⚠️ IMPORTANT BATTERY NOTICE

• This battery is shipped at Storage Voltage (approximately 3.6V per cell / 14.4V for a 4S pack) to ensure safe transportation and help maximize battery life.
• Do not use the battery immediately after receiving it. Before first use, fully charge the battery using a compatible 4S Li-ion charger.
• Using the battery without fully charging it may cause over-discharge, which can permanently damage the battery cells and reduce battery performance and lifespan.
• If you do not plan to use the battery for more than 5–7 days, store it at Storage Voltage (approximately 3.6V per cell / 14.4V for a 4S pack) in a cool, dry place.
• Do not store the battery in a fully charged (16.8V) or fully discharged (below 10.0V) state for extended periods, as this may reduce its lifespan.
• Always inspect the battery before use. Do not use the battery if it is swollen, damaged, punctured, or excessively hot.
