Lipo battery ammo box storage with drywall and FireGuard spray. 

Put a bent tube on the outlets so it doesnt just shoot flames into the air

Great insurance. Thanks for sharing 🐭👍

Better safe than sorry for sure. I have mine in a big ammo can drilled for pressure relief and each battery is in a sealed lipo bag and then in a couple of the bigger zippered fireproof bags as well inside the can.

They only go off while charging but I agree better safe then sorry.
