1A LIPO BATTERY CHARGING BOARD MICROUSB TP4056L

Description

A compact, USB-powered charging module for single‑cell (3.7 V nominal) LiPo or Li‑Ion batteries. Built around the reliable TP4056 charging IC with integrated protection (DW01), it offers efficient CC/CV charging up to 1 A, complete with safety safeguards and LED status indicators.

Key Features:

Precision charging using TP4056: CC/CV mode, up to 1 A, with ±1.5 % accuracy, automatically terminating at 4.2 V.

Integrated battery protection (DW01): guards against over‑charge, under‑voltage (<2.4–2.5 V), over‑current (≈3 A), and reverse polarity.

Thermal and current protection: limits current below 1 A if input exceeds ~5.2 V; operates safely across –10 °C to +85 °C

BATTERY CHARGING BOARD MICROUSB

Adjustable charging current: change the resistor to reduce current (useful for smaller cells)—often set to 0.37 C.
