Key pitfalls and mitigations include:
- Misunderstanding Voltage: The ‘3.7V’ label is nominal; actual ranges from 4.2V (charged) to ~3.0V (cutoff). Design electronics to handle this range.
- Ignoring Protection: Always use PCM/BMS to prevent overcharge/discharge. Even low-power devices risk failure without safeguards.
- Assuming Uniformity: ‘1500mAh’ ratings vary by C-rate and temperature. Demand datasheets with test curves and validate independently.
- Cold Charging: Charging below 0°C causes lithium plating. Implement firmware blocks or temperature-sensing chargers.
- Supply Chain Risks: Counterfeit or inconsistent cells harm reliability. Mitigate with AVLs, lot testing, and traceability (QR codes).
Example: Switching to LFP requires redesigning chargers and certifications due to its 3.2V nominal voltage—never assume drop-in compatibility.
