7-cell vs. 2s lipoly

[pedeboi364]

well, at 98% doesn't the current return to normal? that was just an idea tho, would be cool. I'm thinking more along the lines of hitting my pede with a 9.9v pack. Like all the chicks say, "We'll make it fit baby." Anyways, would hobbycity be a trustable (is that a word?) retailer of A123 cells? 4 (or how ever many come in a developer kit) for $20 seems a touch low...

Not sure what you mean here. A typical lipo charger will charge at the set current until the voltage gets to 4.2v/cell. At that point, the voltage is held constant at 4.2v and the current slowly drops to a preset small value (something like 1/10 of the mAh rating).

Easier to just get a 3s A123 pack if you want 9.9v. Or, just use a normal 3s lipo pack and turn down the power on the ESC (depending on the ESC used).

I believe the word you are looking for is "trustworthy". And I'm not sure about them as I have never purchased from them, but other people seem to like them. IIRC, A123 cells are sold individually for ~$10 each. If you are getting 4 for $20, make sure they aren't the lower 1100mAh cells (or something like that).
