Five Tp4057 1A Lithium Ion Battery Charging Modules With Type C Usb Hookup Overtemp Cutout And Dual Led Status Lights For Plug And Play Power Setup On Solid Diy Tech Project Rigs

Pack of Five TP4057 Li Ion Chargers With Type C Hook Up
✔️ 1Amp Linear Charge 3 7V Cells Hit 4 2V Full Guard Mode

These five TP4057 charging boards give makers a reliable way to refill single cell lithium cells from standard DC sources. You will drop them straight into flashlight rigs, robot builds, or portable electronics where steady power flow matters most.

✅ Constant current voltage curve keeps cells safe during refill cycles
✅ Over temperature cutout stops the board if heat climbs past eighty degrees
✅ Soft start circuit blocks sudden current spikes when you snap in the cell
✅ Dual LED panel shows active charge state and flags any wiring problems before they fry components
✅ Wide input window accepts four point two volts through six point five volts for flexible power feeds

💡 Why pick specialized charging modules over raw power adapters for DIY battery arrays?
Steady current regulation prevents cathode degradation during rapid top ups. These handy setups handle voltage balancing automatically.
- Overtemp cutoff shields components when ambient heat crosses sixty degree thresholds during fast fill cycles
- Soft start logic caps inrush current so trace paths stay stable under sudden ground shifts
- Onboard LED tracking lets technicians isolate bad cells before they drag down main controller voltage
