RE: Mini Ultra Stick
You will probably end up making a number of adapter cables to fit your battery collection as it grows. I put a Deans on the leads from my charger, then made a cable to plug into the Deans but output to a Z connector (for my transmitter batteries) and another one with a JST output (for my older NimH batteries) and another one with alligator clips (fir the battery in my field box) and another one with the ThunderPower connector for my buddies batteries (for when he can't get his Blinky to work).
(I have a Triton charger, for Lead, NiCd, NimH and Lipo batteries - and short adapter cables are really cheap to make)
