Hi All,
My homemade e-Bike 36 volt battery is about dead but I have a 48volt Li-On that I'd like to replace it with.
The bike's DC-DC converter and motor are sized for 36volts.
My question is what Power wattage of resistors do I get to create a voltage divider to power the 36 volt input of the DC-DC converter?
My assumption for R1 / R2 would be a simple R1=250 ohm, R2 = 750 ohm.
Both batteries are 10amps. The load is variable with motor speed but my assumption is the motor could draw up to or near the battery current capacity of 10 worst case.
Thanks for any / all help. Also, any suggestions of where to purchase these large resistors would appreciated.
Thanks!
