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.
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.
Arrives fresh, sealed AGM and fully charged and hardware sized to match your vehicle. The rancher 420 radiator relocation kit kit runs maintenance-free day to day, but using a charger/maintainer helps prevent sulfation and lengthen life.
Shop online for clear fitment and fast delivery so a customer can move from order to install with minimal downtime. This smart upgrade preserves stock starting capacity while adding usable amp-hours for winches, lighting, and stereo power on every trail.
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. 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.
Run accessories without draining 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
The isolator-driven system automatically prioritizes preserving stock battery so your machine cranks strong after a long night with electronics running.
- Extra reserve: The auxiliary cell adds amp-hour reserve for high-draw gear on trail or at camp.
- Less wear: 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
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.
An 80A isolator ties sources Key ON and isolates the starter cell Key OFF. This automation prevents accessory draw from draining your starting source.
Heavy-duty bracket engineered for shock and vibration
A reinforced bracket anchors components through washboard trails and hard landings. It resists loosening and fatigue so the install stays tidy and serviceable.
UTV Stereo Platinum Series AGM: sealed design, maintenance-free, durable
Platinum Series AGM comes fresh and pre-charged. As a sealed agm battery, it resists spills and vibration and needs no routine maintenance.
More amp-hours than stock for lights/audio/accessories
- Gain about 18 amp hours versus stock for longer runtime with lights and audio.
- Steadier loaded voltage preserves audio clarity and lamp brightness at idle.
- Factory-friendly integration keeps installs neat and durable.
Can-Am Owners: Model Fitment and Options
Select the kit that matches factory mounts and wiring for your model.
Can-Am Maverick X3 owners can opt for a full second-battery kit with wiring/hardware for a quick upgrade. Already own an AGM? UTV Stereo’s mount-only option gives a clean 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: model-fit second battery kit for stock bay
Defender kits fit stock space and preserve access for service. Factory clearances remain intact while adding reliable auxiliary capacity.
Bracket-only and wiring kits for owners with an AGM
Cut costs with mount + wiring when you own a spare AGM. You get clean routing and solid mounting without buying extras.
Alternative Packages: DS18 bracket/wire-only and AKJ Offroad full kits
- Explore AKJ Offroad for another full package option.
- DS18 lists bracket/wire-only packages with free U.S. shipping advertised.
- Each product is engineered around model geometry so the install looks factory and stays secure on rough trails.

Kit Contents
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 already own a compatible cell. Both paths keep the starter reserved and give you usable extra capacity for lights, audio, and recovery gear.
Main components
- Battery isolator relay (80A) for charge management between sources.
- Harness, model-specific, to simplify wiring and speed install.
- Distribution hardware featuring fused points for clean accessory feeds.
- Bracket, reinforced, to resist shock and vibration.
- Documentation that guides harness routing and proper distribution termination.
| Component | 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 | Wiring link | Simplifies install and service access |
| Distribution block & hardware | Clean accessory feeds | Tidy fused circuits for lights/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
Install is straightforward so your rig stays trail-ready with minimal downtime.
Prep a clear workspace and lay out the labeled parts. Mount the reinforced bracket, set the 2nd cell in place, and follow the harness leads to each terminal.
Simple Key ON/Key OFF behavior
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
Route the harness along factory paths, secure it with clips, and add abrasion protection at pinch points. Use the supplied hardware to make clean grounds and fused distribution points instead of daisy-chaining accessory feeds.
| Stage | Action | 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 | Connect labeled leads/fuse points | Simplifies future upgrades and diagnostics |
Basic tools are enough for most mechanically inclined owners. Properly rated isolator and cables stabilize delivery and protect the starter on extended rides.
Charging, Performance, and Long-Term Maintenance
Robust, steady power sustains aftermarket electronics under 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 auxiliary AGM reduces spike-related dips, keeping audio clean and lights 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.
- Stock battery health is preserved by isolating starter power Key OFF.
- Running engine alternator replenishes reserves for efficient recharge on long rides.
- Vibration-resistant sealed AGM construction reduces rough-terrain damage.
| Area | Benefit | What to do |
|---|---|---|
| Performance | Stable voltage under load | Use a new secondary agm to support high-draw accessories |
| Charging | Lower long-term capacity loss | Employ a quality charger/maintainer between outings |
| Long-term care | Longer service life | Do routine maintenance charging on sealed cells |
Pro tip: Keep a suitable maintainer handy to stay topped up. That reduces surprises and helps preserve next-morning starts on every trip.
