Nothing wrong with Lipo just got to know what you are doing. Easy to learn. Lipo cells can last just as long as LifePo4 its all about how you cycle them. If you never cycle them they can last a long time. For what you can get them for you can build a huge bank for less than LifePo4 new and if you build it right they will last just as long. If you build large enough to where you are recharging before dropping bellow the nominal voltage you are not really cycling the cells.
These pack cells are safer that most other lipo’s as well as they bloat out if they fail so they wont short and catch fire. But still should be use with caution. I will eventually build this much larger in an outside heated unit.
Yeah deals like that are what you want to look for dont buy new there are plenty deals out there used and they are generally fully tested and are beyond 80% capacity. Just use reputable re sellers like Battery Hook Up and others. But you should also test them your self and order extra in case you find bad ones. It is worth your efforts to build your own system.
How trustworthy is Alibaba especially with out current political issues with China? I ordered a washing machine control board from a Chinese Website last year. Half the price and very elaborate looking site. Money down the tubes. No product, no way to contact. No recourse. Then had to worry that they had our debit card info for months. Later found out that there are a lot of these scam sites.
Alibaba is more like ebay and has a payment system like PayPal so you have some protection. I have used it for some small things under $100 total over maybe 5 orders with no trouble. That said make sure you know the delivery and import rules for any batteries you order they can require some special consideration with shipping I forgot which ones are considered explosive. But there was one technology I looked at that a friend of mine who is a retired trucker informed me I couldn’t transport across state lines with an operator licence because of the risk involved with the volume I was looking at for off grid.
The thing with China is fraud is a massive issue if you are cought the penalty is crazy so alibaba tends to be very safe from what i have read.
You can be caught. . . .be had on any Internet non-manufacturers purchase.
I am still hurting $1100.+ usd on a used ESAB TIG welder I E-bay won on.
72 pounds and the shop owed it boxed it and shipped it UPS. That unit got from waist high dropped many, many times. The three layer corrugated box when received looked like a well used brown medicine ball.
Sign and receive something? Refuse? And send back, and try and get a Pay-Pal refund?
I signed. The metals housing corners were all crushed rounded. One of the internal transformer magnet cores were shattered. NFG. Powers up. No welding arc.
UPS claim? “Improperly boxed by the shipper”. Pay-Pal E-Bay claim? Go thru UPS. Record a satisfaction rating.
I did later not bid; but E-Bay Buy-Now, on five deferent BIG permanent magnet used motor-generators. Redi-LIne’s. 2 1600 watters. 3 800 watters. SPECIFIED to the seller(S) just how to multi-layer corrugated box these up WITH side cut in hand lifting pockets. Offered them a person-to-person $50 cash bonus if boxed shipped USPS the way I’d specified. AND received not shipping damaged the way, and recieved just as they had pictured them. 4 out of 5 did get their $50 bonus’s mailed to them. The fifth one, a cabinet shop person, had to get cute and make up a sawn board coffin box to ship it in. Received that USPS filament shipping tape overstraped to hold the four with grain split box pieces together. And with the motor-generator damage!
I just bought a new production vehicle system scanner from an auto parts store. for retail price. Amazon? I checked the reviews. All brands had many one-star 5-13% negative reviews with those complaining that they bought new, did not receive new, but re-boxed returns. Some they could not even register with the manufactures for warrantee and updates. Used. Already registered with the first buyers.
Pay more; to get more.
Just be sure you do get more.
Face to face can insure this.
My big heavy Trace inverter I E-bay bid bought I drove 350 miles to person-to-person pick up.
S.U.
This was $79 delivered from AliExpress. 100watt monocrystalline. I have received 9 of these that were made in Canada, and this one was made in China.
Two were received broken. One was replaced by the company in two days. The other was scratched and they gave me a credit for my next one.
Overall, I am extremely pleased.
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 https://batteryhookup.com/products/lg-14s-48v-2-2kwh-lithium-ion-module?rfsn=1727885.2bd9ce
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.
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.
10/31 Zoom is now worth more than Exxon, I have ten questions – Mish
This tells you all that you need to know about financial engineering.
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.
