Top 3 Customer Questions & Concerns ‍

1. Can I charge this with a standard 18650 charger?

   • Since this battery has a wire and connector, it may not fit in standard "cradle" chargers. It is best charged through the device it is installed in or via a dedicated Li-ion charging module (like a TP4056).

2. What if the connector doesn't match my device?

   • The 7.5cm wire allows for easy modification. If the red connector doesn't match, you can carefully cut and splice the wires to your existing connector (ensure correct polarity: Red is Positive, Black is Negative).

3. Is this battery "Protected"?

   • This cell is a high-quality standard Li-ion cell. For maximum safety, ensure your device has a built-in Battery Management System (BMS) to prevent overcharging or deep discharging.
