High Power Battery Charger, 0-120V Upgraded Design LifePO4 Battery Charger, One Click Control Adjustable Current/Voltage for LiFePO4 Lithium Iron Rechargeable Battery((0-25A)

* Special instructions for 100A charger: First, plug the charger into the power supply. Look at the voltage ---- Adjust the voltage ---- Connect the battery ----- Adjust the current.
Step 1: Do not connect the battery to the charger first. Turn on the power and adjust the voltage knob to adjust the voltage. Refer to the voltage display at the top of the display screen, (4S lifepo4 battery 3.65V * 4=14.6V, 3S lithium battery 4.2V * 3=12.6V). Adjust to the voltage you need (you can use a multimeter to adjust the voltage. There may be slight errors on the display screen.).
Step 2: Set the current to the minimum value. After connecting the battery, adjust the current from small to large to the desired current.
(It is not allowed to adjust the voltage knob again during the charging process, otherwise overcharging or undercharging may occur, and the host may burn out.) If the voltage is displayed and the current becomes zero, it indicates that it is fully charged.
Step 3: For future use (the voltage is set for the first time and does not need to be set in the future)----- Connect the battery first (protecting the charger is very important) - then connect the power supply. Follow this step for future use without adjusting the voltage and current (unless you want to modify it)
Do not adjust the charger voltage during charging. it will charge the battery at a constant voltage. When the battery is fully charged, the current on the charger display screen will display as 0 or near 0.
NOTE:
This product is a one click control product with key on/off, current setting, voltage design, and timed shutdown.
*Turn on: Rotate clockwise one circle;
*Shutdown: Press and hold the power button for three seconds; (Other numerical options can be adjusted by lightly pressing the button to select.)
*Timed shutdown: You can set the time after selecting it. After fully charging, it will automatically stop after the set time.
*Fully charged will automatically stop charging.
WARNING:
1. At100-110V, total power 1500W. For example, when using 60V, the current can only reach 25A; If 30V, it can reach 50A.
The charger uses an AC input voltage of 220V-240V, with a total power of 3000W and a current regulation of 80% -90%. For example, 50A, 50 * 0.9=45A
Do not use at full current for a long time, such as 60A. To protect the lifespan of the charger, do not maintain a working current of 60A all the time, and do not place the power cord of the charger on the power socket for a long time.
2. Adjust the appropriate voltage before use. After connecting the battery, it is not allowed to adjust the voltage, as this can easily damage the charger.
For example, after connecting 14.6V to the battery, the display will display approximately 13V. This is a normal phenomenon. Don't worry, and don't adjust the voltage. When the battery slowly charges, the voltage will increase. It will end at 14.6V. A current of 0 indicates that it is fully charged.
**3. This charger is mainly suitable for use with lithium iron phosphate batteries. If lead-acid or lithium batteries need to be charged, the current output is recommended to be 10%, otherwise it may damage the battery or cause other safety hazards. Please use it carefully!

Do notconnect it backwards when charging.
If you find that the positive and negative connections are reversed, please remove them immediately. At this point, the possibility of the machine being damaged will be very low. If reversed for a long time, it can cause the power supply to burn out. Be careful when using.
The charging mode has a battery Anti Reverse Connection Function, and the output relay is in a disconnected state. If the battery is not connected, the output will automatically close and the output relay will be disconnected.
The power mode cannot be connected to the battery in reverse. The output relay is in a lo
