$584.10 Regular price $649.00
Description

The REDARC BCDC1240D is a high-performance 12V 40A DC to DC battery charger built for Australia’s toughest conditions. Designed to charge your auxiliary battery from both solar and alternator simultaneously, it’s the perfect companion for serious 4WDers, campers, and tradies running dual battery setups.

With Green Power Priority and an integrated MPPT solar regulator, the BCDC1240D maximises solar efficiency before drawing from your vehicle — reducing strain on your alternator. Whether you’re using AGM, Gel, standard lead acid, calcium, or lithium (LiFePO4), it delivers a reliable multi-stage charge that extends battery life and keeps your gear running strong.

Fully sealed and built to last, this charger is made to withstand dust, water, heat (up to 80°C), and vibration — from desert tracks to river crossings.
