I’ve been looking for a cheap battery tab spot welder for 18650 lithium-ion cells for awhile now.

The usual ones just aren’t worth the cost. For example, for half the cost of a welder, I could buy at least 2 brand new power tool battery packs.

Enter the $16.99 Portable Mini Spot Welder!

At that price, it was worth a shot…

Will it sink or swim? Watch to find out!

• Portable Mini Spot Welder on Banggood.com
• Portable Mini Spot Welder on eBay
• APC UPS 12V Replacement Battery RBC17 on Amazon
• 3.6kW SUNKKO Spot Welder on AliExpress

Oh well… I guess I’ll keep hunting!
