First I am not asking about DIY cables.
I am asking about the standard LAN RJ45 cable that one can buy in any computer store.
Why the Victron made cable so expensive?
In my country, the 0.3m Victron made (blue) cable cost over $10.
The standard CAT 5E 0.5m cable in computer store costs 60 cents.
What is so different in those "blue" cables.
