Yeah the DIP switches just configure the power bank SMPS control chip, not the BMS. RIP. I'll have to leave a review for the aliexpress listing warning people of this.
>Some chargers have series discharging buck. One provides the maximum voltage negotiated, one just lets that through, others negotiate something and provide that.
Seems kinda shitty, I know some wall-chargers turn off power and renegotiate on replugging something else, but I bought a 140W GaN one that doesn't do this. I'm fairly sure I've used power-banks that don't either, but I'm not certain. Ideally I think it would have an H-bridge buck-boost converter for each USB-C port, and a buck converter for each USB-A port. Maybe buck-boost for the A ports too, if you want to support QC4. I know there are PMIC chips that act as multiple switching controllers all at once, so it's probably worth hunting about for a power-bank IC that can do that too.

AAA I HATE IT
I think I'll cool my head off with an analogue audio project for a week.

>You said bad
It's bad if you've got a watt-hour of capacity or less. 10 watt hours and it might be an issue, depends on storage period. The DC power negotiation protocol is intended to be used for 5-50V 0-50A, on things like deep cycle batteries and ATX power supplies and such. Hence why using an ESP32 to talk CAN isn't really an issue. Plug in, battery says it can provide up to 30A, and its voltage ranges from 11-13V or so, with no voltage or current regulation. Soldering iron load says it will draw up to 3A at 13V and to activate the MOSFET, and the battery complies. LED strip says it wants a constant-current signal, battery can't do that so it stays off, same for amp that wants exactly 12.0V, etc. I wanted to use 7W2s so I bought like $60 of them, but the allure of bidirectional battery charging guides me to andersons.
The power-bank is really too small for this kind of protocol, but it might still be handy to have that option.

So I'm just testing this.
Got a 10K pot so I can simulate realistic source impedances and also extreme cases.
10R current shunt.
Datasheets say my FETs are good to 40V, IP2368 can take 30V, wants less than 25V and more than 4.5V.
Starting at 5V and 10K and no advertisement.
Nothing.
Turn the 10K way down:
The board starts to charge. It will indicate normal charging. It draws a continuous 20mA, and pulses the charging functionality on and off (not the inductor, the actual charging) and go from said 20mA up to 80mA and back again. 1s on 2s off. Switching frequency looks like only 3kHz. Same behaviour at 6V. The voltage across the board breaks down from. 5.3V (remember the 20mA standby) to 4.3V or so. So I figure if it undercuts the DS limit of 4.5V after a time it UVLO and tries again.
So it can do. meaningful charging at very low power levels. And it wont even jhst give up and flash an error code but pretemd its charging the whole time, even when its recovering from suspected
UVLO.
At 7V through a 10R and the 10K pot all the way to minimum (it's not zero power goes up 50% when shorting) the charging commences steadily with the voltage across the board at 4.4V, drawing 120 mA in total.
Last datapoint: Shorted 10K, PSU at 7V, so only 10R left. It now draws 150 mA and the voltage remains pinned at 4.4V
So from this I deduct that, when supplied from a load with a current lit below the boards configured limit (1A i to battery I have confirmed) it regulates so that it just barely violates it's 4.5V lower limit. Below that there's probably an RC relaxation oscillator happening somewhere.
So all hypothesis confirmed, I guess:

Oh, neat. 4.5V seems like a sensible threshold, considering USB chargers will try to output 5V, but I suspect some USB chargers will start hiccoughing before going down that low. Try adding resistive dividers to the D+/D- pins of a USB C port, assuming it even looks at those. That might trick it into trying to draw more or less current. I suspect 4.5V isn't a very good MPPT level for your dynamo either way.

>>2969752
Like hell that thing is rigid enough to do anything. I tried a smaller rotary tool much closer to the gantry of my ender 3 with reinforcing tie-rods, granted it's running on V-rollers and still had bed-springs, but the flex was too much even for precise 0.7mm PCB drilling operations. What's the stepper in the background doing?

>>2969755
>4.5V is sensible
>considering USB chargers
with USB chargers, unless they are dogshit unregulated china slop house butner people electrocutors, I would expect to see the standardized voltages and currents along with advertisement and negotiation on the output anyways.
This is still about the scenario where: Any DC source in - > charge. Judging by how it's operating you could probably even charge of any >4.5V DC source that is limited to >2mA, if you added a large cap. The cap would just charge through whatever exceeds the 2mA quiescent current and once it hits 4.5 the charger would kick in for a bit. It's what I believe is happening anyways with the chargers cap.
>MPPT level
The dynamo. is everything but a purely real source and it likes to go to 70... 80... 90V when open and fast. But I can check the series resistance regarding matching that. It's the other stuff I'm working on.
>Rigid enough.
I think it works quite well, with the zip ties, in the capacity I am using it.
>Smaller rotary tool
I gave this cutter almost no tip at all.
>Stepper in the background
It once provided motion capability for aome control loop testing and is tied to that stand ever since and until it's needed.

Go big or go home. Only one you need.

