Efficient Power Management for Vehicles with Dual Batteries Using Cole Hersee Battery Isolators

For vehicles with two batteries, Cole Hersee Battery Isolators ensure efficient power management by electrically preventing the higher-charged battery from draining into the lower-charged one, helping to avoid electrical system failures. These isolators allow both batteries to charge simultaneously from a single source while keeping them electrically separated. Designed for general-purpose use, Cole Hersee offers isolators rated for negative ground alternator systems with outputs ranging from 70 to 250 amps (12-36V DC).

Each isolator has a "per leg" rating, indicating the maximum current it can supply to either battery. This rating is always half the alternator's maximum output. For example, Del City Item #948051, rated at 75A, can deliver up to 37.5A per leg. Built for durability and reliable performance, Cole Hersee isolators are intended for negative ground systems and are not suitable for use with self-energizing alternators.

  • General purpose Isolators for 12-36V DC negative ground alternator systems.
  • Rated for use with systems ranging from 70 amps to 250 amps output.
  • Embedded electronic components to protect from adverse conditions.
  • Integral heat sink to provide heat dissipation.
