Using the INA226 to measure current up to 80A from 42V battery

MikeLemon:
Hello,

I'd like to use the INA226:

datasheet:

http://www.ti.com/lit/ds/symlink/ina226.pdf

along with a 10 milli Ohm shunt resistor and a current of upto 80A in order to monitor the high current off from my battery now in the data sheet it says "Senses Bus Voltages From 0 V to 36 V"

what is the meaning of that?
Can I measure the high current from the 10mOhm Shunt resistor with that ic (max 0.8V voltage drop on the shunt)?

or that would mean that I could measure a current of upto 3600A with that 10mOhm resistor?

Another question that comes with that after a little bit of research. Is it necessary to connect V-Bus say of the battery to the INA226?
