Buy Can Am Dual Battery Kit On the Web Today
Surprising fact: with 18 additional amp hours, long rides feel different for lights and sound. This added capacity powers accessories longer and keeps the starter protected.
A purpose-built 80A isolator links both batteries Key ON and isolates the starter Key OFF so accessories pull from the second battery. A heavy-duty mount resists vibration and impacts for true off-road service.
Expect a fresh, sealed AGM that ships fully charged plus vehicle-matched hardware. The efx Motoslayer kit runs maintenance-free day to day, 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.
Top Reasons to Run a Can-Am Dual Battery Kit on Your Next Trip
For long nights of lights and music, a dedicated auxiliary source keeps the starter ready when you need it. With an 80A isolator, Key ON combines sources; Key OFF isolates the starter so accessories draw from the auxiliary battery.
Power accessories while protecting your stock battery
Run light bars, audio, GPS, and cabin heat while keeping the starter untouched. Accessory power remains steady for sensitive gear, cutting dimming and dips during spikes.
Confident starts with stock battery starting preserved
An isolator-managed system preserves the stock battery so cranking stays strong after long accessory use.
- Extra reserve: The auxiliary cell adds amp-hour reserve for high-draw gear on trail or at camp.
- Reduced strain: Accessory offload eases stress on starter circuits and components.
- Automatic management: No manual switches—key position controls behavior automatically.
Can-Am Dual Battery Kit: Features & 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.
With an 80 amp isolator, sources link Key ON and the starter is isolated Key OFF. That automation stops accessories from draining the starter.
Heavy-duty bracket engineered for shock and vibration
Reinforced brackets keep components anchored over washboard and landings. It resists loosening/fatigue so your install stays neat and serviceable.

Kit Contents
Here’s what you receive and how it protects the starter yet feeds accessories.
Pick a full package including the auxiliary AGM, or choose bracket-only if you already own a compatible cell. Both options protect starting power and add capacity for lights/audio/recovery.
Primary components
- Battery isolator relay (80A) for charge management between sources.
- Model-specific harness that reduces splices and speeds installation.
- Distribution hardware with fused taps to keep accessory feeds tidy.
- Bracket, reinforced, to resist shock and vibration.
- 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 | Manages charge and isolation | Prevents accessory draw from draining starter |
| Model harness | Connects components | Simplifies install and service access |
| Distribution block & hardware | Fused accessory feeds | Tidy fused circuits for lights/audio |
Parts are off-road ready and sealed as needed for dust/moisture resistance. The complete package integrates with existing charge and accessory circuits so routing stays organized and reliable.
Easy, Straightforward Install
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. Mount the bracket, place the second cell, and route the harness to labeled terminals.
Simple Key ON/Key OFF behavior
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 bracket placement and clean harness routing
Follow factory paths, use clips, and add abrasion sleeves at pinch points. Use the supplied hardware to make clean grounds and fused distribution points instead of daisy-chaining accessory feeds.
| Step | What to do | Why it matters |
|---|---|---|
| Mount bracket | Bolt into reinforced points | Maintains clamp load under vibration |
| Place 2nd cell | Seat battery and clamp firmly | Protects terminals and service access |
| Connect harness | Follow labeled leads and 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 & Long-Term Care
Strong, steady power keeps your aftermarket electronics UTV setup performing under heavy load. Routine care and proper charging make performance repeatable each season.
Expect steadier voltage and improved performance for audio amps, winches, and high-output lights. A dedicated secondary agm reduces dips during spikes so sound stays clean and lamps stay 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 between trips 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.
| Aspect | Gain | Action |
|---|---|---|
| Performance | Stable voltage under load | Use a new secondary agm to support high-draw accessories |
| Charging | Less capacity loss over time | Use a quality charger/maintainer between rides |
| Long-term care | Extended service life | Do routine maintenance charging on sealed cells |
Pro tip: Keep a compatible maintainer on hand so your batteries stay topped off. This reduces surprises and preserves morning starts trip after trip.
