i connected 2 18650 lithium ion batteries in series, generating 7.4 volts. i connected the batteries to a buck converter. the input is 7.4 volts. the output current is 1.19 amps. the output is connected to a 2 ohm 200 watt resistor. why is the output current not 3 amps? i tried adjusting the constant current potentiometer, that won't work. i tried adjusting the constant voltage potentiometer, that won't work. why is the output current not 3 amps?
