Surprising fact: an extra 18 amp hours on a UTV can transform long-ride lighting and audio use. This added capacity powers accessories longer and keeps the starter 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. A heavy-duty mount resists vibration and impacts for true off-road service.
Comes as a sealed AGM, shipped fully charged and hardware sized to match your vehicle. The 2022 Honda rancher 420 radiator relocation kit system is maintenance-free in daily use, but using a charger/maintainer helps prevent sulfation and lengthen life.
Shop online to confirm fitment and get fast shipping, minimizing downtime from order to install. You keep stock starting capacity and gain usable amp-hours for winch, lights, and audio everywhere you ride.
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. 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.
Power accessories while protecting your stock battery
Power more accessories like light bars, sound systems, GPS, and in-cab heaters without depleting your starting source. Accessory power remains steady for sensitive gear, cutting dimming and dips during spikes.
Confident starts thanks to preserved stock starting power
The isolator-driven system automatically prioritizes preserving stock battery so your machine cranks strong after a long night with electronics running.
- Reserve capacity: The auxiliary cell adds amp-hour reserve for high-draw gear on trail or at camp.
- Less wear: Offloading accessories reduces stress on the starting circuit and components.
- Automatic management: No manual switching required—system behavior is automatic based on key position.
Can-Am Dual Battery Kit: Features & Benefits
Here’s what the upgrade delivers for trails and daily 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.
Heavy-duty mounting bracket built for vibration and impacts
Reinforced brackets keep components anchored over washboard and landings. It resists loosening and fatigue so the install stays tidy and serviceable.
UTV Stereo Platinum Series AGM: sealed design, maintenance-free, durable

- Approximately 18 extra amp-hours compared to stock for longer accessory use.
- Steadier loaded voltage preserves audio clarity and lamp brightness at idle.
- Complete kit integrates with factory wiring for a neat, durable install.
Can-Am Owners: Model Fitment and Options
Pick model-specific packages that match factory mounts and wiring paths.
Can-Am Maverick X3 owners can choose a full second-battery kit with all wiring/hardware for turnkey install. If you already own an AGM, the mount-only option from UTV Stereo provides a neat bracket for a tidy install.
Maverick X3: full second-battery kit or dual-mount bracket
Choose the full kit for speed or go bracket-only if you’re reusing a battery. Both choices target a factory look and secure fit.
Defender Fit: second-battery kit sized for the stock compartment
The Defender kit is built to fit the stock space and preserve service access. Factory clearances remain intact while adding reliable auxiliary capacity.
Already have an AGM? Choose bracket-only or wiring-only kits
Save money with a wire-and-mount package when you have a spare battery. It delivers pro routing and solid mounting without unnecessary parts.
Other Options: DS18 bracket/wire packages and AKJ Offroad kits
- Check AKJ Offroad for a complete package alternative.
- DS18 has wire/bracket-only options and promotes free shipping in the U.S..
- All are engineered to model geometry for factory-look installs that hold up off-road.
Choose the path that matches your build: full kit for convenience, or modular parts to integrate gear you already own. Clear fitment notes reduce wrong orders and help each customer get the right parts the first time.
What’s Included in the Kit
Here’s what you receive and how it protects the starter yet feeds accessories.
Opt for a complete package with the secondary AGM or go bracket-only when you already have a compatible cell. Both options protect starting power and add capacity for lights/audio/recovery.
Primary components
- 80 amp battery isolator relay to manage charging/isolation.
- Model-specific harness to limit splices and speed installs.
- Distribution hardware with fused connection points for clean accessory feeds.
- Reinforced bracket to secure components against vibration/impacts.
- Documentation that guides harness routing and proper distribution termination.
| Component | Role | Why it matters |
|---|---|---|
| Secondary AGM cell | Adds capacity | Starter remains ready during accessory use |
| 80A isolator relay | Controls charge/isolation | Stops accessory drain on starter |
| Model harness | Wiring link | Simplifies install and service access |
| Distribution block & hardware | Clean accessory feeds | Tidy fused circuits for lights/audio |
All parts are selected for off-road use and sealed where needed to resist dust and moisture. It integrates with existing charging/accessory circuits for organized, reliable routing.
Easy, Straightforward Install
Simple installation keeps you trail-ready without losing hours in the garage.
Prep a clear workspace and lay out the labeled parts. Install the bracket, seat the second battery, then connect the labeled harness leads.
Simple Key ON/Key OFF behavior
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.
Secure mounting + 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 | Makes upgrades and diagnostics easier |
Basic tools are enough for most mechanically inclined owners. The amp-rated isolator and proper cables keep power delivery steady and protect starting batteries during long rides.
Performance, Charging, 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.
Expect steadier voltage with better performance for 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
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.
- Key OFF isolation preserves stock battery health.
- While running, the alternator replenishes reserves so long rides restore charge efficiently.
- Sealed, vibration-resistant AGM design curbs damage over 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 suitable maintainer handy to stay topped up. It cuts surprises and preserves next-morning starts on every trip.
