That price is incredible low ! Did not figure out shipping cost though.
I paid between $ 45-$50 with shipping cost for the kT that I got.
I do see the advantage of such a cheep and smaller controller, .... if it works as well as a $ 60 ( before shipping ) one,
I see that it, just like mine is limited to only 14 amps, ( mine says 14 amps +/- 1 amp )
I have the 201 rpm speed Q100c CST as well, and the controller is 48 volt.
I want to get the best hill climbing performance out of that Q100c CST motor that I can, since I live in an area with Mountains all around me.
you are running your Q100 H motor at 17 amps, is that at 48 volts ? Have you Run a Regular Q100 ( non H ) at Higher Amps Continuously at 48 volts ?
Have you taken a KT Controller that is 14 amp max
Done a Shunt Modification ?
I see the Shunt at the end of the controller, and from a past post from John in CR, from 2011, he shows how to do it better,
https://endless-sphere.com/forums/viewt ... =2&t=31643
by wrapping some small guage copper around it .
How many wraps ( number of wires ) , and of what guage would bring it up to around 17 amps ? ( if you have done this to a small 14 amp controller )
Is there a way to then measure current with a simple volt meter ? to see the before and during and after modification , in order to get it right, meaning not too many amps.
Link to a small meter , that would measure it ? ( I would hook the meter up to the shunt with alligator clips ?, or is there / place to connect a display/meter to measure it? Anyone done a shunt mod of just a couple of amps ?
Bigmoose has a different way of doing it, but it seems much more likely to mess something up.
the simple method of wrapping some thin copper wire around the shunt , for simplicity sake is the way I would do it.
