60V 20AH Power Supply Adapter Smart Electric Bike Motorcycle Charger Rechargeable Lead Acid Battery Charger DC 74V 3A US

Microprocessor Control (CPU).
3-STAGE AUTOMATIC CHARGING:
This is a fully automatic battery charger with 3 charge stages.
Automatic charging protects your battery from being overcharged. So you can leave the charger connected to the battery indefinitely.
3-stage chargers are suitable for most lead acid battery:Calcium, Gel and AGM, Wet batteries. They may also help restore drained and sulphated batteries.

5:Protection for battery charger
Over Voltage Protection:The power supply will be auto recovered when faults remove
Over Current Protection: Charger output current does not exceed the set maximum battery charging current.
Over Short Circuit Protection :Battery charger output can be shorted without damage No odor, smoke, fire, plastic deformation, and excessive heal happen. The power shall be auto-recovery. (It will enter into normal condition when then the fault condition is removed)
Over reverse polarity Protection When the battery charger output line reversed after the charger will not work until the right user access only to start.
