Maybe a dumb question: when welding nickel strip on the negative side of a cell, do you need to go two gears higher than on the positive side? I see the pros setting it that way in videos, but nobody says why.
12V portable power station pack, my first build, lit up on the first try
18650 in 3S8P, U3 Pro at gear 55, 0.15 nickel-plated strip. I'd watched a dozen-plus tutorials and still didn't dare start. Once I actually did it, it wasn't that scary, and the welds are stronger than I expected.
The moment the light came on at the campsite — totally worth it. Thanks to everyone in the comments who taught me.
