Sorry if this has been asked before. I can't find it in a search.
I have a 48v direct drive ebike that I just built. I put in 2 10,000mah 6s lipos in series with Anderson Powerpoles - Equals a 12s lipo @ 10k.
My voltage when I start out is 50.43. The kit specs show I should be able to go somewhere between 18 and 25 miles without pedaling.
I am guessing that the controllers low voltage cut-off is probably 42 volts. There are no specs on this in the kit.
When riding only about 2 miles my cheapo 4 light LED display goes from 4 lights to 1 light, even when I let up on the throttle. My voltage at that point is about 47.8. I am just doing test trips, but one trip my throttle cut off not too long after the LED went to one light.
My controller gets warm, but not hot. It is 26 amps.
I have checked for brake drags, etc. The wheels turn freely when raised up.
Question(s): Are the LED power meters this inaccurate? Is this a controller problem? Is there a way to change the LVC - It appears mine must be about 47v?
Thanks for any help!
My kit is similar to this one, except I have the 700c wheel.
