nimhs question

Everybody says nimhs don't need to be discharged since they do not develop memory like nicds. I just try to run mine down in my rc until I see it slow noticeably - time to charge. I have noticed over long haul my 7 and 8 cell packs seem to benefit for a slow discharge every so often. After the disch, they will take more of a charge and deliver a little bit more run time.
