dont worry about quick release battery trays. standard tray with one thick velcro will do fine. It will take about 20-30 seconds to change the battery. If you can get your setup to last for 15 minutes thats 3 pit stops - 60-90seconds losts.

Nitro will pit 5-6 times with let say 5 seconds per pit stop thats 30 seconds.

You will have to make those 30-60 seconds lost on the track :)

Or if you can make 20minutes on one battery you should not worry at all.

In buggy it is just two body clips so it can be done really fast.
