Hi All - Well, I have made about 75 34-mile round trips to town. I have been charging in town, with the batteries at about 50%, and again at home. It usually takes 1.3 to 1.4 kw to recharge after the in-trip. (On a meter.) No meter at home, but I would guess 1.6 to 1.7 after the uphill run. Therefore, these batts have about 150 charge cycles on them. In the last two trips, I am fine downhill into town. Coming home uphill, however, the last two miles send the onboard meter down to the red and my speed is limited to about 30 mph.
I was expecting 300 or more charge cycles. I suppose it is possible I have a loose battery connection somewhere after this many miles of bumping along.
I only need about 20 more trips this season, and I really don't want to tear into it until I knock off altogether for the winter. Any ideas or experience with battery longevity or refreshment appreciated!
