Brian,
The memory of NIMH's is pure fallacy.
To give you a little background. I competatively fly and race radio control ELECTRIC planes and race cars. The competition is VERY fierce. Part of the competative edge is squeezing out every electron from our batteries. There is a whole science in battery technology and useage, in which I am well schooled. I have a flying wing that hits level flight speeds of 120 mph on 8 AA NIMH 's. The race cars do 40 - 70 mph depending on vehicle class. We use computerized battery chargers/cyclers which can cost from $75 to $ 600.00. Trust what I say!! I will as stated do a sticky on batteries, but do not have the time right now.
