At the most inopportune moment, the XL4015 step-down converter burned out. The unusual failure initially threw me into a stupor. For a long time, I could not find what burned out. The voltage was normal, but the current was not regulated. The redesigned batteries for 1865 with a BMS board inside did not charge.
