Buy Can Am Dual Battery Kit Right Now Online
Good to know: adding 18 amp hours to your UTV changes how you use lights and audio on long rides. More capacity means longer accessory runtime while safeguarding the starter.
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. The rugged mount fights vibration and shock for authentic off-road duty.
Comes as a sealed AGM, shipped fully charged plus vehicle-matched hardware. The all things ATV setup needs no daily maintenance, 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. This smart upgrade preserves stock starting capacity while adding usable amp-hours for winches, lighting, and stereo power on every 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.
Run accessories without draining your stock battery
Run light bars, audio, GPS, and cabin heat while keeping the starter untouched. Accessory power remains steady for sensitive gear, cutting dimming and dips during spikes.
Confident starts thanks to preserved stock starting power
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: Accessory offload eases stress on starter circuits 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
This section highlights the practical advantages of the upgrade for trail use and everyday reliability. The design pairs automatic energy management with a rugged mount and sealed cells to keep electronics running without risking the starter.
With an 80 amp isolator, sources link Key ON and the starter is isolated Key OFF. This automation prevents accessory draw from draining your starting source.
Rugged mounting bracket for vibration and hits
Reinforced brackets keep components anchored over washboard and landings. It resists loosening and fatigue so the install stays tidy and serviceable.

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
- Battery isolator relay (80A) for charge management between sources.
- Model-specific harness to limit splices and speed installs.
- Distribution hardware featuring fused points for clean accessory feeds.
- A reinforced bracket that secures the assembly against vibration and impacts.
- Documentation that guides harness routing and proper distribution termination.
| Item | Function | Why it matters |
|---|---|---|
| Secondary AGM cell | Adds capacity | Starter remains ready during accessory use |
| 80A isolator relay | Manages charge and isolation | Prevents accessory draw from draining starter |
| Model harness | Connects components | Easier installs and service access |
| Distribution block & hardware | Clean accessory feeds | Tidy fused circuits for lights/audio |
All parts suit off-road duty, with sealing where needed against dust/moisture. Integration with existing charge/accessory circuits keeps routing tidy and reliable.
Straightforward Installation
Simple installation keeps you trail-ready without losing hours in the garage.
Prep a clear workspace and lay out the 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.
Secure mounting + clean harness routing
Route the harness along factory paths, secure it with clips, and add abrasion protection at pinch points. Supplied hardware enables clean grounds and fused feeds—avoid daisy-chains.
| Stage | What to do | Reason |
|---|---|---|
| Mount bracket | Bolt into reinforced points | Handles vibration and maintains clamp load |
| Place 2nd cell | Seat and fasten with clamp | Keeps terminals safe and serviceable |
| Connect harness | Connect labeled leads/fuse points | Simplifies future upgrades and diagnostics |
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.
Performance, Charging & Long-Term Care
Steady power keeps aftermarket UTV electronics performing under heavy loads. Routine care and proper charging make performance repeatable each season.
Look for steadier voltage and better results with amps, winches, and powerful lights. A dedicated auxiliary AGM reduces spike-related dips, keeping audio clean and lights 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.
- Key OFF isolation preserves stock battery health.
- While running, the alternator replenishes reserves so long rides restore charge efficiently.
- Vibration-resistant sealed AGM construction reduces rough-terrain damage.
| Area | Gain | What to do |
|---|---|---|
| Performance | Stable 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 |
Tip: Keep a suitable maintainer handy to stay topped up. It cuts surprises and preserves next-morning starts on every trip.
