Voltage Current Adjustable Lifepo4 Lipo Li-ion Lithium Battery Charger 3.65V 4.2V 8.4V 12V 12.6V 14.6V 75A 50A Display 2S 3S 4S

Voltage Current Adjustable Lifepo4 Lipo Li-ion Lithium Battery Charger 3.65V 4.2V 8.4V 12V 12.6V 14.6V 75A 50A Display 2S 3S 4S

Note: (Important things are repeated three times!)

Connect the battery positive and negative can not be reversed (Red Positive + ; Black negative - ), the reverse will be bad, no warranty! The reverse will be bad, no warranty! No warranty!

Instructions:

The first step: the charger should not be connected to the battery, turn on the power, adjust the voltage knob to adjust the voltage, refer to the voltage display above the display screen, (4S lifepo4 battery 3.65v*4=14.6 volts, 3S li-ion lipo battery 4.2v *3=12.6V), adjust to the voltage you need.
Step 2: Adjust the current to a minimum. After connecting the battery, adjust the current from small to large and adjust to the current you need. (In the charging process, it is not allowed to adjust the voltage knob again, otherwise overcharge or undercharge will occur)
If the voltage is displayed, the voltage you set, the current becomes zero, and it is already full.

Lead-acid battery charging precautions:
Lead-acid batteries do not support high-current charging, and should be charged with a current of 1/10 of the capacity. For example: a one-hundred lead-acid battery, you need to charge with 10 amps! The time must be 8-10 hours, the time is too fast, the current is too large, it will damage the battery. The lead-acid battery charging voltage is about 14.4 volts. The battery manufacturers are different. The voltage is slightly different. The instructions on the battery label shall prevail! Can also Baidu query!

Note: The goods are handmade, the appearance may be slightly scratched

Input voltage: AC 100v/110v --220v/250v

Input power: the new version750W. Old version 675W

Output voltage: DC constant voltage meets 11V-14.8V (suitable for 3S Li-ion Lipo and 4S Lifepo4)

Output current: DC constant current is adjustable to 1-53A. Old models 1-50A (only constant current and constant voltage can be used as charger)

Protection method: After the positive and negative poles are short-circuited, stop the output. (The current knob is adjusted to the minimum to the off state, and then restarted to resume)
