Adopting switch mode design, reverse pulse technology and MCU (micro control unit) system, the chargers are more compact, reliable and advanced. The most important is the reverse pulse technology.

Switch mode: 

Or we call Switching Power Supply, this is different from Linear Power (using in traditional charger). 

1. Conversion efficiency:

More than 85% electric energy was transferred to battery chemical energy during charging process comparing with 40% of conventional charger.

2. Compact:   

           Housing type          Net Weight (kg)        Dimension (mm)

                   1                        7.25                             330*203*129



MCU system:

1.  Automatic charging

2. Multi charging procedures

3. Monitor the whole charging process

4. Polarity & overcharge protection

Prevent the output leads from sparking due to accidental reverse connection or short circuit, and you can connect your charger to battery until next time use, never worry about overcharging.

Reverse Pulse Technology:

Combined with MCU system, chargers generate reverse pulse current during the charging process.

1. Reducing battery internal impedance, gassing and temperature rise, restore the sulfate build up on the battery plate  into liquid to recover battery capacity.

2. Maintain battery, extend battery’ service life and keep battery in shape..

3. Low temperature rise and save energy.

This will helps you to cut considerable costs on battery maintenance. 


Short-circuit protection

Case of output short circuit protection of power supply will enter a status, and failure to lift automatically resume normal.

Polarity protection.

Prevents the output leads from sparking due to accidental reverse connection or short circuit,
increasing safety. 


Besides, all chargers have digital display.

Digital Voltmeter, Ammeter and thermometer will show battery' voltage, current and charger's 

temperature on battery.

We have CE certification of all chargers and more than 20 patents in China.


Full range of our products:  

Output Current: 600MA to 30 A; Output Voltage: 6V to 72 V.
