power output

Yeah, that's the one I was thinking of, but I thought it was more. Cool. :)

Lol, found a little error in their website while looking around. Go to this page and hover over the orange menu buttons at the top and watch the wording starting on the third button...

Wow, nice find!
I picked up the Eagletree micropower, powerpanel lcd, temp and brushless inline rpm sensor.
I don't use Deans so I got the version with wire leads.
This little guy was worth the $$$ IMO

how could one determine what batteries are needed to feed a specific motor?
with that i mean; how does one know how many amps a setup will pull?
before you have it up and running?

Well, I would hook up a set of good NiMHs of the voltage I was looking at running just to get a baseline reading. Install the eagletree, and run it like you would at worst-case conditions (lots of stops and starts and heavy acceleration). After a few minutes, you should have enough data on the logger to see what your currents are. I'd probably look for a lipo whose continuous C rating is equal or more than the peak rating on the logger. A little overkill maybe, but the voltage drop will be more stable and the packs will run cooler.

i have yet another question.
if you want to crawl or so, would your best bet be running a 90/1 reduction or so and 20k rpm or run around 15/1 and only a few 1000 rpm's?
