Kinefinity GripBAT 4S

The GripBAT 4S is Kinefinity's higher-capacity handgrip battery for the MAVO and TERRA, built to pair with the SideGrip and stepping up from the earlier 45Wh unit to 52Wh. Even with a KineMON-5U monitor mounted on the camera, Kinefinity rates it for about 80 minutes of runtime, and it can double as a UPS-style backup if the camera is simultaneously running on a V-mount battery. It's built for handheld operators who want grip-mounted power rather than a separate battery plate on the rig.

• 52Wh capacity: up from the earlier 45Wh GripBAT, rated for about 80 minutes of runtime on MAVO/TERRA even with a KineMON-5U monitor attached.
• BP-U30 compatible: works with the BP-U30 battery, which also fits Sony FS5/FS7/FX6/FX9 cameras.
• UPS-style backup function: can keep the camera powered during a battery swap if it's also running on a V-mount battery at the same time.
• Built-in protection: overcurrent and overvoltage protection circuits with short-circuit recovery, plus a 4-LED capacity indicator.
