More info than I'll probably ever need on watts/mile, watts used, amp hours used. Found out I used 302 watts on today's ride, of 12 miles, an average of about 25 watts/mile. All to haul home an 80# bag of Sacrete, four 10# tubs of hydraulic cement and a 10 foot length of 4" perforated drain tile and a connector hub, which were of negligable weight. Trailer wasn't happy with the load, but no tires popped. Found out that it couldn't calculate regen capacity of my solar panels because the solar recharge did not go through the external shunt, instead the MPPT controller feeds into the same leads that the battery charger uses. At least, that's what I figured, so hopefully, someone with more experience than I will tell me that I just didn't set up the CA correctly. Thanks to Zev and Justin in Vancouver for a great product!

Me thinks you meant to say 302 watt-hours and 25 watt-hours/mile :)

Yes, that's it. Trying to wrap an old brain around new terms can lead to some interesting results. Thanks!
That is watt-hours (a unit of energy), not watts (an instantaneous measure of power). Energy consumption on a trip is measured in total watt-hours, or watt-hours per mile for an average, not watts.
