Why a Can-Am Dual Battery Kit Makes Sense for Your Next Ride
When your rig needs long nights of lights and music, a dedicated secondary power source keeps the starter ready for the moment that matters. 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.
Power accessories while protecting 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 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.
- Less wear: Moving accessory load off the starter lowers wear on circuits/components.
- Smart energy 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. The design pairs automatic energy management with a rugged mount and sealed cells to keep electronics running without risking the starter.
With an 80 amp isolator, sources link Key ON and the starter is isolated Key OFF. That automation stops accessories from draining the starter.

Performance, Charging, 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.
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.
Use a charger/maintainer to prevent sulfation
Regular charging with a quality maintainer prevents sulfation, which is the leading cause of capacity loss in agm battery designs. 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 | 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 compatible maintainer on hand so your batteries stay topped off. That reduces surprises and helps preserve next-morning starts on every trip.
