3.7V 1000mAh Lithium Polymer (LiPo) Rechargeable Battery

When building portable electronics, finding a battery that holds enough charge to be useful without being too bulky to fit in your enclosure is often the biggest challenge. The 3.7V 1000mAh Lithium Polymer (LiPo) Battery solves this dilemma perfectly. It holds five times the energy of ultra-micro cells, providing hours or even days of runtime for custom microcontrollers, yet it remains incredibly thin and lightweight. Encased in a flexible foil pouch, this lithium-ion cell delivers a reliable 3.7V nominal output, making it the undisputed go-to power source for standard 3.3V and 5V portable projects.

Safety and ease of use are paramount with this cell. Beneath the Kapton tape at the top of the battery lies a miniature Protection Circuit Module (PCM). This built-in battery management system acts as a vital safety net, automatically cutting off power to prevent dangerous over-charging (above 4.2V), deep over-discharging (below 3.0V), and accidental short circuits. Furthermore, it typically ships pre-terminated with a standard 2-pin JST-PH 2.0mm connector, allowing you to plug it directly into popular development boards and charging modules instantly.

Key Features & Functional Advantages:

• Optimal Capacity-to-Size Ratio: Provides a full 1 Amp-hour (1000mAh) of energy storage while maintaining a footprint smaller than a credit card and roughly as thick as a few stacked coins.

• Integrated Safety Circuit (PCM): The built-in protection board ensures the battery remains safe during operation and charging, preventing permanent chemistry damage and fire hazards.

• Standard JST-PH Connector: Comes pre-crimped with the industry-standard 2.0mm pitch JST connector, ensuring immediate plug-and-play compatibility with Adafruit, SparkFun, and custom power shields.

• High Energy Density: Utilizes advanced LiPo chemistry to deliver consistent, flat-curve voltage output, keeping your electronics running optimally until the battery is nearly depleted.

• Easy Recharging: Pairs perfectly with standard 1A linear charging modules (like the TP4056), allowing for a safe, complete recharge from empty to full in approximately one hour.

Perfect For:

• DIY Portable Gaming: The absolute standard battery for powering custom Raspberry Pi Zero handhelds, retro emulators, and custom Game Boy mods.

• Wi-Fi & Bluetooth IoT Nodes: Provides ample power to sustain the heavier current spikes required by ESP32 and ESP8266 boards transmitting data over Wi-Fi networks.

• Custom Audio Devices: An excellent, long-lasting power source for DIY Bluetooth speakers, portable headphone amplifiers, and digital synthesizers.

• Wearables & Cosplay: Thin enough to be hidden inside electronic badges, 3D-printed gauntlets, and LED-illuminated props without adding noticeable weight.
