Found another SMBus application note, this time from texas instruments.
The BMS IC i'm trying to communicate with was made by them, so if anyone is to tell me how to do it, it's them, right?
And according to their diagrams my communications are correct also.
Although there is a small mistake on part of TI, see if you can spot it.
Not sure then why i'm getting wrong data. Perhaps i should try another battery pack?
