Ironman 140 Amp Information

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.

Ironman 275 Amp Information

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.

Emergency Parallel Function: The Ironman 275 Amp Dual Battery Kit allows the user to override the automatic function and link the two batteries together. This can be done by turning the yellow knob on the unit or by pushing the override switch located in the vehicle.
