I was just looking at an old link for a meter designed for electric modle aeroplanes, and
Eagle Tree came out with a new modle! to quote their web site:
"eLogger V3. In addition to greatly enhanced resolution and accuracy, the V3 now supports voltage to 70 volts, current to 100 amps (150 amps optional), GPS (with optional GPS Expander), 4x the logging capacity of the V2, Three Temperatures, and Throttle Logging (or logging of two RPMs)!"
the basic unit is $69, a screen for it is another $39, and best of all! a $149 GPS unit for it "ground speed, GPS altitude, distance to pilot, course, UTC timestamp, and more."
Currently my electric bike components are on a frame from the dump, once it's warm I'm going to move them to a better frame from the dump, finish the lithium battery pack and maybe get one of these dohickies.
