After reading in this forum and also on youtube and see how easily the batteries mechanically can malfunction and causing the spark to fall mid air makes me very nervous flying my spark. I've been very carefull and inspect the battery latches and even with that I am still nervous. What if..
So, I found two elastic bands about 1 inch in diameter each and created as seen in photo's.
Doesn't interfere swapping batteries. Just flip bands up if wanna replace battery. Hopefully this idea will be helpfull to most who is worried about batteries dislatching mid air.

Good idea. Think I'll try that as well.

I ordered these there like 10bux for 2

Hi sir. Please ensure that the accessory will not hinder the propeller. I believe that if you install the battery in a correct way, it won't pop out. Thanks for your attention.

I have been flying like that for a while now in sport mode and honestly .. I am not worried about the battery coming off at all.
