Product Description
Tired of using smaller batteries for an all-day game? Here's your solution!
One of the main issues encountered with the G&G ARP9 is the limited battery spacing to operate conventional sized LiPo batteries to endure a long-lasting skirmish event.Once the LiPo was installed into the stock compartment, it's difficult to fit the MOSFET, fuse and cables back inside without the risk of overbending (which weakens the circuit over time). By offering additional spacing inside the compartment, the Battery Extension Unit (BEU) is designed specifically to relieve all stresses on the ARP9's components, while protecting it throughout to extend its durability. There are crevice's on each side of the BEU to maintain a constant flow of ventilation to the battery and components to prevent a buildup of heat.The BEU is designed to fit beautifully with the ARP9's original design by sitting seamlessly inside the stock compartment with no modification needed to install. Made of strong, flexible nylon that is resistant to BB impact and rough handling.

Gets the job done. A bit flimsy for the price. Overall, average and overpriced.

I'm a little neutral on this one. I got this for my son's G&G ARP 556. While it is true that you can put bigger batteries in, I still feel like it's a tight fit and I worry about crushing the mosfet, pinching wires, etc. He uses a Titan Power 7.4v 3000mAh battery. Like it said, it fits, but it's still feels a little tight to me. I think they could improve this a little and then it would be a 5 start product (in my opinion).

You can put bigger batteries in and not have to bend the wires and worry about them breaking
