LiPo batteries are designed to deliver high performance when used correctly. Always charge using a LiPo-compatible balance charger on a non-flammable surface. A fire-retardant charging bag is highly recommended during charging and storage. Never leave batteries unattended while charging and discontinue use if the battery becomes hot, swollen, or shows signs of damage. Do not over-discharge, short-circuit, crush, puncture, or expose the battery to water or excessive heat. Remove the battery from the replica when not in use and store in a cool, dry place at partial charge. When used by under-18s, adult supervision is required.
