When physical space and payload capacity are your absolute strictest design constraints, the 3.7V 200mAh Lithium Polymer (LiPo) Battery provides the necessary power without tipping the scales. Weighing in at approximately 5 grams and featuring a footprint smaller than a postage stamp, this ultra-micro cell is engineered for nano-scale engineering. Despite its diminutive size, it harnesses advanced lithium-ion chemistry packed within a flexible foil pouch to deliver a steady 3.7V output, keeping your miniaturized circuits running reliably.

Because this battery is designed for extremely small applications, it typically comes pre-terminated with a micro-pitch connectormost commonly a JST-GH or Molex PicoBlade (1.25mm or 1.0mm pitch)rather than the bulkier 2.0mm JST-PH found on larger cells. Even with its tiny form factor, high-quality models still conceal a miniaturized Protection Circuit Module (PCM) beneath the top layer of Kapton tape, ensuring the battery remains safe from volatile over-charge and over-discharge scenarios.

Key Features & Functional Advantages:

• Ultra-Micro Form Factor: Provides an exceptional energy-to-volume ratio, allowing it to be seamlessly hidden inside 3D-printed smart jewelry, miniature spycraft enclosures, and compact wearable technology.

• Integrated Safety Circuit (PCM): A microscopic built-in battery management board actively monitors voltage, cutting off the circuit if it approaches dangerous over-charge (4.2V) or over-discharge (3.0V) thresholds.

• Featherweight Design: Weighing roughly 4 to 5 grams, it adds virtually zero mass to your project, which is a critical necessity for maintaining the flight dynamics of indoor micro-drones.

• Micro-Pitch Connector: Ships with an ultra-small, pre-crimped connector (such as a 1.25mm JST), allowing for quick, solder-free integration into compact development boards and micro-flight controllers.

• Rapid Charge Time: Because the total capacity is only 200mAh, the battery can be completely recharged from empty to full in well under an hour using a standard 100mA to 200mA charging rate.

Perfect For:

• Micro RC & Nano Drones: The industry standard power source for “Tiny Whoop” indoor FPV quadcopters and ultra-lightweight micro-gliders where every single gram affects flight time.

• Wearable Technology: Ideal for powering low-profile electronic wearables, including smart rings, fitness tracking wristbands, and discreet biometric sensors.

• True Wireless Audio: Sized perfectly to act as the primary power cell inside custom Bluetooth earbuds and miniature wireless microphone lapel transmitters.

• Ultra-Low Power IoT: An excellent companion for heavily optimized, sleep-mode-dependent sensor nodes (like nRF52 or low-power ESP32-C3 boards) that only wake up once an hour to transmit a burst of data.
