Airtech Studios – BEU Battery Extension Unit (AM-013 / AM-014 / AM-015) – Black
 
Designed to solve tight battery space issues in the AM-series rifles.
 
The Airtech Studios Battery Extension Unit (BEU) is the ideal drop-in upgrade for Amoeba AM-013, AM-014, and AM-015 AEGs. By extending the internal battery compartment, it allows for better cable management, reduced wire strain, and the ability to fit longer and higher-capacity LiPo batteries with ease.
 
Key Features:
Specifically engineered for Amoeba AM-013 / 014 / 015 AEGs
Expands internal space within the rear stock section
Compatible with most common stick and buffer-style LiPo batteries
No permanent modifications required – quick and easy install
Protects wiring from crimping or excessive bending
Made from robust, injection-moulded polymer for long-term durability
 
Battle Nexus Workshop Notes:
We frequently use these units when upgrading AM-series builds that include MOSFETs or larger batteries. Without the BEU, space is extremely limited and can cause damage to internal wiring or battery cells. This unit is a trusted solution for performance builds.
 
Battle Nexus Safety Reminder (Battery Fitment)
Always ensure batteries fit comfortably within the extended space. Do not crush or force LiPo batteries into position. Always charge with a certified LiPo charger in a LiPo-safe bag, and never leave charging unattended.
