In this video, Matt discusses about an item which is sometimes taken for granted just like the dump pouch but is valuable for users of AEGS, especially the compact ones. The PEQ Battery boxes can take in the batteries required to power the AEGs when there is no space in the AEG to put one, as the firearms that they take inspiration from usually are designed without batteries in mind and AEG manufacturers are creative enough to put some space in the AEG. But if all things fail, it's the PEQ Battery Case to the rescue which you can find at Evike.com.
