Polaris Slingshot Dual Battery Kit (2020+) | SlingMods

🛒 2020+ Polaris Slingshot Dual Battery Kit available here: https://www.slingmods.com/polaris-sli... If you're running aftermarket 12v mods on your Slingshot such as our UnderGlow Lighting Kit or perhaps an aftermarket stereo system, then it's probably crossed your mind that the factory Slingshot battery really isn't intended to run mods with the ignition off for extended periods of time. If you do, you face the risk of potentially leaving yourself stranded with a dead battery. So to address this issue, we've partnered up with the team over at TricLED to bring you guys a dual battery kit for all 2020 & newer Polaris Slingshot models. This kit features a custom designed aluminum battery tray to mount your secondary battery in the rear of the Slingshot, you'll also get all necessary power and ground cables, and inline fuse holder with fuse, plastic looming and most importantly a VSR also known as a "Voltage Sensitive Relay". A VSR allows your primary battery to automatically start charging your secondary battery when the primary battery voltage exceeds 13.3 Volts, which is anytime your engine is running or if you're Slingshot is parked with a battery charger on it. The VSR has a little LED indicator light on it that will illuminate when this 13.3 volts is achieved and the secondary battery starts charging. Now, when your engine is off, if your primary battery dips below 12.8 volts for any reason, the VSR will detect that voltage drop, the LED indicator light on the VSR will turn off, and automatically stop charging your secondary battery, to ensure your primary battery is always charged and ready to start your Slingshot.
