Hope all of you are doing well.
I am developing an IoT device that sends MQTT messages over a TCP layer on a SIM800L. I am facing now a problem. basically, I am using a Li-ion battery but the self discharge of those batteries are from 15% per month (at 40º degrees), what is so much because I need that device for 1 year in a row. I am thinking to use primary cells, such as, Panasonic CR123A (I assume those kind of batteries gives to the circuit 2A burst). However, The nominal voltage of those kind of batteries are 3V, to adjust the voltage to 4.1V I am thinking to use the boost converter TPS63020. Do you think it could be reliable use that kind of schematic to solve the problem?
