Quick fact: with 18 additional amp hours, long rides feel different for lights and sound. That extra capacity lets accessories run longer while your starter stays protected.
A purpose-built 80A isolator links both batteries Key ON and isolates the starter Key OFF so accessories pull from the second battery. A heavy-duty mount resists vibration and impacts for true off-road service.
Arrives fresh, sealed AGM and fully charged and hardware sized to match your vehicle. The Honda rancher 420 radiator relocation/snorkel combo kit kit runs maintenance-free day to day, and a quality maintainer is advised to limit sulfation and extend service 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
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.
Use accessories freely and preserve 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
An isolator-managed system preserves the stock battery so cranking stays strong after long accessory use.
- Reserve capacity: 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.
- Automatic management: No manual switching required—system behavior is automatic based on key position.
Can-Am Dual Battery Kit: Features & Benefits
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.

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 if you’ve already got a compatible battery. 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.
- Harness, model-specific, to simplify wiring and speed install.
- Distribution hardware featuring fused points for clean accessory feeds.
- Reinforced bracket to secure components against vibration/impacts.
- Clear documentation for routing/termination of harness and distribution.
| 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 | Prevents accessory draw from draining starter |
| Model harness | Wiring link | Simplifies install and service access |
| Distribution block & hardware | Clean accessory feeds | Neat fused circuits for lights and audio |
All parts are selected for off-road use and sealed where needed to resist dust and moisture. The complete package integrates with existing charge and accessory circuits so routing stays organized and reliable.
Installation Made Straightforward
Simple installation keeps you trail-ready without losing hours in the garage.
Begin with a clean workspace and lay out 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. This design ensures accessories pull from the auxiliary so the starter remains reserved after long stops.
Secure mounting + clean harness routing
Use factory routing, secure with clips, and sleeve abrasion 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 | Maintains clamp load under vibration |
| Place 2nd cell | Seat and fasten with clamp | Protects terminals and service access |
| Connect harness | Follow labeled leads and fuse points | Makes upgrades and diagnostics easier |
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
Strong, steady power keeps your aftermarket electronics UTV setup performing under heavy 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. A dedicated auxiliary AGM reduces spike-related dips, keeping audio clean and lights 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 between trips to preserve capacity and extend life.
- Stock battery health is preserved by isolating starter power Key OFF.
- While running, the alternator replenishes reserves so long rides restore charge efficiently.
- Vibration-resistant sealed AGM construction reduces rough-terrain damage.
| Area | Benefit | Action |
|---|---|---|
| Performance | Steadier voltage under load | Add a secondary AGM to support high-draw gear |
| 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 |
Tip: Keep a compatible maintainer on hand so your batteries stay topped off. It cuts surprises and preserves next-morning starts on every trip.
