Switronix has unveiled a new power cable for Canon DSLRs using the LP-E6 battery type (currently, the 5D Mark II, 7D and 60D).
The XP-DV-CH features a regulated 7.9v battery paddle (LP-E6 type) and an inline female p-tap connector for 12vdc, housed in an enclosure. It also includes both red and green LED indication to display battery power status. The cable can be used in association with a Switronix accessory or used solo with a PRO-X series lithium-ion battery product.
