I know this is probably asking a lot and can be a risk but. I would really like it if you could stock different sizes of batteries. I know that you are not a big battery vendor that has a ton of different brands and sizes but Admiral batteries are VERY NICE. I myself am flying Helis and the new fad is 450 class helis that operate on a 6s battery. Check TRex 450 Dominator.
Not saying any particular size but going outside of what usually goes in your planes.
