Capable of up to 120A while staying cool, this highly flexible, 16 x 1.5mm tinned copper braided cable is a great solution for flexible flat battery packs or cables which have to be as flat as possible but carry current through a flexible area (Commonly used in routing electric skateboard decks).
The cable takes solder easily. If you're soldering it to nickle strip, you should do so before spot welding as it sucks up quite a substantial amount of solder and will heat cells significantly.
