I'd really appreciate some advice - completely new to this so apologies if silly question.
I see Victron recommend 70 mm2 cable and a 300amp meg fuse to the Multiplus 12|2000.
I have a 230amp lithium battery (obviously less than 300...)
should I go for a smaller fuse in this case? and what wire size? if length of cable relevant, definitely <5m, probable around 1m
