IMPORTANT NOTE: Understanding how to handle and care for Lithium-ion batteries is very important and should always be practiced. Lithium type batteries are very sensitive to charging characteristics and may explode or flame if mishandled. DO NOT charge your batteries overnight or while unattended for a prolonged period of time! Always charge your batteries in a fire-proof surface/area and DO NOT expose them to high temperatures (e.g. inside your car). DO NOT expose the battery's terminals to metal objects or immerse in water/liquid. We are not responsible for any damage if there is any misuse, abuse or modification of the batteries and/or chargers in any shape or form (including operating while wired in series).
