What are the output voltages of B-port and round-port of V-port battery in broadcast class?

The output voltage of V-port and B-port camera batteries is 14.8V, which consists of four series of 3.7V 18650 batteries.

The circular port on the battery box is connected in parallel to the same port terminal of 14.8V output/input.

Our only film and television equipment factory, the V-port battery manufactured in recent years, in order to adapt to the peripheral auxiliary power supply, has added a USB output port, which is only used as 5V output, and the current is about 2A.

Usually 12V camera is a wide voltage circuit, so it is ok to use 9.6V- 18V voltage.
