REDARC’s range of In-vehicle Dual Battery Chargers are designed, built and tested in Australia for our unique conditions to make sure they won’t let you down.

With features like fully sealed construction and fan-free cooling - water, dust and vibration are no match for the In-vehicle Dual Battery Charger... you can be assured they can handle the roughest tracks in outback Australia and the deepest water crossings at Cape York.

REDARC’s knowledge of Australian conditions is engineered into every unit. All models operate up to a market-leading 80°C meaning they are going to work in even the most extreme heat of the Simpson Desert. A higher operating temperature and compact in size also allows for flexible installation options, from the engine bay to inside a van or camper trailer.

Look at all the benefits… Multi-stage charging saves you money by maximising battery life, increase run time of loads like fridges and lights, allows for flexible installation in 12 or 24 volt vehicles and overcomes voltage drop caused by long cable runs.

12 volt auxiliary battery chargers: There are two output current options to choose from - 6 and 20 amps - they charge AGM, gel, calcium content, VRLA and standard lead acid batteries while driving. The IGN-model is suitable for vehicles with an ECU-controlled, variable voltage alternator.

12 volt dual input auxiliary battery chargers: The next-generation 25, 40 and 50 amp models with fully integrated MPPT solar regulators are able to charge common lead acid auxiliary batteries as well as lithium iron phosphate batteries (LiFeP04). They charge from solar and DC inputs simultaneously, with built in ‘Green Power Priority’ they will select solar first, meaning less load on the alternator. They also suit standard and variable voltage/smart alternators.

24 volt auxiliary battery chargers: To meet the demands of 24 volt auxiliary battery charging, a range of 24 volt, 20 amp chargers are available. They feature a fully integrated MPPT solar regulator. The BCDC2420 charges AGM, gel, calcium content, VRLA and standard lead acid batteries. The LFP2420 and LFP2420-LV are designed to charge Lithium Iron Phosphate (LiFeP04) batteries. The LV model features a lower voltage setting so it can operate with variable voltage alternators.
