⚠️ 26650 Battery & Charger Safety Guidelines
- Voltage Platform Awareness: 3.2V LiFePO₄ and 3.7V NMC cells cannot be mixed or charged with the same settings. Ensure the charger is set to the correct mode before charging.
- Dimensional Compatibility: 26650 cells are larger in diameter and length than 18650/21700. Verify your device's battery compartment supports 26mm diameter × 65mm length.
- 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 (NMC) or 2.0V–2.5V (LiFePO₄). Recharge promptly.
- Avoid Short Circuits and High Temperatures: Do not short the terminals. Keep away from fire, heat sources, and humid environments.
