Usage & Safety Guidelines

• Use a charger designed for lithium-ion cells and follow the charger instructions. Do not charge above 4.2V per cell.
• Do not discharge below the specified 2.5V cut-off or exceed the 4.87A continuous discharge rating.
• Because this is an unprotected cell, use a suitable external BMS or protection circuit in battery packs.
• Inspect the wrap, insulator ring, and terminals before use. Do not use a damaged cell.
• Keep loose cells away from metal objects and transport them in an insulated case. Do not short-circuit, crush, puncture, or expose cells to water or fire.
• For storage, keep cells in a cool, dry place at an appropriate storage charge.
