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 back will be bad, no warranty! No warranty!
The charger is CC-CV. When the battery voltage is 90% of the full voltage, the charging current will gradually decrease as the battery voltage increases, until the final full charge automatically stops charging
Instructions:
The first step: the charger must 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 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 it to the current you need. (In the charging process, the voltage knob must not be adjusted again, otherwise it will cause overcharging or undercharging)
When the voltage is displayed, the voltage you set, the current becomes zero, and it is already full.
Precautions for charging lead-acid batteries:
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 must charge with 10 amps! The time should be 8-10 hours, the time is too fast, the current is too large, it will damage the battery. The charging voltage of the lead-acid battery is about 14.4 volts. The battery manufacturers are different. The voltage is slightly different. The instructions on the battery label take precedence! Can also query Baidu!
