the display show “OK”.

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

plug, rotate the plug, and pull out after the slot is aligned.
