An 8P 18650 pack pulls serious current. With eight cells in parallel, you are running 40–80A continuous through a single strip plane in e-bike and power tool applications. At those currents, a nickel-plated steel interconnect develops hot spots within months — the plating micro-cracks at each weld point, the steel substrate oxidizes, contact resistance climbs, and the pack degrades. Pure nickel at 99.6% minimum content does not do this. No plating to fail, no substrate to rust, no creeping resistance to chase with a multimeter six months after assembly. DLX stamps 8P nickel strip at 18.5mm pitch — the tightest standard spacing for 18650 cells — in N4, N6, Ni200, and Ni201 grades across 0.1/0.15/0.2 mm thickness. Every connector in the spool holds the same pitch, the same surface, and the same chemistry as the first.
99.6% Minimum Nickel — No Rust, No Plating Failure, No Resistance Drift
Nickel-plated steel costs less at purchase but costs more over the pack's service life. When plating micro-cracks at each spot weld — and it will — the exposed steel rusts, contact resistance rises, and I²R heating accelerates degradation. Pure nickel at 99.6% Ni is the same material all the way through. There is no substrate to expose, no plating to fail, and no corrosion mechanism that activates under normal battery operating conditions.
18.5mm Pitch — Tightest Standard 18650 Spacing, No Dead Air
At 18.5mm center-to-center, cells sit with approximately 0.5mm clearance — the minimum gap compatible with standard 18650 cell holders. Every millimeter of unnecessary pitch adds pack length. For an 8P * 10S config, switching from 20.2mm to 18.5mm pitch saves over 13mm in pack width — often the difference between fitting a standard enclosure and paying for a custom housing.
8P Configuration — Pre-Formed, No Hand-Cutting Eight Links per Cell Group
Building an 8P pack with individual links means cutting, positioning, and welding 16 separate nickel pieces per series group. DLX ships 8P strip as a single pre-formed component: load the spool, index the strip, and weld all eight cells in one pass. Labor per pack drops from minutes to seconds. Alignment is repeatable because the strip geometry is, too.
0.1 / 0.15 / 0.2 mm Thickness — Match Current Without Oversizing
Three standard gauges, each hydrogen-annealed to consistent hardness. 0.1 mm for packs under 20A continuous. 0.15 mm — the industry workhorse — handles 20–50A with standard 8–12 Ws weld settings. 0.2 mm for 50–80A high-drain applications where cross-sectional area must keep I²R losses below 2% of pack capacity. Using 0.2 mm where 0.15 mm would suffice adds unnecessary weight and welding difficulty — we stock all three so you don't have to compromise.
Nickel-Only Facility — The Purity on the Certificate Is Real
DLX's 12,000 m² plant processes only nickel and nickel alloys. No stainless, no copper, no steel runs on the same production line. When your strip specification says 99.6% Ni minimum, the OES spectrometer reading on your heat confirms 99.6% Ni — not 99.6% minus whatever the previous campaign left behind. That distinction matters when the strip is carrying 80A through a pack you warrantied for three years.

Changzhou DLX Alloy Co., Ltd. does not just claim corrosion resistance — we test it. Every production batch of nickel strip is sampled for 96-hour accelerated salt spray exposure (ASTM B117, 5% NaCl). Pure nickel strip must show zero red rust and zero visible pitting to clear the gate. We run nickel-plated steel control coupons alongside as a reference — so our customers see, quantitatively, what they are choosing between. This testing discipline, combined with our nickel-only 12,000 m² facility and ISO9001-certified quality system (established 2002), means the anti-corrosive property you specify is a verified specification, not a marketing claim. Serving battery pack manufacturers across 40+ countries, DLX ships 500 tons of nickel strip per month — each coil backed by a heat-specific EN 10204 3.1 MTC.
Q: Why does 8P nickel strip cost more than nickel-plated steel — and is it worth it?
Nickel-plated steel costs 40–60% less at purchase. The cost shows up later: in a pack that has been in the field for 12–18 months, the plating micro-cracks that form at every spot weld allow electrolyte vapor and ambient humidity to reach the steel substrate. Rust begins. Contact resistance rises from milliohms to tens of milliohms. I²R heating accelerates. The pack loses capacity and, in a worst case, develops localized hot spots that trip the BMS or worse. Pure nickel at 99.6% Ni has no substrate to expose and no plating to fail. It stays conductive. It stays connected. For packs with a warranty longer than six months, the math favors nickel.
Q: What is the practical difference between 18.5mm and 19mm pitch?
0.5 mm per cell. In an 8P strip, that is 3.5 mm across the full width — small enough that both pitches fit standard 18650 cell holders, large enough that a jig machined for 19mm will not align correctly with 18.5mm strip. Measure your cell holder or welding fixture center-to-center distance. That measurement is the pitch you need. If you are designing a new pack and space is tight, 18.5mm is the most compact standard option.
Q: Can you supply 8P strip in both plain (H-type) and continuous (U-type) patterns?
Yes. H-type (individual cell links connected by a spine) and U-type (continuous serpentine) patterns are both available in 8P configuration. H-type is more common for packs where individual cell fusing is desired — the narrow link between the cell tab and the main bus acts as a sacrificial fuse. U-type provides the lowest possible resistance for high-current packs where fusing is handled by a separate BMS circuit. Specify your preference at inquiry.
Q: How do you verify that your strip won't corrode in my application?
We run ASTM B117 neutral salt spray testing on sample strips from every production batch: 5% NaCl at 35°C for 96 continuous hours. Acceptance criteria: zero red rust, zero visible pitting at 10* magnification. If your application involves a specific electrolyte chemistry or environmental condition beyond standard salt spray, we can arrange application-specific corrosion coupon testing. Provide your test protocol and we will quote the validation run.
Q: What thickness should I use for an 8P pack?
For an 8P pack, the eight parallel current paths share the load, reducing the per-strip current compared to lower-P configurations. 0.15 mm is the standard recommendation for most 8P 18650 builds — it welds reliably at 8–12 Ws and handles the aggregate current of a typical 8P pack. Use 0.2 mm if your continuous discharge exceeds 60A per parallel group or if your pack experiences mechanical shock or vibration (power tools, EV modules). Use 0.1 mm only for low-current applications under 15A per group where weight and welding energy are the primary constraints.
