The Airtech Studios Amoeba Battery Extension Unit is designed to fit on Amoeba AEG guns:  AM13, AM14, and AM15.  Comes in either black or dark earth tan colors.  Very easy to install so you can add longer and bigger batteries in your rear stock/buffer area.  With it installed, you can use 9.6v 1600mah nun-chuck, and any longer 11.1v batteries in it, with extra room to spare.  This is a must have for those that want flexibility with battery space.  Can fit up to a Titan 3000 nun-chuck 11.1v.

Installation is drop-in, no tools or anything needed.  Simply pop in place to extend its buffer tube area length.

One of the main issues encountered with the Ares Amoeba AM-013, AM-014, AM-015 series is the limited battery space to use the conventional sized Li-Po batteries. Instead, you are required to use a couple of smaller sized variants which is difficult to last a whole day of gaming.

The Airtech Battery Extension Unit will provide you with double the amount of battery space to utilize with no modification required for the installation. The extension units are made with strong nylon that is resistant to BB impact or rough handling. A video on installation and handling is here:
