    How to know how much battery volts the ebike controller can take?

    If the shunt is soldered with tin, that is going to draw more amps from the battery to the motor correct? But does this modification also draw more voltage to the motor from the battery? Or does it only affect amperege? Also, if I have a controller of 36 volts stated, which is then modified...

    How to know how much battery volts the ebike controller can take?

    Aha ok. How can you see that it is 63 volts by the way?

    Where do you buy your batteries for ebikes for making cheap good batteries of 36-72 volts??

    Ah that is pretty cool. Where do you find those batteries? Those old car batteries I mean. Would be cool to make something with those

    Where do you buy your batteries for ebikes for making cheap good batteries of 36-72 volts??

    Aa nice answers. Are there any good batteries on aliekspress for like 60 dollars and such? Or are they basically crap most of them? I have heard the ampers are often overstated(?) there. They often build them in rows of threes which means they end up pretty weak or something like that(?)...

    IR Camera enough. Or thermal camera necessary?

    Aa ok. Do you have one in mind that is good value for the money paid perhaps? Could buy on aliekspress, but a lot of them are at least 140 dollars.

    What does overvolting mean?

    It is an old 250w hub-motor from Shengyi or something like that. Therefore I look at this as a fun project potentially. If it burns it burns :) Would you go with higher controller and battery but lower(same?) amps? Or could it work just as well, but cheaper, to do some soldering of the...

    What does overvolting mean?

    Aha. So if I run it at the same amps but higher voltage it will not get significantly hotter than before? But If I also raise the amps I could be in trouble? Does it have to be less amps to work? Or could it be the same amps as before only higher voltage?

    How to know how much battery volts the ebike controller can take?

    How do I know how much battery volts the ebike controller can take? I mean how much above the voltage I could go on the battery above the controller's stated voltage? When I open the controller those battery kind of looking things has text on them saying something about 63volt. The text...

    What does overvolting mean?

    Hmm ok. Is it possible to increase torque power and speed by just changing the controller as well? For example if I have a 250w motor. And a 36 volt controller and a 36volt battery.. If I now change ONLY the controller, into a 48V controller., will that controller then pull more power out of...

    What does overvolting mean?

    Hmm ok interesting. Why is it that I see some people using statorade and stuff on youtube to cool the motor if the motor don't really care about it? Is that for some other reason they do that then?

    IR Camera enough. Or thermal camera necessary?

    Aha so you would go with the thermal camera then right?

    Where do you buy your batteries for ebikes for making cheap good batteries of 36-72 volts??

    Where do you buy your batteries for ebikes when you want cheap, but good batteries of 36-72 volts? I live in the European Union so I would appreciate any tips on cheap shipping within Europe. But also Ali and so on from Asia if that is better. I have seen a lot of people talk about...

    IR Camera enough. Or thermal camera necessary?

    Hi I wonder if a simple IR Camera is enough to measure the heat of one's motor? Or is the more expensive thermal camera necessary? Would the IR Camera do a good enough job of measuring the motor temperature? Or is it necessary to buy the more expensive thermal camera?

    What does overvolting mean?

    Hmm ok So overvolting means using a battery that has a higher voltage that what the motor is set for basically? For example using a 48 volt battery for a motor set to 36volt is overvolting?

    What does overvolting mean?

    So I have seen lots of videos and threads about "overvolting". But I don't quite understand what they mean when they say that. I have seen people talk about soldering the shunts of their controllers to make them draw more amps. But this is not the same as overvolting right? This is just making...
