SHONAN Pure Nickel Strips – 0.15x8mm
Features: 99.6% pure nickel, 0.15x8mm, 32 ft length, suitable for spot welding to 18650 cells and other battery components. Nickel offers excellent corrosion resistance and high current capability. The strips are commonly used where reliable conductivity and welding ease are needed, with awareness that nickel can be magnetic near room temperature.
Best for: Builders creating larger or higher-current packs where wide strips reduce resistance and improve welding throughput. This option is chosen for projects needing robust current paths and fewer parallel connections.
Caution: Nickel is magnetic at room temperature; plan for magnetic considerations during handling and assembly. Ensure compatible welding equipment and safety practices for high-current welding.
SHONAN Pure Nickel Strip – 0.15x6mm
Features: 99.6% purity, 0.15x6mm, designed for easy spot welding to lithium-ion cells and other circuits. Nickel strips offer strong corrosion resistance and good conductivity, suitable for mid-width pack configurations.
Best for: Projects where mid-width strips balance current handling with maneuverability. Useful for medium-sized packs with constrained space.
Caution: As with all nickel strips, ensure correct welding parameters to avoid overheating or warping in tight layouts.
SHONAN Pure Nickel Strips – 0.15x5mm
Features: 99.6% purity, 0.15x5mm, 32 ft length, easy welding for compact cell arrays. Nickel strips provide consistent electrical paths with good corrosion resistance.
Best for: Small- to mid-sized packs where space is tight and precise strip width is necessary. Suitable for compact or modular pack designs.
Caution: Narrow strips may require more careful alignment and multiple welds to spread current evenly across cells.
VIPAKE Nickel Plated Strip – 0.15x32mm
Features: Nickel plated steel, 0.15x32mm, 16.4 ft roll, suitable for 21700 or larger packs. Provides extended current path with length optimization for series connections.
Best for: Projects needing long, continuous current routes and easier layout planning for larger-format packs. Better for linear configurations and reduce the number of welds.
Caution: Nickel plating properties can influence solderability; ensure compatibility with your welding or soldering process for best results.
Buying Guide: 0.15 Inch Nickel Strips For Battery Packs
What thickness and width should I choose?
Thickness affects current capacity and mechanical rigidity. Wider strips (like 0.15x8mm) handle higher current with fewer parallel paths, while narrower options (0.15x5mm) fit tight spaces but may require more welds. Consider the pack size, cell type, and welding method when selecting width.
Pure nickel vs nickel-plated strips
Pure nickel strips offer excellent conductivity and corrosion resistance, ideal for high-current builds. Nickel-plated options can be more cost-effective and provide adequate performance for many standard packs. Choose based on your current requirements and welding compatibility.
Welding considerations
Spot welding nickel strips requires appropriate equipment and technique. Higher purity strips may weld differently than plated ones. Ensure your welder is set for nickel, and practice on scrap material to minimize cell damage.
Length and layout considerations
Long strips reduce the number of welds but may bend or warp in tight spaces. Plan your pack layout to minimize bending and ensure clean, direct current paths from one bus to the next. Secure strips to prevent movement during assembly.
Safety and handling
Work in a well-ventilated area and use eye protection. Nickel dust and metal shards can pose hazards. Follow standard safety protocols for battery assembly and welding operations.
Which product is best for you?
- Best for high-current, large packs: 0.15x8mm strips (SHONAN 0.15x8mm).
- Better for balanced current and easier handling: 0.15x6mm strips (SHONAN 0.15x6mm).
- Choose this for tight spaces in compact packs: 0.15x5mm strips (SHONAN 0.15x5mm).
- Best for long, linear current paths in bigger packs: 0.15x32mm strips (VIPAKE).
- Consider a non-nickel option if cost savings are critical and current needs are moderate.
FAQ

They offer a good balance of current capacity, mechanical flexibility, and welding ease for many battery configurations.
Yes for high-current and long-term corrosion resistance; nickel-plated strips can be more economical with adequate performance for many builds.
Yes, 18650-compatible nickel strips are common, but verify welding parameters and strip dimensions for your specific cells.
Wear eye protection, work in a ventilated area, and follow battery handling safety. Practice on scrap pieces before building a live pack.
No. 32mm is best for longer series connections and larger packs; smaller packs benefit from narrower strips to fit in confined spaces.
