I just put in an order yesterday for a couple of things from hk yesterday and forgot to add a tx lipo for my 9x... Oops. Looking at the tx packs, I was wondering why you need a low discharge battery (ie 1C) and whether a high discharge (20C) would work OK instead. I'm no electrician, but I thought batteries discharge whatever is drawn from them. If that is true, could I use one of my 3s 20C batteries?
