The iFlight FULLSEND 3000mAh 4S1P Li-Ion Battery is designed for micro and mini long-range FPV platforms such as the iH3, AOS 3.5 and similar. Compact, lightweight, and efficient, this pack allows for extended flights on small quads without compromising reliability.

Built with Samsung INR18650-30Q cells, it delivers a balance of energy density and current output suitable for smaller endurance builds.
⚠️ Note: This battery is not designed for high-throttle freestyle or racing — for those applications, a high-discharge LiPo pack is recommended.

Charging Guidelines

Always use a Li-Ion compatible balance charger — never attempt to charge with a non-compatible charger.
Charge at 1C or lower (≤3A for this 3000mAh pack) for optimal safety and cycle life.
Do not exceed 2C charge rate under any circumstance.
Never charge unattended or near flammable materials.
Do not charge below 0°C or above 50°C. Charging outside of this range may cause lithium plating, overheating, or permanent cell damage.
Stop charging immediately if the battery becomes hot, swollen, or shows abnormal behavior.

Storage Guidelines

Storage Voltage: Keep at 3.7–3.85V per cell (≈40–60% charge). Do not store fully charged or fully discharged.
Avoid Drain: Never leave connected to a charger, quad, or device that could slowly discharge it.
Temperature Control: Store in a cool, dry place between 15°C and 25°C. Avoid high heat, direct sunlight, and freezing conditions.
Fire Safety: Always store batteries in a fireproof bag, battery storage bag, or fireproof container. We offer a range of approved LiPo-safe storage solutions in our shop.
Inspection: Check periodically during long storage. If swelling, leakage, or abnormal odor is detected, stop using immediately and dispose of safely.

Disclaimer and Safety Guidelines

Safety Reminder: Always supervise the charging process and keep the battery away from flammable materials. Improper charging, over-charging, or over-discharging can cause overheating, fire, or explosion. Short-circuiting, puncturing, disassembling, or exposing the battery to heat sources or fire may also result in serious injury or damage. Only use compatible chargers designed for Li-Ion batteries. Regularly inspect the battery for damage, swelling, or irregular behavior, and discontinue use immediately if any abnormalities are observed.
