program setup menu to enable balance.
Although balance current per cell is larger than other brand BMS, Chargery BMS16T use temperature
protection prevent BMS from overheating, and has a over current protection for each cell.
