Optima Battery Box Upgrade for the Polaris Slingshot by TricLED
If you've looked inside the battery compartment of your Polaris Slingshot you've most likely noticed that the battery Polaris provided from the factory is quite small and doesn't really provide adequate Cold Cranking Amps (CCA) if you plan on adding stereo systems, auxillary lighting, etc. Another problem with the factory battery is that it's lead based and corrodes at the terminals and requires maintenance for longevity.

Our fix for this problem was to partner up with our buddies over at TricLED to introduce an "all aluminum" battery box for the Slingshot that allows you to perfectly integrate a Yellow, Blue or Red Optima SpiralCell Technology Battery. We've designed two battery boxes because the 2016 and 2017+ models Slingshot's utilize different factory battery setups. The Optima bracket itself is laser cut, light weight and all aluminum so it will never rust or corrode like steel.

If you've never used an Optima Deep Cycle Battery you will be amazed at the difference in comparison to stock.

Please make sure the Optima Battery you purchase is no larger than 10" x 6 7/8" x 7 13/16"

Optima Battery Box / Tray Features:

  • Laser Cut / Light Weight
  • All Aluminum to prevent Rust and Corrosion
  • Fits Optima Yellow, Blue or Red Top Batteries

Easy addition
If you want to add a larger battery this this plate makes it extremely easy. Fit nice and easy to install.

Took me hours to install the battery and battery box upgrade but I finally got done. It was a tight fit for the Optima yellow tap battery but this exactly what I needed. Thank you Sling Mod.

The tray doesn't fit
The 2 holes in the back of the tray don't line up at all! It's my second tray, the first one got replaced because the one that was sent was for a different year model. I'm going to have to cut the holes out myself so I've got to buy a tool for that. I'm not too happy. I've spent hours trying to make it fit. It's obviously not the best quality for $100.
