LiPo safety basics: general guidance, not a product promise
Pouch cells store a lot of energy in a thin package, and they deserve respect. This guide covers general handling; it makes no safety certification promise for any specific product.

The first rule is inspection. A cell that is swollen, punctured, bent sharply, or damaged in a crash should be taken out of service and handled according to local hazardous-waste rules, not charged or used further. Swelling is a sign that the cell's internal condition has changed, and continuing to use a swollen cell risks further damage. If a device has been dropped hard or crushed, inspect the battery before the next charge, even if the device still powers on.
The second rule is charging discipline. Charge on a non-flammable surface, use a charger matched to the cell or pack configuration, and do not leave charging unattended for long periods where that can be avoided. Never charge a damaged cell, and never charge a LiPo cell with a charger designed for a different chemistry or a different series count. Heat during charging beyond mild warmth is a reason to stop and investigate, not a normal condition to ignore.
The third rule is storage and disposal. Store cells partly charged in a cool, dry place away from metal objects that could short the terminals — the storage guide gives the general practice. For disposal, use local battery recycling or hazardous-waste routes; do not put lithium batteries in general waste or incinerate them. Certification statements for a specific model are available upon request for that model, and this general guide does not substitute for them.
