Our Amazon Store Reviews
“Ordered the kit, had a couple of questions about where to mount the isolator and how long the cables are. True’s support answered pretty quickly, and I got a tip that helped hide the wiring from splash damage. After using the UTV dual battery isolator for several months, it’s still solid as day one.”

What makes this UTV battery isolator different from standard ones?
When we talk about a True® dual battery isolator, what sets it apart from many other isolators on the market comes down to a few key features:
Smart Charging Technology – True isolators often have intelligent circuitry that ensures your auxiliary battery charges efficiently without overloading the starter battery. Many standard isolators just split voltage without optimizing charge.
High Current Capacity – True isolators are rated for heavy-duty use (often 140A+), which means they can handle multiple accessories like fridges, winches, lights, and inverters simultaneously. Many generic isolators are rated lower, limiting what you can run safely.
Durability & Build Quality – True isolators are designed for off-road and harsh conditions. They usually have solid connectors, robust casings, and corrosion-resistant terminals, unlike cheaper models that may fail under vibration or weather.
Voltage Sensing & Protection – True units often include voltage-sensitive relays or smart circuitry that prevent your starter battery from being drained, automatically disconnecting loads when necessary. Cheaper isolators may not protect your starting battery as effectively.
Compatibility & Easy Installation – True isolators are designed to fit popular vehicles (like Ford, Toyota, Honda, Jeep) with minimal modifications. Other brands might require custom wiring or extra components.
How does it work?
The kit uses an intelligent battery isolator with PEP® (Power Excursion Protection) technology. This ensures the main battery is prioritized for starting, while the auxiliary battery powers accessories
How do I monitor battery status?
- Optional Single Meter Dual Display (SMDD) shows real-time voltage for both batteries.
- Saves space and simplifies monitoring

Best bang for your buck out there
Due to its compact size, this battery isolator is simple to place, performs admirably, and offers you a variety of mounting alternatives. The ones I looked at were literally four and five times as much as this one and didn’t do anything more. In order to connect the batteries, it turns blue when it goes on. It operates exactly as it should when I use a trickle charger on the primary battery; it waits until that battery is fully charged before turning on and allowing the secondary battery to charge. Fantastic product at a great price.

This is functioning as planned thus far. turns on when the car is started. disconnects as soon as the voltage is low. It’s the best Teryx battery isolator I could have ever imagined.

Installing a battery isolator kit is an excellent way to stop your vehicle’s accessories, such as the stereo system, mobile and laptop chargers, LED lights, winch, air conditioning, and even refrigeration, from depleting each other’s batteries. You can extend the life of your battery and avoid being stuck forever by using a twin battery arrangement and an isolator kit.
Tom Prowers –
To separate the starting battery from the accessories battery, I added a second battery to my Teryx. After a long day of using electronics and other equipment, this dual battery isolator system will guarantee that the starting battery is fully charged and prepared to start the engine. To ensure that the accessory battery is charged while the outboard is operating, I utilized a digital volt meter to track when the isolator closed and opened. Functioned flawlessly.

Bought this to add an extra battery to my kawasaki teryx 800 le sxs. Instructions that came with it were a little vague but once i got it all hooked up it works great!!!!! Nice that it came with a volt meter so i can see it charging my starting battery and then switch over and charge my accessory battery. Dont have to worry about all my accessories killing my starting battery. And if i notice the accessory battery is running low all i have to do is start the sxs up and it will charge the battery right back up. Must have if your running lots of accessories on your side by side and dont want to run your starting battery down and be stranded.

So far so good. It passed the smoke test. Nothing burned up. Pretty easy install. Not sure about the blue light staying on quite a bit on the isolator but so far no worries. If I turn on the key and hit the head lights blue light on the isolator usually goes out.
