Battery Tattu R-Line 550mAh 7.4V 95C 2S1P XT30

The Tattu R-Line 550mAh 7.4V 95C 2S1P XT30 is a compact lithium polymer battery designed for high-performance remote applications. With a nominal voltage of 7.4V and a usable capacity of 550mAh, this battery provides a reliable power source for small racing drones, micro quadcopters and first-person view (FPV) setups. The 95C continuous discharge rating supports rapid current draw while the 2S1P cell configuration and XT30 connector ensure consistent power delivery and a secure electrical connection.

Advantages

The battery combines a high discharge rate with a lightweight form factor to deliver strong acceleration and stable power under load. Its 2S1P layout reduces complexity and weight compared with larger multi-cell packs, while the XT30 connector offers low-resistance contacts and easy installation. The 95C rating helps reduce voltage sag during intense maneuvers, and the compact 550mAh capacity balances flight time and agility for small, performance-focused aircraft.

Suitable for

• Micro and mini FPV racing drones
• Lightweight freestyle quadcopters
• Indoor and outdoor short-duration flights
• High-discharge applications requiring stable bursts of current

• Continuous discharge rating: 95C
• Cell configuration: 2S1P (two series cells, single parallel)
• Connector type: XT30
• Chemistry: Lithium Polymer (LiPo)
• Intended use: high-discharge, lightweight applications

How to use

Before first use, fully charge the battery with a compatible LiPo charger and select the correct charge profile for a 2-cell pack. Connect the XT30 plug to the aircraft power lead ensuring correct polarity. Monitor voltage during operation and avoid discharging cells below the recommended safe voltage per cell; land and disconnect when the battery reaches the manufacturer’s suggested cutoff voltage to avoid damage. After each flight, allow the pack to cool to ambient temperature before recharging and store it at a partial charge if not used for extended periods.

Recommendations

Use a charger with balance capability for 2-cell LiPo packs, inspect the pack before each flight for any swelling, damage or loose connections, and follow safe handling and transport practices for lithium batteries. Match the battery capacity and discharge rating to your aircraft’s motors and ESCs to ensure compatible performance and avoid overstressing components.
