DIY - Dual Battery Kit - Redarc Bcdc1225D - Colorado - Dmax

A complete pre wired under bonnet dual battery charger kit for the Isuzu Dmax 2012 - 2019 and Holden Colorado from 10/2015 on

Using the renowned Australian made Redarc bcdc1225D charger and solar controller with Anderson plug to accept solar directly. The kit comes with the Redarc charger pre wired with soldered and heat shrunk connections, no joins required. Once you mount your choice of aux battery and battery tray under the bonnet, this kit is all that’s required to have a quality dual battery system ready to wire up any accessories you may want to run from it.

The Dmax uses a variable voltage (smart alternator) so included in this kit is a plug in fuse holder to plug into the fuse box under the bonnet to gain an ignition source for the bcdc charger. Detailed digital instructions will be emailed to you to show how this is done. No soldering or joins are required this is a plug and play kit with all wiring already done and all joins already made.

7m accessory harness to run to the rear of the vehicle and mount a socket housing. Your choice of any sockets (Cig, USB, Engel, Volt meter or Single Anderson with flip up cover) they can be customised to suit your needs. Please select your preference at checkout.

Also Available using the Redarc 1240D (40amp) and 1250D (50amp) chargers. We recommend using the 1225D (25amp) model when using lead based batteries under the bonnet such as Lead Acid Deep Cycle or AGM as most of these batteries have a max charge current 30 amps. However if using Lithium batteries the 1240D or 1250D is now available in our kits.
