Engineering Disclaimer
Please read this technical disclaimer carefully before utilizing any calculations or sizing layouts provided by this website.
IMPORTANT NO CERTIFIED DESIGNS
All calculations, formulas, output estimations, and suggested configurations displayed on Battery Calculators are for preliminary educational and sizing estimation purposes only. They do not constitute certified engineering plans, safety documentation, or compliance designs.
1. Verification Requirement
Battery storage design, high-current DC wiring, and grid arbitrage calculations involve significant physical hazards, including fire, electrocution, thermal runaway, and financial liability.
You must verify all calculations with certified electrical, marine, or civil engineering professionals and reference official standards (such as NEC, NFPA 855, IEEE 1547, ISO 13297, or local building codes) before fabricating any packs or routing wires.
2. Accuracy and Assumptions
Calculators are based on idealized models (e.g. constant wire resistivity, linear temperature derating, simple calendar ageing). Real-world performance varies due to:
- Wire contact resistance and terminal oxidation.
- Transient currents, surges, and inrush loads.
- Inverter dynamic efficiency curves and stand-by power draw.
- Non-uniform thermal gradients inside cell enclosures.
- Local utility tariff changes and demand peaks.
3. Limitation of Liability
Battery Calculators and its developers accept no liability for damage, injury, system failures, fires, or financial losses caused by using these tools. Use of the tools is entirely at your own risk.
