Hi all, just finished building my 280ah battery. Can somone till me if I need a fuse on the 35mm positive wire (green arrow on picture) that goes to the positive stud on the outside of the box? View attachment 25770
I have a isolation switch Between the positive stud and the fuse box, would that be the same as your suggestion?A breaker would provide a nice way to disconnect for servicing.

The closer to the battery terminal the less chance for a short upstream.
If that wire fell off the inside of the proxy terminal it could make for a very bad day.
But... if you look at the videos where Will Prowse cuts apart the drop in replacements, I don't think any of them had a fuse between the battery terminal and the proxy terminal.
Whichever way you go loctite is probably a good idea.
Let me reprhase : "It is adviseable to have a fuse at the battery terminal" . I find it easier to locate the fuse at the battery terminal - nice solid connection with all the good products out there and it will protect even that short piece of cable running inside the box should something go wrong.I don't think you "need" a fuse there. The connections will be protected by a lid on the box. You do need a fuse before the positive cable goes into the system. So, the terminal would be a handy place for the 'catastrophic' fuse. Or where the positive goes through the box, inside or outside. Nice work building the box.
