Are there sometimes reasons when it's more advisable to fuse individually and times it's not so necessary? Or is it a good idea all the time? Odds of problem without? Why not just the one main fuse? Or what will a the main fuse not protect?
I also wanted to mention what I'm doing so you all can stop me if there are any major problems with it. I doubt there is but before I do too much more, better see if I missed something. I'd decided to do 4x2s10p 12v batteries for my 48v ebike and hook them together for 58v or so. This also gives me the option to use them in a home emergency power bank, boat/camper, and any ebike I like by using. 2 3 or 4 at a time. Even throw one in the car for emergency starts.
I'm in the middle of the first one of the 4 and I keep thinking I'd love to do away with this fusing, because it's such a slow process. I never could understand all the technical reasons why these go together like they do, so copying was the easiest for me, and I should get it all after a build or two. I still don't know where the balance leads go, just hope I can find someone to take my pic of the finished product and mark the leads for me when I'm done.
Here are pics my first attempt at this, and a link to the one I'm trying to copy. On the one at the link, viewers didn't seem to think much of his build but I hope I at least got the basics from it correct...another reason I wanted to run this by you all.

No idea how to get the "not downloaded yet" pictures to download. Any suggestions for another helpful site, I've tried for 30 min to get a pic to post here, something that is normally no problem to figure out, and this post is partially useless without pictures
