The 7.4V 450mAh 2S LiPo Battery is the perfect energy source for applications where every single gram counts, but 1S (3.7V) batteries simply cannot provide enough thrust or torque. This "2S" configuration combines two high-discharge lithium-polymer cells in series, delivering a punchy 7.4V nominal output in a footprint roughly the size of a standard matchbox. It is the absolute standard upgrade for indoor micro-drones, sub-micro helicopters, and 1/24th scale desktop rock crawlers.

Despite its tiny size, this battery is built to perform under pressure. It typically features a solid continuous discharge rating (usually between 20C and 30C), allowing it to easily deliver the burst amperage required for rapid throttle punch-outs or climbing over steep obstacles. To ensure safe and equalized charging, the pack is equipped with a standard 3-pin JST-XH balance lead. For the main power delivery, it most commonly features a lightweight red JST-RCY connector, a micro JST-PH, or an XT30 plug to match popular micro-electronics.

Key Features & Functional Advantages:

  • Ultra-Lightweight Footprint: Weighing in at roughly 25 to 30 grams, it provides the 7.4V power necessary for micro brushless motors without destroying the delicate thrust-to-weight ratio of indoor aircraft.

  • Punchy Discharge Rate: Engineered to sustain steady burst currents without severe voltage sag, ensuring snappy throttle response and consistent motor torque.

  • Integrated Cell Balancing: Features a standard 3-pin JST-XH balance connector, allowing your smart charger to perfectly equalize both internal cells to 4.2V for maximum lifespan and safety.

  • Consistent Power Delivery: Maintains a relatively flat discharge curve, ensuring your micro drones and vehicles handle predictably from the start of the battery to the very end.

  • Low-Profile Dimensions: Specifically sized to slide into the narrow battery trays of popular 1/24th scale chassis and the underbellies of micro quadcopters.

Perfect For:

  • Micro FPV Drones & "Whoops": The go-to power source for 2S brushless micro-drones designed for indoor racing and tight-quarters freestyle flying.

  • 1/24th Scale RC Crawlers: A massive performance and runtime upgrade for micro desktop crawlers like the Axial SCX24, providing incredible low-end torque for steep climbs.

  • Sub-Micro RC Airplanes: Provides the necessary RPMs to fly small, 400mm-wingspan foam park flyers and 3D indoor profile planes.

  • Wearable Tech & Mini Robotics: An excellent, easily concealable 7.4V power supply for custom cosplay props, animated LED badges, and micro-servo robotic mechanisms.
