Now here's something you don't see every day... batteries that exceed their advertised capacity! I put one of my 24v 18Ah packs on a CBA II, and using a 0.9v/cell cutoff voltage it tested out at 19.44Ah on a 0.2c discharge. (unfortunately the CBA II only dissipates 100W) This pack has been used pretty hard for 15 cycles so far.
During discharge all 20 cells showed no more than 0.002v variation, and after full discharge only 0.019v variation.
EDIT: Using a 1.0v/cell cutoff capacity checks in around 19.3Ah for the picky
