What Brian said but if you are still looking for cells try dead laptop batteries. I have taken apart lots of packs that were dead and it's always the same thing one group of parallel cells are dead and the others are ok and usually measure about 3.8V or so. Most are a little larger in diameter .71" and a little longer at 2.5". They come in a a few different styles some are 3.6V others are 3.7V and the capacities are 1 ah to about 3ah. I have seen packs that are 6s2p,4s3p,3s3p,3s2p. They aren't really good for RC but some have found their way into my Tx and some flashlights and a few other devices.

Jeff The Warnings & Cautions discussed in this manual cant cover all possible conditions/situations. It must be understood that common sense and caution are factors which cant be built into this product.
