SMBus default Baudrate and Address
SMBus is derived from I2C and, therefore, is a synchronous protocol with its own clock signal. Therefore, any bit rate, within the allowed range, will work and can even change from bit to bit. Thus, there is no need for a defined bit rate.

SMBus v 2.0 adds dynamic addressing to I2C but you say that it uses v1.1. However, the specification gives a fixed address for smart batteries: 0001 011. This is probably what you need to use.

Here is an NXP app note that talks about SMBus and discusses these issues: nxp.com
