Description:
This DC-DC battery charger is engineered for versatile mobile power systems, ensuring both safety and efficiency. It features built-in alternator detection to charge only when the engine is running, preventing accidental drain of the starter battery during vehicle idle. Compatible with flooded, gel, AGM, and lithium batteries, it also offers a user-defined mode for customized settings. Equipped with an advanced BT-2 bluetooth module, it allows convenient remote monitoring and adjustment of settings via the DC Home app. Comprehensive protections—including overload, short-circuit, overvoltage, and overheat safeguards—plus intelligent thermal power management ensure reliable, high-efficiency charging in all conditions. Ideal for RVs, trucks, commercial vehicles, boats, and yachts alike.
Features:
- [Temperature Compensation]: The battery temperature sensor provides real-time data to optimise charging parameters for peak performance.
- [User-Friendly Layout]: Safe spacing between input and output terminals minimises the risk of accidental short circuits.
- [Lithium Battery Activation]: Enable or disable lithium activation via the app based on battery condition to extend lifespan.
- [Efficient Heat Dissipation]: Ventilation holes ensure low-noise, efficient cooling to prolong service life.
- [Wall-Mount Design]: Compact, lightweight wall-mountable design fits easily into any tight installation space.
