Li-Ion Power Tool cells work great for RC!

If anyone needs some let me know.

If I had to buy a big pack again I would but li po's they are just easier to deal with. Flat, lighter and smaller.

No thanks. I need to get another 3000mah cell. I would have gotten lipos, but I couldn't find any that were the shape I need. I want something that is the same size as a 6 cell NiMH brick pack, and 4 Emoli cells are almost perfect. Commonsense RC has a lipo that was close, but I decided to go out on a limb and try the li-ions.

Look at my avatar, and you can see how I'm restricted in my battery selection.

I am still looking for "the perfect cells" to use for my race Revo. I was waiting for DeWalts M1 cell packs to come out, but I don't think they will work as they will most likely be only 2.2Ah. No telling for sure until someone gets a pack and pulls the cells out. I'm still hoping they will be ~3Ah each because I want at least 25 minutes of runtime, and they have a higher discharge and charge rating.

Because I'm impatient, I'm now looking at the emoli cells from the V28 packs (3Ah per cell). However, those are unofficially rated for only 15C (45A) or 20C bursts (60A) from the temperature vs amperage graphs someone over at rcgroups compiled. I would get these, but would a 10XL motor pull more current than this with a 9-10lb truck? The motor is rated for around 66A. I know the motor won't pull that current all the time, but I don't want to hurt the cells. Also should I go with 5s or 6s?
