Included in this listing is 2x Sony NPF-550 batteries (no charger) that can power both transmitter and receiver for a decent length of time, but perhaps not quite a full day's shoot. I also have a small assortment of rigging accessories and cables (USB-C, HDMI) I'm happy to include if they'd be of any use - send me a message and I'll see if I can help!
