I was thinking, how important is a battery backup? Just as important as a file backup on your computer? Imagine not backing up any of your files on your computer and then the HD crashing and losing everything. Thats how i feel with the Phantom now.. Why not develop an intelligent battery where there is a reserve smaller capacity battery inside the Phantom which syncs with the external battery and keeps a 5-10% charge in the reserve... This will prevent the battery fail issues etc... What do you guys think?
