Battery Tab Spot Welder


Active Member
I see that Amazon and other sellers now have some very inexpensive spot welders for battery tabs.

Does anyone here have any experience with them and recommendations?

They are probably all very similar, we've had a Sunko one from Banggood for a few years now and it's been really good. I would suggest you use the thinner metal strips though (0.1mm) rather than 0.2mm ones. We replace a lot of batteries, and build up battery packs, it's been a great help.

With all of the rechargeable battery packs that I have, it should pay for itself quite quickly.
