Lithium project question

[06lariat85]

So I have a basic Lithium Ion swap question...In the Florida heat during summer would these batteries tolerate being parking outside with the cart in direct sunlight for 6-8 hours? Obviously they would be under the seat in the tub but it would still get significantly hot in there I would imagine. I would like to be able to leave the cart at the beach access then ride home at the end of the day. Thanks!

I know this is a trivial question but I am trying to decide whether to undertake this project or just get lead acid replacements.
