Yeah, they do take up so much space, makes them hard to work with on any RC form factor. I am using the 15Ah A123 cells for a 16s pack in my ebike for two years now and they are running GREAT. I can get 35km or almost 22 miles range from the ~770 Wh pack, that's cruising at 55kph or 34mph. The cell iR doesn't even register on my 720i when doing individual cell testing. I have a long 3 foot lead running to the controller, so am going to shorten that up to get rid of some of the voltage drop... down to ~48volts under a 45 amp acceleration load.

These things could start a truck engine.
