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.
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.
Comes as a sealed AGM, shipped fully charged with hardware sized for your specific vehicle. The Polaris ranger snow plows kit runs maintenance-free day to day, 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. It preserves stock starting power yet adds usable amp-hours for winches, lights, and stereo on any trail.
Why Choose a Can-Am Dual Battery Kit for Your Next Adventure
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.
Run accessories without draining 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 with stock battery starting preserved
Because the isolator protects the stock cell, your engine still cranks strong after a full night of electronics.
- Extra reserve: The auxiliary cell adds amp-hour reserve for high-draw gear on trail or at camp.
- Reduced strain: 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. Automatic control plus a rugged mount and sealed cells keep electronics powered while protecting the starter.
An 80A isolator ties sources Key ON and isolates the starter cell Key OFF. This automation prevents accessory draw from draining your starting source.
Rugged mounting bracket for vibration and hits
A reinforced bracket anchors components through washboard trails and hard landings. It resists loosening/fatigue so your install stays neat and serviceable.
UTV Stereo Platinum Series AGM: sealed, maintenance-free, long-lasting
Platinum Series AGM comes fresh and pre-charged. Sealed AGM means spill resistance, vibration toughness, and no routine maintenance.
Adds extra amp hours vs stock for lights, audio, and accessories
- Approximately 18 extra amp-hours compared to stock for longer accessory use.
- Cleaner under-load voltage preserves sound quality and lamp brightness at idle.
- The complete battery kit integrates with the factory system for a neat, durable install.
Fitment & Options for Can-Am Models
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: complete 2nd battery kit and dual battery mount
Go complete for quick setup, or bracket-only to reuse an existing cell. Both approaches aim for a factory look and secure fit.
Defender: tailored 2nd battery kit that fits the stock compartment
Defender kits fit stock space and preserve access for service. That keeps factory clearances intact while adding reliable second battery capacity.
Bracket-only and wire kit options if you already own an AGM battery
Save by using a wire-and-mount package if you already have a battery. This solution delivers professional routing and solid mounting without extra parts.
Alternatives: DS18 wire/bracket-only and AKJ Offroad solutions
- Explore AKJ Offroad for another full package option.
- DS18 has wire/bracket-only options and promotes free shipping in the U.S..
- Each product is engineered around model geometry so the install looks factory and stays secure on rough trails.
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.
In the Box: What You Get
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’ve already got a compatible battery. 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.
- Model-specific harness to limit splices and speed installs.
- Power 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 | Role | Why it matters |
|---|---|---|
| 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 | Easier installs and service access |
| Distribution block & hardware | Fused accessory feeds | Neat fused circuits for lights and 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.
Installation Made Straightforward
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 Key ON/Key OFF behavior
With the key ON, the 80A isolator links sources; key OFF keeps the starter isolated. The design routes accessory load to the aux battery, preserving the starter after extended stops.
Secure mounting + 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.
| Step | What to do | Reason |
|---|---|---|
| Mount bracket | Bolt into reinforced points | Handles vibration and maintains clamp load |
| Place 2nd cell | Seat and fasten with clamp | Keeps terminals safe and serviceable |
| Connect harness | Connect labeled leads/fuse points | Simplifies future upgrades and diagnostics |
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 & Long-Term Care
Steady power keeps aftermarket UTV electronics performing under heavy loads. With proper charging and routine care, reliability repeats season after season.
Look for steadier voltage and better results with amps, winches, and powerful lights. A dedicated secondary agm reduces dips during spikes so sound stays clean and lamps stay bright.
Prevent sulfation with a charger/maintainer
Regular top-offs with a quality maintainer help prevent sulfation—the main cause of capacity loss in AGM designs. 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.
- 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 | Stable voltage under load | Add a secondary AGM to support high-draw gear |
| 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 suitable maintainer handy to stay topped up. It cuts surprises and preserves next-morning starts on every trip.
