Did we ever see any prices for those bigger 560Ah cells?

Per EVE: The LF-560 will be released for Public Sale Q4-2024.
Dimensionally, they are almost 2x the size of a 280AH. A 16S Case will be suitable for 8S with the larger cells.
They also weigh in at 11.3kg ea making an 8S = 90.4Kg/199.2Lbs and a 16S = 180.8Kg/398.6Lbs + Case, BMS etc on top.
I don't see anyone Wall Mounting a 400 Lb Battery Pack and Telecom/Server Rack, well I wouldn't hold my breath.

Big Cell HEAVY Pack solutions will come and be quite different I think.
- Floor Model Cases on casters
- 4 point rack with shelves screwed front & back @ 4 corners.
- Chest Type packs (cases).
- Other Creative Solution ? going to be interesting I think, when the creative juices get flowing...
 
I would have thought a thick molded plastic case (ice chest type thing) would be a good idea with a single PCB busbar with integrated balance tracks and temperature sensors that just gets bolted to the battery terminals.
Then the BMS, breaker and connections get mounted into a front panel that then slots into the front of the plastic molding and then you screw down a lid that holds the whole lot together.

will the cells be x2 the price of a 280Ah cell?
They sound like a great solution for a DIY 8s pack, not so much for a 16s.
In stationary set up, the weight doesn't seem to be much of an issue really, building a solid support system is just a design exercise.
I wonder how these would be packaged for shipping - one cell per box? LOL.

So to stay dependent/hostage to Big Foreign Oil that changes prices at any issue while making record profits like never seen before,
To relinquish the Freedom & Independence of having a vehicle that you can charge at home and use without dependence on the outside forces in our world.
How nice of you to support the Arab Billionaires and their Cohorts but then maybe you have Stocks/Bonds & Shares in various Big Oil Corporations or you may also be enslaved (working) for them too... GOOD FOR YOU Keeping your Dealer Rich for your addiction while staying a Voluntary Hostage to them...

Here's something to ponder... as the World gets less & less stable and conflicts increase, just how long do you think you'll be able to afford Petro Fuels ? Every conflict/war raises fuel costs (and never goes back down)... Do you REALLY want to send your cash to OPEC Nations ?
The Organization of the Petroleum Exporting Countries (OPEC) was founded in Baghdad, Iraq, with the signing of an agreement in September 1960 by five countries namely Islamic Republic of Iran, Iraq, Kuwait, Saudi Arabia and Venezuela. They were to become the Founder Members of the Organization.

These countries were later joined by Qatar (1961), Indonesia (1962), Libya (1962), the United Arab Emirates (1967), Algeria (1969), Nigeria (1971), Ecuador (1973), Gabon (1975), Angola (2007), Equatorial Guinea (2017) and Congo (2018).

I would imagine anything more than a couple of those cells it would get out on a pallet.

I would prefer to support American oil but the current resident is doing his best to kill that.

Yea they would be fun to play with for an offgrid setup. EV is noway ready for prime time and probably won't be in my lifetime. Most people don't know anything about oil other than what they read on the interwebs.

I support oil also. I worked on 835ft drillships for many many years as a Chief Electronic Tech / IT. I was also in country for the Gulf War back in my Military days.

And how much does that "Support" cost you over a 12 month period... That is money YOU Tossed into some "Corporate" who gave you nothing in return. Seriously, add up your fuel costs over 12 months IF YOU DARE.
An average American spends between $150 to $200 on gas every month. It, of course, varies and depends on the state, lifestyle, and driving habits. American families spend approximately $5,000 on gas annually, which is almost 2.24% of their monthly income.Jan 11, 2023

IF you didn't know: Look where US stands on Oil...
BUT still totally subject to world pricing that is affected by every situation or event, and decided outside of the US.
Many countries produce crude oil
  • The top five crude oil producers and their percentage shares of world crude oil production in 2022 were:
  • United States14.7%
  • Saudi Arabia13.2%
  • Russia12.7%
  • Canada5.6%
  • Iraq5.5%

I'm not against EVs, I'm against the government pushing them. They make sense for rather narrow corner cases at this point, probably well under 10% of vehicles. They make absolutely no sense for large trucks.

The reason the automakers are pushing EVs so hard is CAFE. It's already higher than almost all ICE vehicles can achieve. They can only make it by the cheating the government let's them do with EVs. First they calculate EV "fuel economy" by using the energy input to the batteries, ignoring that ICE energy input is from the burn energy of the fuel. Since they're ignoring Carnot efficiency they're already giving the EV a 2.5x multiplier. Then they decided that EVs get another 6.67x before calculating CAFE. So the typical EV gets calculated into CAFE at 200+ mpg.

How many $$$$$$$$ have been given to carbon fuel over the past 100 years?

Big Fossil is getting 13 Million Dollars (US) per day globally. The largest & most subsidized industry in the world...
A RECORD 7 Trillion Dollars last year !
REF from IMF (International Monetary Fund) https://www.imf.org/en/Blogs/Articles/2023/08/24/fossil-fuel-subsidies-surged-to-record-7-trillion
Coal, N.Gas, Gasoline, Diesel + breakdowns shown here... Get Ready to be GOBSMACKED ! (look at who are the biggest subsidizes... Russia, China and ...) NOT ANYONES FRIENDS !
www.imf.org

Fossil Fuel Subsidies

Subsidies are intended to protect consumers by keeping prices low, but they come at a high cost. Subsidies have sizable fiscal costs (leading to higher taxes/borrowing or lower spending), promote inefficient allocation of an economy’s resources (hindering growth), encourage pollution...

IF the US ever implements a carbon tax it will also affect the cost of electricity unless that electricity is renewable. Not sure how that pushes EVs. But it does promote producing cleaner, cheaper electricity.

Washington State has a Carbon Tax to raise the cost of fuel.

How would making people use more electricity lower it's cost? That's not how supply and demand works.
 
Those subsidies wouldn't include the US military budget, to keep shipping lanes open and the Middle East destabilized so they don't agree to cut production and boost prices.

https://www.cnet.com/roadshow/news/states-banning-new-gas-powered-cars/

^^^ This is one way EVs are being pushed. I don't believe this will happen but it sure is being pushed.

"Vermont lawmakers approved changes to clean-car requirements that would require new cars sold in the state to be zero-emission vehicles by 2030"

That is less than 6 years from now!!! Vermont is a cold, rural state with lots of mountains. Not the best place for EVs or solar. Residents of Vermont typically drive more miles per year than the average American due to the rural nature of the state.

Any "hybrid" gas engine vehicle qualifies as zero emissions in all these states mandates. That's a huge loophole that will keep gas engines around plenty long enough.

Yeah, States like VT are the worst for EVs
  • Cold weather
  • Long distances
  • High need for pickup trucks
  • Relatively low income
  • Mountains
  • few charging stations
  • suboptimal solar charging

I understood the Washington cap and trade program to apply to any operation that outputs CO2, including power plants? And that they can either pay for carbon credits for emissions above the cap, or they can offset the emissions by planting trees, etc, or buying credits from others.

Renewables are already cheaper than gas and coal for making electricity ... and faster to build too. Can't they also sell off their carbon credits to others?
