Here is the Rav4 Battery pack.

So how are YOU planning on implementing fusing?jimbo69ny said:No cell fuses like the Tesla modules though. Fine for a small bike that you can jump off of but in a car with high amperage demands you need cell level fusing in your modules. It would be nice if I could put it together like his though. It would be soooo much easier!

I still maintain that designing the pack connection for constant moderate amperage discharge is a better approach than tying it directly to the main pack and letting the current flow however it needs to.
miimura said:I would be wary of soldering directly on the battery cells. This guy built a 18650 based pack for his scooter. He set up spot welding. If you soldered the wires to a tab and spot welded the tab to the cell, I think that would be a better solution. Even better, figure out how to spot weld or wire bond the wires to the cell like Tesla does.
