Buy Can Am Dual Battery Kit Right Now Online
Quick fact: an extra 18 amp hours on a UTV can transform long-ride lighting and audio use. That extra capacity lets accessories run longer while your starter stays protected.
Engineered with an 80 amp isolator, it combines sources when the key is on and protects the starter when the key is off, feeding accessories from the auxiliary cell. The rugged mount fights vibration and shock for authentic off-road duty.
Comes as a sealed AGM, shipped fully charged with hardware sized for your specific vehicle. The CanAm defender lift 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 a Can-Am Dual Battery Kit Makes Sense for Your Next Ride
If you run lights and audio late, a second power source keeps the starter prepared. 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.
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 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: Gain additional amp-hours for big-draw accessories during long rides.
- Less wear: Offloading accessories reduces stress on the starting circuit and components.
- Automatic 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.
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
Reinforced brackets keep components anchored over washboard and landings. Resistance to loosening and fatigue keeps installs tidy and easy to service.

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.
Choose a full package with a secondary agm battery or select the bracket-only route when you already have a compatible cell. Either way preserves the starter and adds usable capacity for lights, audio, and recovery tools.
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 featuring fused 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 | Role | Benefit |
|---|---|---|
| Secondary AGM cell | Provides extra amp hours | Keeps starter ready while running accessories |
| 80A isolator relay | Manages charge and 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. It integrates with existing charging/accessory circuits for organized, reliable routing.
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 design ensures accessories pull from the auxiliary so the starter remains reserved after long stops.
Solid bracket placement with tidy 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 | What to do | Why it matters |
|---|---|---|
| Mount bracket | Secure to reinforced points | Handles vibration and maintains clamp load |
| Place 2nd cell | Seat battery and clamp firmly | Keeps terminals safe and serviceable |
| Connect harness | Connect labeled leads/fuse points | Simplifies future upgrades and diagnostics |
Most mechanically inclined owners finish this installation with basic tools. Amp-rated isolator plus proper cabling stabilize power and protect the starter on long rides.
Performance, Charging, and Long-Term Maintenance
Steady power keeps aftermarket UTV electronics performing under heavy loads. With proper charging and routine care, reliability repeats season after season.
Expect steadier voltage with better performance for amps, winches, and high-output lights. A dedicated auxiliary AGM reduces spike-related dips, keeping audio 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 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.
- While running, the alternator replenishes reserves so long rides restore charge efficiently.
- Sealed, vibration-resistant agm battery construction reduces damage from rough terrain.
| Aspect | Gain | What to do |
|---|---|---|
| Performance | Steadier voltage under load | Add a secondary AGM to support high-draw gear |
| 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 |
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.
