    Description
    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.

    We recommend our  UTV Stereo 12V Automatic Charger/Maintainer, or our UTVS Dual Bank Battery Charger/Maintainer

    Features:

    • Gain +20 amp hours when added to the 20Ah OEM starting battery.
    • Run accessories while the vehicle is off without draining the starting battery.
    • Completely isolated system - 2nd battery is completely disconnected from the starting battery while the vehicle is off. Starting battery charges the 2nd battery  -while the vehicle is running.
    • Plugs directly into the factory accessory plug for easy integration.

    • High current 8 AWG pure copper power wire.
