RWA likes nothing more than to push beyond the current bar setters and make something of even better quality and these 7.4V and 11.1V batteries will surely do the job. They can be used in airsoft aegs, RC cars and plays as well as transmitters. Make sure the compartment space is large enough for them as the dimensions are L=135mm, W=12mm, H=6mm for 7.4V and L=135mm, W=22mm, H=6mm for 11.1V.
The batteries come in forms of Small Tamiya, Large Tamiya, Large or Mini Deans.
