Default Crash lipo protection

New to eletc flite is there a way to protect lipo batt starting a fire in airplane crash? I fly at home field w 40 acres of warm season grasses in CRP that will burn all seasons.

I would recommend 4 things to minimise the risk of a LiPO fire
1. Don't crash
2. If you must crash - do it gently. Avoid flying 'fast' planes when the ground fire risk is greatest.
3. Build the battery box in such a way that the LiPo has a 'crumple zone' ahead of it (as big as possible) so that in a sudden impact the g loading on the battery is reduced as structure breaks up.
4. Avoid surrounding the LiPo with anything that might pierce it. In a realyl severe crash as a conventional close fitting play battery box splinters it is quite capable of piercing a soft LiPo case.
Because a foam plane gives and crumples a LiPo is much less likely to get damaged badly enough to cause a fire.

A LiPo is surprisingly tough. I had one fall out of a plane from 150 feet onto grass with no damage. It is still in use!

Try one of these soft silicone batt covers, just remember that the battery will run hotter the more fire protection/padding you put around it: http://www.hobbyking.com/hobbyking/s...4S_White_.html

or one of these:

I have had some pretty nasty crashes and bent up and trashed several batteries (fat old man trying to learn to fly 3D) but (knock on wood) have never had a battery fire, or even seen one other than on videos for that matter. If you are really worried about it get a 5lb ABC fire extinguisher and keep it handy. It won't put out the battery fire but will control the spread to the surrounding grassy areas.
