Greetings everyone. I have a question to ask.. This is a remote control from a wall mounted fan. It uses a 3V coin battery. I replaced it with a 3.7V LiPo battery that I savaged from a used vape. I added two circuit boards: The one on top is a mini adjustable step down converter and the one on the bottom is a USB-C battery charger (with all the protections and protocols for the battery) the thing is, it keeps discharging without even using it.. is there any way to keep the battery full?
