If you need a flat pack for your transmitter, check out
www.cheapbatterypacks.com and they can make you whatever you need for pretty cheap. My Nomadio React only came with a 800 mAh pack. I was able to get 2 2500 mAh packs from cheapbatterypacks for the same price as one OEM 800mAh, and my battery packs are 2 years old and still take a full charge and work great!
