China 48V 20A Portable Electric Tricycle Battery Charger

Instruction

Working principleCharging characteristics
This charger adopts Iu-Ia charging curves with programmable intelligent control and high efficiency for charging. So the battery can reach an excellent state and prolong the battery life.
ChargeProcedure
Step1 Charge with the maximum current , and go to next stage until reach the setted voltage value.
Step2 Charge with method of constant voltage. The current value will decreases, when the current is reduced to the setted current value .
Step 3 Charge with method of constant current until reach the next stage
Step 4 Charge with method of constant voltage. The current value will decreases, when the current is reduced to the setted current value .
Step 5 Charge with method of constant current until reach the end.Features Working time (8-11 hours): Charging time depends on the charging current, the rated capacity, and discharging level.
Low voltage protection: When battery voltage falls below the setted minimum, the charger refused to charge.
Overvoltage,overcurrent protection: When battery voltage, current is abnormal, the charger refused to charge.
Overheat protection: The overheating of the charger can lead the charger not to work.
Equalization Charging:The charger run to Equalization Charging automatically after 15 cycle charging .
