SOC memory Lynx BMS

I was wondering why there is no option to put the SOC in the memory on the lynx smart BMS series.
Every time you shut off the BMS the SOC is lost. I know the BMV series has an option to memorize it.

I know this does not help but the NG version of the Lynx BMS has configurable SOC. Therefore bringing it to the older version may be more than firmware mods as the firmware development paths are similar.

That is also possible with the old one. But yeah that doesn’t help.
