Please sell an external battery charger that can be used to charge one or more Prism batteries outside of the camera. That way the camera could still be used while spare batteries are charging, and batteries could be quick-swapped easily.
I own two GoPros and a Prism. I have extra batteries and external chargers for the GoPros and it helps me keep everything running all day long when I'm doing a track shoot or an event blog. The only thing stopping me from using the Prism for these tasks it instead is that once the battery runs out the camera is out of commission for a few hours while you use it to charge.
If not Sena, I hope the aftermarket will step up, the same way that Wasabi Batteries and chargers started appearing for the GoPro.
