G&P has a nicely designed Flashlight-powerbank combo that is designed for AEGs. Rather than the usual powerbank that can charge mobile devices, this is a rail-mounted Powerbank that can power front-wired AEGs and with the integrated flashlight, can be used as a weaponlight as well. You can choose between the 11.1v and 7.4 versions that are available right now on Evike.com.
