I'm not sure about JetCat but Kingtech ECUs has a way to see how many mah have been use (total) from the first time of use after the batt has been fully charge, the next time the batt is charge before the first flight the meter can be reset to start counting from zero, I thing I will be using that to double check my findings when recharging the ECU batt.
