Adjustable Charger Lithium Battery Lead-Acid High-Power Battery Charging Charger 30-102V 0-30A 0-45A 0-50A(30V-120V 50A,220V UK)

This is a modified product. Do not order if you are mind
When charger work in110V Country,working Current will reduce half.
When buying ,need to leave message that you battery votage and current,so that we can modify the right to you.

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
Common problem
How come the voltage regulation has not changed?
Answer: The voltage knob is turned counterclockwise seven or eight times and it will come down.
How can the casing leak electricity?
Answer: All metal shell electrical appliances are equipped with triangular plugs, in order to ground the shell
