Battery Management System (BMS）
Overcharge Protection
When the voltage of any single cell or whole battery pack is higher than the set value during the charging, and the duration reaches the limited time, the system enters the over charging protection state automatically, the charging MOS is turned off at the same time, and the battery cannot be charged. After the voltage of each cell and the whole battery pack drops below the cell overcharging recovery value, the over charging protection state is released. It can also be released by discharging to return to normal state.
Over discharge Protection
When the voltage of any single cell or whole battery pack is lower than the set value during discharging, and the duration reaches the limited time, the system enters the over discharge protection state, the discharge MOS is turned off, and the battery cannot be discharged. After the over discharge protection of the battery pack occurs, it can be released by charging the battery pack.
Over Temperature Protection
When the NTC detects the temperature of the battery cell surface is higher than the setting value of over temperature protection during charging and discharging, the management system enters the over temperature protection state, the charging or discharging MOS is turned off, and the battery pack cannot be charged or discharged in this state.
Low Temperature Protection
When the NTC detects that the temperature of the cell surface is lower than the setting value of low temperature protection during charging and discharging, the management system enters the low temperature protection state, the charging or discharging MOS is turned off, and the battery pack cannot be charged or discharged in this state.

Dip Code Switch Definition and Setting
ADD switch is a 8-bit DIP switch to manually distribute the communication
address of parallel batteries.
The BMS will only recognize the DIP address once it is reset, so please reset
the BMS when the DIP address is changed (the BMS must be reset in the standby
state). When the DIP address is 0, the battery is configured as the stand-
alone working mode; when the DIP address is 1, the BMS is configured as the
master working mode; when the DIP address is 2 to 6, the BMS is configured as
the slave working mode.
Please refer to the table below to set the DIP switch for parallel connection
of different batteries.
