@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 unloaded, and then again when it is loaded.  The capacitor moderates the voltage reading, but still droops. So it would be how much droop (lack of charging from high i…[Read more]

@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.   That could mean that for the “high impedance” (for a battery)  LiSOCL2,   the current draw has to be kept below a threshold, treated as a constant current source.…[Read more]

Hi @khaase I haven’t figured out what the source of the reset is, as the AVR1284 Arduino code discards it – very frustrating.

I have used low ESR capacitors – something like Digikey 732-9079-1-ND CAP ALUM 680UF 20% 10V THRU HOLE LOW ESR

Whenever I have longer wires, a power switch, or current measurement, with the LiIon battery, I get some…[Read more]
