BEU - Battery Extension Unit - FITS G&G ARP9 ARP556 RAIDER 2.0E

Battery Extension Unit - BEU

This easy to install insert just clips into place and gives you approx 60% more battery space. Anyone who has used an ARP9 will know that the space to install the battery is very limited, even for the standard 11.1v designed for it. This makes a welcome addition for anyone wanting to install a battery with a higher MAH rating or even the standard battery will fit much easier.

We have tested this with the following G&G guns

ARP9
ARP556
CM16 Raider 2.0E
CMF-16K

It may work with other guns and brands but we cannot guarantee it.
