Battery supplies need some fine tuning
The battery's terminals are reversed from stock, making it a really tight stretch for the cables. I mounted the provided terminals first, being sure to position the posts towards the wires, especially the hot side. The factory connection rings are too small to fit on the provided battery terminal posts! Mine is a 2018. I had to drill out the holes to get them to fit. It comes with wing nuts for the terminal posts...that's a fail. I also got the optima battery tray. Worked very well ($100 for an aluminum plate, but keeps it in place well). It came with a stick on 2" square pad...no idea where that was to go. I had some extra wires/fuses to attach for stereo, fuse block, etc. I mounted and zip tied everything nice and neat before realizing the cover wouldn't go back on. Had to redo accessory wires. Be sure to test fit the cover before finalizing wire locations. I would have given this 3 stars, but had to add another for the exceptional customer service from slingmods!

Optima Battery
Received the order in a timely manner like always. I was concerned about how the box was tore thinking that maybe the battery had been damaged, but there wasn't any damage to the battery that could be seen. Also got the updated battery box for the Optima. Finally got the battery box installed after having to make adjustments to the holes in the mount on the slingshot itself. (Threaded holes wouldn't line up with the thru holes, so had to increase the size of the thru holes, but finally got it mounted.) Then got the battery in and hooked up, also hooked up the external jumper and a battery mender. Now it's already to get going once the warm weather comes in.

Thanks again for a good product, I only gave 4 stars due to the damaged package, and having to do the extra adjustments to get the battery box in.

Thanks Again

Great battery
I was running a lot of LEDs on my stock battery and it could take it. The yellow top works like a charm.
