BulletPoint6 : ✔【Special instructions for the 60A charger】: first plug the charger into the power supply-----look at the voltage---adjust the voltage-----then connect the load-----and then adjust the current. Step1: Do not connect the battery to the charger, turn on the power first, adjust the voltage knob to adjust the voltage, refer to the voltage display at the top of the display, (4S lifepo4 battery 3.65 v*4=14.6V, 3S lithium battery 4.2v *3=12.6V) , adjust to the voltage you need. BulletPoint7 : ✔【Step2】: Adjust the current to the minimum. After connecting the battery, adjust the current from small to large to the current you need. (It is not allowed to adjust the voltage knob again during the charging process, otherwise there will be overcharge or undercharge, which may burn the host at your own risk.) If the current on the display becomes zero, it means it is fully charged. BulletPoint8 : ✔【Charging】: During the charging process, the voltage of the display screen will drop, which is a normal phenomenon. Do not adjust the voltage of the charger while charging. In order to charge the battery with constant voltage, it is normal for the voltage of the charger itself to fluctuate. Adjust the voltage and current for the first time. No further adjustment is required later. If you do not understand, please consult customer service!
