Batteries
#1
I'm using Moode with a Raspberry Pi 3B and a Hifiberry DAC+ADC Pro. Sometimes I take it outside on the porch and run it with a battery. It tends to crash and the logs show a power issue. Actually I've had the same crashes plugged in but it happans much more frequently with a battery. I'm using a Charmast 5 volt 3 amp usb battery intended for charging  cell phones. The official raspberry power supply is 5.1 volts. Does that 0.1 volt difference matter? Anyone know of a better battery for this purpose? I can't seem to find anything online with better specs. I tried using the same equipment with Volumio (I prefer Moode) and it did the same thing. I've got another pi3b with Hifiberry DAC+ADC Pro running rasbian stretch desktop version with icecast and darkice to transmit anything from my audio system and it never fails (though I've never tried that setup with a battery). There seem to be so many possible factors. Does a Hifiberry hat draw more power than others? Do all audiophile renderers use more power than other types of software.

The bottom line question is: Will I get better results with a different battery and who makes the best battery? Thanks.

System crashes are abnormal and typically due to something that is external to moOde software for example bad SDCard, power supply issues, system modifications or 3rd party software installed, other hardware issues, etc.

Reboot and post the Moode startup log.

Code:
moodeutl -l

For sure the RPi isn't happy with its power source. I'd be surprised if an up-to-date moOde install would change this but I've been known to be wrong before Tongue

In addition to the usual voltage/current numbers published for rechargeable batteries, one has to know the battery is a "stiff" power source, e.g., the voltage doesn't droop with high current draw. Some are; some aren't. 

Then there's the USB cable between the battery and the RPi. It should be short and have adequately sized conductors so the voltage drop with high current draw is manageable.

Yep, the dmesg log is the way to see those undervolt events.  I know that (at least some of the Pi versions) the power LED is supposed to flash or change color,  but I swear there have been times I haven't seen that,  and then there were lots of u-v events in the log.

I have had cables be the culprit, with an otherwise OK power supply, on several occasions.  You want one with heavier wires, there are some amazingly thin ones out there,  though this isn't often documented.   Try ones that say they're for charging rather than just data.  If they document that...   A cheap, super thin wire cable will have more drop, as TOP has said, and with enough drop your voltage goes too low. A "5.1V" vs a "5V" would give you another tenth of a volt to lose over a cable, so that would be leeway. If the supply is doing that.

For testing, try the following. It might be worth trying to create as much load as you can, run high bitrate radio, turn on resampling to high bit and data rates, maybe other CPU using features, for a worst case current draw.  Then try swapping different cables in and out, and reading the log for undervolt events.  That's the quickest, easiest thing to do.  
Then try swapping the supplies, with a known "better" cable.  Standard process of elimination process.  Hopefully you end up with at least 2 good cables, throw away a few bad ones, and find both supplies worthy.

Interesting note on the "5.1V" battery.   There is no such thing as a 5.1V battery.  All "batteries" that provide a USB compatible voltage are batteries
(usually single cell Lithium at 3.6V or therabouts) with a switching power supply to bring it up to 5 or 5.1V.  So, you're actually at the mercy of the switcher supply in the battery pack, as to stiffness under load. If well designed, that would be better than a raw battery.  I'd normally ask if you had a decent meter to measure the voltage,  but it's difficult on USB systems, since it's hard to measure at the connectors unless you make an adapter tap cable or something,  and probing on the Pi happens to be very hazardous, in that the convenient spots near the connector happen to be very near places to blow out stuff if you slip.  (Don't ask me how I know!!)  Be careful if you try that.

An aside about these USB "Batteries". This makes me giggle a bit, as a hardware electronics guy,  about people hoping for better "audiophile" effects of running off a battery, but using one of these USB supply packs.  An actual battery is a pretty low noise power supply, if that's going to be important.  USB battery paks invariably have a dreaded switcher, probably built cheap by some mega producer?  Hmmm...  you might be better off with that phone charger.  Or, maybe your modern Hat designer did enough with a decent design, and it rejects normal noisy USB power,  and the "audiophile" needs are satisfied with either?

You just need a well regulated supply that won't sag under your load.  And a solid, low resistance cable that won't drop too much getting it there.

Thanks to Tim and Kent for your replies. I've done many experiments with different power supplies, (The point of the battery was only to use on my porch where the nearest outlet is inconvenient), different sd cards and fresh installs. Did this with Moode and Volumio. My concclusion is that I actually was using a problem raspberry! I changed to a different one and everything has been running continuously with any power source.

