I'm trying to create a stand alone battery charger for a single 18650 battery.
For this I created the Schematics and PCB found here.
But during the charging only charges with <1A (differential measured over the sense resistor <20mV/20mohm) instead of the calculated 1.6A in constant current mode with an average voltage of 3.90V.
Is there anything I missed while designing the schematic? Because I supply it currently with a lab power supply of 5V and 5A.
