Remark: take photo or video immediately and contact the local reseller or Green Tech if meet any unusual condition.
3. Battery power on & off operation
(1) Battery power on operation
First, make sure that the ‘STOP’ button is not locked and can be rotated，
Press and hold the start switch(5S) until the screen lights up and release the switch. The BMS starts the self-test until the correct
voltage, current, SOC and temperature information are displayed on the screen. The BMS self-test is completed and the battery can
be used normally. If the battery doesn't work properly, please contact the after-sales service engineer.
(2) Battery power off operation
Press the ‘STOP’ button
In case of emergency, please quickly press the stop button to cut off the battery and restart the battery after troubleshooting,
4. Battery External Connection Description
Positive HZ8.0 Negative HZ8.0 Cable 4AWG
The positive socket is orange, corresponding to the orange positive plug, and the negative socket is black, corresponding to the
negative black plug. When connecting the power cable, do not short circuit the positive and negative, so as not to damage the
battery and cause danger.
Please align the positioning slot on the plug and socket and insert it. When pulling out the plug, press the key on the side of the
