Remarks: The LED indicator alarm can be enabled or disabled through the host computer,
and the factory default is enabled.
1. When the BMS is in sleep state, press the button (3~6S) and release it, the protection
board will be activated, and the LED indicators will light up sequentially from "RUN" for
0.5 seconds.
2. When the BMS is active, press the button (3~6S) and release it, the protection board will
be put to sleep, and the LED indicators will light up sequentially for 0.5 seconds from the
lowest battery indicator.
3. When the BMS is active, press the button (6~10S) and release it, the protection board
will be reset, and all the LED lights will light up at the same time for 1.5 seconds.
4. After the BMS is reset, the parameters and functions set by the host computer are still
retained. If it is necessary to restore the initial parameters, it can be achieved through the "
restore default value" of the host computer, but the relevant operation records and stored
data remain unchanged (such as power, cycle times, etc.).
