The IBS is not something you can change the software revision on... The IBS just sends voltage data to the DME. It's not a control module per say.

I don't think you'd need to re-register the battery. The battery data should be in the CAS or DME. In fact, I wouldn't re-register the battery because then you'd be telling the car you have a new one when in fact you don't.

Coding for battery type should not be affected in any way.
