When buying ,need to leave message that you battery votage and current,so that we can modify the right to you.
Voltage should be adjusted at no-load, and the battery is full current displays as 0.
Charge current regulation
How much current the battery can charge , we must first understand what the charge and discharge rate is, in C;
Charging rate = charging current ÷ battery capacity
Usually our lithium batteries can withstand a charging rate of 0.5C, and some high-rate cells can withstand 1C charging; for example, calculating the current of a 60AH battery with standard 0.5C charging is:
Charging current = capacity X rate = 60X0.5=30A.
So 60AH lithium battery can withstand 30A current charging.
The formula for calculating battery charging time:
Charging time = capacity ÷ charging current = 60AH÷30A=2H
Note: Multiply the capacity by the charging rate at how much current the battery can withstand, and do not charge more than the maximum charging rate. Otherwise, the battery life will be reduced.
Common problem
①How come the voltage regulation has not changed?
Answer: The voltage knob is turned counterclockwise seven or eight times and it will come down.
②How can the casing leak electricity?
Answer: All metal shell electrical appliances are equipped with triangular plugs, in order to ground the shell, as long as your socket is grounded, there will be no leakage. If there is no way to ground it, drying of shoes can also be solved.
③ Will it stop by itself when fully charged?
Answer: Adjust the voltage value to charge, it will stop when it is full.
④Is it normal that the heat sink is a little hot?
Answer: High-power charging will definitely get hot. The fan is a temperature-controlled fan. The higher the temperature, the faster the fan rotates. The charger also has over-temperature protection. If the temperature exceeds the specified temperature, it will reduce the power by itself. Use it with confidence.
