Hi there,
I have been porting the library to ESP-IDF and I have many found plenty of inconsistencies regarding the flash subclass IDs, offsets and values read?
For instance

readFlash(48, 24);
chgFlashPair(21, designCap);
chgFlashPair(23, designEnergy);
chgFlashPair(28, CellVT1T2); //0x0E10 = 3600
chgFlashPair(30, CellVT2T3); //0x0E10 = 3600

In Flash Subclass 48 with Offset 21 there is Cell Charge Votlage T3-T4. Design Cap is actually on Subclass 48 with Offset 11.

Which DataSheet Version have you followed?

Also, could you please explain why you are reading the flash with offset 24 while you start changing values starting from 21?

Did you figure this out? I'm wondering about the same questions and don't understand why the Offsets are different to the Offsets in the Datasheet. And also why a higher Offset is used in the "readFlash" command.

Most likely things have changed in the G1's later firmware.
The G1 was launched just at the end of when I last looked at this iirc.
This hasn't been used since March 2016
