I did a successful conversion to a 18650 batterypack 36P36S and now I am planning to buy a new Zeva EVMS Lite V2 with 3 Zeva 12S BMS module(Including EVMS monitor).
In the comments from Zeva there is a particular question of which one of you maybe knows the answer.
Here is a quote: "You can integrate our BMS with an existing CAN bus, but the bus speeds have to match. I think the Vectrix is 250kbps? (We would have to confirm. By default our devices use 125kbps, but can be supplied with different CAN speeds.)
