Hi Richard,

Here is one geared towards model airplanes, but it is relatively
inexpensive, $54, and it also will integrate the current and power
to give you amp-hrs and W-hrs.

Bob makes very good quality products. I have a NiCd battery charger of his
that is almost 20 years old. I can get a hundred charge/discharge cycles
out of battery packs using this charger.
