At Unmanned Tech, we wanted to stock proper nickel, not nickel-plated steel with an optimistic product title. So we went looking for a supplier we could trust to supply actual pure nickel strip.\u003c\/p\u003e\n\u003cp\u003eThis is the result: \u003cstrong\u003e0.15mm thick, 7mm wide pure nickel strip, sold by the metre\u003c\/strong\u003e, for cut-to-length connections in custom 18650 and 21700 battery packs.\u003c\/p\u003e\n\u003ch3\u003eWhy Pure Nickel Rather Than Nickel-Plated Steel?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLower resistance:\u003c\/strong\u003e For the same length, width and thickness, pure nickel generally has lower electrical resistance than the steel used in typical nickel-plated strips. At the same current, that means less voltage drop and less energy wasted as heat in the strip.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo steel core to expose:\u003c\/strong\u003e Nickel-plated steel relies on its coating to protect the steel underneath. Cuts or damaged plating can expose that steel to rust; pure nickel remains nickel through the strip and offers good corrosion resistance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA known starting material:\u003c\/strong\u003e You can plan your interconnects around supplier-specified pure nickel rather than guessing what is under a shiny coating. That does not replace checking your pack design or weld quality.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNickel-plated steel has legitimate uses when a pack is designed for it. The problem is treating it as interchangeable with pure nickel, particularly when your current and heat calculations assume the lower-resistance material.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Supplier-specified pure nickel, not nickel-plated steel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 0.15mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 7mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold unit:\u003c\/strong\u003e 1 metre of strip, not a complete stock coil.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Cut-to-length series and parallel cell connections for custom battery packs, including 18650 and 21700 builds.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBefore You Build\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePure nickel is not a current-rating shortcut.\u003c\/strong\u003e A 21700 cell does not automatically make this strip suitable for its full discharge current. Size the interconnects for the actual current path, strip length, temperature rise and weld arrangement. High-current builds may need a different conductor size or an engineered busbar arrangement.\u003c\/p\u003e\n\u003cp\u003eUse suitable spot-welding equipment and settings, check the welds, and provide the correct cell insulation and pack protection. Battery pack assembly requires the skills to avoid shorts and cell damage; better strip material does not make an unsafe pack safe.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eCan I check whether it is pure nickel with a magnet?\u003c\/h4\u003e\n\u003cp\u003eNot reliably. Pure nickel is magnetic too, so attraction to a magnet does not distinguish it from nickel-plated steel. A magnet is not a purity certificate.  As a rule of thumb, if you use a Dremel tool to cut, steel plated strips will spark, pure nickel will not.  And longer term when you scrap\/cut it steel plates will rust, but nickel will not.\u003c\/p\u003e\n\u003ch4\u003eDoes this include the cells or a complete pack?\u003c\/h4\u003e\n\u003cp\u003eI cant believe I have to say this, but no. You receive 1m of 0.15 x 7mm nickel strip for your own pack construction. Cells and other pack components are not included.\u003c\/p\u003e","brand":"Unmanned Tech","offers":[{"title":"Default Title","offer_id":59098229571965,"sku":"PNS0157","price":1.39,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0914\/9972\/5181\/files\/61_TZOqOnBL._AC_SL1500.avif?v=1794519496","url":"https:\/\/www.unmannedtechshop.co.uk\/de\/products\/pure-nickel-strip-0-15-x-7mm-1m","provider":"Unmanned Tech","version":"1.0","type":"link"}