Nothing happened to the guy I'm going to mention but I hope he reads it. My one roommate had a tendency to invite suspect randoms over to our place without telling anyone. Get home one day and some jackass is parked in my spot in the garage with his car jacked up, I forget how but he might have well been using twigs. He was seating his ass off laying right under the wheel with the tire off using a long jack to pry something loose with the force of an ape. The whole car was wobbling and if it tipped (which looked like an 90% chance) this retard would have died right there in the garage. I told him dude what you're doing is insanely dangerous. I got dismissed and he kept going. I hope you see this and haven't darwin'd yourself you goddamn moron.

>stupid to not have UVLO
I will also say it again:
It depends. It depends on what you're doing and what your requirements are. If for example your application means it is inherently impossible for the batteries to be discharged to anywhere near low, then guess what:
You do NOT NEED UVLO. Instead it might only mean additional points of catastrophic failure.
Secondly: UVLO alone is NOT a BMS. I'm not going to attempt a defi ition of 'BMS' vut it is safe to say a BMS needs to incorporate at least two of the typical functions:
Balancing, UVLO, OVLO, OCLO etc.
If it's a standalone solution that provides only one of those functions it is hardly a 'system'.
But I've already complained above how 'BMS' muddies the water and for some it's all the same and you NEED to have one.

>>2969540
>If for example your application means it is inherently impossible for the batteries to be discharged to anywhere near low, then guess what:

If you are using a lithium battery and you are, somehow, absolutely certain that it can never be over-discharged, over-charged, operated below freezing, experience overcurrent, or go out of balance...good on you. You have some incredibly niche application that represents a vanishingly small portion of the market. Everyone else is better off erring on the side of caution.

Especially when considering the "out of balance" thing. The only packs that aren't really at risk of this are made of extremely expensive, well-matched cells. In other words, the cost of the BMS is trivial in comparison when protecting pricey equipment. Conversely, if you DON'T have such high-quality cells, the BMS becomes much more necessary because they're more likely to have problems.

>>2969545
I think there is a misunderstanding on at least one side and I don't feel it's worth further pursueing the discussion.

>>2968771
>It's reddit tier cargo cult to 'always NEED a BMS / balancer / over- under- etc. - protection'
When does an ESS LFP battery NOT need a balancer and over/undervoltage protection and overtemperature protection? In what scenario is it better to save the $100 and use raw LFP cells without each of these functions?

>>2969561
Fine, I said it more explicitly in another thread:
There exists a group, who, every time a battery is mentioned, talks about house fires, explosions and the requirement to use a non-descript 'BMS'.
I would bet that, ironically, the same people do not have a solid voncept of what a BMS is, how several BMS can differ vastly in features and performance and especially under what circumstances which of those features a BMS can have are required - or not. Let alone would I believe those people understand how those features are implemented or trust them with implementation itself, be it using discrete comparators and FETs or one of the usual one stop shop ICs.
This usually then leads to those people, buying any object that id labelled 'BMS' by chang the vendor and perhaps their buying decission is influenced by something they have heard 'is somehow more better... it has a transformer, or inductors or caps...'.
They will then unironically hook up a 5A balancer to a bunch of series 18650s 'because I am building a 5A pack' and call it 'a BMS'. Meanwhile their application is one where they'd probably be nest advised to slap some dumb Rs on and discharge overcurrent protection and be safe.
So in short: The common was not aimed at the narrow scope of stationary, low maintenance, PV 'house' batteries.
And in any case: Yes, bare cells are not consumer products. People should have understanding of what they are doing and not read some whacko opinions online, be full of themselves and just imitate what they saw or heard. That is cargo cultism and at least stupid.

Thats it for now, the flower spike will start to die out over the next couple of months but will remain on the plant, then in a few years time itll grow another flower spike along side the old one like in this picture

Spent a week on KI this year and learned that one of the first industries on that island was exporting the red gum/resin they harvested from these grass trees. It was used in myriad products from food and clothing (dye) to cosmetics and fireworks. Downside being they had to smash the dried trunks into tiny pieces for the resin to fall out and nearly drove the local population of Xanthorrhoea to extinction. They called them yakka trees back then and it was a punishing, painful and labor intensive job which is where the term "hard yakka" comes from meaning hard work. Saw a few dead/broken grass trees on my walks there, the amount of resin inside is pretty astonishing, there's lots of it. You can still buy the stuff today.

Alternatively you can always scrape some soldermask off the trace that went to the pad and either bridge it with solder or a jumper wire. But the diode being that close it's a no brainer.
Regarding heat: If anything that joint was too hot, at least I cant think of anything that let's the pad come off the board so easily.
To solder: Generally touch your iron to both the part and pad, add a quick dab of fluxcore solder (you're really adding flux here) it will improve heat transmission. Always think of heat capacity and also thermal insulation of parts. Shortly after add the remaining solder. Wait briefly and remove iron.
That is for general soldering of fairly sigeable and insensitive parts.
Look up how the look of a solder joint reveals issues like cold joints, cooked joints, too little flux etc.
Have flux handy, mane forget about it but the flux core solder might not always be enough.
Practice, practice, practice.
