Thank you for this video! I purchased from Eiechip on Aliexpress some boards XL4015 5A for charging a lithium battery with two resistors and the output voltage is adjustable but the output current is not following the process shown in your video @ 4:20! Which component could be defective on these boards? The same issue with all 5 boards I purchased.
