Voltage at Maximum Speed

[glacierangel]

How do you find the voltage of a battery pack at maximum speed?
mine is 6 cell
thanks :D

By a device that can measure and record RPM and voltage, like this one:

thanks anyway

Post your exact set-up and someone can guess pretty close. Weight, type and vehicle size and speed and surface is pertinant info. Without any specific info I will guess 6 volts until max speed is reached and then 7 volts if it isn't geared for high speeds. If it's geared for high speed then 6 volts at top speed.

thats a good enough estimation i think. thanks

It'll depend on the pack as well. Some of these new cells are listing 1.2 volts at a 30 amp discharge if I'm not mistaken. I have some old clunkers that go well below 1 volt and even some junkers that go about 1/2 volt . No power from them, lol.

lol
ok
thanks
