Are you soldering? Need lowest possible resistance for high current applications? Our tinned copper flat wire strip busbar comes in different thicknesses and widths.

It is used for soldering solar panels or other electronics, including battery packs. The copper bus wire is more pliable compared to the nickel and can carry more current for the same size. You can effectively substitute our 3mm tinned copper strip for the 8mm nickel strip. If you're putting together a battery pack and do not own a pulse welder, you're better off using the copper strip because it is very easy to solder. You can use some flux and solder it directly to your electronics using minimal, if any solder. Since the strip is already coated in tin, it melts when soldering, completing your joint with no mess.

Common sizes:

3mm wide x 0.2mm thick - very versatile, easy to work with, holds its shape nicely and can carry 3-5 amps with ease. Suggested maximum current 6 A. Perfect for solar and interconnecting small electronics.

6mm wide x 0.2mm thick - most popular for DIY solar panel assembly for paralleling strings. Suggested maximum current, 15 A.

6mm wide x 0.4mm thick - very heavy duty. Perfect for longer runs, interconnecting high discharge battery cells, or main bus line connecting series of solar cells together. Quite rigid and holds its shape. Suggested maximum current, 30 A.

If you order multiple quantities we merge your order and ship one long roll, uncut, so you can procure uncut sections and cut later as you please so there is no waste.
