Bosch Active lin-pin outs

Post by beetbocks » Dec 20, 2017 4:56 am

Hi all-
I have inherited a bosch mid drive MTB from my brother but the battery has died-so as i have many lipos lying around from my Eskates builds (and VESC and ESC for that matter)- i'm planning on initially building a 10s lipo pack and 3D printing a housing..(with maybe a complete rebuild and possible BLDC motor transplant in the future -..)
Initially i would like to keep the stock speed controller pcb and pedal sensors etc but i may use a VESC at a later date to delimit the motor
I am however slightly confused as to what the 5 pins are on the bosch power pack .. the 2x larger ones I assume are the main power but what are the 3 smaller ones? are they for the BMS and to turn on the motor pcb?
Any help would be much appreciated.
