Well over the weekend I broke down both batteries(13s5p) and put them both together into an 13s10p pack and was able to get everything into the triangle case I made but they barely fit. Pretty happy with my results.
My commute to work one way is 4.7 miles and I usually go pretty much full blast on the throttle. Usually about 60% of the way there (and over the only two hills in this commute; bridge over a bayou and bridge over railroad tracks, very steep) I'd notice on my display I get to 3/4 of battery and stay there until I reached work then returning to home I'd be at half. Well since I did the battery over the weekend (charged to full on Friday then broke them down and put them together, finished on Sunday no recharge) rode about a mile or so Sunday just to test, rode to work this morning 6.3 miles at work and all had all 4 bars. Right at 8 miles on the return this afternoon dropped down to 3/4, needed to go to Wal-Mart and return home 13.6 miles and dropped down to 1/2 way mark in my driveway but had considerable stop and go on the second half of my journey today and as always pretty much all full throttle. Reads 49.3v right now. Going to leave it off the charger tonight to try and see what my real range is for a good charge.
I'm by no means at all a knowledgeable bicyclist and over the weekend I changed out new v brakes (complete; cables, arms, pads, everything) and switched over to finger shifters from grip shifters (handlebars were crowded with twist throttle and grip shifters). Went pretty smoothly as I've already adjusted everything before i converted to electric when i got it out of storage.
But since combining the batteries it doesn't seem quite the same. Feels like it takes a little longer to get up to good speed (I always pedal and can feel when the motor overpowers me pedaling at about 17mph). Should this be expected? I know I added more weight but in the grand scheme of things (this was a pretty heavy bike after the conversion and I'm 185 lbs) I didn't think it would have been as noticeable.
Going to double check everything tonight and make sure nothing is dragging, it really doesn't feel like mechanical drag. Also trying to figure out some more about tire inflation, this whole time I've been riding at around 35 psi and have felt like every other day the tires feel a little flat and top them off to 35 but today before the store I did that and noticed the tire says 60-90 psi on the tire that came on my electric hub rim kit. Felt better at 40 but don't know how far to go with these slime filled tubes. Any advice on solid tires with heavy ebikes?
Hit 600 miles today. Wohoo
