Product Description

⚡

DC-DC charger that can charge the main battery through the alternator, and starter battery, or Solar panels charge the main battery (some models). Designed specifically for motorhomes, campers, ships, etc.

B2B Charge Technology

🚗

It means to charge the main battery through alternator and starter battery. If it is not used in the vehicle, you can also use one battery to charge another battery.

When the vehicle is running, the vehicle alternator can quickly charge the main battery through charger at full power.
The charger can charge the main battery according to the specified voltage and current by boosting or stepping down to ensure that the main battery is in accordance with the standard charging curve.

MPPT Solar Charge

☀️

The charger can increase the charging efficiency of the solar panel by 10-30% through MPP technology (Maximum Power Point Tracking).
Ensures the main battery is charged according to the standard charge curve by boosting or stepping down voltage as required.
Maintains a small trickle charge flow for the starter battery when the vehicle is idle for long periods, ensuring sufficient power to start.
