Hello,
I started building 18650 packs 2 years ago and have been trying my best to make myself reliable packs.
I started with soldering and did that for a while.
i have no problem with soldering the cells, those have always been easy, quick and reliable, I have always had trouble getting the bus bars to solder nicely even if it did stick, I always had trust issues with it, I played around with several different methods such as the amount of flux I used, how hot and how long my soldering iron was on the bars and still didn’t have luck. I even presoldered the wire using a torch.
I had a critical event about 6 months ago and had my batteries fail.
the built in fuse in the cells went out before the soldered fuses did so I decided to swap to spot welding 100% with nickel strips.
I am reusing the bus bars because I don’t want to buy more lugs and wire.
What do you guys think about the design?
There isn’t contact on every strip but I feel there’s enough to make it work just fine.
