I bought a H7 battery today, I currently have H6. I'm using Forscan (to make changes) for my first time tomorrow, just aligning my ducks. It seems that the attached picture shows I will have an 01 as battery type, and I will want to change to 02. My question, and excuse my ignorance, do I change that where the ** are shown or the zz
I've been watching videos, have Forscan installed with extended license, and my EX link ready to go

Yes you do. The line should read 726-04-01 02xx xxxx xx for an H7 (the "x" places don't change). When you make the change and select the 'Write' button, you will get this error message:
The last two characters in the line are a Checksum. By selecting the 'Yes' button, you allow FORScan to enter the correct Checksum value and complete the Write command. Then Reboot the module.
Just an update for any future user, easy peasey. You actually don't even need to go into the BdyCm module configuration (as built files), simple select the other one; not the 'as built files'. Forscan has all this preloaded for dummies like me. Easy to select battery size, select new option. Same place as you do the BMS reset. (I did verify by going into the 'as built files', everything changed as it should.
