Product Description


The REDARC BCDC1240D In-vehicle Battery Charger is the next generation in REDARC's DC to DC charging technology, with additional features that make it the most advanced dual battery charger on the market.

  • Featuring a Maximum Power Point Tracking (MPPT) solar regulator, the BCDC1240D will charge from both solar and the alternator simultaneously. And, with built-in 'Green Power Priority' it will select solar charging first, meaning less load on the alternator.
  • Suitable for 12 or 24-volt vehicle systems, the unit will also work with either standard or variable/smart alternators.
  • The BCDC1240D features the same patented charging profiles as its predecessor along with a new lithium charging profile making the unit suitable for charging AGM, Gel, Standard Lead Acid, Calcium and LiFePO4 batteries.
  • As a guide, the BCDC1240D is used for battery bank sizes over 200AH. For smaller applications, the BCDC1225D is suitable for battery bank sizes of 75-200AH.

Proven and Tested
The award-winning technology in the BCDC has been independently verified and tested to ensure battery life is maximised, charging your battery to a proven 100%. Built in Australia and tested for our unique conditions, the DC to DC battery charger will work in the extreme heat of the Simpson Desert, up to 80°C and can handle deep water crossings at Cape York – water, dust and vibration are no match for this charger. If you’re heading out into the bush and want to get there and back again safely – you can trust REDARC.
