Hi @koeniglicher -
I own 4 of the 8s4p batteries, from a MachE, I started backward engineering the pin outs, I now know enough pins to make it useful, but not enough to figure out what the manufacturer of the connector is.
I tried to go to ford, to buy some cabling, but they wanted a VIN, which I do not have.
I just need a stationary application.
I used breadboard to header pin wire extenders to connect to the 2x sockets on each battery, but those wires are very thin. I may be stuck with them. 👎
Maybe I can take some more photos, zoom in more, and take your suggestion…

@royh6526 - “how about less dirty”
Heavy metals buried in the ground mitigated by energy expensive industrial systems to try to isolate the heavy metals from batteries & solar panels???
Compared to burning natural gas or butane hydrocarbons, held in a steel tank which is 100% recyclable, which consumption produces plant food that is naturally recycled?
I definitely prefer the less dirty solution.
I am not against batteries, we need batteries for very portable solutions, like cell phones, laptops.
Liquid fuels store much more energy than batteries, which is why people use butane powered soldering irons and gas powered welding torches (and not battery powered irons & torches.)
The right energy source should be used for the right job, so as to best use our energy resources efficiency.
Carbon has the ability to form 4 covalent bonds, meaning living things can create & break down sugars as fuel, in an indefinitely recyclable process.
Indefinite recyclability is clean, this should be the goal of humanity. Anything else produces waste and to some degree becomes morally wrong.

Dave - “basically a factory”
@Stefan_Dahn - “NOT a factory, just offices”
Power tools, air compressors, warehouse level high raised ceilings, moving vehicles around, tearing vehicles apart in the facility, etc.
So, maybe not a factory, definitely not offices. Something in between? I think so.
“ALL IN for renewables”
If so, a second natural gas pipeline would not have been getting built from Russia.
“gas storage full faster than planned”
If renewables was 100% functional,
Germany would not need gas storage.
Renewables are needed, we should increase usage, but we must introduce renewables where each source is capable of delivering base power when their windmill is not spinning or the sunlight is not shining.
There are many solutions, they need to be implemented, with every installation.

@NdxtremePro - today, the brine is underground, has lithium in it with other metals & minerals, the brine is pumped out, brine spread over large land areas to evaporate the water, then the salts are harvested for lithium extraction.
The water 💧, unbelievable amounts of water 💦, is evaporated as a waste product.
The reality is, the water 💧 is a precious commodity that should be captured & reinjected into the ground, to keep the caverns from collapsing. As the caverns collapse, the harvesting of lithium will deteriorate… more likely, they will take fresh water 💦 for human & agricultural consumption & inject it into the ground, to sustain the mining in the future.
Lithium mining is so bad, on so many levels. It is like watching a train 🚂 wreck in slow motion. We know what is going to happen, as we see the symptoms already.

@jamesengland7461 - - “Bolt sales were terrible…”
Not many were produced, because there were not enough batteries 🪫
“Before the supply chain broke”
This has nothing to do with the manufacturing of EV batteries 🪫- which was practically non-existent in the US and other continents outside of Asia. That is changing, now.
“Cars like Coronas and Civics have been profitable for a half century…”
They have traditionally cost more than typical American compacts.
Their primary markets were foreign, with small car 🚘 needs, which became US domestic. Ironically, the civic will be withdrawn from the Japanese market.
But none of those [un]/profitable small cars had to sport a huge & expensive battery 🪫, where the supply was low, and the battery 🪫 cost more than the car to produce.
“GM has always done poorly with small cars”
GM built lots of sporty Pontiac Sunfires, nice affordable Chevy Cavaliers… enough cars 🚙 were built to meet various standards: an aggregate of the cars sold by a manufacturer had to meet x MPG, so the incentive was to sell profitable vehicles while the smaller vehicles were an afterthought & often produced in quantities to meet their US fleet MPG requirements and keep their costs down by sharing parts with international market cars (which demand smaller vehicles, while US demands larger vehicles.).
“always been profitable”
Rick Wagoner, former CEO of GM, former president of GM’s North America Operations said it was tough to make a “net, net, net profit on small cars anyway.”
For every Ford Escort sold, when it was the #1 selling car in America, Ford lost money 💴 on every car. Moving manufacturing to Mexico helped bring down costs.
The luxury brands of the American Cars 🚗 always subsidized the starting cars for the poor… until recently. The #WarOnThePoor has taken it’s effect with car companies being less concerned, especially since used cars were crushed a couple administrations ago.

