The thing as well for the ESCs from Rory as the IBF ones is, both can also do repairs on them.
And... well, the IBF one at least got a fuse itself, so to actually damage it, you'd need physical damage to it.
Place it somewhere nice and safe in the bot with some shock mounting, and that should do the trick.
Most bots i've seen became unmaneuverable due to loss of wheels and such way before anything ever came close to the expensive electronic parts. sometimes switch out a motor or gearbox, but that's it.
