DS18 Second Battery Upgrade Kit with 80A Isolator for the Can-Am Maverick X3 (2017+)

Add Reliable Auxiliary Power Without Sacrificing Starting Power
If you’re running a full audio system, lighting setup, or multiple accessories on your Maverick X3, a second battery isn’t optional — it’s smart. The DS18 Second Battery Upgrade Kit gives you a clean, OEM-style solution to safely add an auxiliary battery to your 2017 & up Can-Am Maverick X3. Designed for rear seat location installation, this kit includes everything needed to properly isolate and manage dual batteries while keeping your starting power protected. The included 80A Battery Isolator Relay automatically separates your main and auxiliary batteries when the vehicle is off, preserving charge on your primary battery. When the ignition is engaged, both batteries charge together while riding. If your accessory battery drains, your main battery remains protected so you can still start your machine. This kit includes a coated metal dual battery bracket, power distribution block, and marine-grade tinned OFC wiring for durability in harsh off-road conditions. Clean install. Protected starting power. Reliable accessory performance.
