The temp is in the 40s. Took it 200 feet down the grade and turned around and immediately it was going slow, as slow as you could walk.

We started out at 36.3V. At the bottom of the grade, starting uphill, the voltage dropped at various points to 32.9 V at its lowest and varied around 33V+. At the top of the grade, at rest, the battery climbed up to 35.8V after 30 seconds. Took off the seat and felt for heat. Everything was cold except the 12 o'clock terminal of the F/R switch, I think A2 wire, which was warmer than body temp, but not burning. This goes to a controller in the back but the terminal wasn't warm there.
