25Amp In Vehicle Battery Charger

The REDARC BCDC1225D 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 BCDC1225D 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 BCDC1225D features the same patented charging profiles as it’s predecessor along with a new lithium charging profile making the unit suitable for charging AGM, Gel, Standard Lead Acid, Calcium and LiFePObatteries.

For most applications, the BCDC1225D is suitable for battery bank sizes of 75-200AH. For higher capacity needs of over 200AH, REDARC recommends the BCDC1240D.

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.
