4. OPERATION
Once the batteries are connected well, simply press On/Off button to enable the output of the battery pack.
1.Switch on: press On/Off button to switch on the battery, then the battery will do self-inspection before
enable output. The LED will show the SOC.
2.Switch off: press and hold On/Off button for 3 seconds, the battery will shut down directly.

Remark
①
: 1 in SW1-SW5 indicates ON status, and 0 indicates OFF status.
Remark
②
: When multiple battery packs communicate, the last battery pack SW5 needs to be in the ON
status, otherwise the communication may have interference.
Remark
③
: When the battery pack ID is set to 0, it means stand-alone operation, and it is not necessary to
detect whether the parallel condition is satisfied
⑤
Remark
④
: When the battery pack ID is set to 1-15, it means that the parallel operation is required, and it is
necessary to detect whether the parallel condition is satisfied
⑤
Remark
⑤
: The parallel condition is that the difference between the battery voltage of the local battery and
all the battery pack voltages is <3V, otherwise wait until the condition is satisfied
