True® 12v Isolator Switch


Looking for a secondary battery for your car or truck? This kit may be for you! It’s all new transparent case makes the glowing LED light inside much easier to see when the unit is active. Plus, with the help of any TRUE 12v Isolator switch, there is no need to mess with connections to the existing wiring of your ignition or alternator since all the switching is done within the unit itself, automatically.



SKU: SBICK Category:


This 9th generation 12v voltage sensitive relay is a superior product that uses a very unique designed and programmed SBI (PEP) when it comes to dealing with the stator charging mechanism.

A TRUE exclusive!

Here are some of its advantages over 1st generation 12 volt battery kill switch:

  1. It is assembled in America and delivers through first class mail.
  2. It has an advanced specific internal programming for maximum efficiency with automotive stators. (PEP)
  3. Its new case was introduced last April 2019 specifically designed for automotive application.
  4. It has a superior cable construction with 100% waterproof shrink tube.
  5. It offers extra flex cables for easy routing.
  6. It assures correct cable ends to custom fit isolator studs.
  7. The new smart 12v isolator switch can be left suspended in-line, as long as it is mounted with provided 3M Dual Lock™, or hard mounted with any provided screws.
  8. It is compatible with all battery types like dry cell, flooded lead acid, AGM, and any hybrid types available.

With its upgraded features, the TRUE Smart 12v isolator switch is specifically designed and programmed for automotive and marine application, plus it is now American made.  This new voltage sensitive relay kit does not only provide the same application but it also showcases enhanced performance and longer lifespan.


An important note from the designer:

“The TRUE 12v battery isolator switch is the 9th generation I have designed. The first-generation products which I have designed before I figured the proper programming include the QUAD BOSS/AOPEC/Keyline units.

Together with PEP (Propriety Efficiency Programming), the all new TRUE isolator kits have added lots of upgrade which includes the case design, circuit board design, and the type of cables that should be used in order to avoid insulation and terminal failures from possible corrosion.

 Overall, its main goal is to provide stable and easy installation. The construction of the actual 12v dual battery isolator case has been exclusively redesigned for automotive application which then allows a hassle-free and versatile installation. There are possible cable access slots that need to be “knocked-out” because it may cause a breach in the seal protecting the circuit board, which is why the front mounted studs are there to eliminate unnecessary holes.

Now, we made sure to move all our production process as possible to America. These improvements made huge impacts that are essential for the benefit of all because we only aim to provide the best and most efficient products that fit the standards and demands of a vehicle’s owner.”
