What are common pitfalls when integrating 3.7V 1500mAh cells, and how to avoid them?

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...

What are common pitfalls when sourcing 18650 cells, and how can they be avoided?

Common pitfalls when sourcing 18650 cells include:Rewrapped or "Mystery Brand" Cells: Counterfeiters often rewrap low-grade cells as premium models. Fix: Insist on traceability and test samples for weight, IR, and capacity consistency.Grade B Bargains: Off-spec cells may pass basic tests but fail prematurely. Fix: Specify Grade A cells with written grading criteria; derate performance expectations...
