Unanswered Shimano Battery pinouts?

[StephanT]

hi

Apologies if this is in the incorrect section - but didn't think it needed to go under motor...

I've looked through the Shimano PDFs as far as I could find them... but couldn't find the answer.. does anyone know what the pins are and which is which - naturally we can assume that the two big ones will be power (+) and (-) and polarity can be measured pretty easily.. but what are the other 2 ? (E-tube comms?)

pos at the top and neg at the bottom ( asper the markings on the plug!)

The other two are low voltage circuit for the controller.

Ahh, so the battery makes the low voltage and not the motor itself - I would have just taken the battery voltage to the Motor and have its electronics sort out the required low voltage (less copper - less weight - less complexity (sortof) )

but thanks for the info!

And I guess that means there is no comms between the battery and the motor...?
