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 LiFePO₄batteries.

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.

Features

Separate DC and solar charging inputs
Maximises the performance and life of your auxiliary battery
Simultaneous DC and solar charging with Green Power Priority
Suits 12V/24V standard and variable voltage/smart alternators
Suitable for AGM, GEL, standard lead acid, calcium and LiFePO₄batteries

Mounting Brackets

In addition to the use of quality fuse kits, REDARC offer a range of vehicle-specific mounting brackets for our BCDC DC-DC Charger range. The 304 stainless steel bracket allows installation into the front of the vehicle for cooler airflow, ensuring optimal performance. They have been designed to fit existing mounting points in the vehicle. Click here to view the range

The REDARC BCDC1225D is an essential part of a power management system for a successful big lap around Australia

Living on the road requires some sort of power management system to keep the beers cold, shower running and all gadgets charged. To maximize the time you can stay off the grid, a well-designed power management system containing quality equipment such as a good DC-DC charger is essential. I decided on the REDARC BCDC1225D as it allows me to charge the batteries to the full 100%. It also allows you to connect it to the alternator and solar panel simultaneously and the device will select solar power above the alternator through the Green Power Priority. Being built in Australia, you can be convinced it will handle the harsh Australian conditions.

Redarc 1225D makes travelling oz a breeze

We recently installed the BCDC1225D into our camper trailer. It is an awesome little unit that will fit in almost anywhere you want it to and a relatively easy install. Having the camper battery so far from the alternator/starter battery is not an issue now as the 1225D boosts the amps while we are driving. We were amazed at how much more charge was going into the battery while driving, arriving with a fully charged battery nearly every time even after only short drives. We were also able to remove the crappy regulator we had on our cheap ebay solar panels as the unit has a solar input as well. This also makes a huge difference to how much charge we're able to get out of our solar panels.
We recently went to Moreton Island and stayed 6 nights with average weather, only getting limited solar in and not driving the trailer. We managed to keep the batteries at an acceptable level off one solar panel which we have never been able to do for that length of time before installing the 1225D.
We knew the 1225D would make a difference to our ability to camp remote for longer periods and look after our batteries but it has definitely exceeded expectations.

Reliability!!!

Having used the BCDC1225D for nearly a year now and over 20,000kms of travelling accross the Simpson Desert, Tanami, Gibb River Road and trips down to Melbourne from Rockhampton, all i can say is it hasn't missed a beat. I dont run a traditional dual battery system. I have an Arkpac in the back that is kept charged. I run an 80lt fridge and a 12V oven off this and have never struggled for consistent power.
Like all the redarc products ive had, they have worked floorlessly for their designed purpose.

Perfect solution for a dual (or triple) battery setup

When upgrading the dual battery setup in my Land Cruiser, I wanted something that would charge the deep cycle auxiliary battery properly and maximise its lifespan. The BCDC1225D was the perfect solution. Mounted behind the grille, it doesn't take up any valuable under bonnet space. It does a great job of charging the battery from via the alternator and the dual input capability means I could set it up for solar input as well.

Installation and wiring was a breeze, and the inbuilt LEDs always let me know what's going on with the unit.

I always try to buy Australian-made stuff when I can, and previous experience with Redarc's products mean I have enormous faith it its reliability and durability.

Starting the car with a flat battery

I flattened my main battery (My fault) Thought the system would allow to start off the Aux battery but would not.
How can I start the car from the Aux battery?
Can you use jumper leads from Aux to Main? Not game to try with everything else wired up.
Jumped from another car to the main battery and OK.
System works very well with fridge and solar.

Re: Starting the car with a flat battery

Hello,

Thank you for the information.

The BCDC1225D by itself will not allow you to jump start from the auxiliary battery. To add this feature you can setup the “Ultimate Dual Battery System”.

This would require the addition of an SBI12 (https://www.redarc.com.au/smart-start-sbi-12v-100a).

The wiring diagram for the “Ultimate Dual Battery System” can be found (https://www.redarc.com.au/bcdc-dual-with-jump-start-feature-the-ultimate-battery-setup).

With this system in place you can push a button on the dash to “link” the two batteries together to jump start yourself without even lifting the bonnet.

You can jump start yourself using jumper leads from the auxiliary battery. This is only recommended when the auxiliary battery has a CCA rating (is designed to start a vehicle).

For any further assistance please contact REDARC's Tech Support Team on 08 8322 4848.

Terrific

Great unit and excellent advice over phone if needed - highly recomend using midi fuses to avoid issues years later with melting fuse holders
