PriorityStart! 24 Volt Promax HD

The 24-Volt H.D. version of the PriorityStart! is specifically designed for any 24-Volt battery, or 12-Volt dual batteries wired in "Series" (that is, from positive on battery 1 to negative on battery 2 -- see instructions below). The 24-Volt system works and installs just like the 12-Volt ProMax and features the same benefits! However, the disconnect threshold is factory set at 23.6 volts.

The 24-Volt H.D. application is most often seen in farming, military and many international vehicles found outside of the United States.
