I got a nice 2s shorty lipo and some connectors (5mm) from http://www.smc-racing.net/
The battery labels are on the sides so you have a clean, black surface on the top!

The 5mm gold plated connectors (they don't come with the battery, you got to buy them separate) have a grub screw on the bottom so you can adjust the tension of the connector in the battery tube. How cool is that!


Instead of buying a charge cable, I'll make my own.
