I was just at my local battery shop to get some packs built, but to my surprize they barely ever use NiMH cells. They said they just don't have the power output that are required by most of their applications (of which are mostly not RC). So I got them to build me some 1900 matched packs. The price was right and with the promise of a little more power over the competition I was sold. Did I get suckered?
