I'm an information sponge and tend to learn fast so hit me with it !
Do you guys use brushless or brushed? Also where do you buy your motors,esc's, etc. Those places usually have good technical information and gives me a reference point cost wise.
Also another topic i've been meaning to research. The new hybrid vehicles can they be converted to electric only or is that too large of an undertaking? Is there an electric only coming out any time soon?

I understand you work with the e-moli's and A123 batteries. I've got e-moli's on my brushless cyclone and crystalyte e-bikes and they're great. I'm using the stock milwaukee battery packs and connector blocks but I was thinking if i wanted to build a bigger pack, i'd have to take the cells out of the case and bundle them more densly-- something you already do. I checked out your site and you don't seem to have packs for 56v. is this only because rc folks don't need such high voltage or is there a technical reason? do you know of a way of conveniently charging a high voltage pack without having to separate them back into 28v?

If you would have asked me 1 month ago i would have said emoli. But now it's a123 all the way.

quick question about the milwaukee packs. you spoke of the e-moli bms needing a low voltage cut-off to prolong the life of the batteries. i believe the milwaukee batteries have this but i want to confirm this with you. I ran the batteries down completely about twice. when i measured the output voltage, my dvm read around 8.5 ~ 9 volts. I'm hoping i got this reading because the BMS stepped in and said, "no way! charge me first! ".
