You have to use paypal or some payment like it to be sure of securing your outlay when things go wrong when dealing with over sea’s i have 2 disputes going on right now and once i have given the seller a chance to make good i will then escalate with paypal who in the past were great at refunding me money back .
But if i lived in the USA i would be buying these up right now

Bruce that looks like a Farmall h being used as the background for your photo. Does it run? Mine needs a complete overhaul and I haven’t even put it on the project list yet. But those are classic tractors I just love the old simple look it has.
The trouble I have here is trying to equate the power and cost between types of batteries.
I am not complaining or arguing in any way, just trying to understand.
One of these is $225+$350 price plus shipping.
$575 for 2.2kwh. This is (according to their graph.) for operating in the 48 volt regime. So I would have to add the cost of a 48v inverter, charge controller, or a buck converter (48vdc to 12vdc).
I just bought 75ah 12vdc AGM batteries for $252 per. They fit everywhere in the scheme of things around here. I can combine them for 24vdc to start the excavator. I can parallel them to work in the 12vdc battery bank. If they are of similar quality as the C&D technologies batteries then I expect a 10 yrs+ life span.
So there are problems trying to equate the two different battery styles. Usage appears to be the main one. The lithium pack appears to be best used in a bank, or perhaps a golf cart power bank. It will require a battery management system. It will require an inverter. It will require a battery charger. It will require a C60 xantrex charge controller or better. Obviously pricing the peripheral components offer too many variables. I would note that there are no 48vdc components laying around used, for cheap. Everything for these batteries would have to be purpose bought or built.
The only thing I can say about the 12v batteries is the peripherals are oftentimes free, or can be had very inexpensively.
So what about the math…does it offer a fair comparison? Even this is tough. The graph shows a voltage drop to 56.10vdc after ~1hr. It shows it delivering 9 amps. So I get ~505watt•hrs for the first hour. The AGM should be cycled no deeper then 20%. So 15amps for an hour•12vdc• 4batts gives 720watt•hrs.
$575/505watt•hrs gives $1.14/watt•hr
While AGM
$1008/720watt•hrs gives $1.40watt•hr
If you made it this far…I don’t know what your conclusions would be… There are other comparisons that don’t match up either. AGMs don’t explode if your charge controller screws up. So less danger.
AGMs seem to take a charge in the cold. I have difficulty charging the lithium batteries in the cold. On the other hand lithium will give up it’s charge in the cold, while the bottom drops out of cold AGM really fast.
My conclusion is there is no fair way of comparing the two battery types. An analogy would be trying to compare my dodge caravan and my artic cat Puma. They both go on the road, they both go 70mph, they both get 20mpg, but they both are vastly different.
Dan, thanks for asking. It did run. I stole the rod bearings out of it to bring the oil pressure up in the other one my son uses. I used to run the Belsaw mill with this. It has F12 rims which I think are really cool. This tractor was brazed back up after the ears broke off the drive shaft tunnel. I am stripping another tractor to get it’s tunnel for use with this tractor. Eventually, this fella will be running on charcoal. There lots of things to do first tho. I would like to find a magneto for it. We also have to get a throttle block made to replace the carburetor.
I like the H. Very easy to fix. Very easy to fuel with gas. Lots of tools that run on the belt or rear PTO. 5 to 1 compression ratio or less, so they can be cranked on gas by hand.

The mag is available but for the money I think I would switch it over to a distributor from a newer number serries then add an electric ignition setting the tractor up as 12 volts positive ground. It all depends on how much of a purest vs function type of guy you are. But for me it would be worth the upgrade. I priced that as part of rebuilding my H because I know a broken coil in the low speed circuit is why my H has never started since probably the 60s. My grandfather bought it new in 50 and always said you pull it because it won’t start and a new mag will only fix it for a short while. We always pulled it when I was a kid then in the early 90s the engine was just too worn out and wouldn’t make any power. It would need a full engine kit plus a full rebuild
Maybe some day when I have money to spend on a peoject.
hour of digging , paid $1.13 in per watt in march 2013 . 28 eoplly 109 watt panels . Paid $300 to rent truck to pick them up . have 42 mega watt hours from inverter .

Dan,
Sounds like your mag needs that spring so it snaps at low speed. I had a spring break on my t-9 and then we had spin it fast inorder for it to work. I did switch that thing over to a distributor. Same mag as an H. Infact the distributor I used was out of an H.
Mags don’t need batteries. This build is my version of the Mad Max doomsday car (only it’s a tractor).
The hilarious thing about Hs is every time I go to purchase a rebuild kit, some one offers me a running H for less then the price of the kit.
No I am not a purist, hence the F12 rims.
Computer advancable electronic ignition might be fun, but an H only is supposed to spin up to a 1000rpm, and a 5 to 1 compression ratio or less means those piston speeds are pretty slow. Plenty of time for a carbon monoxide flame front to develop and start pushing.

Henry, that sounds like an incredible deal. I bet there will be more of these in the coming years…how far we’ve come hey?
This stupid thing was the pinnacle of what I knew and could afford in 1991…

Good idea with the tire under the genny.

That is my “whole house” generator also bought in early 90’s. It has only been used for power outages and is still like new. I also run mine on a tire to keep it from running away.

