Standard 19.5mm pitch nickel strip connects adjacent cells. That works for simple parallel groups. It does not work when your pack design staggers cells in alternating rows, or when a series connection must bridge across a parallel group to reach the next cell in sequence. For those layouts, you need a strip that spans two cell positions — 34.5mm center-to-center — not one. DLX stamps this 2P wide-pitch strip to exactly that geometry on a dedicated progressive die, with the same 99.6% Ni200 chemistry, hydrogen-annealed surface, and burr-free edge as our standard-pitch products. If your BOM calls for a 34.5mm interconnect and your current supplier can only offer 19mm or 20.2mm, this is the part that eliminates the hand-soldered jumper wire you have been using as a workaround.
| Grade | Ni Content | Best Use Context | Reference Price (FOB, USD/kg) |
|---|---|---|---|
| Ni200 | ≥ 99.6% | Standard — consumer packs, power tools, e-mobility requiring a 34.5mm series bridge | 54 – 60 |
| N4 | ≥ 99.9% (Ni+Co) | Premium — outdoor/marine packs where the bridge is exposed to humidity | 62 – 70 |
| Ni201 | ≥ 99.0% (C ≤ 0.02%) | High-temp — fast-charge packs where the bridge carries high current and thermal cycles | 50 – 57 |
| N6 | ≥ 99.5% (Ni+Co) | Cost-sensitive — indoor stationary storage with protected bridge routing | 38 – 45 |
Prices FOB Shanghai, 5–500 kg orders. MOQ: 5 kg. Free sample (0.5 kg Ni200) for dimensional fit-check. 34.5mm pitch is a maintained die — confirm stock availability at inquiry; if a new run is required, lead time is 7–10 working days.

Quality Assurance — Wide-Pitch Inspection ProtocolPackaging & DeliveryDelivery: 34.5mm pitch is a maintained die — confirm stock with inquiry. If in stock: 3–7 working days. If a new stamping run is required: 7–10 working days. Air freight < 30 kg; sea freight for bulk. Departure: Shanghai.
Changzhou DLX Alloy Co., Ltd. did not arrive at 34.5mm pitch by accident. It entered our die library because a battery pack manufacturer needed a strip that could bridge from cell position 1 to cell position 3 in a staggered 2P array — and the standard 19.5mm strip could not do it. That is how most of our 2,000+ battery-specific dies originated: a customer with a real assembly problem, and a DLX toolroom with the Sodick EDM capability to cut the solution. Since 2002, our 12,000 m² nickel-only facility in Changzhou has operated on the principle that specialized tooling is not overhead — it is the reason customers return. Whether your pitch is 18.5mm, 19.0mm, 19.5mm, 20.2mm, 20.5mm, or 34.5mm, DLX has the die, the nickel chemistry, and the inspection discipline to deliver exactly what your drawing specifies. ISO9001 certified, 500 tons monthly capacity.
34.5mm is approximately double the standard 18.5–19.5mm single-cell pitch. It is used when a nickel connector must span across one cell position to reach the next — typically in staggered-row 2P pack layouts, series connections between physically separated parallel groups, or designs where a thermal barrier or structural rib sits between the two cells being connected. Instead of hand-soldering a jumper wire across the gap, the pre-formed 34.5mm strip provides a rigid, repeatable bridge with consistent weld quality at both ends.
34.5mm corresponds to two standard 18650 cell diameters (2 * 18.25mm nominal, adjusted for the slight gap between cells in a holder). This pitch lands the weld tabs directly on the center of cell 1 and cell 3 in a linear array, perfectly clearing cell 2. If your layout requires a different double-span distance — say 37mm for 21700 cells — we can cut a custom die. Provide your center-to-center measurement and we confirm feasibility within 24 hours.
The 34.5mm die is maintained in our tool library, but production runs are scheduled based on demand — this is not a continuous-run item like 19.5mm pitch. If strip from a recent run is in inventory, we can ship within 3–7 working days. If a new stamping run is required, lead time is 7–10 working days. We recommend confirming stock availability at inquiry.
The bridge itself adds a short length of nickel conductor — approximately 15mm longer than a standard single-pitch connector. At 0.096 μΩ·m resistivity and a typical 0.15mm * 5mm bridge cross-section, this adds roughly 1.9 milliohms of series resistance — negligible in the context of a battery pack where individual cell internal resistance is 20–50 milliohms. The weld quality at the tabs is identical to standard-pitch strip because the tab geometry, material, and surface are unchanged.
Yes. The same die stamps N4, N6, Ni200, and Ni201 strip — only the input coil changes. If your series bridges are exposed to marine humidity or salt-laden air (common in outdoor packs where the bridge runs along the pack exterior), N4 at 99.9% Ni with Fe ≤ 0.04% provides the highest corrosion margin. Specify the grade at inquiry; lead time is unchanged.
