Li-Ion Power Tool cells work great for RC!

Brian, I run a 10XL on my E-Revo (setup to race) and I think or racing, 4S would be PERFECT. 15C should be plenty for this motor as well although i would personally go for a 2P setup. With the M1 cells a 2P setup will get you over 30 minutes of runtime I believe. It just depends on driving style. I've still only got 4 runs on my new IB4200s and they kept getting 5 minutes more every time. My last run was about 23 minutes of really hard running.

Only 4s? I got the 10xl so I could go with a higher voltage. Plus, I figured I would be a little easier on the throttle with ~20v as opposed to ~15v. Since the M1 cells are only 2.2Ah, it makes sense to go with a 2p setup, but then the cells weight as much (and take as much room if not more) as equivalent voltage/capacity NiMH cells. This is why I was looking at the emoli cells, which are 3Ah, and then use 5s or 6s for higher voltage.

On my relatively heavy bashing Revo (~13lbs), I get about 20-25 minutes of runtime on 14 GP3300 cells with an 8xl motor. I figured that motor draws substantially more current, so a similar battery setup (capacity/voltage wise) would last quite a bit longer on a 10xl. However, I've never raced, but I have heard racing is harder on batteries.
