Buy Can Am Dual Battery Kit On the Web Today
Quick fact: 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.
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. 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 upgrades 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. You keep stock starting capacity and gain usable amp-hours for winch, lights, and audio everywhere you ride.
Why a Can-Am Dual Battery Kit Makes Sense for Your Next Ride
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
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
An isolator-managed system preserves the stock battery so cranking stays strong after long accessory use.
- 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.
- Smart energy management: No manual switches—key position controls behavior automatically.
Can-Am Dual Battery Kit: Features & Benefits
This section highlights the practical advantages of the upgrade for trail use and everyday reliability. Automatic control plus a rugged mount and sealed cells keep electronics powered while protecting the starter.
An 80A isolator ties sources Key ON and isolates the starter cell Key OFF. This automation prevents accessory draw from draining your starting source.
Rugged mounting bracket for vibration and hits
The reinforced mount holds steady across washboard and big landings. It resists loosening and fatigue so the install stays tidy and serviceable.

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 if you already own a compatible cell. Both options protect starting power and add capacity for lights/audio/recovery.
Primary 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.
- A reinforced bracket that secures the assembly against vibration and impacts.
- Documentation that guides harness routing and proper distribution termination.
| Item | Role | Benefit |
|---|---|---|
| Secondary AGM cell | Adds capacity | Starter remains ready during accessory use |
| 80A isolator relay | Manages charge and isolation | Stops accessory drain on starter |
| Model harness | Connects components | Easier installs and service access |
| Distribution block & hardware | Fused accessory feeds | Tidy fused circuits for lights/audio |
All parts suit off-road duty, with sealing where needed against dust/moisture. 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.
Prep a clear workspace and lay out the labeled parts. Mount the reinforced bracket, set the 2nd cell in place, and follow the harness leads to each terminal.
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.
Secure mounting + clean harness routing
Follow factory paths, use clips, and add abrasion sleeves at pinch points. Use the supplied hardware to make clean grounds and fused distribution points instead of daisy-chaining accessory feeds.
| Step | Action | Why it matters |
|---|---|---|
| Mount bracket | Secure to reinforced points | Handles vibration and maintains clamp load |
| Place 2nd cell | Seat and fasten with clamp | Keeps terminals safe and serviceable |
| Connect harness | Follow labeled leads and fuse points | Makes upgrades and diagnostics easier |
Most mechanically inclined owners finish this installation with basic tools. Amp-rated isolator plus proper cabling stabilize power and protect the starter on long rides.
Performance, Charging, and Long-Term Maintenance
Strong, steady power keeps your aftermarket electronics UTV setup performing under heavy load. Proper charging and routine care make that reliability repeatable 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 recommends topping between trips 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 design curbs damage over rough terrain.
| Area | Gain | What to do |
|---|---|---|
| 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. That reduces surprises and helps preserve next-morning starts on every trip.
