Charge your trailer batteries with this 12amp dump trailer charger from REDARC.
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.
The BCDC1212T comes pre-wired with wiring harness allowing easy installation into any typical trailer battery setup, or other trailers where the secondary battery’s charging current is drawn from the 12V Auxiliary Power available on a pre-installed, suitably rated, trailer plug and towing harness.
Suitable for 12 or 24v systems and all battery chemistries. Installation requires a 23amp on the input and a 30amp fuse for the output. Fuses can be found here.
