Installing the PakTrakr

I took some time to install the PakTrakr modules today. I was a bit disappointed in the voltage measurements from the PakTrakr remotes, so I'll probably send them back for recalibration. Here are the voltages I measured:

Unit #1






Battery # Battery(V) PakTrakr(V) Difference(mV)
1 13.43 13.5 70
2 13.49 13.7 210
3 13.48 13.4 -80
4 13.49 13.9 410
5 13.52 13.9 380
6 13.28 12.9 -380




Unit #2






Battery # Battery(V) PakTrakr(V) Difference(mV)
1 13.41 13.5 90
2 13.46 13.7 240
3 13.47 13.4 -70
4 13.46 13.7 240
5 13.5 13.7 200
6 13.29 13.5 210

Unit #2 isn't too far off, but batteries 4, 5 and 6 on unit #1 have too much error to accurately determine the state of the pack. I contacted Ken Hall at PakTrakr today for advice before I send the units back.

To help with air resistance, I might run to the plastics store and cover the entire front grille with a sheet of ABS plastic to see if that cuts down on the drag as well as the cooling effect on the front batteries...

Yeah, that's similar to what I found with my PakTrakr. Glad it wasn't just me. Did you also check the temperature readouts? They are way different on my two remotes.
