I pulled the batteries out of the 2 packs I bought. These are molicell batteries? Are they missing the sleeve that is normally wrapped around them or is there some sort of metal shell over them. It's so easy to short this battery out. Can I clean the old welds off and spot weld onto these?

The metal blades where the battery connects to the robot is what's holding it in. I used a pry bar to pry them down through the slots and then worked it slowly out pry on the corners. I ruined the blades though.

This is wicked! Though it's pretty expensive. I was looking at this one and it seems like a good option. I did not realize that QS Motor sells the 205 with an option for 175mm dropout. I think I can put a 5 or 7 speed freewheel on it, though he claimed in the email that he has not heard of...

The reason for the fat bike frame is simply this, I want a 7 speed freewheel on a QS 205. As for the tires, I have no comment because I have never used 4" fat tires. The plan is to try 4" tires first, but the rear rim that I am lacing to the motor will be 65mm so I can fit smaller sizes if I...

This will be my 4th bike frame. List of major components: -Fucare Taurus frame and front fork (26" fat bike) (have this) -3shul C350 V4 controller (have this) -QS 205 4T Motor with the 175mm axle (waiting on this) -Home made battery - 72v 30ah (20s7p) using molicel p42a cells (waiting on...

Thank you for the reply, what is the best way to talk to somebody about buying this motor? I sent an email to your address but have not yet seen a reply. Also, is the QS 260 also available with a 175mm dropout?

Hey guys, I've been looking for a motor to put on a fat bike frame with 190mm rear dropout. It seems that NBPower sells one on AliExpress, they replied to my email claiming the 5000w motor is 50H, can produce 120nm of torque, and the 3T version has a kv of 11.9, 4T version has a kv of 10.5...

@QSMOTOR Do you have anything currently that will fit a fat bike with a 170mm or 190mm dropout?

https://ebikes.ca/blog/post/45mm-fat-deposits.html What do you guys think about this motor? 45mm magnets, 205 or 212 rotor diameter (not sure which). Maybe it will be rated around 2000 watt? In the motor simulator, it might be comparable to the XOFO DD45. I have the QS 205 on my fat bike...

Following up on this, I used M3 washers to keep the spoke heads from slipping out of the flange holes. Wheel works great on the regular 13/14ga spokes, though I want to try and put a 7 speed freewheel on this motor. It's only meant to have a single speed, so i need to also put a spacer on...

Hello guys, I got my hands on the QS 205 hub motor, and the flange holes for the spokes are 4.2mm in diameter. I want to build it into a 700c wheel, my ideal tire size is about 700 X 47c. I am going to build it using the Sapim single butted 13/14ga spokes bought from ebikes.ca, I already have...

EDITED: An update. The answer is no, the Kelly KLS motor controllers are not torque based controllers. When throttle is applied, the controller appears to map that throttle input to a desired wheel speed and not a desired torque. There does not seem to be an option to change this. I read...

You can use the motor calculator to find out what Inanek mentioned, but instead of using thier preset motor controller options, select a custom contoller instead. Then set the controllers phase amps (90 for phaserunner, 70 or baserunner), and heres the key part, set the battery amps to whatever...

Hey I read that article and thats awesome that you got it working. I had the same problem with my front motor cutting out at a faster speed. It was interesting because my motor would start to hum and make a weird sound just before the controller faulted out. I learned that this problem is...

Hi amberwolf, thank you for the helpful links. I have a pair of front and rear ezee geared hub motors bought from ebikes.ca about 6 months ago, I'm not sure how many amps those motors are rated for. I have the pole pairs set to 80 and did run the autotune process for the phaserunner, then...
