pure nickel
Product Description
This nickel strip is made of pure nickel and optimized for soldering and connecting battery cells. The 10m roll allows for multiple connections or assembly of several battery packs without changing material. The 0.15mm thickness ensures reliable contact and ease of soldering or pressing.
Parameters and Compatibility
Variants for 21700: two modifications A and B with dimensions 0.15×32.5x23x9.5 mm and 0.15x31x21.5×9.5 mm, respectively. For 18650, there are three variants: A (0.15x27x20.2×7), B (0.15×25.5×18.5×7), and C (0.15x27x20.2×7). Each type is designed for reliable connection of a specific battery format and is suitable for assembling battery packs, replacing contacts, and repairing battery assemblies in drones, power tools, and other portable devices.
Advantages and Usage Recommendations
- Material: pure nickel — high corrosion resistance and stable electrical contact.
- Thickness 0.15 mm — optimal for precise contact and ease of soldering/pressing.
- 10m roll — economical option for serial work or multiple repairs.
- Multiple sizes — ability to select the strip for a specific cell diameter and height (21700 or 18650).
Recommendations: before installation, check the compatibility of the strip dimensions with the shape of your battery compartment; for best contact, use solder or spot welding. For serial production, we recommend using specialized equipment for welding nickel strips and avoiding prolonged heating, which can damage lithium-ion cells. Observe safety precautions when working with batteries.
Application: suitable for battery repair technicians, assembling battery packs in model making and portable electronics manufacturing, as well as for servicing drones and quadcopters.
