1. Pulse width modulation

2. Temperature compensation

3. Auto detect and display battery capacity level

4. One-click quick fast charging(Designed for emergency situation-About 30min)

5. Convenient hanging style

6. Suitable for 48V/12AH or 24AH lead battery or gel battery of electric vehicle .

The electrical motorcycle charger is designed by the characteristics of the battery which is made with pulse width modulation and temperature compensation.The new technology of pulse stock and over temperature protection can efficiently reduce Heat generation of the battery,which can greatly extend the service life of the battery.With three-phase charging mode,anti-reverse protection,which enables it to charge more quickly and safely.This product is suitable for electric vehicle 48V/12AH or 24AH lead battery or gel battery.



1.Temperature compensatory:According to the ambient temperature,the battery charger can automatically increase or decrease the battery charging voltage until the battery capacity is literally full.

2.Charging mode:Firstly,the normal charging mode(default),the maximum output current is 2.5A.Secondly,the fast charging mode,the maximum charging current is 3A,which is only designed for emergency situations,and it will resume normal charging mode automatically after 30 minutes.

3.The built-in intelligent MCU can easily control the management of the battery charging will automatically stop charging when the battery is full.

4.It adopts efficient three-phase(constant current phase,constant voltage phase,floating charging phase)PWM charging mode.

5.Auto battery detection function,short circuit/overcurrent/overvoltage/reverse polarity protection.

6.The detailed charge indicator shows charging process directly and facilitates understanding the current state of the battery.


Three-phase charging mode

Constant current mode: When the voltage of the battery is lower than the value set by the charger,the charger will work under the constant current mode and supply the constant current for the battery.

Constant voltage mode: Using the pulse width modulation(PWM) tech to control the charging current and output voltage of the charger which ensures the battery is fully charged and avoids over charging.

Floating charge mode: When the voltage of the battery is approaching the value of the constant voltage mode,and the current will cut down to the given current gradually,that means the battery power is full, then the pilot lamp will turn green and the fan will stop working.The charger will turn the mode into floating charge mode automatically.At this moment,the battery can be stopped charging or keep on floating charge for half an hour.
