DC-DC ISOLATED CHARGER

DC to DC Dual-battery Isolated Charger

SBC DC-DC Charger

DC to DC Isolated charger(Dump Trailer Battery Charger) allow drivers to save time on the road by powering the battery whilst driving without needing to pug in the device, it reduces the dependency on AC mains charging. Able to charge Standard Lead-Acid, Calcium, Gel, AGM, or LiFePO4 batteries.

One way to charge auxiliary battery is to use a vehicle alternator, however, modern vehicles usually employ smart alternators designed to shut down when the vehicle’s starter or primary battery is fully charged, which leaves only small power to charge the auxiliary battery, makes it difficult to be fully charged.

By using this Dual-Input DC to DC Charger series, auxiliary batteries are accurately and safely charged from the alternator ensures your batteries are kept at optimum performance levels that will enhance performance and extend their lifespan.

Whilst driving the main battery is charged via vehicle's alternator or solar panel converting power, the main battery can also charge the auxiliary battery by the DC-DC dump charger/battery charger, this means both batteries are recharged as the vehicle is moving, drivers don't need to pull over and wait all the time for both batteries to be charged fully.
