This cable is used to extend the data cables that run from a Victron Lithium Ion battery to the Battery Management System (BMS). A BMS, or Battery Management System, monitors and manages battery performance, ensuring safety and longevity, so having the right extension cable ensures proper communication and system reliability. The batteries use their data cables to daisy chain from one battery to the next and then both ends of the daisy chain come back to the BMS. Thats why the cables are sold in pairs. The same cable works for both Smart and NG batteries.
