5 FAQs of WELLGO 2s4p Nickel Sheet Connector 18650 Copper-nickel Busbar 21700 Composition Sheet Copper Nickel Bus Bar

**What does the 2s4p configuration mean in the WELLGO Nickel Sheet Connector?**
The “2s4p” denotes a battery setup with two cells connected in series (2s) and four such series groups connected in parallel (4p). This configuration increases voltage via series connections (e.g., 7.4V for two 3.7V lithium cells) and capacity/current via parallel links. The WELLGO busbar simplifies this wiring, ensuring secure connections for stable power delivery in applications like DIY battery packs or solar storage systems.

**Why is the busbar made of copper-nickel composition?**
Copper offers superior electrical conductivity, minimizing resistance and heat generation, while nickel provides corrosion resistance and durability. The layered design (copper core with nickel plating) balances performance and longevity, ideal for high-current environments. This hybrid material prevents oxidation common in pure copper and avoids the higher cost and lower conductivity of pure nickel, making it efficient and cost-effective.

**Is this busbar compatible with both 18650 and 21700 batteries?**
Yes. The WELLGO Nickel Sheet Connector is designed to work with cylindrical lithium-ion cells, including 18650 (18mm diameter, 65mm height) and 21700 (21mm diameter, 70mm height) sizes. The flexible nickel sheets can be trimmed or adjusted to fit varying cell spacings, ensuring secure spot-welded connections regardless of battery dimensions.

**What advantages does this busbar offer over pure copper or nickel alternatives?**
Compared to pure copper, the nickel coating reduces oxidation and improves solderability without sacrificing conductivity. Against pure nickel, the copper core enhances current-carrying capacity, reducing energy loss. The layered structure also improves mechanical strength, resisting bending or cracking during installation. This makes it ideal for high-drain applications like EVs or power tools, where reliability and efficiency are critical.

**How do I safely install the WELLGO busbar?**
Use spot welding to attach the sheets to battery terminals, ensuring low-resistance bonds without heat damage. Avoid soldering, as excessive heat can harm cells. Double-check polarity (series vs. parallel connections) to prevent short circuits. Secure loose ends with insulation tape or heat shrink tubing. Always test connections with a multimeter before full deployment to verify voltage and continuity.
