Powerline Battery Isolators


Battery Isolators - 33HD Series

The function of a battery isolator is to allow multiple batteries to be charged from a single or dual alternator system and prevent reverse drain from either battery when the vehicle is not running. HD Power Solutions offers over 100 models of multi-battery Powerline Isolators. They are among the finest isolators on the market and engineered with heat-chamber testing to handle the total isolator rating with either battery leg.

Models are available here for service to systems from 70 to 190 amps with standard negative ground.
