I am interested in buying an electric bike that has 2 batteries that opperate at 12v @ 10 amp hours. They are designed to work together to deliver 24v to a 450 watt (peak) motor at the front wheel. Unfortunately these are heavy SLA batteries, and I would like to replace them with state of the art Nanophosphate Litihium Ion batteries.
Now the kicker: I can only find 36v versions for use in DeWalt power tools (though they are very energy dense).
So what I am wondering is if I can buy 2 / 4 of these and wire them to deliver no more than 36v continuous to the 24v motor and will it improve performance or just burn up the components.
Also as an added question, if it is not possible to run 36 volts directly is there a controller that could accomplish this.
Thanks!
The motor is from Currie Technologies, specialists in electric bikes.
I should add that the motor is DC as will be the current delivered to it.
Answer
Just replacing the 24V pair of batteries with a 36V group will very likely cause something to fail. It is possible that a controller could be designed to allow a 36V group of batteries to work with the motor, but it isn't something that you are likely to be able to easily find and mate up to the existing motor.
Additional information:
If you get a 36V PWM controller and set the current limit to the maximum continuous rating of the motor, that might keep you out of trouble. If the motor has a higher short-time current rating that you want to utilize, that might be difficult to set up.

It looks to me like Currie Technologies offers some models with a 3X12V 36V battery package, 36V controller and 450W motor.

How do I rig a corded electric motor to run off a battery?
Chew
Basically I want to take a corded electric motor and slap it on my bike.
The motor I have is
120 volts
12 amps
1440 watts
and it's DC making it convenient for batteries.
I was wondering how I would go about or what I should look into to powering this corded motor with a battery to make it mobile.
Answer
I think you need to recheck the motor. If by corded, you mean something you plug into the wall then it's AC. If it's 120 volts then it's likely to be 120 Volts AC. DC motors tend to be 12 Volts, 24 Volts, 36 Volts, 48 Volts, or 96 Volts. Besides it would take a lot of batteries to get 120 Volts DC.
