Lithium Battery TP4056 1A USB-C Charger with Protection

Description

Lithium Battery TP4056 1A USB-C Charger Module with Protection
This TP4056 lithium battery charger module is a highly efficient charging and protection board designed for single-cell 3.7V Lithium-Ion or Lithium-Polymer (LiPo) batteries (such as 18650 cells). Equipped with a modern USB-C input port, this module charges the battery safely up to 4.2V using a standard 1A constant current profile, while integrating dual onboard protection ICs to safeguard against electrical hazards.

* Core Charging IC: TP4056 linear charging controller
* Integrated Protection ICs: DW01A battery protection chip alongside the FS8205S dual N-channel MOSFET switch
* Input Interface: USB Type-C port (along with adjacent solder pads for direct hardwired input power)
* Input Charging Voltage: DC 5.0 Volts
* Full Charge Cutoff Voltage: 4.2 Volts (±1% accuracy)
* Maximum Charging Current: 1.0 Amp constant current (adjustable by swapping the onboard Rprog resistor value)
* Triple-Layer Battery Protection:
* Over-Discharge Protection: Cuts off output when battery voltage drops below ~2.5V to prevent permanent cell damage
* Over-Charge Protection: Halts current delivery immediately when the battery reaches 4.2V
* Over-Current/Short-Circuit Protection: Shuts down output load instantly if short-circuited or if draw exceeds 3A
* Dual LED Indicators: Red light signals active charging; blue (or green) light signals a completed charge cycle
* Output Wiring Layout: Features independent battery connection terminals (B+/B-) and secondary system load outputs (OUT+/OUT-), allowing the battery to power devices while simultaneously recharging
