Description:
This high-performance 660W DC-DC battery charger is designed for mobile lifestyles in RVs, cars, boats, and yachts. It supports dual-input charging—either from the starter battery via the alternator of the vehicle or directly from solar panels—ensuring your service battery stays fully charged in any setting. Built-in MPPT technology maximises solar efficiency, while a three-stage smart charging algorithm (bulk, absorption, float) safely and accurately charges gel, AGM, and lithium batteries to 100%, extending their lifespan. An integrated Voltage Sensitive Relay (VSR) intelligently isolates starter and house batteries to prevent interference and guarantee reliable engine starts. Comprehensive protections—including temperature compensation, overvoltage, overcurrent, overheating, reverse polarity, and reverse current—ensure complete safety for both device and batteries
Features:
- [Temperature Compensation]: Equipped with a temperature sensor port for precise compensation in extreme heat or cold, ensuring stable battery charging.
- [Remote Monitoring Device]: Monitor remotely and receive real-time updates via the BT-2 bluetooth module and the DC Home app anytime, anywhere.
- [Efficient Heat Dissipation]: Die-cast aluminium housing enables efficient, low-noise cooling to significantly extend its service life.
- [Soft-Start Circuit Design]: Gently powers up the charger to protect equipment and prevent draining the starter battery.
- [Removable Side Cover]: Anti-static cover prevents ESD damage from human contact, ensuring long-term safe operation.
