The new “Dual” version of the highly acclaimed Redarc BCDC range of battery to battery chargers provides simultaneous charging of your auxiliary battery from DC and solar with a suitable PV panel connected. Green power priority ensures that power generated from solar is used first before supplementing any shortfall from the vehicle alternator.

Two new models at 25A and 40A now replace the previous BCDC varients making selection of the correct charger incredibly simple. The BCDC Dual can be used with both 12V and 24V conventional AND smart alternators (EU5/EU6) and is capable to efficiently and safely charge all common lead acid battery chemistries (AGM/SLA/Calcium). The unit also now has a lithium (LiFePO4) charging profile to easily charge a 12V lithium auxiliary battery.

The BCDC battery to battery charger range features a Maximum Power Point Tracking (MPPT) solar regulator, extracting the maximum amount of power from 12V solar panels to charge the auxiliary battery, even during low light conditions, when you’re parked.
