the can messages are identified with an id, like 0x031,0x032 ... etc. if you have more than 1 bms, you need that every bms has differentes id, just ask to the guys of rec-bms, and they will change the id of the messages with differents one, like bms 1= can message=031, bms2 = can message...
i will use the rec-bms
Works fine, and communicates via CAN, that makes easy to me to connected to my raspberry pi system.
Now I have 14 cells with 1 bms, next week i will add another bms to control the 2nd pack of 14.
www.rec-bms.com this guys are very helpful and have an amazing tech support.
@nexsupene101 the node.js script reads the serial port connected to the PIP and send data to influxdb
In the last 3 days i made a progress...
I connected my REC-BMS , to the raspberry pi3 using a PICAN2 board, (all in the same raspberry pi3)...
I will share the information about my installation.
Raspberry pi 3
serial to ttl
Raspbian as operating system
influxdb as database
grafana as visualization

understood, now i understand how the batrium bms works, it' burn the excess of energy in each to cell to top balance them.
I was thinking that the balance is sending current to low cells to top balance, but now i see how it works.
All the question are answered.
So basically :
also i understand that there's is wires (slave, longmon) to every positive battery, in my case 14.
the batrium is connected to the common negative?
the batrium is connected to the common possitive?
How balance the batrium the cells, sending current to...
I have a pip4048MS , i'm duplicating the @hbpowerwall configuration, now i want to add a BMS, probably Batrium, but how it's connected the BMS if the same 2 wires are using to charge/discharge the battery??
Can some one made a little diagram to help me?, i don't know how to connect a BMS...
