Well, some airports are different. I would just make sure your connecting flight is leaving in the same terminal and that you are not responsible for claiming and transferring your own baggage.
A simple phone call to the place where you purchased the ticket should do to find out the exact protocol of your flight.
Although, something
@retired1 told me was "Don't take anything you wouldn't be okay with losing"
So, If you would be really upset about losing it, I would head over and get something you could lose without too much grief, some kinda clone, or something. I know that within the checked baggage batteries have been known to start fires.... so I would be worried about that if I checked it.

Drones and RC helicopters use the same type of batteries. Read the article, LiPo batteries can catch fire on board planes, so LEGALLY you need to carry it on. the link suggests putting batteries in some type of Battery safe bag, but, on carry on people are able to deal with small fires made by batteries. So the bags are not really necessary, but it is neccessary to carry on, as oppose to risk a fire with the luggage
I would check all your tanks, RDA's and juice, and carry on anything with batteries.
SInce you are only flying out, I doubt it will be a problem.
But if you can, grab a cheap mech clone or something or take a device you dont care about. Then no hassles.
Remember though, Never check batteries. Safety is most important.
