Hi All,
I already installed the EM200+QS138 midmotor to my JDM Titane moped car, with 18S batteries (from BMW i3).
I can say it is more than enough, it has a very good acceleration and around 80km/h maximum speed.
I replaced the belt pulley on the motor to a bigger and wider one (24T HTD-8M, 30mm wide) with and Omega HP belt.
The final drive ratio is 5.8 : 1.
This controller isn't bad, but it was hard to set up everything with this chinglish manual....
I have few questions, maybe somebody else had the same:
1,
I tried to setup a lower amp for the normal use, but the "BUSBAR CURRENT" field doesn't make anything. The sport mode is off (i checked in the "display menu", but it gets the current limit from the "sport mode" settings.
Finally i adjusted the % values in the "LOW, MID" sections on page2, and it lowered the amps (at the percentage of the sport setting). If i activate the sport mode input it overrides it. Is it normal? What is the purpose of the "busbar setting"?
2, What is the purpose of the 2 columns in the "Three speed" settings?
Edit: I found it, the left column is the speed reduction (%), the right column is the Current reduction (in the % of the Sport setting)
