LM2596S LM2596 DC-DC Adjustable Step-down Constant Current Module

Product details of LM2596S LM2596 DC-DC Adjustable Step-down Constant Current Module
LM2596S DC-DC Constant Current Module LM2596 DC-DC 7V-35V Step-down Adjustable CC/CV Power Supply Module. Charging for lithium-ion batteries: the when the lithium-ion 'voltage is low. I use the constant voltage Charging directly. Due to pressure being too large, leading to the damage. So from the beginning use the constant current Charging. When Charging to a certain, the automatic switch back to the constant voltage Charging.
