I need to custom setting the absorption and float voltage of my phoenix multi plus 12 300 120 firmware 190911..hex
I downloaded victron connect and plugged in my laptop with an MK3 interface.
I now have this message from the app: firmware version not supported, use VE flash to update to 200 version or up.
From what I am reading not an easy operation and I cannot fail since I am sailing.
Is there any way to change my settings without playing with the firmware?
Thanks for help.
