TP4056 3.7V Lithium Battery Charging Protection Module 1A PH2.0 Terminal Power Module Type-C Over Charge/Discharge Anti-reverse

Features:1. Supports Type-C input, compatible with mainstream mobile phone chargers for convenient connectivity.2. Built-in dual protection against overcharging and over-discharging ensures safer usage.3. Dual-colour LED charging status indicator for user-friendly operation.4. PH2.0 battery connector features reverse polarity protection, effectively preventing incorrect polarity connection risks.5. Suitable for 3.7V lithium battery charging modules, widely used in portable electronic device power management.Parameters:Input Interface: Type-CBattery Interface: PH2.0Input Voltage: 5VCharge Cut-off Voltage: 4.2V ±1%Maximum Charge Current: 1ABoard Dimensions: 2.6 × 1.6 cmNotes:1. This module is designed for 3.7V polymer lithium batteries or 3.7V polymer lithium battery packs.2. The charging port can draw power from a USB Type-C source.3. The red LED illuminates during charging; the green LED indicates a full charge.4. The module will generate heat during charging. A noticeable warmth, sufficient to feel hot to the touch, is normal.5. Recommended charging current is 0.37 times the battery capacity. For example, a 1000mA battery requires approximately 400mA. Higher currents (1A or 2A) may be used, though this will result in greater voltage drop upon completion.6. The 2-pin port effectively prevents reverse polarity connection.7. Solder pads are retained for convenient DIY modifications.Packing list:Lithium battery charging module12-pin terminal cable1
