Surprising fact: with 18 additional amp hours, long rides feel different for lights and sound. That extra capacity lets accessories run longer while your starter stays 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.
Arrives fresh, sealed AGM and fully charged and hardware sized to match your vehicle. The Can Am x3 dual battery kit setup needs no daily maintenance, and a quality maintainer is advised to limit sulfation and extend service life.
Order online for clear fitment data and quick delivery, reducing time from purchase to install. You keep stock starting capacity and gain usable amp-hours for winch, lights, and audio everywhere you ride.
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. 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
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: A second battery gives extra amp hours for high-draw gear at camp or on long rides.
- Reduced strain: Moving accessory load off the starter lowers wear on circuits/components.
- Smart energy management: No manual switches—key position controls behavior automatically.
Can Am dual battery kit Features and Benefits
Practical advantages for real trails and day-to-day reliability. The design pairs automatic energy management with a rugged mount and sealed cells to keep electronics running 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. 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/fatigue so your install stays neat and serviceable.

- Distribution hardware with fused connection 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 | Controls charge/isolation | Prevents accessory draw from draining starter |
| Model harness | Wiring link | 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. It integrates with existing charging/accessory circuits for organized, reliable routing.
Installation Made Straightforward
Install is straightforward so your rig stays trail-ready with minimal downtime.
Start with a clear workspace and the labeled parts laid out before you. Install the bracket, seat the second battery, then connect the labeled harness leads.
Simple behavior: Key ON/OFF
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.
Solid bracket placement with tidy harness routing
Use factory routing, secure with clips, and sleeve abrasion points. Use the supplied hardware to make clean grounds and fused distribution points instead of daisy-chaining accessory feeds.
| Step | What to do | Reason |
|---|---|---|
| Mount bracket | Bolt into reinforced points | Handles vibration and maintains clamp load |
| Place 2nd cell | Seat battery and clamp firmly | Protects terminals and service access |
| Connect harness | Follow labeled leads and fuse points | Makes upgrades and diagnostics easier |
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 & Long-Term Care
Steady power keeps aftermarket UTV electronics performing under heavy loads. 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
Use a good maintainer to prevent sulfation, the primary cause of capacity loss in AGM batteries. 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.
- Vibration-resistant sealed AGM construction reduces rough-terrain damage.
| Aspect | Gain | What to do |
|---|---|---|
| Performance | Stable voltage under load | Add a secondary AGM to support high-draw gear |
| Charging | Lower long-term capacity loss | Employ a quality charger/maintainer between outings |
| 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.
