Lipo Battery 601633 300mAh - 3.7V Rechargeable Lithium Polymer Cell with PH2.0 2Pin Connector, for DIY Electronics & IoT Devices

The Lipo Battery 601633 300mAh with PH2.0 2-Pin Plug is a high-performance, ultra-compact rechargeable lithium polymer power source engineered specifically for makers, electronics hobbyists, and DIY engineers. Designed to fit into tight spaces where conventional battery packs fail, this cell delivers a dependable 3.7V power output ideal for low-power microcontrollers, wearable technology, wireless sensor networks, and portable gadgets. Whether you are powering a custom IoT node, a miniature remote control, or a compact robotics project, this battery offers a dependable balance of capacity, safety, and physical footprint.

At the core of this power unit is a lithium polymer chemical composition known for its flexibility in shape and high energy-to-weight ratio. The battery features an integrated Protection Circuit Module (PCM) situated discreetly at the terminals. This crucial safety circuitry actively monitors voltage thresholds to prevent catastrophic failures caused by overcharging, excessive current draw, or deep discharge scenarios. The output is terminated with a standard industry PH2.0 2-pin connector, eliminating the immediate need for soldering when connecting to compatible development boards, breakout modules, and miniature charging circuits. The 601633 designation defines its physical envelope of approximately 6mm thickness, 16mm width, and 33mm length, though slight dimensional variations may occur depending on specific manufacturing batches and protective shrink-wrap tolerances.

This rechargeable lithium polymer battery is exceptionally well-suited for a wide array of DIY electronics and embedded systems. Common use cases include powering ESP8266 or ESP32 based ultra-low-power IoT sensors, wearable health monitors, miniature drone receivers, custom Bluetooth peripherals, portable test instruments, electronic toys, and backup power supplies for real-time clock modules. Its compact geometry allows it to be embedded seamlessly inside 3D-printed enclosures and wearable bands.

When integrating the Lipo Battery 601633 into your projects, always ensure your charging circuit is properly calibrated for single-cell lithium polymer chemistry, typically utilizing a dedicated charge controller IC such as the TP4056. Verify the polarity of the PH2.0 connector against your target board before plugging it in, as pin assignments can occasionally vary between different hardware manufacturers. Never puncture, crush, or expose the battery to extreme temperatures, and store it at a partial charge state if unused for extended periods to maximize operational lifespan.
