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. The 80 amp isolator links both sources with Key ON and isolates the starting unit with Key OFF so accessory loads draw from the secondary cell instead of the factory one.
Run accessories without draining 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
The isolator-driven system automatically prioritizes preserving stock battery so your machine cranks strong after a long night with electronics running.
- Reserve capacity: A second battery gives extra amp hours for high-draw gear at camp or on long rides.
- Reduced strain: Offloading accessories reduces stress on the starting circuit and components.
- Automatic management: Automatic behavior via key position; no manual switch needed.

Charging, Performance, and Long-Term Maintenance
Robust, steady power sustains aftermarket electronics under load. Proper charging and routine care make that reliability repeatable season after season.
Expect steadier voltage and improved performance for audio 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
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.
- Stock battery health is preserved by isolating starter power Key OFF.
- When running, the alternator replenishes reserves for efficient recovery on long rides.
- Sealed, vibration-resistant AGM design curbs damage over rough terrain.
| Area | Benefit | What to do |
|---|---|---|
| Performance | Steadier voltage under load | Add a secondary AGM to support high-draw gear |
| Charging | Lower long-term capacity loss | Use a quality charger/maintainer between rides |
| Long-term care | Longer service life | Do routine maintenance charging on sealed cells |
Pro tip: Keep a suitable maintainer handy to stay topped up. This reduces surprises and preserves morning starts trip after trip.
