It's examples I was looking for yes. To get a benchmark. I'm having trouble finding one. I will take your two examples to explain why I'm struggling, then perhaps you can put me right.
The write up I found on the RM was duel motor, with no figures for single motor use. The Giant is also a two motor design, not reviewed as single motor. I don't know the wheel size used (looks 26") or the motors voltage, but it spins faster than any of the 4 I know of. That's if my math is right on the last page.
I would really like to see a bike with 26" wheels and a q100 motor of any sort where it's named and so is the battery voltage and controller type/spec. Some meaningful data like speeds on gradients would be bang on, but a top speed would be something I could take onboard. Just the kind of review you would expect. I need a proper motor ID/voltage used/controller/wheel size/ results. If any one detail is missing, I can't use any of the data.
I have been looking at
the 201 rpm 36v 500w Bafang BPM motor and 48v 15aH battery or 500w Bafang CST motors with 36v 20aH
you spoke of. I read over and over that there the same motor. Even from yourself a few months ago. Why the different battery recommendations? I did hear they are different motors somewhere, as the cst got further development. I can't see it now though, and it makes no sense to mod one, but not the other. I'm left a little mystified.
I can't seem to find the mac/bmc motor's for sale. I like the look of the bmc v2 spd and 20amps. The one on the ebikes sim. I can't get on there site though, every link is there policy's page, and there search a javascript error. The cheaper mac now has the better gears, but I can't find either anywhere. If I could get a mac to offer me a spd version that might be tempting. I'm just tiring now though. About to order the hobby king cells and a 3v-4.2v bms, with a q100 kit from bms battery. The bms is only £20, but I'm unsure about specifying 3v lvc as It will be under some load when I hit the lvc, I don't want to be switching off sagging batteries that still have some left to go. I have read some long threads that tell me nothing. Maybe 2.7v lvc is better as off load they would come back up. To something. But I'm not seeing it discussed. The hvc is also up in the air. I see 4.2 is reasonable, but 4.1 and they last longer. Less capacity, but just what is stated between 10% and 30%. I can live with 10% but 30% is not acceptable. So 4.2v is it.
I don't know If the bms is the regulation for charging in the normal sense. Say I have my 12c set for 4.2 per cell, 50.4v pack. Do I use a psu of say 60v and the bms sorts it out, or do I actually need a psu that gives out a fraction under 50.4v. This is my next avenue of investigation.
Thank you again for your time.
p.s I can't join pedelecs. Banned!? very odd..
I noticed your modding throttles to run two controllers. Adding both beads to one unit. Can't you share the throttles 0-5v control wire between a few controllers? If the 5v means nothing to the second controller(that didn't power the throttle) then you may need to tie the grounds of each controllers throttle power source. Just a little food for thought. If it did work, you could add a duel track trimmer, using a track at each controller input to balance the front/back power ratio on the fly. It could be worth a good look, if you have not done so already.
Edit: They might not balance well, as if they can't supply the full 5v, they are never going to stop
