You have to keep in mind that the 3800mah is all relative. It will probabely run longer than your standard 3800 pack because it is lighter, therefore the batteries are pulling less weight... I probabely won't be stocking any other lipos in the near future, as I don't like the Li-Po technology for cars except for Li-Mn packs. More info on that soon. However, if you need anything from Apogee, let me know and I can special order it very easily. We actually have a few really cool products in the works that will be pretty awesome which is what I'm spending most of my time on these days :).
