True® Smart Dual Battery Kit for Can-Am Maverick, Commander, and Defender
The True® can am defender dual battery kit is the ultimate power management solution for riders who demand reliable electrical performance on every adventure. Designed specifically for Can-Am UTVs and side-by-sides, this can am defender dual battery kit allows you to safely add a second battery to power accessories without risking your primary starting battery. Whether you are running winches, light bars, GPS units, radios, sound systems, air compressors, or other high-draw accessories, the True® dual battery system delivers dependable auxiliary power when you need it most.
At the heart of the system is the premium True® Battery Isolator, engineered to automatically manage charging between the primary and auxiliary batteries. The isolator intelligently charges both batteries while the engine is running and separates them when the vehicle is off, helping prevent accidental battery drain. This means you can confidently operate your accessories for extended periods while ensuring your Can-Am still has enough power to start every time.

Why Choose the True Brand System?
Smart Voltage Sensing: The isolator automatically monitors the primary battery. It only begins charging the secondary battery once the starting battery reaches $13.3\text{V}$, ensuring your engine always has the cranking power it needs.
Total Isolation: When the engine is off, the Can Am X3 battery kit automatically separates the batteries. This allows you to run your accessories until the secondary battery is empty without ever touching the charge of your starting battery.
Fully Submersible: Designed for the toughest UTAH trails, the True® brand isolator is fully waterproof and vibration-resistant, making it perfect for mud-runners and creek crossings.

🚙 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.

“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.”

Frequently Asked Questions!
Does installing this can am x3 dual battery kit void my factory warranty?
No. Because this is a non-intrusive “straight-to-battery” connection, you aren’t tapping into the fuse box or cutting factory wires. It functions as an independent add-on, keeping your factory electrical system intact.
Why does the LED stay on after the engine is turned off?
Do I need to run a ground wire from the auxiliary battery to the main battery?
Can I mount it without drilling holes?
The kit works with most 12V battery types (AGM, gel, standard lead-acid). It is not recommended for lithium batteries unless specified.
Is the isolator waterproof/durable?
Yes, the isolator features an IP65 rating for water, dust, and vibration resistance, making it ideal for harsh automotive, marine, or off-road environments.
What is P.E.P.® (Proprietary Efficiency Programming)?
- P.E.P.® is TrueAm’s smart logic that optimizes battery protection and charging efficiency.
- It ensures the isolator only connects when safe and beneficial for both batteries
Does it regulate charging amps?
- No, the SBI doesn’t regulate amperage. That’s handled by your alternator and voltage regulator.
- The SBI simply controls when the second battery is connected based on voltage thresholds.
Can I manually override or shut it off?
- The male connector underneath can be wired for remote shutoff.
- Inline switches are optional but not required—SBI handles disconnection automatically.
How do I monitor battery status?
- Optional Single Meter Dual Display (SMDD) shows real-time voltage for both batteries.
- Saves space and simplifies monitoring
Is can am x3 dual battery kit compatible with all batteries?
It’s designed specifically for Chevy Silverado and GMC Sierra trucks, but can also be adapted for other GM vehicles with similar 12V systems

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.

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.

Directions were ok. Could be a little clearer.
Working great so far. Easy to install IF you have slight electrical skills.
