Inductor: AGP4233-473ME (100khz) or -683 (50khz), larger
Lower frequency → higher efficiency (less switching loss), more mass (larger coils)
Other simpler components in spreadsheet, seem feasible.
~4 mOhm at 7.5V

To investigate: not using a multiplier
Potentially via output current sensing?
Battery should keep (in a short timeframe) stable voltage, so sensing the output current would give us a proxy for power
Next steps:
Create schematic
