Good to know: adding 18 amp hours to your UTV changes how you use lights and audio on long rides. That extra capacity lets accessories run longer while your starter stays 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.
Expect a fresh, sealed AGM that ships fully charged and hardware sized to match your vehicle. The four wheeler lift kit runs maintenance-free day to day, and a quality maintainer is advised to limit sulfation and extend service 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 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. With an 80A isolator, Key ON combines sources; Key OFF isolates the starter so accessories draw from the auxiliary battery.
Use accessories freely and preserve your stock battery
Run light bars, audio, GPS, and cabin heat while keeping the starter untouched. The accessory supply supplies steady voltage for sensitive electronics, reducing dimming and voltage dips when loads spike.
Confident cranks with stock starting kept intact
Because the isolator protects the stock cell, your engine still cranks strong after a full night of electronics.
- 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.
- Smart energy management: No manual switching required—system behavior is automatic based on key position.
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.
With an 80 amp isolator, sources link Key ON and the starter is isolated Key OFF. This automation prevents accessory draw from draining your starting source.
Heavy-duty mounting bracket built for vibration and impacts
The reinforced mount holds steady across washboard and big landings. It resists loosening and fatigue so the install stays tidy and serviceable.
UTV Stereo Platinum AGM: sealed, low-maintenance, long-life
Platinum Series AGM comes fresh and pre-charged. Sealed AGM means spill resistance, vibration toughness, and no routine maintenance.

Alternative Packages: DS18 bracket/wire-only and AKJ Offroad full kits
- AKJ Offroad offers another full kit 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.
Pick what fits your build—complete kit for convenience or modular parts to reuse gear. Clear fitment guidance cuts wrong orders and gets you the right parts first try.
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 options protect starting power and add capacity for lights/audio/recovery.
Primary 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.
- A reinforced bracket that secures the assembly against vibration and impacts.
- Clear documentation for routing/termination of harness and distribution.
| Item | Role | 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 | Simplifies install and service access |
| Distribution block & hardware | Fused accessory feeds | Neat fused circuits for lights and audio |
Parts are off-road ready and sealed as needed for dust/moisture resistance. It integrates with existing charging/accessory circuits for organized, reliable routing.
Straightforward Installation
A straightforward install keeps your rig trail-ready without 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 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 bracket placement and 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.
| Stage | Action | Why it matters |
|---|---|---|
| Mount bracket | Secure to reinforced points | Maintains clamp load under vibration |
| Place 2nd cell | Seat and fasten with clamp | Protects terminals and service access |
| Connect harness | Connect labeled leads/fuse points | Simplifies future upgrades and diagnostics |
Most mechanically inclined owners finish this installation with basic tools. The amp-rated isolator and proper cables keep power delivery steady and protect starting batteries during long rides.
Charging, Performance, and Long-Term Maintenance
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.
Charger/Maintainer: your sulfation prevention
Use a good maintainer to prevent sulfation, the primary cause of capacity loss in AGM batteries. 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.
- When running, the alternator replenishes reserves for efficient recovery on long rides.
- Sealed, vibration-resistant agm battery construction reduces damage from rough terrain.
| Area | 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 |
Pro tip: Keep a suitable maintainer handy to stay topped up. It cuts surprises and preserves next-morning starts on every trip.
