Li-ion Batteries Warning

WARNING: Lithium ion batteries may explode or burn if not used correctly or if damaged. Use these batteries for the purpose they are intended for. Always check the official datasheet from the manufacturer, always use in combination with a protection circuit (e.g. a BMS), failing to do so may cause severe injury and damage.

Use caution while working with lithium batteries, as they can explode or burn if mishandled. As a buyer and user, you are responsible for educating yourself on how to properly handle and work with these batteries. Always use common sense when charging, discharging, assembling, handling, and storing these batteries.

Tips on how to use and maintain lithium batteries

• Never completely discharge batteries (usually below 2.5V for li-ion or 2.0V for LiFePO4, check datasheet)
• Charge fully (usually to 4.2V for lithium ion or 3.6V for LiFePO4) before first use
• Never charge batteries to more than their full charge voltage
• Do not charge unattended
• Do not store your li-ion batteries fully charged for an extended period of time (weeks or more). If you must store your battery for a long time, only store in a case or individual box in a cool and dry place at approximately 3.5-3.7V for li-ion or 3.2V for LiFePO4
• Use only high quality battery chargers
• Do not expose to heat
• Do not connect the positive contact to the negative contact without an appropriate load
• Never exceed the battery's specifications
• Never try to charge or discharge li-ion batteries with battery chargers that are not made for li-ion batteries (e.g. NiMH)
• Always charge these batteries on and within fireproof material
• Never leave rechargeable batteries in a recharging station unattended
• Do not use any rechargeable battery or charger if any visible damage is present, or if known mishandling, accidental or otherwise, has occurred
• Always store and transport rechargeable cells in a safe, non-conductive container (never keep a spare battery loose in a pocket, purse, etc. and always use protective cases) Properly dispose of all battery cells and chargers in accordance with local laws and mandates (if you're unsure, contact your local municipality)
• If a rechargeable battery overheats, hisses, or bulges, immediately quarantine the battery from any combustible materials - ideally, take the battery outside
• If a rechargeable battery catches fire, the FAA recommends pouring water or soda on the battery and surrounding areas - ideally, use a foam extinguisher to quell the fire
