Bookworm 6.12.y for the uConsole and DevTerm

The battery indicator should be manually calibrated

Charging to full right now, then I’ll follow Rex’s instructions from waaaaay up this top to calibrate.

It’s a pair of 2000mAh 18650s. I checked the connections and they feel like they’re good. I’m going to calibrate, then do some more diagnostics. I feel like the batteries should last longer than 30 minutes with the AIOv2 radios on but not actively in use and longer than about an hour with the radios off. But I suppose I could be wrong, LOL.

If the batteries are fully charged but only last 30 minutes, I doubt this is a calibration issue.

The voltage of batteries with a nominal capacity of 2,000 mAh will likely drop off too quickly.

Do you know the batteries’ maximum current rating?

Kernel has now been updated to 6.12.85 to fix the copyfail vulnerability.

Will Trixie be getting that too?

Yep, just apt update and upgrade and you’ll get the new kernel. I was just posting it somewhere but it’s for all my Debian based distros.

I don’t know if was checking the battery connections, removal and reinsertion of the batteries, or the calibration process, but the issue is fixed! Thanks for the suggestions!

Darn, I spoke too soon. It took hours for the batteries to run down while calibrating but just now shout down with them at about 75%.

Do you use a CM4 or a CM5?

How many hours did it run?

is it me or bookworm is still the best of the bunch for general speed?

afaik they all use the same kernel, so any performance differences are just the default running programs that can easily be changed

same issue, had to use RPI Imager

Loaded 6.12 on my Devterm Pi4 and the screen is upside down, assume I will ened to edit config.txt to resolve, unless this is a different issue.

I just ran it down again today. It clocked in somewhere between 90 minutes and 2 hours (I didn’t catch exactly when it shut down). When powered back up, the battery indicator had it at 78%, IIRC. Interestingly, when I’ve set it up to calibrate, it runs for 3-4 hours and the battery indicator drops as one would expect, shutting down at under 10%. I’m currently eagerly awaiting the HG upgrade kit with the ā€˜blank’ battery/SSD board and am going to switch over to a 10,000mAh battery. It’ll be interesting to see if that makes a difference in how it performs under normal (not calibrating) conditions.

I was using 10,000 Mah batteries but switch to 18650 because the LiPo could not handle the power draw from the uconsole

There are several threads on this topic. In summary, 18650 batteries can handle significantly higher loads without the voltage dropping. If the voltage drops too early, the uConsole shuts down.

You can try to increase the load capacity by connecting multiple LiPo batteries in parallel, but I’ve come to the conclusion that high-quality 18650 batteries are the most reliable solution.

I am running the stock back cover, so I can only fit one pouch in, and I have resoldered my battery holders and removed the jumper to return to using 18650
