Overview
REDARC's BCDC Core 40A 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 ideal for in-cabin, canopy, or battery box setups where dust and weatherproofing isn’t required. It features REDARC’s dual input DC charging technology, an MPPT solar regulator, and Green Power Priority, all in a compact form factor. This allows simultaneous charging from the alternator and solar, ensuring maximum charge capacity.
If you need an under-bonnet DC-DC charger, consider the REDARC BCDC Classic range available in 25A, 40A, and 50A models.
Max Charge Efficiency
The BCDC Core uses Maximum Power Point Tracking (MPPT) and Green Power Priority to charge efficiently from both solar and alternator simultaneously, maximizing charge rate and minimizing alternator load, saving fuel.
Compact & Silent
No loud fans or relays, and a small form factor allow the BCDC Core to be tucked away under floors, behind panels, or under seats for a clean installation.
Lithium Ready
With chemistry-specific charging profiles including lithium, the BCDC Core ensures batteries are ready for your next adventure. Independently tested technology maximizes battery life, charging up to 100%.*
Typical usage: Lead acid banks over 200Ah and lithium batteries over 100Ah. Check your battery specifications to ensure the continuous current rating does not exceed recommended limits. For smaller batteries, REDARC recommends the BCDC Core 25A.
*Large capacity battery banks may require a few cycles to fully charge.
