100pcs 2P H type T type Nickel Plated Steel Strips Sheet Soldering Tabs for DIY 18650 Lithium Battery Pack, Battery Connector Tab Battery Cell Spot Welding Welder (T type)

These nickel tabs worked really well. Welded nicely, though I didn’t use the tabs as the 2×2 cells were for part of a larger battery. Still working today with no corrosion. I’d definitely buy again.
