Hello,
I’m looking at the documentation to see if the pipower will work for what I need. I have a couple questions that may help me understand.
This application is a Raspberry 3 with peripherals mostly used in remote sites where I will not have access to external power. I need to use the device for 30-60 minutes at a time after which, I can usually recharge it before using again. I saw the pipower and that looked of interest. I have two main questions:
- Because I will be outdoors, I will likely have everything encased. I saw here that there is an “EN” IO pin. Does this mean that if an external switch is off, the Pi will not pull power from the batteries? (and if on it will)? How should this be wired? What voltage would be going through that switch? I would like to put an switch on the outside of the casing that can turn off/on battery power. (is this possible?)
- Is there a way to expand battery capacity? I think it is two 18650 batteries in series? If I were to (for example) get four and put two sets of batteries in parallel than put the two sets in series, would I be able to essentially double the capacity (using a PH2.0, 5P connector in the same way as the original).
