The IndiPRO Tools D-Tap to LP-E6 Dummy Battery Cable for SmallHD Monitors features a slightly modified LP-E6 dummy battery for compatibility with SmallHD monitors that accept LP-E6 batteries. The cable allows you to power the monitor from a D-Tap power source. It regulates the 12-18V input voltage range of D-Tap sources to deliver a 7.2V output to your monitor via the dummy battery.
