Battery Inrush Test

Used 8, 10Omh Resistors in parallel, R_L = 1.25Omh, Current Loaded (ideal) = 4.8A

Channel 1 is Iout, Channel 2 is Vin after the filter, Channel 3 is Vout of the U2 efuse.

Compared to using 22K Resistor, Ideal current 0.27mA

Channel 1 is Iout, Channel 2 is Vin after the filter, Channel 3 is Vout of the U2 efuse.

Vout should increase to 6V to match the load. It’s a bit strange that there is no change once power ris connected.
