This calculator was developed to assist in sizing battery capacity in electric propulsion systems, considering different operating regimes throughout the flight. Based on peak takeoff power, climb power, and cruise power – as well as the usage time of each regime – the tool estimates the minimum required battery capacity in kilowatt-hours (kWh). Based on this result and the selected controller (MIG DRIVE 700 or MIG DRIVE 1000), the calculator automatically indicates the most suitable battery configuration, such as 30S1P, 30S2P, 40S1P, or 40S2P, assisting in technical decision-making and electrical system compatibility.

Battery Sizer — Miglia Lab

Calculates kWh required from power regimes and recommends 30S/40S (1P/2P) based on the EVE M21 59Ah cell.
Version 1.0 (energy)
30S = 111V nominal (3.7V/cell) • 40S = 148V nominal.
All times in minutes. Peak time will depend on the motor.
