I can change the battery if it runs out of a flight session to full battery. For once, something clever! It always pays to keep a spare battery aboard!

Original battery last around an hour and a 32 gig card is about half full at the best resolution in that time frame. So instead of an aftermarket second battery I went original as the price including shipping is very good. this provides 2 hours HD recording with minimal changing. A+++

Un accessoire indispensable pour prolonger la durée de prise de vue. La batterie est identique à celle fournie d'origine

I just purchased my RunCam2 and wanted to be prepared so bought two spare batteries. These are not easy to come by elsewhere and were cheaper each when buying two. I also know that I have the correct battery and not a counterfeit. Service was fast and the batteries work just fine.
