          I’ve been testing with Mayfly 1.1 and LiSOCl2 D batteries. Our package is using a Mayfly 1.1, and SD card, and a sensor on the switch power that pulls ~350 mA in pulses when its on.

          I initially

            @khaase  interesting getting the LiSOCL2  activated.

            My 2Cents is it would be good to characterize the 350mA  pulse – and isolate it from the mega1284’s  high impedance LiSOCL2.   T

              So far, your super-capacitor idea is holding up pretty well for me. A 100 uF capacitor buffered voltage sag to a degree, but the 10,000 uF supercap (1/10 the voltage rating and 1/2 the physical size)

                @khaase great to hear  – do you have a pn for the cap – be interested see what the internal ESR is.

                Seems to me a way to monitor the battery for maximum life is to read the voltage unloa
