⚠ Important Safety Warnings

Improper use of lithium-ion batteries can cause fire, explosion, or serious injury. These cells are intended only for use in battery packs with a BMS (Battery Management System) or Protection Circuit Board (PCB). Do not use as standalone cells or in e-cigarettes, vape devices, or unprotected applications.

Key Safety Guidelines:

• Never carry loose batteries in your pocket, purse, or bag — risk of short circuit and fire.

• Always store and transport in a protective case.

• Inspect before use: Do not use if damaged, leaking, bulging, or the wrapper is torn.

• Charge safely: Use a smart charger designed for lithium-ion cells. Never overcharge or leave unattended.

• Do not crush, puncture, modify, expose to liquid, solder directly, or short circuit.

• For thermal runaway (swelling, smoke, heat): move to a fire-safe surface and use Class D extinguisher or sand — never water.
