Buy Can Am Dual Battery Kit Online Today
Surprising fact: adding 18 amp hours to your UTV changes how you use lights and audio on long rides. 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.
Comes as a sealed AGM, shipped fully charged plus vehicle-matched hardware. The UTV aftermarket accessories system is maintenance-free in daily use, 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.
Top Reasons to Run a Can-Am Dual Battery Kit on Your Next Trip
If you run lights and audio late, a second power source keeps the starter prepared. 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.
Power accessories while protecting your stock battery
Run light bars, audio, GPS, and cabin heat while keeping the starter untouched. The accessory supply supplies steady voltage for sensitive electronics, reducing dimming and voltage dips when loads spike.
Confident starts thanks to preserved stock starting power
An isolator-managed system preserves the stock battery so cranking stays strong after long accessory use.
- Reserve capacity: Gain additional amp-hours for big-draw accessories during long rides.
- Less wear: Moving accessory load off the starter lowers wear on circuits/components.
- Smart energy management: Automatic behavior via key position; no manual switch needed.
Can-Am Dual Battery Kit: Features & Benefits
Practical advantages for real trails and day-to-day 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 bracket engineered for shock and vibration
A reinforced bracket anchors components through washboard trails and hard landings. It resists loosening/fatigue so your install stays neat and serviceable.

Kit Contents
Here’s what you receive and how it protects the starter yet feeds accessories.
Choose a full package with a secondary agm battery or select the bracket-only route 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.
Core components
- 80 amp battery isolator relay to manage charging/isolation.
- Model-specific harness to limit splices and speed installs.
- Power distribution hardware with fused taps to keep accessory feeds tidy.
- Reinforced bracket to secure components against vibration/impacts.
- Documentation that guides harness routing and proper distribution termination.
| Component | Function | Benefit |
|---|---|---|
| Secondary AGM cell | Provides extra amp hours | Starter remains ready during accessory use |
| 80A isolator relay | Manages charge and isolation | Stops accessory drain on starter |
| Model harness | Wiring link | Easier installs and service access |
| Distribution block & hardware | Fused accessory feeds | Tidy fused circuits for lights/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.
Installation Made Straightforward
A straightforward install keeps your rig trail-ready without hours in the garage.
Prep a clear workspace and lay out the labeled parts. Install the bracket, seat the second battery, then connect the labeled harness leads.
Simple Key ON/Key OFF behavior
Key ON links sources via 80A isolator; key OFF isolates the starter. This isolator design allows isolate new accessory loads so your starter stays reserved after long stops.
Secure bracket placement and clean harness routing
Follow factory paths, use clips, and add abrasion sleeves at pinch points. Supplied hardware enables clean grounds and fused feeds—avoid daisy-chains.
| Step | What to do | Reason |
|---|---|---|
| Mount bracket | Secure to reinforced points | Handles vibration and maintains clamp load |
| Place 2nd cell | Seat battery and clamp firmly | Protects terminals and service access |
| Connect harness | Follow labeled leads and fuse points | Simplifies future upgrades and diagnostics |
Basic tools are enough for most mechanically inclined owners. The amp-rated isolator and proper cables keep power delivery steady and protect starting batteries during long rides.
Performance, Charging, and Long-Term Maintenance
Robust, steady power sustains aftermarket electronics under load. With proper charging and routine care, reliability repeats season after season.
Look for steadier voltage and better results with amps, winches, and powerful lights. A dedicated secondary agm reduces dips during spikes so sound stays clean and lamps stay bright.
Use a charger/maintainer to prevent sulfation
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.
- The system preserves stock battery health by isolating starting power when the key is off.
- Running engine alternator replenishes reserves for efficient recharge on long rides.
- Sealed, vibration-resistant agm battery construction reduces damage from rough terrain.
| Area | Gain | Action |
|---|---|---|
| Performance | Steadier voltage under load | Use a new secondary agm to support high-draw accessories |
| Charging | Lower long-term capacity loss | Employ a quality charger/maintainer between outings |
| 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.
