Hi everyone,
I recently came across this article:
An Article to Understand Portable Power Station — https://easyelecmodule.com/an-article-t ... r-station/
and thought it might be useful for anyone powering a Raspberry Pi from a battery or solar source.
The article explains the roles of the battery, inverter, and BMS in a portable setup quite well, and it got me thinking about how these ideas apply to Pi projects — especially off-grid systems, UPS units, or mobile data loggers.
Here are a few points I’d like to discuss with the community:
Voltage stability: Has anyone run a Pi 4 directly from a power station’s 5 V USB output? Some of them dip slightly under load — curious about real-world results.
Deep-discharge protection: The article mentions about 2.7 V cut-off per cell. In LiFePO₄ setups, I’ve had better longevity using around 3.0 V. What do others use?
Solar recharging: The piece mentions 3-hour full solar charging in ideal conditions, but in practice it often takes longer. What kind of solar input times are you seeing in Pi field projects?
Efficiency: For longer runtime, have you noticed improvements by powering your Pi directly from DC rather than through the inverter?
Temperature and ventilation: Portable stations can heat up under load. Has anyone logged internal temps or used the Pi for automated thermal monitoring?
A few open questions:
What’s your ideal portable power setup for a Pi used in the field (monitoring, cameras, or IoT)?
How do you store your batteries when not in use — 50 % charge or full?
Has anyone tried integrating the Pi with the station’s BMS over I²C or UART for data monitoring?
The article is a solid reference point for understanding how portable stations are built, and I’d love to see what solutions other Pi users here have tried in their own projects.
