Power your camera or other pro video equipment with the IDX CUE-H90 90Wh Compact Li-Ion V-Mount Battery System Technology. The battery can supply up to 16.8 VDC to the plate, and it can also provide up to 80W to power accessories through the integrated D-Tap output. CUE-H90 batteries feature a nominal voltage of 14.8 VDC, a maximum output voltage of 16.8 VDC, and a maximum 7A draw.
CUE-H-series batteries feature an even higher capacity than their CUE-D predecessor while maintaining the same internal pack design that isolates it for reliability and safety. There is also built-in prevention of overcharging, over-discharging, or overcurrent. IDX CUE-H90 batteries should be charged using IDX-branded chargers; third-party chargers may not charge CUE-H90 batteries correctly.
