Many people with powered trailers or Hiabs know the hassle of having to charge your dump trailer battery from 240V AC mains power. Having to charge your trailer battery before each use not only wastes mains power but means you’re limited to when and how long you can use the trailer. To free your trailer from the hassle of AC mains charging, REDARC’s purpose-built light-duty DC battery charger is the most advanced on-trailer battery charger on the market and is perfect for installation into Hiabs or any truck or trailer with hydraulic pumps, fridges or winches.
Why do I need an on-trailer battery charger?
In a dual battery setup, where one battery is used to start the vehicle and a secondary battery is used to run electrical devices on the trailer or to power the lift bed, an on-trailer battery charger is essential. The BCDC1212T offers greater flexibility and versatility when it comes to charging trailer batteries, not only in terms of correct battery charging but also suitability for all alternator types including 24V, battery locations, and battery types. This makes it the perfect solution for dump trailers, boat trailers, car trailers, liftgate trucks and camper vans with electrical equipment and accessories.
With many modern vehicles having smart alternators, they don’t produce a high enough voltage to charge a secondary or trailer battery through a direct connection. The BCDC works by boosting the voltage to the second battery to charge it regardless of the alternator type. It’s also useful to overcome voltage drop caused by long cable runs.
What does a trailer battery charger do?
The BCDC1212T keeps the auxiliary battery charged whilst driving, ensuring your secondary battery is fully charged no matter the type. It is compatible with 7-pin round plugs and sockets, allowing it to be used with existing 12V auxiliary power available on the trailer plug. It works in both 12V and 24V vehicles and is ideal for trailers that have hydraulic pumps and winches.
The BCDC1212T allows you to save time and keep moving by powering the battery throughout the day whilst driving and reduces the dependency on AC mains charging. Able to charge Standard Lead Acid, Calcium, Gel, AGM, or Lithium batteries, the BCDC1212T has an input current limited to 12Amp, ensuring the current rating of the trailer plug is not exceeded, so you don’t need to add a special high current connector, such as an Anderson plug. This DC charger uses a multi-stage charging profile so that auxiliary batteries used in trailers can be fully charged.
Charge while you drive
Before REDARC, you could only get a finite amount of use out of your trailer battery before needing to recharge from AC mains. With the BCDC1212T, the battery is recharged as you drive. This means less time and power used waiting for them to charge before you leave, and more time spent on the road without running out of battery power.
Installation tips and tricks
The BCDC1212T is fully sealed meaning it’s protected against water and dust and can be installed in the engine bay or on the trailer’s A-frame. It is an ideal solution for installation in the A-frame toolbox or nose cone of a dump trailer, or the back of a truck equipped with a liftgate. Ideally, you’d want to install it as close to the secondary battery as possible so it can overcome voltage drop due to long cable runs. REDARC also has several fuse kits and accessories to make installation easier.
