Questions about SmallRig NP-FZ100 Set

It is probably about this decoding chip that is installed in the battery: "The battery is equipped with a fully-fledged decoding chip and supports various cameras perfectly without causing pop-up windows." This is why incompatibility is pointed out. However, this does not mean that you cannot use these batteries in an FX30. It is otherwise a normal 3rd party NP-FZ100 battery. The camera will simply display the message that it is not an original battery.

I have also noticed that the batteries are not always fully charged. This is probably to protect the batteries.

For me with Sony A7IV so far without problems, but only as a backup in case of emergency (e.g. no experience in extreme use in cold weather or for longevity)

Hello Androne The batteries are included. However, the performance is not as good as the originals. But excellent for the price!

Yes, this is the right one. Attention...it charges very slowly..but gently...

Yes, these are the right batteries for your Alpha IV.
