Description

 The unit will work to connect different types of batteries and keep them separated when there is no charging voltage available so that they do not “balance” and reduce each other efficiency like if they are paralleled without smart management.

Got a winch or plow you want to be serious about using but don’t want to worry about over working your alternator or discharging your primary battery?  Then the TRUE® Medium Dual Battery Kit is exactly what you need.

Want to run those off road lights and high amp stereo without worrying about getting stranded? Then the TRUE® Medium Dual Battery Kit will handle the batteries for you!

As with all the TRUE products it features easy installation requiring no connection to the alternator or ignition.

All the TRUE kits include proprietary built cables that use special adhesive lined shrink tube to provide a fully waterproof corrosion -proof connection between cable and lug. The adhesive also provides the connection extra strength eliminating the possibility of the lug pulling off even in high stress and/or vibration applications. A TRUE exclusive!

Kit Inclusions

  • 10 ft Red #6 cable with attached lug ends to fit the TRUE Isolator
  • 2 ft Black #6 cable with attached end lugs for 2nd battery ground

Features

  • Automatic control: No manual switching needed—charging is intelligently managed.

  • Voltage-triggered isolation: Protects the primary battery by disconnecting it when voltage drops, preventing accidental drain.

  • Reliable starting power: Guarantees your vehicle always has enough charge to start, even if the secondary battery is heavily used.

  • Versatile use: Ideal for trucks, Jeeps, RVs, boats, and off-road vehicles where dual battery setups are common.

  • Complete kit contents: Includes heavy-duty cables, lugs, shrink tubing, and zip ties for a professional, under-the-hood installation.

    Fixed my truck power problems. For the air bag system, I put two ahm batteries. There is no flickering of the electricity when compressors operate. My batteries are constantly fully charged thanks to this battery isolator.
