You need to make sure you don’t touch your spot welder probes together. I have the same welder, works good but voltage drops pretty quick if your building large packs and doing lots of welds. Also use the file to flatten the probe ends. You shouldn’t have huge sparks , clean your probes if you do. Keep medium pressure but not to much. Resistance needs to be high enough to create a weld.

Awesome tips! I will do that. I'm sure I'll learn some of these tricks of the trade the more I do

You crack me up bro!

I've seen RC battery packs with high discharge rates, such as lithium packs with 10C or 15C, and LiPo packs with more than 30C. Have you considered the C value of your batteries for your homemade battery pack? Additionally, have you noticed any speed differences or overheating issues compared to the original battery pack?

Good question. You can get all sorts of 18650 cells with higher c rating or higher capacity. These ones that came free with the charger definitely don't have the best discharge rate so i can kind of tell but not much. When I build others I'll pick better cells. No overheating so far everything has been going good.

Hey so I don’t understand what the little 3 wire connection was used for ? Why do you need that if you can than just plug it in.

It's a balance lead so that the charger can know the voltage of each cell in the series and charge them evenly

A lot of the problems is not in your power. Your voltage amperage on your little spot welder. It is the amount of pressure you put on the probes too much pressure no good not enough pressure no good got to find that happy middle
