⚠️ Important Usage Notes

To maximize battery performance and lifespan:

1️⃣ Avoid high temperatures: Do not expose the battery to temperatures above 65°C or direct sunlight. High heat may cause swelling or capacity degradation.
2️⃣ For low-power applications: This cell is not suitable for high-current or motor-driven devices.
3️⃣ Storage condition: Keep at 40–60% charge (around 3.7V) if stored long-term; recharge every 3 months.
4️⃣ Avoid overcharge/over-discharge: Use a BMS or PCM to extend cycle life.
5️⃣ Use CC/CV chargers: Always charge using a constant current / constant voltage charger designed for LiPo batteries.

❓ Frequently Asked Questions (FAQ)

Q1: Is the battery suitable for continuous 24-hour operation?

A: Yes, provided that current draw remains within rated limits and temperature stays under 60°C. Continuous use beyond rated current or thermal limits may cause degradation.

Q2: Can this battery be used in high-drain applications?

A: No. It’s designed for low-power devices; for high-drain or motor-driven products, consider higher-capacity or Li-ion cylindrical cells.

Q3: Does this battery require balancing when charging multiple cells?

A: Yes, if used in multi-cell series configurations, always use a balancing charger or BMS to ensure each cell maintains the same voltage during charge and discharge cycles.

Q4: Does it have built-in protection?

A: Yes, it features an integrated PCM for overcharge, over-discharge, and short-circuit protection.
