Description
Safely charge and protect your rechargeable cells with the highly efficient TP4056 Lithium Battery Charging Module. Operating as a complete constant-current/constant-voltage (CC/CV) linear charger, this miniature board is the absolute gold standard for managing 3.7V Li-ion or Li-polymer cells (such as standard 18650 cells). Equipped with onboard status indicator LEDs, it easily hooks up to any standard 5V phone charger via its Type-C or Micro-USB port.
Crucially, this upgraded variant features built-in dual protection ICs to safeguard your custom circuits from accidental discharge or overcurrent spikes.
Key Features
-
Dual Protection Circuitry: Integrated DW01A and 8205A MOSFET chips shield your battery from over-charging, over-discharging, and over-current faults.
-
Smart LED Indicators: Clear onboard diagnostic lighting — Red LED indicates active charging state; Blue/Green LED flags a fully charged status.
-
Adjustable Charging Current: Programmed by default to output a safe 1000mA (1A) charging rate, which can be modified by replacing the onboard program resistor ().
-
Compact DIY Profile: Tiny footprint with pre-tinned pads, making it highly convenient to fit inside DIY power banks, wireless nodes, and mobile electronics.
