Good to know: an extra 18 amp hours on a UTV can transform long-ride lighting and audio use. This added capacity powers accessories longer and keeps the starter protected.
A purpose-built 80A isolator links both batteries Key ON and isolates the starter Key OFF so accessories pull from the second battery. Its heavy-duty mount resists vibration/impacts for real off-road use.
Arrives fresh, sealed AGM and fully charged plus vehicle-matched hardware. The lift kit for Can Am defender hd10 setup needs no daily maintenance, and a quality maintainer is advised to limit sulfation and extend service life.
Shop online to confirm fitment and get fast shipping, minimizing downtime from order to install. It preserves stock starting power yet adds usable amp-hours for winches, lights, and stereo on any trail.
Top Reasons to Run a Can-Am Dual Battery Kit on Your Next Trip
When your rig needs long nights of lights and music, a dedicated secondary power source keeps the starter ready for the moment that matters. An 80A isolator ties both batteries Key ON and isolates the starter Key OFF so accessories pull from the aux cell, not the stock one.
Power accessories while protecting your stock battery
Drive light bars, audio, GPS, and heaters without draining the starter. You get steadier voltage to sensitive electronics, reducing dim and drop during load spikes.
Confident starts with stock battery starting preserved
Because the isolator protects the stock cell, your engine still cranks strong after a full night of electronics.
- Extra reserve: A second battery gives extra amp hours for high-draw gear at camp or on long rides.
- Less wear: Offloading accessories reduces stress on the starting circuit and components.
- Automatic management: No manual switching required—system behavior is automatic based on key position.
Key Features & Benefits of the Can-Am Dual Battery Kit
Here’s what the upgrade delivers for trails and daily reliability. It combines automatic management, rugged mounting, and sealed cells so electronics run without risking the starter.
With an 80 amp isolator, sources link Key ON and the starter is isolated Key OFF. That automation stops accessories from draining the starter.
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
UTV Stereo’s Platinum AGM ships fresh and fully charged. Sealed AGM construction resists spill/vibration and needs no routine maintenance.
Extra capacity over stock for lighting, audio, and gear
- Gain about 18 amp hours versus stock for longer runtime with lights and audio.
- Steadier loaded voltage preserves audio clarity and lamp brightness at idle.
- Complete kit integrates with factory wiring for a neat, durable install.
Can-Am Owners: Model Fitment and Options
Choose the right fit for your UTV with model-specific packages that match factory mounting points and wiring paths.
Can-Am Maverick X3 owners get a full 2nd battery kit that includes all wiring and hardware for a turnkey upgrade. If you’ve got an AGM already, the mount-only bracket from UTV Stereo makes for a tidy install.
Maverick X3: full second-battery kit or dual-mount bracket
Pick a complete kit for fast setup or the bracket-only path when reusing an existing cell. Either way, you get a factory-style look and secure fit.
Defender: tailored 2nd battery kit that fits the stock compartment
Built to fit the stock bay, the Defender kit preserves service access. That keeps factory clearances intact while adding reliable second battery capacity.
Already have an AGM? Choose bracket-only or wiring-only kits
Save by using a wire-and-mount package if you already have a battery. This solution delivers professional routing and solid mounting without extra parts.
Alternative Packages: DS18 bracket/wire-only and AKJ Offroad full kits
- AKJ Offroad offers another full kit option.
- DS18 offers a wire/bracket-only package and advertises free shipping on U.S. orders.
- Engineered to model geometry for factory-style, trail-secure installs.
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.
Choose a full package with a secondary agm battery or select the bracket-only route when you already have a compatible cell. Either way preserves the starter and adds usable capacity for lights, audio, and recovery tools.
Core components
- An 80 amp battery isolator relay module to manage charge flow between sources.
- Model-specific harness that reduces splices and speeds installation.
- Power distribution hardware featuring fused points for clean accessory feeds.
- Bracket, reinforced, to resist shock and vibration.
- Clear documentation to route the harness and terminate distribution points correctly.
| Item | Function | Why it matters |
|---|---|---|
| Secondary AGM cell | Adds capacity | Keeps starter ready while running accessories |
| 80A isolator relay | Manages charge and isolation | Stops accessory drain on starter |
| Model harness | Wiring link | Simplifies install 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. Integration with existing charge/accessory circuits keeps routing tidy and reliable.
Easy, Straightforward Install
Simple installation keeps you trail-ready without losing hours in the garage.
Begin with a clean workspace and lay out labeled parts. Mount the bracket, place the second cell, and route the harness to labeled terminals.
Key Position Behavior Made Simple
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.
Solid bracket placement with tidy harness routing
Use factory routing, secure with clips, and sleeve abrasion points. Use supplied hardware for clean grounds and fused distribution rather than daisy-chaining.
| Step | What to do | Why it matters |
|---|---|---|
| Mount bracket | Bolt into reinforced points | Maintains clamp load under vibration |
| Place 2nd cell | Seat battery and clamp firmly | Keeps terminals safe and serviceable |
| Connect harness | Follow labeled leads and fuse points | Makes upgrades and diagnostics easier |
Basic tools are enough for most mechanically inclined owners. Properly rated isolator and cables stabilize delivery and protect the starter on extended rides.
Performance, Charging, and Long-Term Maintenance
Steady power keeps aftermarket UTV electronics performing under heavy loads. Proper charging and routine care make that reliability repeatable season after season.
Expect steadier voltage with better performance for amps, winches, and high-output lights. The auxiliary AGM trims voltage dips on spikes, keeping sound clean and lights bright.
Use a charger/maintainer to prevent sulfation
Use a good maintainer to prevent sulfation, the primary cause of capacity loss in AGM batteries. UTV Stereo recommends topping between trips to preserve capacity and extend life.
- Key OFF isolation preserves stock battery health.
- Running engine alternator replenishes reserves for efficient recharge on long rides.
- Vibration-resistant sealed AGM construction reduces rough-terrain damage.
| Area | Benefit | Action |
|---|---|---|
| Performance | Steadier voltage under load | Add a secondary AGM to support high-draw gear |
| Charging | Less capacity loss over time | Employ a quality charger/maintainer between outings |
| Long-term care | Longer service life | Do routine maintenance charging on sealed cells |
Pro tip: Keep a suitable maintainer handy to stay topped up. This reduces surprises and preserves morning starts trip after trip.
