Like I said... this might work for something to use on the ground for anything other than actual flying. There is to much at risk to use something that questionable during actual flight.

Are you saying you wouldn't risk one of your high dollar planes by using a pack that may fail??? Something that can be completely replaced for just a few dollars?? Rather narrow thinking when you can just blast that bad pack and go fly.
Well....... yeah.
I've told this story before, but here goes. My pattern plane, Venus II with an OS 1.20AX has a dual battery pack setup... both 5 cell NiMh packs. They are connected in parallel, each has it's own switch. I use a voltwatch2 on the plane to monitor battery condition and check it before and after each flight.
I was flying one day, I seem to reecall it was after the third flight or so, and after landing, I checked the packs, individually, as I usually do. Pack 1 checked out OK but pack 2 showed down in the red zone without moving any of the sticks. Battery pack 2 went bad during the flight.
Had I had only that one battery pack, well, my Venus II would be a pile of balsa and light ply.
The point here is that they can and do fail in flight. Adding the situation where the pack was "shocked" and probably temporarilly restored, well, that's just not worth it to me. Add the situation that if it happens where there may be several people there, and it fails as the plane is headed in the direction of the crowd.. well, I'm sure you get the picture.
