Hi,
I have a converted Audi A2 with a 100V Lifepo4 battery in 30s2p configuration (50Ah cells). It is equipped with an Actia Master and 6 Slaves. Since the Cells are very old and degraded I would like to change them out against 100Ah cells. Therefor I would have to reconfigure the BMS from 60cells to 30 and ofcourse the rest of it. Unfortunately I would need a Password for the web server of the BMS and Actia doesn‘t support the BMS anymore (you could buy access a few years ago). Is there any way to access the web server or is it impossible to save the otherwise complete useable BMS?
Any advice is appreciated!
Karl

Sorry, but does anyone happen to know if there’s a way to reset the BMS password through a hardware method, or if there are specific diagnostic tools that might allow you to bypass the web server access?

Hey karl,
please try 854893 for Level3 Access.
You type it in over the Webbrowser.
If that doesn't work i can supply a flash firmware that is made with Webbrowser support for Parameter changement. It was designed for the 30s NMC Battery for the Fiat 500 Karabag.

Hi,
