BenderBud,
Please give me information for my study.
- Is the module you are using the same module as the picture I showed?
- If so, what kind of charger (how many watts) is connected to the modue?
Please use this as a reference for your project.
I measured the current consumption with the sketch in the link below and it was average 80mA and peak 150mA. 150mAh or 500mAh battery might be too small.