(08-04-2021, 07:03 AM)Thanks to Tim,Kent and Jon for your replies. I\ve done many experiments with different power supplies, (The point of the battery was only to use on my porch where the nearest outlet is inconvenient), different sd cards and fresh installs. Did this with Moode and Volumio. My conclusion is that I actually was using a problem raspberry! I changed to a different one and everything has been running continuously with any power source.  JonPike Wrote: Yep, the dmesg log is the way to see those undervolt events.  I know that (at least some of the Pi versions) the power LED is supposed to flash or change color,  but I swear there have been times I haven't seen that,  and then there were lots of u-v events in the log.

I have had cables be the culprit, with an otherwise OK power supply, on several occasions.  You want one with heavier wires, there are some amazingly thin ones out there,  though this isn't often documented.   Try ones that say they're for charging rather than just data.  If they document that...   A cheap, super thin wire cable will have more drop, as TOP has said, and with enough drop your voltage goes too low.  A "5.1V" vs a "5V" would give you another tenth of a volt to lose over a cable, so that would be leeway.  If the supply is doing that.

For testing, try the following.  It might be worth trying to create as much load as you can, run high bitrate radio, turn on resampling to high bit and data rates, maybe other CPU using features, for a worst case current draw.  Then try swapping different cables in and out, and reading the log for undervolt events.  That's the quickest, easiest thing to do.  
Then try swapping the supplies, with a known "better" cable.  Standard process of elimination process.  Hopefully you end up with at least 2 good cables, throw away a few bad ones, and find both supplies worthy.

Interesting note on the "5.1V" battery.   There is no such thing as a 5.1V battery.  All "batteries" that provide a USB compatible voltage are batteries
(usually single cell Lithium at 3.6V or therabouts) with a switching power supply to bring it up to 5 or 5.1V.  So, you're actually at the mercy of the switcher supply in the battery pack, as to stiffness under load. If well designed, that would be better than a raw battery.  I'd normally ask if you had a decent meter to measure the voltage,  but it's difficult on USB systems, since it's hard to measure at the connectors unless you make an adapter tap cable or something,  and probing on the Pi happens to be very hazardous, in that the convenient spots near the connector happen to be very near places to blow out stuff if you slip.  (Don't ask me how I know!!)  Be careful if you try that.

An aside about these USB "Batteries". This makes me giggle a bit, as a hardware electronics guy,  about people hoping for better "audiophile" effects of running off a battery, but using one of these USB supply packs.  An actual battery is a pretty low noise power supply, if that's going to be important.  USB battery paks invariably have a dreaded switcher, probably built cheap by some mega producer?  Hmmm...  you might be better off with that phone charger.  Or, maybe your modern Hat designer did enough with a decent design, and it rejects normal noisy USB power,  and the "audiophile" needs are satisfied with either?

You just need a well regulated supply that won't sag under your load.  And a solid, low resistance cable that won't drop too much getting it there.

@dmozell - A very good discussion on the pitfalls in powering low voltage devices especially in the context of the current practice of powering devices from USB 5v supplies.

I have encountered problems with USB Cables for several years now, ever since the supply requirement went up to 2.1Amps. I have given up on trying to buy USB cables to use in Charging or Power Supply applications and now treasure my accumulated collection of cables that came with original equipment.

I have disected many cables and have discovered that most of the cable is NOT Copper but CCA (Copper Clad Aluminium)! This is ductile enough to be drawn into very fine and then stranded wire which is usually crimped at the ends. This is even more common in Cat5 and Cat6 patch cables with IDC terminations. Whereas it is possible to solder CCA wire, you have to be careful not to scrape the conductors because if you do, it will expose the Aluminium core which oxidises to a black mess when it comes in contact with activated Flux. Having said that, I have managed succesfully to solder CCA by carefully stripping the insulation and soldering very quickly with a good Rosin cored Solder.

As an aside, If you examine the connections from the incoming BT Cable to your Master Socket, you will probably find that the incoming Pair is crimped using "Jelly" (Gel filled) Crimps to a short pair od tail befor connection to the Master Socket A & B Terminals. I believe this to be because BT installed a lot of Aluminium cable in the 70's and 80's which corrodes very quickly when in contact with other metals and moisture.
