The REDARC BCDC1240D In-vehicle Battery Charger is a 12V 40A In-vehicle DC to DC battery charger. It is the latest variant of the award-winning BCDC Dual range and features REDARC’s Smart Start technology.

Featuring a Maximum Power Point Tracking (MPPT) solar regulator, the BCDC1240D will charge from both solar and the alternator simultaneously. 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 BCDC1240D also comes with patented charging profiles, including a lithium charging profile. The 'Dual' input range will continue to charge all other types of batteries including AGM, GEL, standard lead acid and calcium. 

As a guide, the BCDC1240D is used for battery bank sizes over 200AH. For smaller batteries of 75-200AH REDARC recommends the BCDC1225D

 

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%.*

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

The BCDC1240D has been tested in New Zealand’s unique conditions, the In-vehicle battery charger will work in the diverse weather our islands have to offer - water, dust and vibration are no match for this charger.

If you’re heading out into the wild 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 Lithium (LiFePO4) batteries
  • Suitable for use on vehicles with conventional alternator charging systems

 

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.

Redarc BCDC 1240D
Having had a REDARC BCDC 1240D installed in my Ranger for a few years now I have to say that this is one awesome bit of kit.

The unit is a compact, easy to install, set and forget unit. It is ultra reliable and ensures that your battery is always charged to its optimum level.

One of the best features of this unit is that it doubles as a MPPT solar regulator, the solar panel I am using is only good for 14 amps output according to its specifications, however the BCDC manages to pull 20A out of the solar panel without any problems.

I currently have this unit charging a 200aH Enerdrive B-Tec lithium battery.

I would not buy anything else.

BCDC1240
I have purchased cheap inferior equipment in the past and paid for it dearly, normally, when I'm in the bush. I  have recently installed the BCDC1240 and it is the standard I have come to expect from REDARC - installed it and when power was supplied it went to work maintaining  my auxiliary batteries. Another awesome product by the worlds best!!!

Best DC DC Chargers you can get
For our under bonnet Dual battery  requirement, we went with the 40A version as we setup our Caravan trailer plugs (Anderson) connection to draw off our dual Battery, this saving our starter Battery from ever going flat. the Van pulls 30Amps. So have 10 Amps left for other bits and pieces and not run the dual battery flat. Added a couple of Anderson plugs  under the bonnet also, 1 Blue for unregulated solar (connection via the BCDC charger) And 1 grey for regulated solar input direct to the battery or as a high current output, like a compressor. The 40A BCDC keeps up with the high demand we place on it day in, day out, and in all extreme conditions.
