Murman did this: "I modded my SF so that the canopy would break away in a crash. I used velcro to hold the battery to the canopy and then tiny rare earth magnets to hold the canopy to the deck. Since the battery is the heaviest part of the SF, my thinking was that if it broke free in a crash then the SF itself wouldn't get damaged. It actually worked very well and I'm sure it saved having to make some repairs."
The battery is nicely protected as you can see.
