It will not work like this.
You need to generate all CANbus messages from the original Zebra battery control unit or tyhe TIM400 wont work.
Best way is to connect the lithium pack to the old Zebra battery control unit and replace the Zebra thermal resistors with some regular resistors so it thinks its heated.

i just dismental battery and get 3 sensors from battery and its lokk like they are ok. at 20celsius they have around 1.100kohm resistance and it rising when heated. So i think to heat them to 270 and check resistance. Then i will cheat electronics by using propper resistors. In few days i will have BMW li-ion packs to have 240V nominal. Hope it will work
