Tattu FPV Soft Bag Lithium Battery for Racing Drones 75C 95C 300mAh 450mAh

When building or maintaining an FPV crossing machine, every gram and every discharge cycle matters. The Tattu soft bag lithium battery range is engineered to deliver high current bursts with a 75C or 95C discharge rating, ensuring your racing drone has the instant power needed for quick acceleration and sharp manoeuvres. Available in capacities of 300mAh and 450mAh, and in 1S, 2S, and 3S configurations (3.7V to 14.8V), you can select the pack that matches your frame size and motor requirements. Each battery comes with an XT30 connector already fitted, saving you soldering time. The soft pack design reduces weight and lets the battery flex slightly to fit snugly inside tight drone frames.

Features and Construction

The Tattu soft bag battery is built for the high-stress environment of FPV racing and freestyle flying. Its construction prioritises low internal resistance and consistent voltage delivery under load.

Discharge Rate and Capacity

Choose between 75C and 95C continuous discharge rates. The 300mAh version is ideal for lighter, ultra-short race builds, while the 450mAh packs provide a balance of weight and flight time. The high C-rating supports punchy throttle response without significant voltage sag.

Voltage and Connector

The battery is available in 1S (3.7V), 2S (7.4V), and 3S (11.1V, 14.8V) configurations. All packs are fitted with an XT30 connector, a compact and low-resistance plug suitable for mini quads and racing drones. Ensure your drone's power lead matches before use.

Soft Pack Build

Unlike hard-case batteries, this soft pack LiPo uses a flexible polymer outer sleeve. This reduces overall weight and allows the battery to conform to the shape of your drone's frame, making it easier to secure with straps or foam padding.

Uses and Placement

These batteries are specifically designed for FPV racing drones, freestyle quads, and small crossing machines. Their lightweight nature and high discharge capability make them a common choice in competitive and sport flying.

Racing and Freestyle Drones

For 3-inch and 5-inch racing builds, the 450mAh 3S or 2S options offer a good power-to-weight ratio. The 300mAh 2S pack is well suited to ultra-light micro drones where every gram counts.

Professional and Hobbyist Builds

Whether you are building a new quad or replacing worn batteries in an existing FPV crossing machine, the Tattu packs are drop-in compatible with most XT30 equipped flight controllers and power distribution boards.

Voltage Matching

Always select the voltage that matches your drone's motor and ESC configuration. 1S packs are commonly used in tiny whoop-style aircraft, while 2S and 3S cover the majority of mini racing and freestyle quads.

Benefits and Buying Value

Buying a Tattu soft bag battery means prioritising consistent discharge performance and ease of installation. The XT30 connector is widely adopted in the FPV community, and the soft pack format helps you save weight.

Reuse and Charging Care

LiPo batteries last longest when charged correctly. Use a balance charger set to the correct cell count (1S, 2S, or 3S) and always charge on a fireproof surface. Store at storage voltage (around 3.8V per cell) when not in use for more than a few days.

Why Choose This Product

Tattu is a recognised brand in the FPV world, and these batteries are designed to the specifications that racers need: high C-rating, multiple capacity and voltage options, and a lightweight soft pack format with pre-fitted XT30 connectors. No guessing, no extra soldering – just match the spec to your drone and fly.
