Battery Life Calculator
Capacity (mAh)
Current Draw (A)
Voltage (V)
Battery life is calculated from capacity (mAh), discharge current (amps), and voltage. Watt-hours = mAh × Voltage ÷ 1000, and runtime = Watt-hours ÷ Power draw (Watts).
💡
Tip: Lithium batteries should not be fully discharged — keep above 20% to maximise cycle life.