We just started solar cycle 25. As it ramps up, there will be increasing blackouts. Homeland Security says to be prepared to go up to 6 months without power. They are talking about EMPs. The real danger is the CMEs. We were recently just missed by a X-10—X15 flare. There will be a LOT more. I have 16 acres in western Oregon that I am developing / prepping.
I found a couple of DC generators off old arrowboards. One was Lister powered. The other was Yanmar powered. I switched the alternators to 24 vdc. My complications had complications:)
I bought twenty five 200 watt panels. I bought two Midnight solar controllers. One died, one just didn’t work. Still have to work out that whole situation.
I’m in California and, my guy in Oregon is building / maintaining everything. I bought another Midnight Solar controller. I also bought a diesel 28 vdc generator, military surplus with 4 hours of run time.
It is yanmar powered so, I expect to refuel it after a couple of weeks of run time.
I recall that I paid about $600. The other Yanmar & Lister machines will need some work.
I’ve been prepping for some time now. I run across deals.
I have a 15 kw Kohler propane
Three 7kw Kohler RV generators
One 5 kw Kohler
One 7kw welder /generator
One 3.5 kw welder generator
I ended up buying 105 batteries. 16 of them.
I really don’t have much in the way of loads right now.
Yes, the debt collapse is coming. Don’t rush it. You need all the time you can get.

Ok on the solar cycle. I am looking forward to 11m skip again. 10 meters will work again too.
CMEs always bring the beautiful auroras too.
I have two of those Yanmars that I brought home from Iraq. I have had them generating DC power for 15 years. They can be started by hand with a squirt of WD-40 in their primer holes as low as -30F.
Ok on the 105s. I still have two junkers that have to turn in for cores. They need tender lovin’.
Wow! Good deal on the panels. Sounds like you might want to check out Schneider Electric. They sell a charge controller, 4500 watt that handles 600volts. I ran #8 wire 300 feet feeding those charge controllers 190vdc.
OMG, I do ramble.
You have some good gear. I hope you can deploy it before it’s very hard to do.
My mouth is watering just thinking about all your goodies you certainly out do me on the generator collecting front that’s for sure .
I have just upgraded to Vitron solar controllers they can handle high input voltage i think and come with a 5 year warranty and are Bluetooth and lifepo4 compatible .

No one who saw the flare of 1859 is still with us . We have all experienced disruption of some kind
The Carrington Event[1] was a powerful geomagnetic storm on September 1–2, 1859, during solar cycle 10 (1855–1867). A solar coronal mass ejection (CME) hit Earth’s magnetosphere and induced the largest geomagnetic storm on record. The associated “white light flare” in the solar photosphere was observed and recorded by British astronomers Richard Carrington and Richard Hodgson. The storm caused strong auroral displays and wrought havoc with telegraph systems. The now-standard unique IAU identifier for this flare is SOL1859-09-01.
A solar storm of this magnitude occurring today would cause widespread electrical disruptions, blackouts and damage due to extended outages of the electrical grid.[2][3] The solar storm of 2012 was of similar magnitude, but it passed Earth’s orbit without striking the planet, missing by nine days.[4]
patented the Humphrey pump in 1906.
A similar pump, the Joy pump, was also described at around the same time. This was much smaller, around six inches in diameter rather than six feet, and also had much smaller water pipe connections to it. This reduced water mass also reduced the compression ratio available in the combustion chamber, leading to reduced efficiency. The pump’s ability to work with a suction lift of a few feet, rather than needing to be submerged like the Humphrey pump, was a convenience though. This pump was thought to have some application for small-scale or portable tasks, where its convenience outweighed efficiency.
Polypump sold patent to Pittway , Seaquist valve company .
Was this pump more then a drawing , Was it ever built ? Was It ever sold ?
There’s just a few manufacturers that make every lead acid in the world. For some reason I want to say less than 10.

Here is an amusing antedote for any off grid people. The set up…when one runs generators, it’s wise to plug in all the battery chargers and build bank voltage back up while busy with generator tasks. When one runs off the bank, and solar, it’s a good idea to unplug all the battery chargers. When one is between good inverters with automatic transfer switches…this battery charging is accomplished manually, by plugging in chargers, or unplugging them. If during the transition from generator to inverter, the battery chargers are accidentally left plugged in, they draw power from the inverters and charge the batteries feeding the inverters. If one only monitors voltage, this has the APPEARANCE of perpetual motion.
The camp we live in is a single wide mobile home, that if one squints a bit, is reminiscent of living in a submarine, or (after watching The Expanse too many times) Skylab.
This afternoon, after a beautiful sunny day, storm clouds rolled over the panels and bank voltage dropped enough to stall the saw I was using. I made my way to the engine room and started the generator.
The crew heard my order bellowed from the engine room, “All hands, engage the perpetual motion machines!”
I could hear laughing on the crew deck as the bank voltage shot up to 12.3v.
Seems like everyone has adjusted to this alternate reality.

There aren’t very many. However even if they are made at the same factory, it does not mean they have the same components.

That is so true and so impossible to convince some people of. Having worked at factories that used the same production line for different products I am always amazed when people don’t understand how much you can change the product by changing the raw materials on the same line. The headlight factory I worked at made something like 6 different products on the same line and they where very different products.
It is one of those myths that seems hard to shake people of that the same line can make very different end products.
