Re: Trying to find a battery for my ebike

I recently got this bike that is just missing a battery. Where was it purchased? Knowing that, the purchaser can be asked what battery it was used with originally, which may help you determine what it can be sued with now. I want to be able to ride for 20-30 miles in a pretty hilly area and am will...

Re: Sempu T2.3 torque sensor - missing part

Is it just a flat ring? Or does it have a specific shape? If it is just a ring, you can make your own out of a sheet of plastic of the correct thickness, as it is just a spacer, based on whatever it shows in the videos and such. If it has a specific shape, you could probably also still make your own...

Re: Baserunner on off switch issues. (Phaserunner)

Presumably this adapter cable came from Grin Tech with the BR. If so, they should have the wiring diagram for the cable available so you can replicate whatever portion of it you wish. Otherwise, you will need to measure the pins on each end of the cable to see which ones are internally shorted, so y...

Re: 48V500W Rear Driving BikeConversion Kit

I assume the cells are ok While this is likely based on the previous posts in the thread, you should still measure between each of the wires from cells to BMS, to ensure they are all about the same voltage, and none of them are too high or too low.

Re: Torque sensor not working in Bafang setup

I just noted that the new sensor needs input of 8-12V while the old seems to use 5V... So this might be the main reason for my problems. Yes, if the new sensor's supply voltage is not the same as the old, you'll need something that supplies that for it. You can get a DC-DC cheaply that converts you...

Re: Rad Power hub motor bearing replacement

So expecting a 40A phase current from a 12-15A capable battery supp...

There are a number of types of torque sensor, and several types of output.

Some use a digital signal, and that can be in several possible forms and formats....

Re: Rad Power hub motor bearing replacement

That "9-Pin connector and comes on most every low to mid power capable motor" is good for up to 40A? That would be almost 2,000 watts. 40A on the phase wires is different than 40A at the battery, so you can't measure the power that way. You can have a 9 or 10A battery current and still get 40A phas...
