I got both motors working off the greentime controller with the throttle.
Theoretically it should be 17.5 amps to each motor but when I get into the throttle I hear a rumbling noise. Not sure. The motors might be getting too much power. Not sure.

They are not under load and supposed to be 36 volt motors. You can't hear it in the video but I heard it. Kind of a low rumbling noise. I don't hear it at low throttle though.
Let me know what you think when you watch the video.
I would like to try the bike out. I already installed the motors. I have to mount the controller.
That is the only controller that would work. I do not want to order another Greentime controller as it takes way too long to get here.
Looks like less than 40 pounds with both motors. I knew the Outlook was a lightweight. Easy to carry up and down the stairs. I want to keep both motors on that bike and order a new front hub motor for the Currie.
I am not hooking the controller up permanently yet.
I just ordered a 12 amp 350 watt controller from Amazon and a 3 wire thumb throttle. Looks like a month before delivery. April 19 to May 10.
I need to finish the 10S pack. The BMS is 16 amps so might keep the motors from burning out but then they will both only get 8 amps, That is not enough power.
They could be getting too much power with the 35 amp controller even though it is running both motors. Not sure.
I really wanted one of those motors on the front of the Currie though. If I were to hook up a smaller 10S pack to the 35 amp controller then the controller would not be able to draw as much current right ?
They are all in parallel and all were bought in 2020 I think. It may have been 2019 but are way newer than the old packs. If I were to split them up I could hook up one 4.4 Ah 158 Wh pack to the 35 amp controller. The BMS in the pack should limit the current so I do not burn out the motor right ?
Once the new 12 amp controller shows up in a month I could hook that up to the Currie and run both 158 Wh packs in parallel and use the Greentime 35 amp controller on the DimondBack outlook with the 10S - 6P - 16 amp pack I am building. I can order two more Bafang motors so can have two on the Dimond Back Outlook and one on the Currie plus a spare motor.
That is the specs on a 4.4 Ah pack on e bay. Not the specs for my 4.4 Ah packs but should be similar specs.
That really don't make any sense. It says 158.4 watts but if the discharge is 20 amps * 36V = 720 watts ? I really don't get it.
Please let me know.
Thanks.
