Re: Viability of using a USB power bank as a UPS?

Nazo:
I feel your pain. For a simple solution that can communicate low battery and manage power-outages,
check out: http://www.lifeguardsolution.com/

It can communicate via GPIO to alert your system of power loss. It can also monitor a "Heartbeat" to ensure the SBC is running.

Re: 12v UPS DIY Help

Sora03: You just described our solution. We struggled with remote installations in the field, providing clean power, battery backup, and sending a GPIO signal to alert the system of a required shutdown. When the batteries recharge, power is restored and the system boots. It's great :) If you are int...

Re: Battery

SayWut: We had a similar concern for remotely installed systems. Our solution was to create a smart battery-power system, which can communicate to the SBC via GPIO. When the battery power drops, a signal indicates to the SBC to shut down clean. When the batteries recharge, the controller automatical...

Re: How to convert 3.7v battery to 5v?

We had a similar issue with reliable power at remote sites. We needed to ensure up-time without corruption due to power outages. Our solution was to create a smart battery system that can communicate via GPIO. For additional information see: http://www.lifeguardsolution.com/ I hope this helps :-)

Re: Raspberry Pi UPS with Auto Restart

Power states and Heartbeat signals communicated via GPIO pins. We recognized the same potential power problems with SBC’s (Single Board Computers) like Raspberry about a year and a half ago. Our solution is simple: Create a power management controller to manage battery and computer uptime. It works...
