Depending on what type of trailer you plan to connect to your vehicle, you will often need an auxiliary battery and a trailer battery charger. A trailer battery charger is essential for keeping your auxiliary battery charged and ready to power your equipment.
What Is A Trailer Battery Charger, And What Does It Do?
If you plan on running a trailer and need to power electronics, you may want to add an auxiliary battery and a trailer battery charger. A trailer battery charger like REDARC’s BCDC1212T is designed to make sure that your trailer has a constant and efficient power supply so you can power all of your electronics.
The REDARC BCDC1212T 12A trailer battery charger is designed to charge your auxiliary trailer battery to 100% state-of-charge while on the move. Connecting directly to the trailer plug, the BCDC1212T provides 3-stage battery charging for optimum battery charge, protecting the truck's start battery from discharge while charging the auxiliary battery responsible for operating winches, hydraulic pumps, dump trailers, liftgates and boat trailers.
Running cabling from your tow vehicle's starter battery to the trailer would require long cabling - that would normally result in voltage drops. A trailer battery charger is a form of DC-DC charger that is usually mounted in your trailer. The DC-DC charger can handle a long cable from the tow vehicle's starter battery to the auxiliary in the trailer without voltage drops.
