Power your Sony a77 II, a99 II, or a68 camera using a high-capacity D-Tap battery with this D-Tap to Sony NP-FM500H Dummy Battery Cable from Wooden Camera. The cable features a standard D-Tap connector on one end and a Sony NP-FM500H dummy battery on the other end.

A converter built into the cable steps down the typical 14.4V output of a professional V-mount or Gold mount battery's D-Tap output to the 7.2V camera voltage requirement. It also provides polarity protection so your battery and the cable will be damaged if plugged in the wrong way. The cable measures 20" in length.
