14.4 volt, 56Wh battery for XDCAM EX camcorders. The BP-U60 uses a communication line with the EX camcorder, whereby the precise remaining capacity can be displayed on the camcorder's LCD and viewfinder. The battery information display on LCD is available even while the camera power is off (not on EVF). The BP-U30 and BP-U60 also have LED displays to indicate the remaining capacity of the battery at the push of a button on the battery itself.
