What Is the SHONAN Pure Nickel Strip?
The SHONAN Pure Nickel Strip is a roll of thin nickel strip used to connect cells in battery pack projects. The source article lists the strip as 99.6% pure nickel with a 0.1 x 5 mm profile and a 32 ft length. That combination gives you a narrow, flexible strip that can be cut to fit custom layouts.
This product is mainly for buyers who already understand battery pack layout and spot welding. It is not a finished battery, battery management system, charger, or insulation kit. You still need the right cells, a correct pack design, a suitable spot welder, proper insulation parts, and safe testing steps.
Who Should Buy It?
Best For
- DIY battery builders working with 18650 lithium-ion cells.
- Users who prefer pure nickel strip over lower-grade connection material.
- Projects that need a cut-to-length 32 ft roll for several small layouts or practice welds.
Skip If
- You need a complete battery kit with cells, BMS, insulation rings, and wiring included.
- Your pack design requires a different strip thickness, width, or current capacity.
- You do not have safe spot-welding tools or experience working around lithium-ion cells.
Material Properties and Battery Connection Quality
The biggest reason to consider this roll is the listed 99.6% pure nickel material. In battery work, the connection strip must carry current and stay stable after welding. Pure nickel is valued because it resists corrosion better than many plated materials and can create clean weld points when paired with the right spot welder.
The 0.1 x 5 mm size also matters. A 5 mm width can fit common 18650 cell tops without taking up much room, and the 0.1 mm thickness gives the strip a flexible feel for small custom layouts. The tradeoff is that thin strip should be matched to the pack design. Do not assume one nickel size works for every load.
Spot Welding Performance
The article-supported use case for this SHONAN roll is spot welding to 18650 cells. That is the right general method for many battery packs because it avoids prolonged heat on the cell compared with direct soldering. You still need to use a welder that can handle thin nickel strip and make consistent welds without burning through the material.
Good weld quality depends on more than the strip. Clean cell terminals, flat contact, steady pressure, and correct welder settings all affect the result. If the weld is weak, the pack may develop resistance, heat, or intermittent power. If the weld is too aggressive, you can damage the strip or the cell surface.
Pro Tip: Cut a short test piece and make practice welds before using the strip on your actual battery pack. A proper test helps you confirm that the strip, cell surface, and spot welder are working together before you risk your main cells.
Fit and Compatibility for 18650 Projects
The listed compatibility focus is 18650 cells, which are common in DIY lithium-ion battery packs, e-bike packs, and some portable electronic tool battery projects. The 5 mm width is narrow enough for many cell layouts, and the 32 ft roll gives you room to cut strips for series and parallel connections.
Compatibility is still design-specific. Your cell count, parallel groups, series layout, maximum current, enclosure space, and BMS wiring can all change the strip size you need. Before buying, sketch the pack layout and confirm that 0.1 x 5 mm strip matches the electrical and physical requirements of your build.
Before You Buy: This 0.1 x 5 mm strip is not a universal battery connector. Confirm your current requirements, cell layout, and spot welder capability before using it in an e-bike, tool pack, or any high-load battery project.
Quality Assurance and Performance
The original article describes quality control and performance testing tied to purity, durability, and energy transfer. The most useful takeaway is that a consistent strip material matters. Uneven material, plating issues, or poor strip hardness can make welds harder to repeat.
For you, the practical test is simple: the strip should cut cleanly, lie flat on the cell, and weld without tearing, sparking heavily, or lifting under a light pull test. A battery pack is only as reliable as its weakest connection, so inspect every weld before wrapping or installing the pack.
How It Performs in Real Use
For DIY 18650 Battery Packs
For small 18650 layouts, the 32 ft roll gives you enough strip to measure, cut, test, and correct mistakes. The thin 0.1 mm profile can be easier to shape than thicker strip, especially when you are working in a tight holder or enclosure.
For E-Bike Battery Planning
The source article mentions e-bike use, but this is where sizing matters most. E-bike packs can pull higher current than small electronics, so you should confirm that 0.1 x 5 mm strip fits your electrical design. If your plan calls for thicker strip, wider strip, or multiple layers, do not treat this roll as a shortcut.
For Portable Electro-Tool Battery Projects
Portable tool packs need stable connections because vibration and current demand can stress weak welds. Pure nickel strip can help with corrosion resistance, but the pack still needs proper cell matching, insulation, and strain relief. Inspect the strip after welding and before final wrapping.
For Practice and Long-Term Storage
A 32 ft roll is useful because you can use short sections for practice welds before the final build. Store the unused strip in a cool, dry place so it stays clean and easier to weld later. Keeping the roll away from moisture also helps protect the surface from corrosion.
How to Use It Correctly
Start by confirming your battery layout before cutting any strip. Measure the distance between cell terminals, leave enough length for a flat contact area, and avoid sharp bends that can lift the strip from the cell. Use clean cutters so the ends are neat and less likely to snag insulation.
When spot welding, keep the strip flat against the cell terminal and avoid overlapping loose pieces that could shift. Do not work near metal scraps, loose jewelry, or exposed conductive tools that could short a cell. After welding, inspect every connection and test the pack according to your battery design before use.
Compatibility and Safety Notes
Battery building carries real risk because lithium-ion cells can short, overheat, vent, or fail if handled incorrectly. SHONAN Pure Nickel Strips are only one part of the system. You also need compatible cells, a safe BMS, correct insulation rings, proper pack wrapping, and a charger that matches the finished pack.
Use eye protection and insulated tools when working around cells. Do not solder directly to 18650 cells unless the cell manufacturer and your pack design allow it. If you are not comfortable designing lithium-ion packs, get help from a qualified battery technician before using any nickel strip in a live pack.

Is It Worth the Price?
The SHONAN Pure Nickel Strip is worth considering if you need a pure nickel roll for small battery pack work and you already have the tools to use it safely. The value comes from the 99.6% nickel material, the 32 ft length, and the practical 0.1 x 5 mm size for many 18650 layouts.
It is a stronger value for buyers who care about material quality and corrosion resistance than for buyers who only want the cheapest strip. It is not the best fit if your project requires a different thickness, a wider strip, or a complete battery-building kit with all safety accessories included.
How It Compares to Alternatives
Compared with nickel-plated steel strip, this SHONAN roll makes more sense if you specifically want pure nickel material for corrosion resistance and battery connections. Nickel-plated steel may cost less, but it is a different material and may not give the same welding or corrosion behavior.
Compared with thicker or wider pure nickel strips, this 0.1 x 5 mm roll is easier to cut and shape for smaller layouts. A thicker strip may be better for higher-current designs, so compare strip size against your pack plan before choosing.
Frequently Asked Questions
Can SHONAN Pure Nickel Strips be used with 18650 cells?
