I posted this on the Bafang group page and for some reason it wasn't allowed.
I'll have to swap out parts to narrow it down, my thoughts are electrical rather than mechanical:
Bafang Max (M400) Problem- Anyone have experience with these (or maybe the BBS does similar)? Mine seems to be getting a 'stutter' coming from the motor under load/ uphill and it seems to be when the battery is low (though iv'e only run through 3 battery cycles so far). It feels like it's a 'skipping teeth' type thing but no real noise, just feel it through the pedals and it looses drive. It's got me a bit baffled as i'm not sure if it's electrical (controller) or mechanical ((pawls) or the battery cells are tripping something when low? It's anything from a momentary loss of power to stuttering for half a turn of the crank then comes good. I'm sure I can work it out but considered also that the low power could also affect sensors etc (no error on the display). I'm not really sure where to start, some components are expensive for these.
I know this is a 'closed system' motor, not so popular here but any thoughts welcome?
