The Tanker Battery Extension Unit (TBEU) is designed specifically for the KWA PDW Series used to connect a larger battery to the gun while keeping it external to the gun's body. This allows players to use higher-capacity batteries for longer gameplay without compromising the aesthetics or functionality of the airsoft gun.
 
Effortless Installation!
By offering additional spacing inside the compartment, the Battery Extension Unit (TBEU™) is designed specifically to relieve all stresses on the KWA rifles components such as the MOSFET and to prevent the bending of electrical cables to protect it throughout, increasing its durability.