@Dirt-Diggler - “a normal generator would be cheaper to run?”
Depends on the vehicle.
For your van, maybe not.
For a subcompact? Hybrid which turns itself on/off? Plug-in hybrid? (Plug-in hybrid is the perfect use case for such a system.)
Also, many benefits, may not apply universally:
- generator is very loud, ICE car is quiet
- generator & ICE car both need maintenance (better to maintain & test just one ICE, ICE car is likely to get more use/maintenance than a generator)
- in an emergency, an ICE car may have better maintenance previously executed than a generator (filters, oil, gasoline, etc.)
- Large generator less efficient than sub-compact ICE car engine (sure, smaller & more expensive generators may improve efficiency, larger ICE may be less efficient & more expensive.)
- large generators have more emissions than sub-compact ICE car (a lot of effort goes into emissions on ICE cars.)
- ICE components of generator are redundant to car
- generator requires constant refueling (x hours), while car ICE tank is huge (x days)
- larger generator requires separate storage or hauling around, vs ICE car which already has storage area & likely with you when you need it
- separate generators with fuel are likely heavier than inverters for a ICE car, making handling easier for older people
- generator fuel requires changing or stabilizer once too old, ICE car fuel is more likely regularly used and does not run into this problem
- 3000w generator ~$600-$900 US$ without external Bluetooth performance metrics to phone vs cost of a 3000w / 6000w peak inverter for a car is less than $300 US$, with Bluetooth performance metrics to phone… full sine wave inverter is a little more
The benefits of having an inverter with your ICE car means all kinds of things can be safely run, without having a pickup truck for the generator or a trailer hauling around a generator, not to mention canisters of gasoline… like using sound equipment at a site, run a bounce house, outdoor lighting while at a camp site, projectors for camp songs with youth (try singing over a generator), refrigerators for medications while camping for younger & older people in remote areas, running popcorn makers for groups during outdoor camping events is a bonus!!! … the benefit of running your house, or an elderly friend’s home who is having an outage when they have serious needs like oxygen generators, in a pinch, is always a nice benefit!
“Alternator”
Yes, my car has a big alternator, I can run half my house, but it can not run my whole house Air Conditioning compressor load.
If it is something I would need to do often, I would add a separate parallel 12v battery, sit that battery next to my inverter, with a trickle charger on it… so I could just add my ICE car to it whenever needed (ie US East Coast during hurricane season.)
“Van… efficient”
For a larger vehicle, the efficiency may not be a great deal… but for once a year events, I think it may be worth it for some people, even with larger vehicles.
“Small car if you can’t fit the inverter inside”
Can’t fit under front hood. Can fit in rear trunk.
Depends on how much power you need to pull… to run my whole house heat & whole house fan, with 2 full refrigerators/freezers, I need a lot of power… and I like to go to sleep at night during a power outage. There is not enough room under the hood of my car, which would be close to the battery & alternator.
I would need to have significant 2 AWG cable from my battery to my trunk & the inverter makes some heat when under load… if I need to leave the car idling for days, the trunk should be closed, to avoid impacts from condensation or rain. I prefer to have airflow around the inverter for long uses, so long term use in the rear trunk is not a great idea.
“Better to run A/C on a longer lead than D/C”
It is cheaper & parts more accessible for me, to use 6’ 2 AWG cables from battery to the garage vs 12’ cables from the battery to the trunk… the A/C lead, as you said, is better & extends nicely!
