I have a 36volt brushed hubwheel project will more volts / batteries give me a faster speed? ??
Also appreciate any advice tips on the subject as I'm new to the ebike builds...thanks for your help alan

You may be able to find the answer to your question here Difference between 36 and 48 volt batteries. Look at the second post. I would have thought the motors were voltage specific but this answer says it is not so. Note it does say your controller may not work on a higher voltage.

All other things being equal, more volts will give you more power. Power in Watts = Volts X current in Amps. More volts, more watts. However, from my electronics experience, not all electronics work on higher voltages and you run the risk of burning them out. Plus you have to make sure the motor can handle the higher voltage as well, since with higher voltage you run the risk of burning a motor out too. With higher voltage, you have a higher current running through your circuit, and you have to make sure your circuit can handle it.

I wouldn't trust that. I've seen electric motors rated at specific voltages and wouldn't want to drive them any harder than what they're rated for. Simple Ohm's law tells you that higher voltage = more current, and current is what burns out electrical/electronic circuits. One or two extra volts may not do much, but going from 12 to 36V might cause problems.

for the motors themselves, current is the main concern. You generally can run a motor on much higher voltage than the nominal voltage rating. Higher voltage does give more room for speed, but on a brushless motor, the controller is in charge.

There's an entire subforum for this here.

You want to go faster--ride more often and harder.

Marcus not so easy when you are near 50 year old and have a serious copd condition....
And I love biking done it as my mode of travel locally since a kid it's just that I need a bit of ebike help, with my condition and also from the forum, if possible. ..
And not remarks like yours thanks. ...

Also I'm new to the forum scene so I will thank the above posts from here.
all information is well appreciated and stored in the memory banks...cheers. .

Thanks for your help and information.appreciated. ..Alan. .
