Quick fact: adding 18 amp hours to your UTV changes how you use lights and audio on long rides. That extra capacity lets accessories run longer while your starter stays protected.
This purpose-built upgrade uses an 80 amp isolator so, with the key on, both sources share power, and with the key off, the starting unit is safe while accessories draw from the second battery. A heavy-duty mount resists vibration and impacts for true off-road service.
Expect a fresh, sealed AGM that ships fully charged plus vehicle-matched hardware. The parts of a 4 wheeler kit runs maintenance-free day to day, but using a charger/maintainer helps prevent sulfation and lengthen life.
Shop online to confirm fitment and get fast shipping, minimizing downtime from order to install. You keep stock starting capacity and gain usable amp-hours for winch, lights, and audio everywhere you ride.
Why a Can-Am Dual Battery Kit Makes Sense for Your Next Ride
For long nights of lights and music, a dedicated auxiliary source keeps the starter ready when you need it. The 80 amp isolator links both sources with Key ON and isolates the starting unit with Key OFF so accessory loads draw from the secondary cell instead of the factory one.

Use accessories freely and preserve your stock battery
Drive light bars, audio, GPS, and heaters without draining the starter. Accessory power remains steady for sensitive gear, cutting dimming and dips during spikes.
Confident cranks with stock starting kept intact
Because the isolator protects the stock cell, your engine still cranks strong after a full night of electronics.
- Extra reserve: Gain additional amp-hours for big-draw accessories during long rides.
- Less wear: Accessory offload eases stress on starter circuits and components.
- Smart energy management: No manual switches—key position controls behavior automatically.
Can Am dual battery kit Features and Benefits
This section highlights the practical advantages of the upgrade for trail use and everyday reliability. It combines automatic management, rugged mounting, and sealed cells so electronics run without risking the starter.
The 80 amp battery isolator links both power sources when the key is on and isolates the starter cell when the key is off. This automation prevents accessory draw from draining your starting source.
Heavy-duty mounting bracket built for vibration and impacts
A reinforced bracket anchors components through washboard trails and hard landings. It resists loosening and fatigue so the install stays tidy and serviceable.
UTV Stereo Platinum Series AGM: sealed, maintenance-free, long-lasting
Platinum Series AGM comes fresh and pre-charged. Sealed AGM construction resists spill/vibration and needs no routine maintenance.

- Approximately 18 extra amp-hours compared to stock for longer accessory use.
- Cleaner voltage under load helps preserve sound quality and lamp brightness at idle.
- Complete kit integrates with factory wiring for a neat, durable install.
Can-Am Owners: Model Fitment and Options
Pick model-specific packages that match factory mounts and wiring paths.
Maverick X3 owners can choose a full second-battery kit with all wiring/hardware for turnkey install. If you already own an AGM, the mount-only option from UTV Stereo provides a neat bracket for a tidy install.
Maverick X3 Options: complete kit or bracket-only
Choose the full kit for speed or go bracket-only if you’re reusing a battery. Both choices target a factory look and secure fit.
Defender: tailored 2nd battery kit that fits the stock compartment
The Defender kit is built to fit the stock space and preserve service access. Factory clearances remain intact while adding reliable auxiliary capacity.
Bracket-only and wiring kits for owners with an AGM
Save by using a wire-and-mount package if you already have a battery. You get clean routing and solid mounting without buying extras.
Other Options: DS18 bracket/wire packages and AKJ Offroad kits
- Check AKJ Offroad for a complete package alternative.
- DS18 has wire/bracket-only options and promotes free shipping in the U.S..
- Each product is engineered around model geometry so the install looks factory and stays secure on rough trails.
Choose the path that matches your build: full kit for convenience, or modular parts to integrate gear you already own. Clear fitment guidance cuts wrong orders and gets you the right parts first try.
Kit Contents
A clear parts list explains what’s included and how each piece protects the starter while feeding accessories.
Pick a full package including the auxiliary AGM, or choose bracket-only if you’ve already got a compatible battery. Both options protect starting power and add capacity for lights/audio/recovery.
Primary components
- 80 amp battery isolator relay to manage charging/isolation.
- Model-specific harness that reduces splices and speeds installation.
- Power distribution hardware with fused taps to keep accessory feeds tidy.
- Reinforced bracket to secure components against vibration/impacts.
- Clear documentation to route the harness and terminate distribution points correctly.
| Component | Role | Benefit |
|---|---|---|
| Secondary AGM cell | Adds capacity | Starter remains ready during accessory use |
| 80A isolator relay | Controls charge/isolation | Prevents accessory draw from draining starter |
| Model harness | Connects components | Easier installs and service access |
| Distribution block & hardware | Clean accessory feeds | Neat fused circuits for lights and audio |
All parts are selected for off-road use and sealed where needed to resist dust and moisture. It integrates with existing charging/accessory circuits for organized, reliable routing.
Easy, Straightforward Install
Install is straightforward so your rig stays trail-ready with minimal downtime.
Prep a clear workspace and lay out the labeled parts. Install the bracket, seat the second battery, then connect the labeled harness leads.
Simple behavior: Key ON/OFF
The 80 amp isolator links both sources when the key is on and lets the starting cell remain battery isolated when the key is off. The design routes accessory load to the aux battery, preserving the starter after extended stops.
Secure mounting + clean harness routing
Route the harness along factory paths, secure it with clips, and add abrasion protection at pinch points. Use supplied hardware for clean grounds and fused distribution rather than daisy-chaining.
| Step | What to do | Why it matters |
|---|---|---|
| Mount bracket | Secure to reinforced points | Handles vibration and maintains clamp load |
| Place 2nd cell | Seat battery and clamp firmly | Keeps terminals safe and serviceable |
| Connect harness | Connect labeled leads/fuse points | Makes upgrades and diagnostics easier |
Most DIYers can complete the install with basic tools. The amp-rated isolator and proper cables keep power delivery steady and protect starting batteries during long rides.
Charging, Performance, and Long-Term Maintenance
Robust, steady power sustains aftermarket electronics under load. Routine care and proper charging make performance repeatable each season.
Expect steadier voltage and improved performance for audio amps, winches, and high-output lights. A dedicated auxiliary AGM reduces spike-related dips, keeping audio clean and lights bright.
Charger/Maintainer: your sulfation prevention
Use a good maintainer to prevent sulfation, the primary cause of capacity loss in AGM batteries. UTV Stereo advises between-trip top-offs to preserve capacity and extend life.
- Key OFF isolation preserves stock battery health.
- When running, the alternator replenishes reserves for efficient recovery on long rides.
- Vibration-resistant sealed AGM construction reduces rough-terrain damage.
| Aspect | Gain | Action |
|---|---|---|
| Performance | Steadier voltage under load | Use a new secondary agm to support high-draw accessories |
| Charging | Less capacity loss over time | Use a quality charger/maintainer between rides |
| Long-term care | Longer service life | Do routine maintenance charging on sealed cells |
Tip: Have a compatible maintainer ready to keep batteries topped. It cuts surprises and preserves next-morning starts on every trip.
