Ahh. Super caps for the welder.
There's a couple DIy battery spot welders on youtube... one repurposes a transformer from a microwave.
With a welder buying all new higher end 18650 cells and reusing the BMS, could yield a far better battery,.at a fraction of the cost.
This cell x 5 for 18v nominal. 2.8 Ah, 35 amp.
20$ + shipping.
