One question I often see asked here is whether or not you should fuse both sides of your pack. I always fuse both sides of mine. Not only is the fuse wire very cheap at only $0.055 per foot, you have to solder both sides anyway, so why not? I've seen people say they get copper wire for free so it's cheaper for them to use that instead of fuse wire. Why not use free copper instead, right??
While I was drilling holes to mount my Batrium longmon tonight, I accidentally put too much pressure on the drill and it made contact with the positive busbar on the other side while bumped up against the negative cell casing. Guess what? There was a small spark and the negative-side fuse instantly blew. That's it. If I had used regular copper wire on the negative side, something tells me I'd be pulling and re-soldering 300 more fuses, not to mention some pretty bad burn marks and a drill bit potentially welded to the cell/busbar.
Yes, I should have been more careful. Yes, I should have probably drilled first before installing cells. Human error happens. Next time you're debating fusing both sides, keep safety in mind
