Some battery questions

[urastus]

I have a shimano system - e8000 with 504wh battery. I was wondering if these use a passive or active bms? Also, does anyone know the best charging routine for a battery pack (made up of 18650 cells) with a passive bms - it's in an e unicycle.

OK, did some research and found my answer re passive bms li-Ion battery systems and charging. I don't know how relevant this is to our e bike systems. It does answer my e unicycle question.
