Hi! I'm building a battery and i was thinking to buy one of this spot welder i found on Alibaba (https://www.alibaba.com/product-det...z1ez&priceId=24afe8e2695d4994a222167de5929e71)

The goal is to try and get as equal welds as possible, but I don't know if it may be an overkill. What do you guys think?
Thanks!!!
