Cyrix-Li-CT input cable hot

I've been using a Cyrix-Li-Ct between my alternator/battery terminal and 3x200amp hour Victron SuperPack batteries. Tonight I noticed that the input into the Cyrix was very hot. 1/0 cable runs approx 20 ft from the vehicle battery to a 120amp fuse then about a foot to the Cyrix then another foot of 1/0 cable to the bus bar which connects to the lithium batteries. I was running the vehicle charge the batteries and the system was showing approx 56amps going into the batteries.

I have been using this configuration for several years but tonight the connection between the fuse and the Cyrix is hot. Thoughts?

Maybe check/remake the connection between fuse and Cyrix. Could be loose/have some corrosion. Heat could be coming from the fuse/holder as well.

Thank you...I discovered it last night so planning on replacing the cable this morning.

Replaced the cable but the fuse popped again. Next stop is the fuse. Don't think its the Cyrix since it was working until fuse popped.
