Common Pure Nickel Ratings (Reference)
| Size (mm) | Cross Section | Optimal Current | Max Current |
|---|---|---|---|
| 0.10 x 8 | 0.8 mm² | ~3.2 A | ~5.0 A |
| 0.15 x 8 | 1.2 mm² | ~4.8 A | ~7.0 A |
| 0.15 x 25 (Busbar) | 3.75 mm² | ~15.0 A | ~22.0 A |
| 0.20 x 8 | 1.6 mm² | ~6.4 A | ~9.5 A |
| 0.20 x 10 | 2.0 mm² | ~8.0 A | ~12.0 A |
Disclaimer: This calculator uses standard community-accepted heuristics (approx 4A-5A per mm² for Pure Nickel). Real-world performance depends on strip length, ambient temperature, airflow, and weld quality. Nickel-plated steel has significantly higher resistance and will heat up much faster. Always test your battery packs for heat generation before sealing.
