GENEROUS BATTERY EXPANSION

By offering additional spacing inside the compartment, the Battery Extension Unit Unit (BEU™) is designed specifically to relieve all stresses on the ARP9/ 556's components such as the MOSFET and bending of electrical cables to protect it throughout, increasing its durability.
