Boost battery power with UTV Stereo's auxiliary battery solution! Providing more voltage to ensure that your stereo plays longer, your lights shine brighter and your aftermarket accessories function at peak performance. The isolation system allows for the use of aftermarket accessories to draw directly from the secondary battery when the key is off, isolating the starting battery which ensures that your X3 will always start! Once the vehicle’s motor is started, the isolator engages, and the vehicle’s charging system will charge both batteries.
The UTV Stereo Platinum Series Batteries are the longest lasting, most durable AGM (Absorbent Glass Mat) batteries on the market. They are spill proof, vibration & shock resistant, and can be installed in any orientation. Our batteries give you the ability to add aftermarket electronics to your UTV by providing you with more storage capacity and higher power output.
To maintain its peak performance, it is imperative to keep this AGM battery connected to a reliable battery charger/maintainer during storage.

heavy-duty mounting bracket
Utilizes a heavy-duty mounting bracket to ensure a secure, long-lasting installation, even in the toughest conditions. Perfect for withstanding vibration, impacts, and demanding environments.
isolate your second battery
The 80 amp battery isolator allows you to isolate the new secondary AGM battery while the vehicle's ignition is off, preserving your stock battery for starting. This system is quite simple: Key ON - both batteries are connected to X3's power system, Key OFF- the starting battery is isolated from the X3's power system, only drawing power from the 55 amp battery. It's that simple, and it works great.
