I've done a lot of videos with GoPros and the batteries are always a problem. Charge em up and a day or so later they're down and haven't even been powered up. I've got probably at least a dozen including several piggy back high capacity aftermarket versions and they're better but not much. The remote batts are some better too but still not long life. In contrast my Canon and Panasonic still/vid cam batteries are never a problem. Charge em up and go on a week long trip and take a couple hundred pics and the batt still shows full. Same in the drawer for 6 months; still full. We got xperts in everything here....can somebody tell why the Gopro batts are crap?
