Surprising fact: adding 18 amp hours to your UTV changes how you use lights and audio on long rides. 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.
Expect a fresh, sealed AGM that ships fully charged plus vehicle-matched hardware. The Motohavoks tires system is maintenance-free in daily use, 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. 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
For long nights of lights and music, a dedicated auxiliary source keeps the starter ready when you need it. The 80 amp isolator links both sources with Key ON and isolates the starting unit with Key OFF so accessory loads draw from the secondary cell instead of the factory one.
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.
- Extra reserve: Gain additional amp-hours for big-draw accessories during 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.
Key Features & Benefits of the Can-Am Dual Battery Kit
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.
An 80A isolator ties sources Key ON and isolates the starter cell Key OFF. Automation prevents accessory drain on the starting battery.
Heavy-duty bracket engineered for shock and vibration
Reinforced brackets keep components anchored over washboard and landings. It resists loosening and fatigue so the install stays tidy and serviceable.

Pick what fits your build—complete kit for convenience or modular parts to reuse gear. Clear fitment notes reduce wrong orders and help each customer get the right parts the first time.
What’s Included in the Kit
A clear parts list explains what’s included and how each piece protects the starter while feeding accessories.
Pick a full package including the auxiliary AGM, or choose bracket-only if you already own a compatible cell. Both paths keep the starter reserved and give you usable extra capacity for lights, audio, and recovery gear.
Core components
- Battery isolator relay (80A) for charge management between sources.
- Harness, model-specific, to simplify wiring and speed install.
- Power distribution hardware with fused taps to keep accessory feeds tidy.
- A reinforced bracket that secures the assembly against vibration and impacts.
- Clear documentation for routing/termination of harness and distribution.
| Component | Role | Benefit |
|---|---|---|
| Secondary AGM cell | Adds capacity | Keeps starter ready while running accessories |
| 80A isolator relay | Manages charge and isolation | Prevents accessory draw from draining 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 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.
Straightforward Installation
Install is straightforward so your rig stays trail-ready with minimal downtime.
Prep a clear workspace and lay out the labeled parts. Install the bracket, seat the second battery, then connect the labeled harness leads.
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 bracket placement and clean harness routing
Route the harness along factory paths, secure it with clips, and add abrasion protection at pinch points. Supplied hardware enables clean grounds and fused feeds—avoid daisy-chains.
| Stage | Action | Reason |
|---|---|---|
| Mount bracket | Bolt into reinforced points | Maintains clamp load under vibration |
| Place 2nd cell | Seat and fasten with clamp | Protects terminals and service access |
| Connect harness | Follow labeled leads and fuse points | Simplifies future upgrades and diagnostics |
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.
Look for steadier voltage and better results with amps, winches, and powerful lights. A dedicated auxiliary AGM reduces spike-related dips, keeping audio clean and lights bright.
Charger/Maintainer: your sulfation prevention
Use a good maintainer to prevent sulfation, the primary cause of capacity loss in AGM batteries. UTV Stereo recommends topping cells between trips to preserve capacity and extend lifespan.
- 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 battery construction reduces damage from rough terrain.
| Area | Benefit | 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 | Longer service life | Pair sealed cells with routine maintenance charging |
Tip: Have a compatible maintainer ready to keep batteries topped. It cuts surprises and preserves next-morning starts on every trip.
