Ironman 4x4 DB270 Dual Battery 275AMP Relay

The Ironman 270 Amp Dual Battery Kit allows two batteries to be charged at the same time. When the engine is started, the IRONMAN 4X4 module engages, allowing the two batteries to be charged simultaneously.

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.When the voltage drops below 12.8 volts (e.g. the engine is stopped), the Ironman module disengages, isolating the batteries.
