Optima Which Batterie??

Quote from TCB

I need to go to the Optima Battery, which one is best for the 2015 Sling? And what is really the difference between the Yellow, Red & Blue top??

Here's a link describing the difference. People are using yellow or blue on the Slingshot. I would go with the blue, personally...

Compare OPTIMA® REDTOP vs. YELLOWTOP vs. BLUETOP Batteries | OPTIMA Marine and Car Batteries

Part number for blue that fits the Slingshot is 8016-103; size 34 battery. This will work plug & play for 2015's. For the 2016 & up with the crappy dinky batteries, you will need the adapter battery tray available from our vendors...

Yes,,, Blue top for me worked fine...No additional modification - just went right in. Have had it for about 4 or 5 months now.
