Tattu R-Line Version 3.0 1550mAh 4s 120C Lipo Battery

4. Product Description

The Tattu R-Line Version 3.0 1550mAh 4S 120C LiPo Battery is designed for FPV racing drones and high-performance RC aircraft that require a compact battery with high current delivery capability. Its four-cell series configuration provides 14.8V nominal voltage and reaches 16.8V when fully charged.

With a capacity of 1550mAh, this battery offers a balance between flight performance, battery size, and weight for compatible FPV builds. The XT60 discharge connector provides the main power connection, while the JST-XHR balance connector allows the charger's balancing system to monitor the individual cells. Its published 120C discharge rating is intended for demanding applications, but actual performance depends on operating conditions and battery health.

Features

• 1550mAh capacity: Designed for compatible FPV and RC applications.

• 4S1P configuration: Four lithium-polymer cells connected in series.

• 14.8V nominal voltage: Suitable for compatible 4S drone power systems.

• 240C listed burst rating: Specified for short-duration peak demand; follow the manufacturer's operating limits.

• XT60 connector: Main power connection for compatible equipment.

• JST-XHR balance connector: Supports cell balancing during charging.

• Compact racing format: Approximately 77 × 38.5 × 32.5mm.

• R-Line V3 series: Designed for demanding FPV racing use.

Applications

• FPV racing drones

• 4S freestyle quadcopters

• Compatible 250-size RC aircraft

• High-performance hobby drones

• RC projects requiring a compatible 14.8V LiPo battery

How to Use

1. Verify that your drone or RC equipment supports a 4S LiPo battery with a nominal voltage of 14.8V.

2. Check XT60 connector compatibility and polarity before connecting the battery.

3. Charge using a dedicated 4S LiPo balance charger with a maximum pack voltage of 16.8V.

4. Connect the balance plug according to the charger's instructions so the individual cells can be monitored and balanced.

5. Secure the battery firmly in the drone frame before flight.

6. Monitor battery condition and voltage during use, and stop operation before excessive discharge.

Important Notes

• Use a compatible 4S LiPo charger only. Do not exceed 16.8V when charging this standard 4S pack.

• Charge on a non-flammable surface and never leave the battery unattended while charging.

• Do not use the battery if it is swollen, punctured, damaged, or unusually hot.

• The 120C and 240C figures are listed discharge ratings, not a guarantee that every setup can safely sustain those currents.

• Check your drone's ESC, motors, wiring, and connector ratings before use.

• Avoid short circuits and incorrect polarity.

• For longer storage, use the storage-voltage setting recommended for LiPo batteries rather than leaving the pack fully charged or deeply discharged.

• Confirm the exact battery dimensions and weight if the drone frame has limited space.
