Hi Frank,
I stand by my statement about NiCad's for this reason. Over several
seasons of racing model cars and boats, I discovered a battery balancing
technique that apparently everyone else knew. A monthly discharging of the
6 cell sub-C packs with a resistor and then a shorting strap, to bring the
pack to dead, dead, dead. It sits that way for a couple of days to a week
with the strap in place and is then recharged. First trickle charge for
about an hour and then fast rate charge to completion. The result is a pack
with a slightly lower internal resistance, as measured by its increased
voltage, and an incredibly well balanced pack. Have never had a pack croak
out with this treatment, but note, the total pack capacity seems to be
reduced to about the level of the worst cell in the pack. FYI, and I know
it doesn't seem reasonable.
Best Regards,
Nick Pasch
