I just received my Hawk-Woods dummy L-mount to Hirose adapter and I'm awaiting a Naztech PB15000 battery cable with a female Hirose connector to be able to try this out.
I also purchased this very low profile 2200mAh, Sony NP-F570 L Series InfoLithium Battery to use in conjunction with the Hawk-Woods dummy cell.
I would also like to see a sled with a single NP-F inline and a small integrated buffer battery that can run the unit for 5 minutes for swapping batteries!! The L-mount sled with 7200-7800mah batteries are a definite no go!!
