8A BMS HX-2S-D20 charge controller for 2x 18650 Li-ion lithium battery

This BMS (battery management system) increases the service life of lithium batteries and prevents short circuits, overcharging, discharging and overcurrent.

The HX-2S-D20 is a charge controller for lithium-ion batteries with a voltage of 2 cells (2S). A charge controller is an electronic device used to control and monitor the charging process of batteries in order to extend their service life and ensure safety during the charging process.
Voltage monitoring: The charge controller continuously monitors the voltage of the battery cells. For lithium-ion batteries, it is important to keep the cell voltages within certain limits to prevent overcharging or deep discharging.
Charging algorithm: The charge controller uses a specific charging algorithm to charge the battery cells safely and efficiently. This can include constant current, constant voltage or mixed charging methods, depending on which phase of the charge cycle the battery has reached.
Balancing: Two cells can be used with this module. These cells may charge or discharge slightly differently over time. A charge controller has a balancing mechanism that ensures both cells are brought to the same voltage to ensure consistent performance and life.
