12V 60A lifepo4 charger 36A power lithium battery charger 110V-240V 12.6V14.6V quick fast adapter(NO BATTERY)
Special instructions for 60A /50A /85A/100A chargers: 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, 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 (you can adjust the voltage in combination with a multimeter. The display will have a small error.).
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) If the voltage is displayed and the current becomes zero, it means that it is fully charged.
Step3: When using it later (the voltage has been set for the first time, no need to set it later) ------- connect the battery first (very important, it can protect the charger) ------- then connect the power supply- ---------Follow this step for later use, no need to adjust the voltage and current (unless you want to modify it)
Do not adjust the charger voltage while charging. The voltage of the charger itself fluctuates, and it is normal to charge the battery with constant voltage. When the battery is fully charged, the current on the charger display will show zero or near zero. If you do not understand, please consult customer service
To extend the life of the charger. The charger has a voltage of 220V, and the maximum recommended current is 90%, for example, 60A. It is most suitable to adjust it to about 54A. The maximum recommended voltage and current of 110V is 80%, and the maximum recommended voltage and current of 100V is 70%.

The usage of the 40A charger is as follows: Step 1: Connect the power supply first---adjust the voltage you want (use the supplied screwdriver to adjust the voltage in combination with the multimeter)-----then connect the battery------the charger The display will go out---unplug the power plug and plug it in again---------a normal display indicates normal charging.
The second step (the voltage has been set for the first time, no need to set it later) ------- connect the battery first (very important, it can protect the charger) ------- then connect the power supply--- ------- Follow the second step for subsequent use, no need to adjust the voltage and current (unless you want to modify it)
