Has anyone opened up the standard camera that comes with the FC40? I need to check some electrical connections and perhaps see about replacing a bad battery or bypassing it with a direct wiring to an external battery. I realize I can rig up the USB charger port to a battery; but, the internal problem may be something else. I was able to easily pop open the front were plastic tabs snap into a clear plastic interior cover. The backside appears to be where the battery is and the back cover is not popping off as easily. Need some pointers. Maybe find out who actually builds these to let me know how the back cover is attached. It does not seem to be glued making it openable. I don't want to wreak a 70$ camera if avoidable. I have searched the forums and internet finding nothing on this topic/project.
