Perfect kit for me as my FX30 battery could only be charged when the camera was plugged in.

One of my biggest dislikes about my FX30 was that it only came with 1 battery and had no exterior charging block to charge the battery outside of the camera. It is annoying to have to have the camera body be on my desk taking up a decent amount of space just to charge a battery that would normally come with a charging block. This one from K&F comes with 2 larger mAh batteries and an external block I can setup to charge my batteries outside of the cameras body.

The batteries have a slight bit more power storage than my OE Sony provided battery which is great as batteries tend to go through juice quite fast when shooting at higher resolutions. The fact that it also comes with 2 batteries makes sure that I can have extras charged and ready to go as I shoot footage throughout my sessions.

The batteries charge fairly quickly and fit into my FX30 perfectly with no fitment issues. I would highly recommend this battery kit to those that are looking for more batteries or for those who can only charge their batteries through the cameras body.
