Re: Looking for ebike professional in the UK.

Then you need to either sell the current controller you already have and buy a controller with a temperature sensor, or convert the controller you have. I dont keep up on Sabvoton controllers, but you sure you can convert a non temp sens cont to a temp sens? If that be the case, then someone needs t...

So would it be correct to say that when my ca says 68 max amps, that means there was 68 battery amps?

Check out the new 2-ply Schwalbe Pick-Up, similar to the Kenda Kwick Drumlin Cargo but I'd obviously trust Schwalbe over Kenda, and it's available in 27.5".
Rated 5/6 for road grip and 6/6 for protection.

Temp sensor wire in the motor is easy to do.

*Be sure you have the right thermistor for your controller.

I'd try to layer each 0.12 pure nickel strip or 0.15 nickel plated steel strip
welding each layer onto the next

or solder on some solid core wiring onto the strips.

I think a QS205 has 50mm magnets
The QS205 has many different heights of magnets with lots of difference wattage ratings.
55H/50H/45H from 1500W - 4000W there might be one listed as 5000W.

Re: new eZip motor

Those high power brushless chain drives are like bucking broncos unless I get a really expensive programable controller. Even with a cheap generic controller the big power motors are pretty good, so not sure where you get the bucking bronco idea from. Its better to have a single powerful hub motor ...

Re: new eZip motor

I like more charge amps, but I also look at the C-rate for charging. My laptop chargers were 5S (19V) in reality 20.50V so 0.50V off max charge, but at 8A. To add to that I had two batteries both 5S that I put in series with a home made XT90 series harness so I could disconnect 10S into 2x5S, and us...

Caused by government allowing the standard diet to happen and government being paid off by corporate lobbyists. Another interesting fact, when time changes occur and people lose an hour of sleep there are more car crashes and hospital stays. 25% more. And when people gain an hour, its 25% less one s...

Re: DC Step Down

Its short circuited

Remaining battery voltages is very hard to measure, then you pu tinto the mix cheap displays.

Display is erratic, thats why you take a digital multi meter and measure to confirm 0V.

Soldering does take skill but theres no magic to it, only thing is it just takes practice and a little bit of technique.
