I am working on a project where I need to find the power consumption of a few sensors that will run off of a LiPO battery—not too difficult. The problem that I am running into is the conceptual side of how everything I see says that battery capacity is only dependent on the current consumption of the sensors, but not the voltage that they need. To me this doesn't make any sense as surely a device that needs 10mA at 3.3V will need less power than a device with the same current but runs at 5V, correct? If anyone can elaborate on the details behind battery life of a LiPO battery I would appreciate it.
While my question is more hypothetical/theoretical, the details of what I'm using are as follows:
• 2S 2800 mAh 40C
• 4 sensors each with a different active and idle current
• The project aims to be low-power consuming, so the best and worst case for battery life is desired.
Thanks in advance!
