Buy Can Am Dual Battery Kit Right Now Online
Quick fact: with 18 additional amp hours, long rides feel different for lights and sound. More capacity means longer accessory runtime while safeguarding the starter.
A purpose-built 80A isolator links both batteries Key ON and isolates the starter Key OFF so accessories pull from the second battery. The rugged mount fights vibration and shock for authentic off-road duty.
Arrives fresh, sealed AGM and fully charged plus vehicle-matched hardware. The Can-Am snow plow system is maintenance-free in daily use, and a quality maintainer is advised to limit sulfation and extend service life.
Shop online for clear fitment and fast delivery so a customer can move from order to install with minimal downtime. This smart upgrade preserves stock starting capacity while adding usable amp-hours for winches, lighting, and stereo power on every trail.
Why Choose a Can-Am Dual Battery Kit for Your Next Adventure
If you run lights and audio late, a second power source keeps the starter prepared. 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.
Use accessories freely and preserve your stock battery
Power more accessories like light bars, sound systems, GPS, and in-cab heaters without depleting your starting source. 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.
- Reserve capacity: A second battery gives extra amp hours for high-draw gear at camp or on long rides.
- Less wear: Moving accessory load off the starter lowers wear on circuits/components.
- Automatic management: Automatic behavior via key position; no manual switch needed.
Can-Am Dual Battery Kit: Features & 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.
An 80A isolator ties sources Key ON and isolates the starter cell Key OFF. Automation prevents accessory drain on the starting battery.
Heavy-duty bracket engineered for shock and vibration
Reinforced brackets keep components anchored over washboard and landings. It resists loosening and fatigue so the install stays tidy and serviceable.
UTV Stereo Platinum Series AGM: sealed design, maintenance-free, durable
Platinum Series AGM comes fresh and pre-charged. Sealed AGM construction resists spill/vibration and needs no routine maintenance.
Adds extra amp hours vs stock for lights, audio, and accessories
- Gain about 18 amp hours versus stock for longer runtime with lights and audio.
- Cleaner under-load voltage preserves sound quality and lamp brightness at idle.
- The complete battery kit integrates with the factory system for a neat, durable install.
Fitment & Options for Can-Am Models
Select the kit that matches factory mounts and wiring for your model.
Maverick X3 owners can opt for a full second-battery kit with wiring/hardware for a quick upgrade. If you’ve got an AGM already, the mount-only bracket from UTV Stereo makes for a tidy install.
Maverick X3: complete 2nd battery kit and dual battery mount
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 Fit: second-battery kit sized for the stock compartment
Defender kits fit stock space and preserve access for service. Factory clearances remain intact while adding reliable auxiliary 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. You get clean routing and solid mounting without buying extras.
Alternatives: DS18 wire/bracket-only and AKJ Offroad solutions
- AKJ Offroad offers another full kit option.
- DS18 has wire/bracket-only options and promotes free shipping in the U.S..
- Engineered to model geometry for factory-style, trail-secure installs.
Pick what fits your build—complete kit for convenience or modular parts to reuse gear. Clear fitment notes reduce wrong orders and help each customer get the right parts the first time.
In the Box: What You Get
A solid parts list shows exactly what arrives with your purchase and how each piece protects starting power while feeding accessories.
Opt for a complete package with the secondary AGM or go bracket-only when you already have a compatible cell. Both paths keep the starter reserved and give you usable extra capacity for lights, audio, and recovery gear.
Primary components
- An 80 amp battery isolator relay module to manage charge flow between sources.
- Harness, model-specific, to simplify wiring and speed install.
- Power distribution hardware with fused connection points for clean accessory feeds.
- Bracket, reinforced, to resist shock and vibration.
- Clear documentation for routing/termination of harness and distribution.
| Item | Function | Benefit |
|---|---|---|
| Secondary AGM cell | Adds capacity | Keeps starter ready while running accessories |
| 80A isolator relay | Controls charge/isolation | Prevents accessory draw from draining starter |
| Model harness | Wiring link | Simplifies install and service access |
| Distribution block & hardware | Clean accessory feeds | Neat fused circuits for lights and audio |
Parts are off-road ready and sealed as needed for dust/moisture resistance. The complete package integrates with existing charge and accessory circuits so routing stays organized and reliable.
Straightforward Installation
Install is straightforward so your rig stays trail-ready with minimal downtime.
Start with a clear workspace and the labeled parts laid out before you. Install the bracket, seat the second battery, then connect the labeled harness leads.
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. This design ensures accessories pull from the auxiliary so the starter remains reserved after long stops.
Solid bracket placement with tidy 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 | Action | Reason |
|---|---|---|
| Mount bracket | Secure to reinforced points | Maintains clamp load under vibration |
| Place 2nd cell | Seat and fasten with clamp | Keeps terminals safe and serviceable |
| Connect harness | Connect labeled leads/fuse points | Makes upgrades and diagnostics easier |
Most mechanically inclined owners finish this installation 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. 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. A dedicated secondary agm reduces dips during spikes so sound stays clean and lamps stay bright.
Prevent sulfation with a charger/maintainer
Regular top-offs with a quality maintainer help prevent sulfation—the main cause of capacity loss in AGM designs. 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.
- Sealed, vibration-resistant agm battery construction reduces damage from rough terrain.
| Aspect | Benefit | 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 | Pair sealed cells with routine maintenance charging |
Pro tip: Keep a compatible maintainer on hand so your batteries stay topped off. This reduces surprises and preserves morning starts trip after trip.
