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

Battery Box Tray
I have a 2019 SLR. Fits very tight. Couple of things I ran into. The factory negative terminal cable (12 inches) will not reach battery post. Had to get an 19 inch battery cable. The positive battery cable won't fit over the supplied post clamp threaded stud. I had to drill a bigger hole in positive battery cable. Don't over tighten the threaded ground stud. It breaks easily. Would be nice to have a install video on this version of battery tray.

Optima battery box
I recommend this product for anyone who wants to have a number of lights or accessories on your slingshot with the optima battery. It looks great and it was easy to install.

Easy enough to install. It’s larger than stock so it’s tight but the videos they provide helped a lot. Slingmods always has great customer service. Even when I call with a bone head question.
