The Ironman dual battery monitor displays the voltage levels of both batteries.
Keep a closer eye on your battery with the new Ironman 4x4 dual battery monitor. The new monitor displays a digital readout for both main and Auxilary battery, it also shows a bar graph style incidator. To ensure your batteries are healthy the Ironman 4x4 monitor shows if either battery is under charged (11V) or over charged (15v). We have built in an auto dimming feature to ensure this does not bother the driver at night. The monitor can be used with dual or single battery set ups.
Can be used on dual or single 12V battery setups

Over and under voltage indicators
