36V 3A battery charger
Model :IN4203000
Output :42V 3A
Brand :Intai
Product origin :China
Supply capacity :2000pcs/day
Warranty :3 year
This 36V 3A battery charger is designed for bicycle 10S 36V lithium bicycle battery pack of size 14AH or larger. The 36V charger has an integrated microprocessor to avoid overcharging the batteries, maximizes battery capacity and extends battery life. Never have to worry the charger catches fire when used. Laboratory test data show that all internal and external temperature parameters of the charger at full load are within safety standards. When the battery get full, the 36V 3A charger cuts off the output to prevent the charger from being "charged" by the batteries when the main supply is off or any fault occurs. Typical applications include electric scooter, electric bike.

The 42V 3A charger is designed to maximize the life of the 36V lithium bicycle battery. A multi-stage charge profile and protections are implemented to reduce stress on the battery.
Charge Status Indicator of the 36V 3A Battery Charger
Red | ● Charging or disconnect form the batteries |
Green | ● Batteries fully charged |
Red flash | ● Reverse connection with the battery ● Faulty battery ● Short circuit |
When charger is disconnected from the mains, or battery is fully charged, a relay is used to automatically disconnect the charger from the batteries, to prevent the battery from flowing back (Backfeed).
U-shaped heat sinks which fit perfectly with the housing, dissipate heat in an effective way to ensure the charger with long life span.
The 42V 3A battery charger works safely and quietly. With the application of soft start technology, the output is spark free.
