as there seems to be a few of you SUP persons who have these cameras ,can any one offer some information on batteries . i have just got a new wide angle pro and not sure which batteries will be the best . what does everyone use , if they are rechargeable what brand are they? are they niMH or lithium? does it make any difference to operation of the camera. i had another helmet camera and it did make a difference, any information would be great . thanks
