Here is a Sunkko 788H that I brought back in July, made around 2 packs on it and gave up, I like the piece of mind know my battery was not made by an idiot (me)
Mistakes made on my battery
using fake nickel strips.
using thin nickel strips.
not using fish paper.
not using glue.
not having the spot welder settings high enough.
Anyways spot welder is 90$ shipped, comes with original box and foot pedal.
