Golyo
100 mW
Hello all,
I have a strange problem. When I tested my configuration about a week ago, the throttle worked OK. Now when I am trying to assemble it, it does not.
Parts: S12S controller, S-LCD3 display, Bafang CST motor, 36V battery pack (18650, 31.9Ah).
The original problem was solved. The PAS wasn't working, so P4 had to be changed to 0. However now I am facing a different problem. I don't have a voltage meter on the battery yet, but it feels like the display cuts out at around 40V first. It can be rebooted, but time and again it will cut off again, mostly at full throttle, but the frequency is increasing with the dropping of the voltage. I returned home with 39.1 and 39.3 Volts the last two days. Also the display gets dim. When you reboot it or start it first it is bright as it should be but only for a short moment. It is quite clear that load plays a part with the cutouts, as with no load I can give it full throttle, and it works okay however long I want. The strange thing is that when the battery is charged to about 41.3 (that's the maximum I am seeing) everything looks okay. Does anyone have some good ideas what can cause this?
