The batteries that come with the Sony A7 series’ cameras have gotten a reputation for a short battery life. The size is small and they are advertised as getting 250 per charge. Of course, how many shots you actually get heavily depends on how you use it.

We are often shooting video or time lapse sequences which require long battery lives. We needed a way to extend the shooting time before we had to change batteries. Changing batteries means disturbing the camera which often is the last thing we want to do.

The key to this is the Sony AC adapter and a portable battery. We already had several Alien Bee Vagabonds which are lithium batteries that are part of our portable studio kit. Anyway, check out the vid for all the details.
