First, let me welcome you to the Your Micro forums.

Second, in response to your questions, I recommend you try contacting HPI Racing to inquire about the 45T motor specifications. The information mentioned on the web pages indicate that best results are obtained with 6V 600mAh battery pack. I am sure that you could easily use a 2S Lipo pack of almost any mAh rating. I have used this motor on a 5-cell 1400mAh NiMH battery pack as well as with a 2S 900mAh Lipo battery with excellent results.

You may use a Lipo battery with brushed or brushless motors. The thing to watch for with a brushed motor system is not to let the battery discharge too much. A Lipo battery does not tolerate being discharged too much. Most brushless ESC's include a low battery cutoff but most micro brushed system do not.

I'm not sure which ESC has the lowest amperage or why this might be useful to you.

A very economical 2S Lipo battery that I can recommend is from Deal Extreme. Check for the Mystery 7.4v 900mAh Lipo with a price of $8.20 and FREE shipping.
