Capacity testing a battery pack. I'm using a array of 5W 7.5 ohm resistors. I watched the markings on them burn off. I was feeding them 12.5V... I wish I had that on camera. #maker #electronics #LiIon #LiFePO4

Are there "better" batteries than the #Fairphone4 stock battery?
Or should I just buy from #Fairphone official website even though it might be 3 year old tech (at least it's from certified resources)
Recommend me things to buy / read into
#AITA or does the #Fairphone3plus's #battery tend to #bulge pretty quickly?
Cuz I shouldn't be on the 3rd battery when I bought it mere days before it got discontinued...
Made one mistake in my wiring harness. I forgot to add the positive side direct battery string access wire. I may not bother with it. I don't need it yet.
I need to do a second check of the wiring, then I can use it to test my cells.

@tagesschau Ich halte das für falsvhe #Paranoia angesichts der miserablen #Verarbeitungsqualität.
- Viele #Tesla, insbesondere "#Cybertruck|s" sind schlechter gefertigt als der durchschnittlichte #Trabbi.
Hinzu kommen dann tausende Akkuzellen an #LiCo / #LiIon / #LiPo - Akkus welche zum exothermen "Runoff" und damit #Metallfeuer neigen und schon gibt's nen großes Feuer.
- Das wäre kein "#Terrorismus" selbst wenn Halter*in dies (unter rechtsstaatlich unzulässigenBedingungen!) gestehen würde, sondern schlichtweg #Fertigungsfehler.
Deshalb sind Teslas offiziell in viele chinesischen Städten und Autobahnen verboten!
- Zumal die einzigen Leute die sich freiwillig nen "#WankPanzer" wie den CyberTruck oder ein #Trump-#Hotel geben nur #Musk- & Trump-Fans sind!
Ich halte es für wahrscheinlicher dass dies wie der angebliche "#Anschlag" nur ne.weitere #FalseFlag ist, denn für's Abfackeln des Senats hat es anders als 1933 von Budget nicht gereicht...
@CppGuy One word: #Tetraetyllead
- But fear not, when a #BEV's battery has a #ThermalRunoff (cuz they use shitty #LiCo ( #LiPo / #LiIon) and not #LiFePO4) they'll release a white cloud of #FluoricAcid #vapours and then start a #MetalFire that is basically "unextinguishable" (as in the only proven strategy is to throw dry sandbags in it and hope it glasses itself like the #ElephantsFoot from #Chornobyl...
IMHO it'll be inevitable that #Methanol #FuelCell-based #EV|s will be the future simply because:
1.#Lithium is scarce & expensive
2.#refueling will always be faster than #charging
3.#EnergyDensity of Methanol exceeds that of any #battery
4.#FussilFuel #Corporations can simply switchover pumps and flex their #EconomyOfScale and existing #Logistics to flood the market with cheap Methanol even if it has to be made 100% sustainable and without any fossil resources.
5.#EnergyStorage is another problem and #FuelCells can replace both #EmergencyPower systems running if #Diesel as well as the average #gasoline #generator.
Not to mention there needs to be #SystemChangeNotClimateChange and that necessitates way better #PublicTransport, regardless if #Trains, #Trams, #Trolleybuses or #FuelcellBuses (in that order)...
- Otherwise shit won't change.
OFC what any #BEVs won't fix is the fact that most particle emissions are #tire #brake #dust...
- And those are inherebtly unavoidable.unless we want to sacrifice #RoadSafety!
Nice to have some 18650 #lithium #batteries lying around to repair small appliances...

@jon @energisch_ @wmd Problem with #LithiumBatteries (actually only #LiCo / #LiIon / #LiPo, not #LiFePO4!) is that they tend to exothermically explode and gas out hydrofluoric acid when they degraded too far and/or get charged too fast...
- So they copy & paste #FAA & #EASA rules:https://infosec.space/@kkarhan/113548280398064108
It's also why my landlord won't allow me to install a charging wallbox at my fixed parking spot in the garage, because fire safety codes don't allow that - same with a canister of fuel!
- Thus there's no benefit for anyone here to get a #BEV...
Same with Bicycles / Pedelecs in the cellar, tho since there have been thefts I'd definitely not put anything there that has even remotely some value...
Infosec.SpaceKevin Karhan :verified: (@kkarhan@infosec.space)@energisch_@troet.cafe @jon@gruene.social @wmd@chaos.social Trains they charge you an extra ticket and will fine you for fare-dodging.
- Plus most trains providers ban bikes during rush hour *and* dangerous goods (i.e. any reasonable & working #Lithium battery >100Wh may fall under it as well)...
I commuted for years on a train and I'm shure #DB didn't change the better since 2008-2013...

@pandora_parrot yes and besides that I think #BatteryElectricVehicles will also die out again because #FuelCells using #Methanol at ambient temperature & pressure solve the "#charging" and "#battery" problems elegantly.
- Also the huge amounts of expensive #UnfairTrade minerals like #Lithium and #Cobalt as well as poor #FireSafety of #LiIon / #LiCo / #LiPo cells with #LiFePO4 having noticeable lower vapacity and cell voltage makes it less attractive, cuz even if we assume a mere 30% efficiency (on par with naturally aspirated, fully-mechanical gasoline engines) tue #EnergyDensity and #range with #Methanol easily beats even the most expensive and high-tech battery cells, including some hot sodium-sulphur cells that are at ~ 400°C during operation...
Also espechally in the #USA and other places, people usually choose a #car to reach longer distances that have no #PublicTransport, thus #EV's may force them to a healther driving habit and regular stops, but that's seen as really inconvenient because it extends the trip time...

@Nfoonf wird schon passieren, allein weil #Lithium-Batterien ne Fehlentwicklung sind und die schnell zu #DangerPillow|s werden welche dann mit Flussäurehaltigen Dämpfen exotherm durchgehen...
- IMHO ist es nur ne Frage der Zeit bis #LiIon / #LiCo & #LiPo - Akkus wie verbleites Benzin verboten oder wie #NiCd (als #LiFePO4) nur noch in Spezialanwendungen erlaubt werden!
Und #ÖPNV wird halt #Oberleitung nutzen...

Zumal es nichtmals ansatzweise soviel Kapazität gibt wie dazu notwendig.
Stattdessen sind die "#DangerPillow|s" aka. #LiIon & #LiPo-Akkus faktisch #Brandsätze die nur darauf warten durch mechanische Beanspruchung in Entsorgungsbetrieben Brände auszulösen...
Und wenn So'n #Akkubrand ist dies ein hochgiftiges #Metallfeuer das effektich nicht löschbar ist, weil's so heiß ist dass Sand verglast und dann das flüssige Glas wegen der massiven Ausgasungen von z.T. kochender #Flusssäure um sich spritzt sodass Einsatzkräfte effektiv nur die Brandstelle absichern und warten können bis das Feuer aufhört zu brennen...
Dagegen ist nen Dachstuhlbrand oder nen LKW mit gemischten Gefahrgütern in Form einer Liefertour für Einzelhandelsgeschäfte (auch "Wundertüte auf Rädern" genannt) noch entspannend abzuarbeiten.

Die Energieeffizienz eines Lithium Ionen Akkus ist immer wieder Thema der öfftl. Diskussion.
Tatsächlich gibt es dazu bisher nur wenige wiss. ausgearbeitete Messungen. Ich habe mich trotzdem mal durch die aktuelle Studienlage gewühlt. Ein
