Why Choose a Can-Am Dual Battery Kit for Your Next Adventure
For long nights of lights and music, a dedicated auxiliary source keeps the starter ready when you need it. With an 80A isolator, Key ON combines sources; Key OFF isolates the starter so accessories draw from the auxiliary battery.
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 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: The auxiliary cell adds amp-hour reserve for high-draw gear on trail or at camp.
- Reduced strain: Accessory offload eases stress on starter circuits and components.
- Smart energy 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. Automatic control plus a rugged mount and sealed cells keep electronics powered while protecting 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.
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.

In the Box: What You Get
A clear parts list explains what’s included and how each piece protects the starter while feeding accessories.
Opt for a complete package with the secondary AGM or go bracket-only when you already have a compatible cell. 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 that reduces splices and speeds installation.
- 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.
| Item | Role | Why it matters |
|---|---|---|
| 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 | Neat fused circuits for lights and audio |
Parts are off-road ready and sealed as needed for dust/moisture resistance. It integrates with existing charging/accessory circuits for organized, reliable routing.
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 reinforced bracket, set the 2nd cell in place, and follow the harness leads to each terminal.
Simple behavior: Key ON/OFF
With the key ON, the 80A isolator links sources; key OFF keeps the starter isolated. This design ensures accessories pull from the auxiliary so the starter remains reserved after long stops.
Secure bracket placement and clean harness routing
Route the harness along factory paths, secure it with clips, and add abrasion protection at pinch points. Use the supplied hardware to make clean grounds and fused distribution points instead of daisy-chaining accessory feeds.
| 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 | Simplifies future upgrades and diagnostics |
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.
Performance, Charging, and Long-Term Maintenance
Strong, steady power keeps your aftermarket electronics UTV setup performing under heavy load. With proper charging and routine care, reliability repeats season after season.
Expect steadier voltage and improved performance for audio amps, winches, and high-output lights. A dedicated secondary agm reduces dips during spikes so sound stays clean and lamps stay bright.
Charger/Maintainer: your sulfation prevention
Regular top-offs with a quality maintainer help prevent sulfation—the main cause of capacity loss in AGM designs. 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.
- Sealed, vibration-resistant AGM design curbs damage over rough terrain.
| Area | Benefit | Action |
|---|---|---|
| Performance | Stable voltage under load | Add a secondary AGM to support high-draw gear |
| Charging | Lower long-term capacity loss | Use a quality charger/maintainer between rides |
| Long-term care | Extended service life | Pair sealed cells with routine maintenance charging |
Tip: Keep a suitable maintainer handy to stay topped up. It cuts surprises and preserves next-morning starts on every trip.
