Of course, far better to try to prevent that from happening in the first place. Since I don't have a charging dock anyway, I've taped over my positive contact on the tail with electrical tape. Hopefully SWM comes out with a prettier solution.
And of course, this sort of mod to the carrier is by-passing the fuse, so you are at risk of shorting out the cells (if the tail contacts are still exposed). Better safe than sorry when it comes to a risk of shorting batteries, in my view (i.e., I don't like relying on fuses or protection circuits). A proper physical lock-out is necessary here.
