REDARC's BCDC Core 25A DC to DC In-Cabin Battery Charger is the next evolution of the legendary BCDC platform that has been powering off-grid adventures for over 10 years. 

The BCDC Core is the perfect DC to DC charging solution for in-cabin, canopy, or battery box setups where dust and weatherproofing isn’t required. Each BCDC Core features REDARC’s tried and tested dual input DC charging tech plus an MPPT solar regulator and Green Power Priority all in the familiar and compact BCDC form factor. These features allow the BCDC Core to efficiently charge from both the alternator and solar simultaneously, ensuring maximum charge capacity no matter the situation.

Looking for a DC-DC Charger for an under bonnet installation? The REDARC BCDC Classic range in 25amp, 40amp and 50amp models could be what you're looking for.

Max Charge Efficiency

The BCDC Core features a Maximum Power Point Tracking (MPPT) solar regulator and 'Green Power Priority'. With these features the BCDC Core will charge from both solar and the alternator simultaneously, maximising its charge rate and minimising the load on your alternator, saving fuel. 

Compact & Silent

With no loud fans or relays and a small form factor, the BCDC Core can be tucked away, leaving room in the cabin for more important things. Don't ruin the look of your interior with bulky electronics. Hide it under the rear floor, behind a side panel or under the seats and make your power set up look like it was meant to be there.  

Lithium Ready 

With chemistry specific charging profiles, including lithium the BCDC Core ensures your batteries are ready for your next adventure. The award-winning technology in the BCDC Core has been independently verified and tested to ensure battery life is maximised, charging your battery to a proven 100%.*

For most applications, the BCDC Core 25A is suitable for battery bank sizes of 60-200AH for AGM and lead acid and up to 100AH for lithium. Check the manufacturer’s data for your battery and ensure that the ‘Continuous Current Rating’ of the charger does not exceed the manufacturer’s recommended maximum charging current. For higher capacity needs of over 200AH, REDARC recommends the BCDC Core 40A. 

*Large capacity battery banks may require a few cycles to fully charge.

Backed by the Best

The BCDC Core is designed, tested and manufactured in Australia and is backed by our leading technical support and national REDNetwork certified installer network.

If you’re heading out into the bush and want to get there and back again safely – you can trust REDARC.

Bonus wiring loom - valued at $ 89.00

This wiring loom has been designed for the use with any DC Battery Charger that uses a common earth (one earth cable running from the DC Charger).

The wiring loom has been especially designed around the use with Redarc DC Battery Chargers.

Simple to fit, the loom is wired in 8mm / 8B&S cable, which matches the gauge cable used on both the 25 Amp and 40 Amp DC Charger.

The loom includes: 

- An 8mm / 8B&S Fused connection from the DC charger to alternator input power

- An 8mm / 8B&S fused connection from the DC charger to the AUX Battery feed

- A common earth connection for all negative connections (via a 8mm post)

This DC wiring loom will allow you to add your selection of cable to continue the run from the Midi Fuse bolt to feed both the alternator input and the AUX battery connection.

The recommendation:

When using a 25 Amp DC charger, it is recommended to fit 8mm/8B&S cable in order to minimize voltage drop. This cable can be purchased in any length in either a Twin core 8mm or Single core 8mm. It is important to note that when using DC cable, just as much power is transferred through the negative cable as what it is through the positive cable. It is in the opinion of Home of 12 Volt to always run a twin core cable when possible for power feeds.

When using a 40 Amp DC charger, it is recommended to fit 13.5mm/6B&S cable in order to minimize voltage drop. This cable can be purchased in any length in either a Twin Core 13.5mm or Single core 13.5mm


The DC wiring loom is available to purchase with either (Select your option)

- 2 x 40 Amp Midi Fuse fitted (DC-WL40) *Recommended for 25A Chargers

- 2 x 60 Amp Midi Fuse fitted (DC-WL60) *Recommended for 40A Chargers

The DC wiring loom components are listed below

- 2 x Positive cables with pre-crimped 6mm lugs for Midi Fuse & pre-crimped 8mm joiners for DC connection
- 2 x Midi Fuse Holders
- 2 x Midi Fuses
- 3 x Additional 8mm joiners
- 4 x Red Heatshrink sleeves

- 1 x Earth Block
- 2 x CL10-6 Copper Lugs
