LiPo Battery Extralink 550mAh 3S XT30 100C — for FPV drones and RC vehicles

Extralink LiPo Battery 550mAh 3S with XT30 connector and 100C continuous discharge rating is designed for FPV drones and small RC vehicles that require high-power bursts in a compact form. The battery delivers a nominal voltage of 11.1V (3S) and a 550mAh capacity in a lightweight pack suitable for racing quadcopters, micro drones, and miniature RC models. Inclusion of the XT30 plug ensures secure, low-resistance connection to flight controllers, ESCs, and power distribution systems that accept this common connector type.

Advantages

The 100C discharge capability provides strong instantaneous current for rapid throttle response and aggressive maneuvers while keeping the pack physically small and light. The XT30 connector offers reliable mating and reduced voltage drop compared with some larger plugs, helping maintain power delivery during peak loads. The 3S voltage configuration balances power and weight for many FPV frames and small RC vehicles, offering compatibility with common electronics and ESC settings.

Suitable for

• FPV racing drones and freestyle micro quads
• Small brushless RC cars and trucks
• Indoor and outdoor micro helicopters and airplanes
• Power testing and bench setups for 3S systems

Key specifications

• Capacity: 550 mAh
• Cell count / nominal voltage: 3S / 11.1 V
• Discharge rate: 100C (continuous)
• Connector type: XT30
• Typical application: FPV drones and small RC vehicles requiring high discharge

How to use

Charge the battery with a compatible LiPo balance charger configured for 3S (11.1 V) chemistry and the correct charge current for a 550 mAh pack (commonly 1C to 2C unless otherwise specified). Connect the XT30 plug to the vehicle’s power input, ensuring correct polarity and secure seating. Observe temperature during discharge and avoid excessive deep discharges; follow standard LiPo handling procedures including storage at recommended charge levels when not in use and using a balance lead for charging to maintain cell voltage balance.

Usage recommendations

Use a LiPo-specific balance charger, keep the battery within manufacturer-recommended voltage range, avoid overcurrent conditions beyond the 100C rating, and inspect the pack and connector regularly for damage. Store the battery at approximately 3.8–3.9 V per cell for longer shelf life and follow local regulations for disposal of damaged or end-of-life lithium polymer batteries.
