7.4V 1100mAh 2S LiPo Battery (25C High-Discharge Power Pack)

The 7.4V 1100mAh 2S LiPo Battery is a highly popular, lightweight energy solution designed for applications where interior space is strictly limited, but high current delivery is still an absolute necessity. The "2S" configuration means it utilizes two 3.7V lithium-polymer cells wired in series, providing a solid 7.4V nominal output (8.4V when fully charged). Coupled with a 1100mAh capacity, this battery offers a great middle ground—providing plenty of runtime without the added bulk and weight of a full-sized 2200mAh pack.

What defines this specific battery is its 25C continuous discharge rating. This means the battery can safely deliver up to 27.5 Amps of continuous current (1.1A x 25). This high-discharge capability eliminates voltage sag under load, resulting in snappier trigger responses in Airsoft rifles, faster acceleration in small RC cars, and more torque for robotic servos. It comes equipped with a standard 3-pin JST-XH balance lead to ensure safe, equalized charging, and typically features a Mini-Tamiya, Deans (T-Plug), or JST-RCY main power connector.

Key Features & Functional Advantages:

• 25C High-Discharge Rate: Easily sustains heavy current dumps, ensuring your brushed or brushless motors receive all the amperage they need during sudden acceleration or heavy mechanical loads.

• Compact & Lightweight Form Factor: Specifically engineered to fit into cramped battery compartments, making it a favorite for 1/16th and 1/18th scale chassis or the tight buffer tubes of Airsoft rifles.

• Snappy Trigger Response: Outperforms traditional NiMH stick packs by providing instantaneous power delivery, drastically improving the rate of fire and motor spin-up time in automatic electric guns (AEGs).

• Integrated Cell Balancing: Features a dedicated 3-pin JST-XH balance connector, allowing advanced LiPo chargers to monitor and top off both internal cells exactly to 4.2V to prevent premature degradation.

• Consistent Voltage Curve: Maintains a high, flat voltage profile throughout the majority of its discharge cycle, ensuring consistent motor RPMs until the battery is almost completely drained.

Perfect For:

• Airsoft Enthusiasts: The undisputed go-to battery size for upgrading standard AEGs, fitting perfectly into M4 buffer tubes, crane stocks, and PEQ boxes while delivering an excellent rate of fire.

• Micro & Mini RC Vehicles: Provides the perfect power-to-weight ratio for 1/16th and 1/18th scale RC buggies, short-course trucks, and mini rock crawlers.

• Park Flyer Airplanes: An excellent, lightweight power source for 800mm wingspan foam board airplanes and micro 3D helicopters that require a 2S power system.

• DIY STEM Robotics: A superb main power supply for mid-sized tabletop rovers, Arduino-controlled hexapods, and robotic arms operating on a 7.4V logic and motor loop.
