🚙 Why It’s Ideal for Maverick X3 & Defender
These Can-Am models are often outfitted with high-demand accessories—winches, stereos, lighting, GPS units—and this kit ensures:
- Your starter battery stays protected
- Your accessory battery powers your gear
- Both batteries charge safely and efficiently
The True® Can Am defender 2nd battery kit was designed for performance, with attention paid to every detail of installation and operation on modern stator based electrical systems. In addition, it’s optimized with True® PEP® technology for peak performance and battery quality protection.
Instead of the conventional double meters, the new True® Can Am Defender Second Battery Kit contains a distinctive lone meter with twin displays. The new meter has the same diameter as the old model, but it will have a thread depth of over one inch, requiring a little more space under the surface but allowing it to be installed in much thicker material.
Like the original meters, it is a 36mm waterproof and shockproof digital LED voltmeter that will enable you to monitor the charge status on each battery. In addition, True® has provided a complete kit.
Can Am Dual Battery Kit Wiring Diagram
The Can-Am Dual Battery Kit Wiring Diagram illustrates how to safely connect a secondary battery to your vehicle’s electrical system, ensuring reliable power for accessories without draining the main starter battery.
This setup typically includes:
- A smart battery isolator relay to manage charging between the main and auxiliary batteries.
- Heavy-gauge battery cable and ground cables for efficient current flow.
- A dual voltage gauge to monitor batteries.
The diagram shows how to route power from the alternator to both batteries, with the isolator ensuring the main battery is prioritized for starting. This configuration is ideal for powering lights, stereos, winches, or fridges on Can-Am models like the Maverick or X3.

It worked as expected. True dual battery kit never fail on me.
I order it for a set of Can-Am led lights that needed a second battery connection to avoid draining problem in my Maverick X3.

This was simple to put together, and the gauges let you know when it’s operating. Keep the directions handy because it connects a little differently than you may expect. I wish they would make the gauges the same color instead of Blue and Green. For my 2017 Can-Am Defender, I used this.

It’s a high-quality device with all of the necessary components and good instructions. So far, everything is going nicely.
Andrew Willson –
This is an easy installation even if you are not mechanics. The CanAm itself, as well as the effort necessary in wiring the batteries and fixing cable path, provide the minimum challenge.
The battery package presented its own set of diagram. The printed instructions are included and easy to understand. It was really beneficial to be able to observe the actual installation from the video.

This is the 2nd time I’ve purchased this UTV isolator; the first one gone when I sold my UTV. You NEED this dual battery isolator if you have a second battery and a lot of accessories.

This is what I put on my Can-Am Outlander 1000 XMR from 2021. In order to prevent my system from using up my primary battery while keeping the rest of the system charged, I added additional batteries and used this isolator.
This device stated it is waterproof and I put that to the test! I repeatedly immersed my bike in water while riding it, and it was fine!

No more dead battery on the trail. This UTV dual battery kit is too easy to install . My 2014 Can-Am commanders was not designed to house 2 batteries so I had to engineer placement.
