When I want to "just go" to the field on the spur of the moment, I take
my fast charger with me, and charge them up. It takes about 5-10
minutes at the field. This is done with a pack (or radio) that has been
sitting around for a few weeks. It's not really good to fast charge a pack
that is dead....they get too hot, and it is said that it shortens the battery life.

Don't keep then on the charger all the time, that is not good either. I'm
talking about transmitter and reciever batteries. The batteries that power
electric cars are charged and discharged at very high rates, and get as hot
as the dickens. I don't really know about them.

I get usually about 10 years out of a reciever or transmitter battery. Most
times I just charge them overnight before a day of flying, usually about 12 hours
or so. I have friends with the fancy battery "cycle features" and such. Their
batteries only last about 3-4 years....go figure.

I really prefer not to fast charge batteries, when the slow charge is
the prefered method. I believe if the manufacturer wanted the batteries
fast charged, they would have provided a fast charger. I will admit that I am
old fashioned, and when something is working fine, I just keep doing it that
way.
