Quick 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.
A purpose-built 80A isolator links both batteries Key ON and isolates the starter Key OFF so accessories pull from the second battery. Its heavy-duty mount resists vibration/impacts for real off-road use.
Arrives fresh, sealed AGM and fully charged plus vehicle-matched hardware. The Can Am plow kit kit runs maintenance-free day to day, though a charger or maintainer is recommended to prevent sulfation and extend 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.
Why Choose a Can-Am Dual Battery Kit for Your Next Adventure
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. You get steadier voltage to sensitive electronics, reducing dim and drop during load 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.
- Reduced strain: Moving accessory load off the starter lowers wear on circuits/components.
- Automatic management: No manual switches—key position controls behavior automatically.
Key Features & Benefits of the Can-Am Dual Battery Kit
Here’s what the upgrade delivers for trails and daily 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. That automation stops accessories from draining the starter.
Rugged mounting bracket for vibration and hits
A reinforced bracket anchors components through washboard trails and hard landings. Resistance to loosening and fatigue keeps installs tidy and easy to service.

- 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.
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 approaches aim for a factory look and secure fit.
Defender: tailored 2nd battery kit that fits the stock compartment
The Defender kit is built to fit the stock space and preserve service access. That keeps factory clearances intact while adding reliable second battery capacity.

Kit Contents
Here’s what you receive and how it protects the starter yet feeds accessories.
Choose a full package with a secondary agm battery or select the bracket-only route when you already have a compatible cell. Either way preserves the starter and adds usable capacity for lights, audio, and recovery tools.
Main components
- 80 amp battery isolator relay to manage charging/isolation.
- Model-specific harness to limit splices and speed installs.
- Power 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.
| Item | Function | Why it matters |
|---|---|---|
| Secondary AGM cell | Provides extra amp hours | Keeps starter ready while running accessories |
| 80A isolator relay | Controls charge/isolation | Stops accessory drain on starter |
| Model harness | Connects components | Easier installs and service access |
| Distribution block & hardware | Clean accessory feeds | Neat fused circuits for lights and audio |
All parts suit off-road duty, with sealing where needed against dust/moisture. The complete package integrates with existing charge and accessory circuits so routing stays organized 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 reinforced bracket, set the 2nd cell in place, and follow the harness leads to each terminal.
Simple behavior: Key ON/OFF
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
Use factory routing, secure with clips, and sleeve abrasion points. Supplied hardware enables clean grounds and fused feeds—avoid daisy-chains.
| Step | Action | Why it matters |
|---|---|---|
| Mount bracket | Secure to reinforced points | Handles vibration and maintains clamp load |
| Place 2nd cell | Seat battery and clamp firmly | Protects terminals and service access |
| Connect harness | Connect labeled leads/fuse points | Makes upgrades and diagnostics easier |
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, and Long-Term Maintenance
Strong, steady power keeps your aftermarket electronics UTV setup performing under heavy load. With proper charging and routine care, reliability repeats season after 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.
Prevent sulfation with a charger/maintainer
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.
- Running engine alternator replenishes reserves for efficient recharge on long rides.
- Sealed, vibration-resistant agm battery construction reduces damage from rough terrain.
| Area | Gain | Action |
|---|---|---|
| Performance | Steadier voltage under load | Use a new secondary agm to support high-draw accessories |
| Charging | Less capacity loss over time | Employ a quality charger/maintainer between outings |
| Long-term care | Longer service life | Pair sealed cells with routine maintenance charging |
Pro tip: Have a compatible maintainer ready to keep batteries topped. This reduces surprises and preserves morning starts trip after trip.
