Complete Kit
The Boss 4WD Complete DIY Dual Battery Kit is back! Our highly sought after kits include everything you need to install a dual battery system in your 4WD apart from the tools, labour and battery. Each kit includes one of our seriously strong auxiliary battery trays, a Thunder 20 Amp DC to DC Charger for newer vehicles, and a wiring kit that has been specced up to handle whatever you throw at it. We don't mess around when it comes to keeping your beer cold - our philosophy is to over-spec the cabling, ensuring that you're not going to be sipping on warm beer in the middle of the desert due to a faulty or poorly designed battery system.
We supply the best dual battery kits there are! Read below for more information on each component, and see why we make such bold claims:
Thunder 20 Amp DC-DC Charger
Thunder are well known for providing great value 4WD accessories, including this DC to DC Charging System. The DC to DC Charger is used in place of a battery isolator on vehicles that have an alternator controlled by the ECU. The charger negates the drop or decline in output from the alternator, ensuring your auxiliary battery remains charged, and your beer icy cold.
Thunder's solution to this style of isolator is an 8 Stage, 20 Amp self-diagnosing charging system, that even incorporates a 300W MPPT Solar Regulator. This system is simple to install, and sports an easy to read LED display. Being housed in an aluminium casing helps dissipate the heat, ensuring the components stay cool and delivering maximum performance.
Wiring Kit
Did we go a bit overboard when we designed our wiring kits? Some may say so, but we think they're spot on. By over-speccing the cable we supply (and use for our own vehicles) we can ensure that the cable will never "bottle-neck" the system, nor will it be the cause of a battery system failing.
We supply 13mm² (6B&S) Twin Sheathed Battery Starter cable in our DC-DC kits, which is over twice the thickness of the cable supplied in many kits. Both positive leads are fused by a 50 Amp Maxi-Blade Fuse to protect the system. The gradual breakdown of cables due to heat and corrugated roads will also pose less of a problem.
We also supply heavy duty brass battery terminals, full metal crimp lugs, heat shrink, split corrugated conduit, and even cable ties. This means you'll be able to have the neatest, best performing battery system around. We even supply a basic wiring diagram to help you with the install. What this all means for you is cold beer
Battery Tray
An Auxiliary Battery Tray is a key component of a Dual Battery System, and will allow you to fit second (or sometimes even a third) battery under the bonnet of your 4WD.
This high quality steel - not plastic - battery tray is manufactured right here in Australia, and is not just another cheap imported copy. Each tray is designed specifically to suit a particular vehicle application, taking into consideration factors such as heat, strength and maximum battery sizes.
Our battery trays come as a complete kit along with fitting instructions, all required hardware, and a battery hold down clamp. We are even happy to supply a battery system wiring diagram free of charge if you purchase a battery tray or kit from us - simply send us your email address, and we will email you the pdf.
Check out these features, and see why we're proud to offer the best battery trays on the market:
