TP4056 MT3608 Li-ion Lipo BMS Charger DC-DC Boost Converter micro USB

This model is designed for charging lithium batteries, using constant current / constant voltage (CC / CV). It has no overcurrent and short-circuit protection, we do not recommend using it with a battery that does not have integrated protection.

Constant current control and constant voltage for charging the connected lithium battery
Overvoltage protection - the module will safely charge the battery up to 4.2V ,
Recharging (battery reconditioning) - if the voltage level of the connected battery is less than 2.9V, the module will charge with a current of 130mA until the battery voltage reaches 2.9V again, while at this moment of charging the current increases from linear to configured charging current.
The module includes two LEDs. The red LED indicates charging. The blue LED indicates a complete charge.
