What Is the MatchWhiz 2P Nickel Strip?
The MatchWhiz 2P Nickel Strip is a roll of battery connection strip made for soldering and spot welding tasks. It is shaped for 2P battery layouts, which makes it useful when you need to connect pairs of cells in a repeatable pattern.
The product is aimed at DIY battery pack builders, repair hobbyists, and electronics users who work with 18650 lithium battery packs, Li-Po packs, NiMh packs, NiCd packs, power tools, or connection pieces. Its 5M length gives you room for multiple cuts, test welds, and layout adjustments before your final assembly.
The most useful detail is the combination of 0.15mm thickness, 27.2mm width, and 20.2mm spacing. Those specs help you judge whether it fits your cell holder, cell spacing, and welder capability before you buy.
Who Should Buy It?
Best For
- DIY builders making 2P battery packs with common 18650-style layouts.
- Users who need a 5M roll for several small welding or connection projects.
- Battery hobbyists who want a pre-spaced strip instead of cutting only narrow straight strips.
Skip If
- You need seller-confirmed pure nickel rather than a strip listed as nickel plating strip.
- Your battery layout does not match the 27.2mm width or 20.2mm spacing.
- You do not have the tools or experience to work safely with battery cells.
Before You Buy: Check your required strip material, current load, cell spacing, and welder capability first. This product is listed as a nickel plating strip, so buyers who specifically require pure nickel should confirm the material with the seller before using it in a high-drain pack.
Advantages of the 2P Nickel Strip
The main advantage of this strip is that it gives you a ready 2P pattern instead of making every connection from plain narrow strip. That can save layout time and make repeat battery pack builds easier.
| Advantage | Why It Matters |
|---|---|
| 2P layout | Helps connect paired cells in a repeatable battery pack pattern. |
| 0.15mm thickness | Thin enough for many small battery spot welding jobs when matched with the right welder. |
| 5M roll length | Gives you material for cuts, practice welds, and multiple small projects. |
| Good weldability | Supports secure battery connections when used with correct welding settings. |
| Corrosion resistance | Helps protect connection surfaces in normal storage and use conditions. |
Build Quality and Materials
The listing identifies the material as a nickel plating strip. That wording matters because shoppers often compare nickel-plated strip against pure nickel strip for battery pack projects.
For general DIY connection work, the listed benefits of conductivity, corrosion resistance, weldability, and draw tension are useful. For high-drain packs, e-bike packs, power tool packs, or any pack with strict current requirements, you should size the strip based on the pack design rather than assuming one strip type fits every job.
Fit and Compatibility
The 20.2mm spacing is one of the most buyer-useful specs. If your cells, holders, or brackets line up with that spacing, the strip can make the build cleaner and faster. If your layout uses different spacing, you may need a different strip pattern or a plain strip that you can cut and shape yourself.
The listing calls out use with 18650 lithium battery DIY packs, Li-Po battery packs, NiMh packs, NiCd packs, power tools, and electronic components. That range makes it flexible, but compatibility still depends on your cell size, pack configuration, current requirement, and welding equipment.
Conductivity and Weldability
Good conductivity helps reduce weak connection points in a battery pack, but the strip is only one part of the system. Cell quality, weld strength, connection path, strip thickness, and pack design all affect the final result.
The 0.15mm thickness is a common size for small pack building because many hobby spot welders can handle it better than thicker strip. Still, you should test on scrap pieces first, then inspect whether the weld holds without burning through, tearing the strip, or overheating the cell.
Pro Tip: Cut a few short test pieces from the 5M roll before your final build. Test your welder settings on scrap strip and verify the weld strength before you attach the strip to live battery cells.
Applications in Battery Soldering and Welding
The MatchWhiz 2P Nickel Strip is most useful for battery pack assembly and connection work. You can use it for 18650 lithium battery packs, Li-Po battery projects, NiMh packs, NiCd packs, power tool battery connections, and electronic component connection pieces when the dimensions fit your layout.
Its pre-spaced design helps when you are building a pack with repeated cell groups. Instead of measuring every tab from scratch, you can cut sections from the roll and align them with your cell group.
For lithium-ion cell work, spot welding is usually the safer and cleaner method for attaching strip to cells. Direct soldering on cells can add too much heat if done poorly, so use the correct tool, work carefully, and follow battery safety guidance for your specific cells.
How It Performs in Real Use
For 18650 DIY Battery Packs
The 2P pattern makes the most sense when you are connecting paired cells in a repeated layout. The 27.2mm width and 20.2mm spacing help you judge alignment before you cut the strip.
For Power Tool Battery Projects
The strip can work for power tool battery connection pieces when the pack design supports this size. You should compare the original strip layout, current demand, and cell arrangement before using it as a replacement.
For Practice Welds and Small Repairs
The 5M roll gives you room to practice. That matters because weld quality often improves after you test pulse settings, pressure, and strip placement on spare pieces.
For Long-Term Pack Reliability
A secure weld helps reduce loose connections, heat buildup, and intermittent power problems. The strip can support a clean build, but the final pack still depends on insulation, cell matching, weld strength, and safe assembly.
How to Use It Correctly
Start by planning the cell layout on paper or with a non-powered mockup. Confirm that the strip spacing matches your cell holders before you cut long sections from the roll.
Use clean tools when cutting the strip, and avoid sharp burrs that can damage insulation or battery wraps. After each weld, check for a firm connection without overheating the cell surface.
Do not rely on the strip alone for pack safety. You may also need fish paper, insulating rings, heat-resistant barriers, a proper BMS, correct wire gauge, and a safe enclosure depending on your battery design.
Compatibility and Safety
Battery pack building carries real risk because cells can short, overheat, vent, or fail if handled incorrectly. Always prevent the strip from touching unintended terminals, exposed cell cans, or loose metal tools during assembly.
Use the strip only with a pack design you understand. If you are replacing a strip in an existing pack, match the original layout and electrical requirements rather than choosing a strip based only on size.
If you are unsure about current rating, pack wiring, cell chemistry, or BMS requirements, ask a qualified battery technician before you build or repair a pack. This is especially important for high-drain packs, power tools, mobility devices, and large lithium battery systems.

Is It Worth the Price?
The MatchWhiz 2P Nickel Strip offers strong value for the price if you need a ready 2P strip pattern and a 5M roll for repeated battery work. It is better for buyers who care about layout convenience, practice material, and common 18650 pack compatibility.
Its value depends on your project requirements. If you need a verified pure nickel strip for a high-drain pack, you should compare material details before buying. If you need a practical nickel-plating strip for general DIY welding and battery connection projects, this roll is worth considering.
How It Compares to Alternatives
Compared with plain narrow nickel strip, this 2P version is more convenient for paired cell layouts because the pattern is already shaped for repeated connections. Plain strip may be better if your pack has unusual spacing or you want to design every connection manually.
Compared with small packs of pre-cut tabs, the 5M roll gives you more flexibility for cutting custom lengths. Pre-cut tabs can be easier for simple repairs, but this MatchWhiz roll makes more sense when you need multiple sections for a larger DIY pack or several small projects.
