What I really want is something that can be added right at the connection point of the busbar where the lug attaches to the busbar. Compact form function helps...something similar to a "fusible link" type thing but not cheap junk and rated for 50-60v. I like the little fuses that victron uses in their battery but want something that can retrofit into a conventional battery busbar. I appreciate any suggestions! Thank you in advance!
