Order Can Am Dual Battery Kit Right Now Online
Quick fact: with 18 additional amp hours, long rides feel different for lights and sound. 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. Its heavy-duty mount resists vibration/impacts for real off-road use.
Arrives fresh, sealed AGM and fully charged with hardware sized for your specific vehicle. The commander doors system is maintenance-free in daily use, but using a charger/maintainer helps prevent sulfation and lengthen life.
Shop online for clear fitment and fast delivery so a customer can move from order to install with minimal downtime. 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
For long nights of lights and music, a dedicated auxiliary source keeps the starter ready when you need it. 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
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 starts thanks to preserved stock starting power
The isolator-driven system automatically prioritizes preserving stock battery so your machine cranks strong after a long night with electronics running.
- 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.
- Automatic management: No manual switching required—system behavior is automatic based on key position.
Can Am dual battery kit Features and Benefits
This section highlights the practical advantages of the upgrade for trail use and everyday 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. That automation stops accessories from draining the starter.
Rugged mounting bracket for vibration and hits
Reinforced brackets keep components anchored over washboard and landings. Resistance to loosening and fatigue keeps installs tidy and easy to service.

Primary components
- An 80 amp battery isolator relay module to manage charge flow between sources.
- Harness, model-specific, to simplify wiring and speed install.
- Distribution hardware with fused taps to keep accessory feeds tidy.
- A reinforced bracket that secures the assembly against vibration and impacts.
- Clear documentation to route the harness and terminate distribution points correctly.
| Component | Function | Benefit |
|---|---|---|
| Secondary AGM cell | Adds capacity | Keeps starter ready while running accessories |
| 80A isolator relay | Controls charge/isolation | Stops accessory drain on starter |
| Model harness | Wiring link | Simplifies install and service access |
| Distribution block & hardware | Clean accessory feeds | Neat fused circuits for lights and audio |
All parts are selected for off-road use and sealed where needed to resist dust and moisture. It integrates with existing charging/accessory circuits for organized, reliable routing.
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 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. The design routes accessory load to the aux battery, preserving the starter after extended stops.
Secure mounting + 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 | Why it matters |
|---|---|---|
| Mount bracket | Secure to reinforced points | Handles vibration and maintains clamp load |
| Place 2nd cell | Seat and fasten with clamp | Protects terminals and service access |
| Connect harness | Connect labeled leads/fuse points | Makes upgrades and diagnostics easier |
Basic tools are enough for most mechanically inclined owners. Properly rated isolator and cables stabilize delivery and protect the starter on extended rides.
Performance, Charging & Long-Term Care
Robust, steady power sustains aftermarket electronics under load. With proper charging and routine care, reliability repeats season after season.
Expect steadier voltage with better performance for amps, winches, and high-output lights. The auxiliary AGM trims voltage dips on spikes, keeping sound clean and lights bright.
Use a charger/maintainer to prevent sulfation
Regular charging with a quality maintainer prevents sulfation, which is the leading cause of capacity loss in agm battery 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.
- When running, the alternator replenishes reserves for efficient recovery on long rides.
- Sealed, vibration-resistant AGM design curbs damage over rough terrain.
| Area | Gain | Action |
|---|---|---|
| Performance | Stable 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: Keep a compatible maintainer on hand so your batteries stay topped off. That reduces surprises and helps preserve next-morning starts on every trip.
