Dear Support,

i did already a successfull learning with this gauge with a 3500mAh 4S battery pack.

Now i had to switch to a different battery. I found the dedicated ChemID in your list and took the Program Data export of the previous 3500mAh and modifyed it to the new 4800mAh parameters.

- I flashed the Firmware R5 from your homepage onto the gauge.

- Uploaded the proper ChemID

- Setted up the Program Data properly

- Calibrated the Cell, Batt, Pack voltages and current

Started the learning cycle. Now im at update status 04. i started the charging cycle from the discharged REST status. No protectionlimit was triggered.

At the end of the charge the taper values (current and voltage) were met. The flag VCT went into '1'. After time the VOK bit cleared, REST changed to '1' FC was set but the QMax flag remained 0 and the update status didn't went int 05.

Can you please take a look on my log data what went wrong?
Also attaching the program data with the settings.

Many thanks!
