INTRODUCTION
Congratulations on purchasing the most robust, vibration resistant, battery monitoring device on the
market. It is designed for easy installation, even with little or no electrical experience
The
Digital Power Manager w/ Jump Start P/N 40121
is a weather-proof battery isolator; battery
combiner and jump start system for your vehicle. It provides Main start-battery charging priority
protection along with automatically combining two batteries for large electrical loads up to 500 amps
momentarily: such as winches, auxiliary lights, and other large electrical accessories. The DPM also
automatically controls when the auxiliary battery will be charged based on the charge level of the Main
battery. This means the Main battery voltage must reach 12.6 volts before the Auxiliary battery will be
allowed to charge.
The
DPM w/Jump Start P/N 40121
kit only contains the wires and terminals needed to install this kit
between two 12 volt batteries. The DPM is designed to pass 280 amps of current continuously or 500
amps momentarily
during a “Jump Start”. All wires included in this kit can be seen in the
