Hi all,
My noisy, whiny, slow-ramping 23a ku93 9 fet controller, isn't quite powerful enough on throttle only to get my Bafang CST 250w (180mm) up some local hills, and I was wondering if the sine wave s12s with 12 mosfets would be any better. The s12s used to be 23a apparently but now it's 25a +/- 1a. Am I just pouring money down the toilet here,ie is there any improvement in power to be had from the s12s, or will the motor only be able to use 22a as some have said, and the extra amps be wasted, shortening my range, (and perhaps generating harmful heat)?
Is there another controller which will get more out of the CST 250w, or am I really looking at another hub motor? I'm considering going over the legal 250w nominal, to allow me to use a bike freely despite my knee problems, although am worried because I hope to qualify as a lawyer at some point in the near future, and any criminal convictions could prevent that. If another motor is the only answer, would anybody have any recommendations please?
Thanks
Edit - using a 36v battery, 14.5ah 10s x 5 Samsung ICR18650 29E LiNiMnCoO2 cells (3.7V 2.9Ah).
