Purpose and core function Compact fastcharge module built around the 4056 charging IC with an integrated PH2.0 connector for easy attachment of PH2.0equipped battery packs. Thermal regulation for reliable operation across a wide temperature range (40°C to +85°C). Key benefits (why you need it) Simple, spacesaving solution for adding reliable charging to small, portable projects. PH2.0 connector makes installation quick and repeatable; no soldering required if your battery or harness uses PH2.0. Builtin thermal regulation improves safety and stability in extreme operating environments. Important specifications and performance notes Charging controller: 4056 chip (integrated on the board). Connector: PH2.0 for direct plugin connection. Operating temperature range: 40°C to +85°C. Recommended charging current: 0.37 × battery capacity. Example: a 1000 mAh battery → approximately 370–400 mA charging current. Higher charge currents (such as 1 A or 2 A) can be used, but may result in reduced battery voltage after charging. Installation caution: do not force or block the pin/port. Verify connector orientation and polarity to avoid connecting the positive terminal in reverse. Compatibility and use considerations Compatible with devices and battery packs that accept a PH2.0 connector and the charging profile provided by the 4056 chip. Compact form factor fits into small enclosures and portable devices. Designed for practical, repeatable connections; check connector polarity before powering. Typical applications (practical scenarios) Robotics projects that need an onboard, spacesaving battery charger for portable power modules. DIY portable electronics (for example, MP3 players and small media devices) where a compact charger with a PH2.0 plug simplifies assembly. Product prototypes and gadgets developed by engineers who require straightforward, reliable battery management during development and testing. User guidance and precautions Confirm connector orientation and positive terminal alignment before plugging in to avoid reverse connection. Follow the recommended charge current (0.37× capacity) for longer battery life; higher currents are possible but may affect final battery voltage. Use the module within the stated temperature range for safe, stable operation. This module provides a compact, PH2.0compatible charging solution with temperature regulation and a 4056 charging IC for straightforward integration into small electronics and prototype projects.
