AVG on V4.4 with V4 controller / high speed communication

hello Community,
i will update my DIYBMS modules V4.4 to the AVG function. is this possible with the V4 controller?
the voltage on the screen is going up and down with ± 0,004V. sometimes ±0,008. the voltage is absolute stabil, when i messure with my fluke 179.

in the video made by stuart he shows the new code wih ±0,001V
now i have the code 47fe99bc at all my modules. is this the last version?

thanks for help
