Quick fact: adding 18 amp hours to your UTV changes how you use lights and audio on long rides. 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 with hardware sized for your specific vehicle. The Can Am x3 dual battery setup needs no daily maintenance, though a charger or maintainer is recommended to prevent sulfation and extend life.
Shop online for clear fitment and fast delivery so a customer can move from order to install with minimal downtime. This smart upgrade preserves stock starting capacity while adding usable amp-hours for winches, lighting, and stereo power on every 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.
Use accessories freely and preserve your stock battery
Run light bars, audio, GPS, and cabin heat while keeping the starter untouched. You get steadier voltage to sensitive electronics, reducing dim and drop during load spikes.
Confident cranks with stock starting kept intact
An isolator-managed system preserves the stock battery so cranking stays strong after long accessory use.
- Reserve capacity: A second battery gives extra amp hours for high-draw gear at camp or on long rides.
- Reduced strain: Accessory offload eases stress on starter circuits and components.
- Automatic management: No manual switches—key position controls behavior automatically.
Key Features & Benefits of the Can-Am Dual Battery Kit
Here’s what the upgrade delivers for trails and daily reliability. It combines automatic management, rugged mounting, and sealed cells so electronics run without risking the starter.
An 80A isolator ties sources Key ON and isolates the starter cell Key OFF. That automation stops accessories from draining the starter.
Rugged mounting bracket for vibration and hits
A reinforced bracket anchors components through washboard trails and hard landings. It resists loosening and fatigue so the install stays tidy and serviceable.

What’s Included in the Kit
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 when you already have a compatible cell. Either way preserves the starter and adds usable capacity for lights, audio, and recovery tools.
Primary components
- 80 amp battery isolator relay to manage charging/isolation.
- Model-specific harness that reduces splices and speeds installation.
- Distribution hardware with fused connection points for clean accessory feeds.
- Bracket, reinforced, to resist shock and vibration.
- Clear documentation for routing/termination of harness and distribution.
| Component | Role | Benefit |
|---|---|---|
| Secondary AGM cell | Adds capacity | Starter remains ready during accessory use |
| 80A isolator relay | Manages charge and isolation | Prevents accessory draw from draining starter |
| Model harness | Connects components | 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. Integration with existing charge/accessory circuits keeps routing tidy and reliable.
Easy, Straightforward Install
A straightforward install keeps your rig trail-ready without hours in the garage.
Prep a clear workspace and lay out the labeled parts. Mount the bracket, place the second cell, and route the harness to labeled terminals.
Simple behavior: Key ON/OFF
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.
Secure mounting + clean harness routing
Follow factory paths, use clips, and add abrasion sleeves at pinch points. Use supplied hardware for clean grounds and fused distribution rather than daisy-chaining.
| Stage | What to do | Reason |
|---|---|---|
| Mount bracket | Bolt into reinforced points | Maintains clamp load under vibration |
| Place 2nd cell | Seat and fasten with clamp | Keeps terminals safe and serviceable |
| Connect harness | Follow labeled leads and fuse points | Simplifies future upgrades and diagnostics |
Most mechanically inclined owners finish this installation with basic tools. Properly rated isolator and cables stabilize delivery and protect the starter on extended 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.
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.
Prevent sulfation with a charger/maintainer
Use a good maintainer to prevent sulfation, the primary cause of capacity loss in AGM batteries. 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 battery construction reduces damage from rough terrain.
| Area | Gain | What to do |
|---|---|---|
| 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 | Extended service life | Pair sealed cells with routine maintenance charging |
Pro 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.
