The IDX System Technology SB-U50-PD 48Wh USB-C Lithium-Ion Battery with BP-U Series is a Lithium-Ion pack for any camera that takes BP-U Series batteries, offering 48 Wh capacity. Its USB output supplies 20 V for charging or running small devices off the same pack. The LED on the body reports remaining charge. It sits under the 100 Wh mark, so airline rules allow it in carry-on without prior approval.

14.54 V Output
Supplies 14.54 V through the mount, which is the level the cameras and accessories on this system expect.
Lithium-Ion

Accessory Outputs
Carries a D-Tap output for accessories like monitors, transmitters, or lens control systems.
35 W Maximum Draw

LED Charge Indicator
An LED on the body reports remaining charge without powering the rig up.
