Surprising 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 with hardware sized for your specific vehicle. The UTV windshields and accessories setup needs no daily maintenance, but using a charger/maintainer helps prevent sulfation and lengthen life.
Order online for clear fitment data and quick delivery, reducing time from purchase to install. It preserves stock starting power yet adds usable amp-hours for winches, lights, and stereo on any trail.
Why a Can-Am Dual Battery Kit Makes Sense for Your Next Ride
When your rig needs long nights of lights and music, a dedicated secondary power source keeps the starter ready for the moment that matters. 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. 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
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: Offloading accessories reduces stress on the starting circuit and components.
- Automatic 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.
The 80 amp battery isolator links both power sources when the key is on and isolates the starter cell when the key is off. Automation prevents accessory drain on the starting battery.
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.

| Item | Function | Why it matters |
|---|---|---|
| Secondary AGM cell | Provides extra amp hours | Starter remains ready during accessory use |
| 80A isolator relay | Controls charge/isolation | Stops accessory drain on starter |
| Model harness | Connects components | Simplifies install 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. The complete package integrates with existing charge and accessory circuits so routing stays organized and reliable.
Easy, Straightforward Install
A straightforward install keeps your rig trail-ready without hours in the garage.
Start with a clear workspace and the labeled parts laid out before you. Mount the reinforced bracket, set the 2nd cell in place, and follow the harness leads to each terminal.
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.
Solid bracket placement with tidy harness routing
Use factory routing, secure with clips, and sleeve abrasion points. Supplied hardware enables clean grounds and fused feeds—avoid daisy-chains.
| Step | Action | Why it matters |
|---|---|---|
| Mount bracket | Bolt into reinforced points | Handles vibration and maintains clamp load |
| Place 2nd cell | Seat and fasten with clamp | Protects terminals and service access |

Basic tools are enough for most mechanically inclined owners. Properly rated isolator and cables stabilize delivery and protect the starter on extended rides.
Charging, Performance, and Long-Term Maintenance
Strong, steady power keeps your aftermarket electronics UTV setup performing under heavy load. Routine care and proper charging make performance repeatable each season.
Expect steadier voltage and improved performance for audio amps, winches, and high-output lights. The auxiliary AGM trims voltage dips on spikes, keeping sound clean and lights bright.
Prevent sulfation with a charger/maintainer
Regular charging with a quality maintainer prevents sulfation, which is the leading cause of capacity loss in agm battery designs. UTV Stereo recommends topping cells between trips to preserve capacity and extend lifespan.
- Stock battery health is preserved by isolating starter power Key OFF.
- When running, the alternator replenishes reserves for efficient recovery on long rides.
- Vibration-resistant sealed AGM construction reduces rough-terrain damage.
| Area | Benefit | Action |
|---|---|---|
| Performance | Steadier voltage under load | Use a new secondary agm to support high-draw accessories |
| Charging | Less capacity loss over time | Employ a quality charger/maintainer between outings |
| Long-term care | Extended service life | Pair sealed cells with routine maintenance charging |
Pro tip: Have a compatible maintainer ready to keep batteries topped. It cuts surprises and preserves next-morning starts on every trip.
