A few months ago I began racing in a "spec" touring car class that includes hand out 2000Mah NiCD batteries (6 cell 7.2V). It has been a while since I really tried to get the most from these packs and have been struggling at each event. These are low grade, sport, NiCD batteries .... however it seems to me that others may be getting more from their batteries than I do (run time and punch). Anyway, I was curious if someone could help refresh my memory on the best way to charge and discharge. Thanks.
