Was searching the Sony website this evening and I came across a Vertical Grip for the RX10M4. This grip does not mount to the camera but has an extension that allows you to use it on a tripod or monopod. What is a nice feature about this grip is that it holds 4 Sony or Watson batteries and you can apply power to charge all 4 batteries at once.
Here is the model and price information:
NPA-MQZ1K
Multi Battery Adapter Kit
MSRP $399.99
Thanks for the info, but at that price and not attachable I can change my battery as needed.
The battery for my Sony RX10 IV makes it through the full day. I carry a spare but never have needed it.
