⚠️ 18650 Battery & Charger Safety Guidelines

Voltage Platform Awareness: 3.2V LiFePO₄ and 3.7V Li-ion cells cannot be mixed or charged with the same settings. Verify charger mode before charging.
Use a Quality Charger: Always use a reliable charger designed for Li-ion or LiFePO₄ chemistry.
Avoid Over-Discharge: Stop discharging when voltage drops below 2.5V–2.8V (Li-ion) or 2.0V–2.5V (LiFePO₄). Recharge promptly.
Avoid Short Circuits and High Temperatures: Do not short the terminals. Keep away from fire, heat, and moisture.
Discontinue if Wrap is Damaged: A torn wrap may cause short circuits. Stop using or rewrap immediately.
Recycle Responsibly: Dispose of used cells at designated recycling facilities.
