Taking Care of You and Your Vehicle

 

Duel Battery System

A dual battery system in a 4×4 is very handy, especially if you like running accessories from your 4×4 when camping and in particular if you run a compressor fridge in the back.

The idea of a dual battery system is to have all (or most) of your accessories connected to the second battery (usually a deep cycle).

As your accessories use power from the second battery the isolator prevents power from draining from your main starting battery leaving it ready for you to start your vehicle when needed. When you start your vehicle the isolator senses the charge from your alternator and links the 2 batteries together and charges them as you drive.

140 amp

The Ironman 140 Amp Dual Battery Kit allows two batteries to be charged at the same time. When the engine is started and the main battery reaches 13.4 volts, the Ironman module engages, allowing the two batteries to be charged simultaneously. When the voltage drops below 12.8 volts (e.g. the engine is stopped), the Ironman module disengages, isolating the batteries.


The Ironman dual battery monitor displays the voltage levels of both batteries. The Ironman 140 Amp Dual Battery Kit eliminates the possibility of draining the starting battery, as long as your accessories are connected to your auxiliary battery.

Motorised 275 Amp


The Ironman 275 Amp Dual Battery Kit performs an automated parallel function which allows two separate batteries to be charged as one. When the main battery reaches 13.7 volts, the Ironman 275 Amp Dual Battery Kit engages, allowing two batteries to be charged simultaneously.


When the voltage drops below 12.2 volts, the Ironman 275 Amp Dual Battery Kit disengages, isolating the batteries. This system eliminates the possibility of draining the start battery, as long as your accessories are connected to your auxiliary battery.
