The REDARC LFP1240 is a two stage 40 Amp 12V DC to DC battery charger with MPPT Solar regulator to give you extra charge from Solar system for a 12V Battery system for Lithium LiFePo4 Batteries. It can deliver sufficient current to charge a battery to achieve the optimum charge for your 4WD, Car, Truck, Bus, Caravan, Motorhome or Boat.

The REDARC LFP1240 is a 12 Volt 40 Amp In-vehicle DC to DC charger designed to keep your auxiliary battery charged whilst driving or with portable solar panels when you’re parked. The system charges your auxiliary battery to their optimum levels, using multi-stage DC DC charging.

The REDARC LFP1240 is a two stage 12 Volt 40 Amp DC to DC charger that operates with an input of between 9 and 32V.

The input voltage of the REDARC LFP1240 can be above, below or equal to the output voltage making it ideal for charging an auxiliary 12V battery where the distance from the main battery may cause a significant voltage drop.

The wide operating voltage range provides a simple solution to charging trailer mounted batteries.

The REDARC LFP1240 is a 12 Volt 40 Amp In-vehicle DC to DC battery charger designed to keep your battery charged whilst driving. Featuring multi stage battery charging, the system charges your auxiliary battery from your vehicle to a proven 100%.

The BCDC charger will work from a wide operating range (9 – 32V) giving the option of charging from only 12V vehicle systems.

By providing a unique charging profile to each specific battery type, the smart charger is able to achieve and maintain 100% charge for your auxiliary battery. You can charge your auxiliary battery no matter what your battery is. The REDARC LFP1240 is a 12 volt 40 Amp In-Vehicle Battery Charger designed to specifically charge your Lithium Iron Phosphate (LiFeP04) batteries to their optimal level, regardless of their size.

Charging Lithium Batteries

Lithium Iron Phosphate auxiliary batteries are becoming more popular in recreational and industrial applications due to their improved storage capacity relative to size and weight. They are perfect for recreational vehicle power systems. However they require specific charging conditions in order to operate correctly and the battery itself must have cell balancing and an in-built battery management system. REDARC have considered this and designed a charging profile to complement the in-built battery systems.

Proven and Tested

Compact in size, easy to install and fully sealed - water, dust and vibration are no match for the in-vehicle DC DC charger. It can handle the roughest tracks in outback Australia and even deep water crossings at Cape York. The BCDC DC to DC battery charger is suitable for installation in harsh environments or marine applications.

With an ever increasing number of electrical accessories and devices being used when travelling around Australia, along with more complex vehicle electrical systems than seen in years gone by, having the right DC battery charger has never been more important.

Designed, built and tested in Australia for our unique conditions, the BCDC in-vehicle DC to DC charger won’t let you down.
