What's New

v26.05.2

In this update: - Battery life calculator. Estimates runtime of a battery pack from its chemistry, cell configuration, capacity, depth of discharge and load. Advanced mode additionally accounts for internal resistance, C-rate, Peukert exponent and energy conversion efficiency, and plots the discharge curve. - [PRO] Series and parallel connection calculator now accounts for component tolerance. Select an E-series for each resistor, capacitor or inductor to see the minimum and maximum of the equivalent value. Entered components are also kept between application relaunches. - [PRO] PCB trace width calculator now also shows the trace cross-section area and the minimum via diameter and barrel area required to carry the same current. - Unit Converter now supports angle and torque measurements. Big thank you to everybody who subscribed or purchased the app's PRO version. Your support helps to make this app even better. If you like this app, please rate it and leave a review. Regards, Rostyslav
