@GoatsLive may want to give GoldenMateEnergy.com a look-see. GoldenMateEnergy got its start making lead-acid and LiFePO4 batteries for trolling, mobility scooters, golf carts, solar and marine solar, etc. UPS product line is a new one for them, maybe 2 years old. They sell direct from a Shopify storefront and at Amazon.

The packaged batteries are made to drop in for various vehicle applications. BMS is internal to the package.

#LiFePO4 #batteries for #mobility and off-grid solar.

@giggls @ulrichkelber Deren Volumen- und Gewichtseffizienz ist signifikant schlechter als #LiFePO4 und daher eignen die sich nur für großvolumige #USV|s.

@krzym "als jede #Brennstoffzelle" ist fraglich, besonders wenn wir Energiedichte & Kapazität in kWh nehmen.

#Methanol speichert deutlich mehr Energie pro Gewicht & Volumen als Akkus, und nen Tank ist signifikant weniger Leergewicht als nen Akku...

-Ein #LiFePO4- Akku mit 500Ah bei 12V & 25kg Gewicht sind 240Wh/kg. Bei Methanol sind es > 2.000Wh/kg bzw. >1.500Wh/l 1.

Außerdem ist Methanol nicht nur billig sondern auch sicherer im Umgang, umweltfreundlicher im Brandfall und mit existierender Infrastruktur logistisch meisterbar.

  • Gerade als Speicher für elektrische Energie wäre die Methanolherstellung sinnvoll.

Want to learn how to build a powerful yet simple 5000W #Offgrid #solar #system? (It uses #powergrid as backup)

VideoVersion with very tiny batteries already Upgrades to 15kWh #LiFePo4 which lasts around 3 days, IMPORTANT: work with cell vendor that accepts returns because #China likes to mix #gradeA and #gradeB and sell as #gradeA (#eve 280Ah)

Gotta love #LiFePo4 batteries... End of 2022 I ordered a batch of 18650s, and then... my scatter brain promptly forgot about them. They sat in an unopened box ever since.
Just now, beginning of 2025, I stumbled over them, and fully expected to have to dispose of them. Put them into a charger for testing and... they're fine. I'm pretty amazed. Not a battery geek, but... is this normal? 😁

An article from AP News about batteries. Knew it was a big deal in CA and TX. Know #ConEd is building some in substations. Using #Tesla #MegaPack and not #LiFEPO4. ConEd is supposed to be replacing polluting #peaker plants with batteries. Overall, very encouraging. Have to check the article for mentions of #Flow batteries. Long past time for #DDC to wake the fuck up.

@CelloMomOnCars A few days ago I listened to this podcast volts.wtf/p/should-we-put-util . The idea of storage everywhere is compelling. Con Ed is already doing this a bit. Putting batteries in their substations. With software they can make it work.

People in NYC are crazed. They hear lithium and think fire. Screw UL, #LiFePO4 . Old buildings' electrification can be resolved with safe batteries in apartments.

@CppGuy One word: #Tetraetyllead

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!
