Usage & Safety Guidelines

• Use a dedicated lithium-ion smart charger supporting CC/CV charging mode up to 4.20V.
• Never charge above 4.25V per cell or discharge below 2.5V per cell.
• Never exceed the maximum continuous discharge current of 30A.
• Always inspect cell outer shrink wrap, insulator ring, and terminals for damage before use; rewrap immediately if damaged.
• Never carry loose 18650 batteries in pockets, bags, or purses with metal objects like keys or coins; always store in an insulated battery case.
• Do not short-circuit, crush, incinerate, puncture, or submerge cells in water.
• Store batteries at 3.60V–3.85V per cell in a cool, dry, well-ventilated location away from direct sunlight.
• When building multi-cell packs, always integrate a quality Battery Management System (BMS) with over-current, over-charge, over-discharge, and thermal balance protection.
