In reading the manuals for inverter /chargers, it isn't clear whether the lengths in the table is one way or total cable length,
Also the Victron toolkit, the cable length automatically calculates return cable lengths as per

This is in

0-5 m cable length: 4 x 50SQmm 5-10 m cable length: 4 x 95SQmm Cable length stands for the distance between the battery connections and the Quattro connections !!! Recommendations are without other loads in the system and these also should be taken into account for proper main battery, main fuse & main switch cables !!!
I read that statement as a one way distance, it would be helpful if the manual was a little clearer in this respect. a 2.5 M run from battery post to inverter is very challenging in a marine installation... so I am just wanting some clarifications on these recommendations
