The TP4056 1A Li-Ion Lithium Battery Charging Module without protection is a simple, cost-effective linear charging solution for single-cell 3.7V lithium-ion or lithium-polymer (LiPo) batteries.
The TP4056 1A Li-Ion Lithium Battery Charging Module without protection is a simple, cost-effective linear charging solution for single-cell 3.7V lithium-ion or lithium-polymer (LiPo) batteries. Built around the industry-standard TP4056 standalone linear charger IC, this module safely manages the complete charging cycle using a Constant-Current/Constant-Voltage (CC/CV) charging algorithm.
Powered conveniently via its onboard Micro-USB Port or external solder pads (IN+ and IN-), it delivers up to 1A of charging current (preset via an onboard programming resistor) to charge 18650 cells, pouch batteries, and custom battery packs. Onboard dual-color LED indicators provide real-time status feedback (Red for charging, Blue/Green for charge complete).
This basic, non-protection version is ideal for applications that already feature built-in battery protection circuits (BMS), custom battery shields, or direct microcontroller prototyping setups. It connects easily via through-hole solder terminals (B+ and B-) and is fully compatible with Arduino, ESP32, ESP8266, Raspberry Pi Pico, DIY power banks, and portable electronics.
