The genuine accessory dual battery system for the Mazda BT-50 mounts the auxilliary battery in the tray and uses a Redarc solenoid in the engine bay for charging managment. The only thing worse than a warm beer is a car that won’t start. So having a deap-cycle battery nearby makes sense. The vehicle’s starting battery and its wiring remain largely unmodified for starting and powering the vehicle and its equipment (such as radios and interior lights), while the second battery happily powers the fridge when the vehicle is parked.Ī FRIDGE can drain a lot of power. In most dual-battery installations, the second battery’s task is to power the accessories (such as fridges), and it’s for this reason that a deep-cycle or dual-purpose battery is often installed. You should also regularly inspect the area for cracks or loosening.ĭamage of this type, usually resulting from cheap, poor quality products have wrecked many outback treks. Fasteners must be adequately sized and have large washers to spread the load across the panel work (such as an inner guard). No vehicle will endure a 15kg battery hanging from an inner mudguard with two small bolts or screws. No matter what, batteries hate heat, so batteries should be installed as far away as possible from hot engine components preferably on the cold side of the engine, opposite the exhaust. The fitment of an accessory battery tray can often be achieved by a competent handyman, although vehicle components – such as a power steering reservoir or an air-conditioner pipe – may require tweaking or relocation to provide space for a second battery tray. This means you need to pay extra attention to the wiring and battery type chosen. However, many vehicles – especially more recent models – don’t have spare room in the engine bay, so the second battery must be located elsewhere in the vehicle, such as in or under a load tray or in the passenger compartment.

This ensures you should never have a drained start battery again.
When the whole system drops to 12.7 volts the solenoid opens and isolates the start battery from the auxiliary battery. Once the start battery reaches 13.2 volts, the solenoid automatically connects the auxiliary battery to the charging system. The Redarc SBI12 primarily monitors the main start battery voltage. The solenoids are recognized throughout Australia for reliability & simplicity in 4WD and commercial grade applications, this is the reason why Off Road Downunder is proud to have Redarc Isolators as part of our product range.
