Common pack design mistakes, how to avoid?

Many years ago in a undergrad tutorial we worked out the "correct" way to parallel things like battery''s and stuff. and attached was the correct way. If you have a lot of things (resistors or battery''s) in parallel then feed in from one side and out from the other. That way all of the battery''s have equal length leads.

What do you think of my design for a battery pack?

When it comes to battery pack, the most important connection is your series, not parallel. You can use a thin and narrow strip of 0.1mm nickel and it will be enough, given that the parallel connection only carries a tiny amount of current to keep all the cells the same voltage.

6 Frequently Asked Questions about “What is the best way to cut the nickel sheet of the battery pack ”

How thick is a nickel strip on a battery pack?

The nickel strip on the battery packs I have is approx 0.3mm thick and is nickel-coated steel strip. It is welded 4 times per cell per side (2 weld operations, 4 indents from the spot welding pins). The diameter of the indents is approximately 1mm or perhaps 0.8mm. My current approach: The pliers look like these:

How do you cut a nickel strip from a cell?

They use a large box-cutter type knife and a hammer to cut the existing nickel or nickel-steel strip from the individual cells. This is the kind of knife with snap-off blade segments. You want to use the large style, not the small ones. Place the group of cells flat (horizontally) on your work table.

How do you remove old Nickel strips?

When you remove old nickel strip - be carefull not to bend out battery negative side. I always use this to clean old nickel. It's not really easy to remove the nickel depending on how good the welds are. I uses a needlenose pliers to peel up the strips in sort of a rolling action.

How do you remove nickel from a cell?

It's easy to short the pack doing this kind of work, so use tape or cardboard to insulate parts you aren't working on. Once you peel the nickel off, you're left with little chunks of nickel stuck to the end of the cell. The grinding tool like krlenjuska shows is hard to beat but be careful not to take off too much.
