My team is trying to use a power bank to power 2x orange pi 5 for running photon vision on our robot. I was wondering if i could get any recommendations from this platform.
We used these last year with no complaints

How many matches did that last?
I may be misunderstanding something here but keep R601 in mind.
R602 covers extra batteries for computing devices
@Prince I will ask my programmers tonight about that.
You will have trouble finding a power bank that supplies the recommended 4A. Some that provided more then 2A use PD, which Orange Pi5 does not support. That said, your actual load for what you are doing for something like vision may be less the 2 amps and may work. We used a power supply that displayed current use and it was always under 2A for a single camera and no other peripherals running Photonvision AprilTag or object detection.
Ah my bad, I searched “battery” instead of “batteries”
Edit: Technically illegal last year But I wont complain. FIRST should just allow USB PD COTS and call it done. Maybe provide a max POWER limit if they want to create an “even playing field” or “technical challenge” to force the use of lower power coprocessors - but that would do away with making sure your battery bank last year couldn’t go over 5V and this year nothing over 12V capable (many higher end devices negotiate 15V and 20V which would currently violate 2025 R602
I do agree FIRST should just list standard USB power limits instead of these weird limits.
It was legal…ish last year as a Q&A question said that what voltage/amp being provided mattered, not what it could do. As such our PIs couldn’t pull more than 5 volts so it was fine.
Also, I would link the question but I have no idea how to look up old Q&A.
Could you use two battery packs, one for each Orange Pi 5?
You are right!
I remembered a Q&A, couldn’t find the answer, looked up an old thread on CD and looked at some posts I made in jan24’ that concluded that indeed it was illegal - but those posts were before Q177 last year where later in the thread it was detailed that [paraphrasing]:
“packs that would allow higher voltage would be allowed as long as you can prove the negotiated voltage is 5V5A or less”
And because pi5’s and orange pi’s document in their datasheets that they can only accept 5V, all was well last year.
We used 3 cameras on the orange pi 5 and the battery lasted around 4 matches.
Does anyone else have any suggestions?
You can move a bit of the power load off the computers by using a powered USB hub or split data/power circuits for the cameras. Then the cameras get power from their own hub or VRM or other regulator.
We are planning to use a mitocandria but we are worried that with the amount of motors we have planned it might be too much for the battery. So I am mainly looking for any suggestions for power banks that comply with r602 and are proved to work for an frc robot
