The battery compartment holds four standard AA batteries at the same time. From left to right numbering 1.2.3.4, where numbers 1 and 4 are group A, numbers 2 and 3 are group B. Group A and group B are a serial structure if at least one battery in each group operates normally and has an output current, output voltage battery box is the sum of the highest voltage of one battery in group A and the highest voltage of one battery in group B. The output voltage must be controlled between 2.0v - 3.5v

At the top of the box are two IR lights with a strobe function for better identification during night operations.
