Good to know: an extra 18 amp hours on a UTV can transform long-ride lighting and audio use. 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. The rugged mount fights vibration and shock for authentic off-road duty.
Arrives fresh, sealed AGM and fully charged with hardware sized for your specific vehicle. The Can-Am maverick x3 glass windshield with wiper kit runs maintenance-free day to day, but using a charger/maintainer helps prevent sulfation and lengthen 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
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
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
The isolator-driven system automatically prioritizes preserving stock battery so your machine cranks strong after a long night with electronics running.
- Extra reserve: A second battery gives extra amp hours for high-draw gear at camp or on long rides.
- Less wear: Moving accessory load off the starter lowers wear on circuits/components.
- Smart energy management: Automatic behavior via key position; no manual switch needed.
Can-Am Dual Battery Kit: Features & Benefits
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. Automation prevents accessory drain on the starting battery.
Heavy-duty mounting bracket built for vibration and impacts
Reinforced brackets keep components anchored over washboard and landings. It resists loosening/fatigue so your install stays neat and serviceable.
UTV Stereo Platinum AGM: sealed, low-maintenance, long-life
UTV Stereo’s Platinum AGM ships fresh and fully charged. Sealed AGM means spill resistance, vibration toughness, and no routine maintenance.
Extra capacity over stock for lighting, audio, and gear
- About +18 amp-hours vs stock for longer light/audio runtime.
- 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.
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’ve got an AGM already, the mount-only bracket from UTV Stereo makes for a tidy install.
Maverick X3: full second-battery kit or dual-mount bracket
Go complete for quick setup, or bracket-only to reuse an existing cell. Either way, you get a factory-style look and secure fit.
Defender Fit: second-battery kit sized for 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 money with a wire-and-mount package when you have a spare battery. It delivers pro routing and solid mounting without unnecessary parts.
Alternative Packages: DS18 bracket/wire-only and AKJ Offroad full kits
- Check AKJ Offroad for a complete package alternative.
- 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.
Select a complete kit for convenience or modular parts to integrate existing gear. Clear fitment notes reduce wrong orders and help each customer get the right parts the first time.
In the Box: What You Get
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. 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.
- Model-specific harness that reduces splices and speeds installation.
- Distribution hardware with fused connection points for clean accessory feeds.
- Bracket, reinforced, to resist shock and vibration.
- Clear documentation for routing/termination of harness and distribution.
| Item | Role | Why it matters |
|---|---|---|
| Secondary AGM cell | Adds capacity | Keeps starter ready while running accessories |
| 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 | Neat fused circuits for lights and audio |
Parts are off-road ready and sealed as needed for dust/moisture resistance. Integration with existing charge/accessory circuits keeps routing tidy and reliable.
Easy, Straightforward Install
A straightforward install keeps your rig trail-ready without hours in the garage.
Begin with a clean workspace and lay out labeled parts. Mount the bracket, place the second cell, and route the harness to labeled terminals.
Key Position Behavior Made Simple
With the key ON, the 80A isolator links sources; key OFF keeps the starter isolated. 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 supplied hardware for clean grounds and fused distribution rather than daisy-chaining.
| Step | What to do | Why it matters |
|---|---|---|
| Mount bracket | Bolt into reinforced points | Handles vibration and maintains clamp load |
| 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. Properly rated isolator and cables stabilize delivery and protect the starter on extended rides.
Performance, Charging, and Long-Term Maintenance
Robust, steady power sustains aftermarket electronics under load. Proper charging and routine care make that reliability repeatable season after season.
Expect steadier voltage with better performance for amps, winches, and high-output lights. The auxiliary AGM trims voltage dips on spikes, keeping sound clean and lights bright.
Use a charger/maintainer to prevent sulfation
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.
- Key OFF isolation preserves stock battery health.
- Running engine alternator replenishes reserves for efficient recharge on long rides.
- Sealed, vibration-resistant agm battery construction reduces damage from rough terrain.
| Aspect | Benefit | Action |
|---|---|---|
| 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 | Do routine maintenance charging on sealed cells |
Tip: Keep a suitable maintainer handy to stay topped up. It cuts surprises and preserves next-morning starts on every trip.
