Exclusive to Portable Power Technology in the UK, the REDARC range of battery to battery chargers are designed and tested in Australia for the toughest conditions to provide easy and efficient in-vehicle charging of batteries.

The new REDARC BCDC1225D is a 12V/24V input 25A output In-vehicle Battery to Battery charger. Incorporating dual input technology the BCDC1225D will easily and efficiently charge your 12V auxiliary battery on the move from alternator and solar utilising the integrated MPPT controller.

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 short fall from the vehicle alternator.

Three models at 25A ,40A and the new 50A 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/Sealed lead acid/Calcium). The unit also now has a lithium (LiFePO4) charging profile to reliably fast 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.

Proven and Tested

Compact in size, easy to install and fully sealed – water, dust and vibration are no match for the in-vehicle battery to battery charger.
Designed to handle the roughest tracks in outback Australia and adopted by all the major UK commercial vehicle converters, the BCDC won’t let you down and is suitable for installation in harsh environments or marine applications.
