Replace Motorcycle Battery with LiFePO4

Knowing I had a 1pm appointment with the DMV, which had to be scheduled 2 months prior, I fumbled around in the garage last night until I finally managed to solder 10 gauge wire onto nickel strips. Then I spot welded those strips to the LiFePO4 battery + and -

Well, I've found 1 unsuccessful way to make the main battery leads, and here I am on the forum instead of the DMV. The appointment is rescheduled... 2 months out. I might as well not bother with registering vehicles as long as Oregon isn't serious about it.

The bike almost started a couple of times, but then lost power entirely once the positive lead burned off. I popped the seat off and found a tiny bit of smoke rising from where the positive lead used to be.

Strange that it failed considering I had tested several times with the original nickel leads. Perhaps the strips I used were slightly thinner gauge?

What's the best way for me to get leads with ring terminals on this battery? Ideally I'd just solder the 10 gauge wire directly to the cells, but I'm afraid that would be too much heat for the cell, and I'm not even sure my iron could get hot enough.

Anyhow, this thread is split from this one so that I can focus on the topic of replacing motorcycle batteries with lithium iron phosphate (LFP);
