Has anyone seen these batteries? Any views on them 200ah for £649 !

<Broken link removed>
 
I very recently looked at these because of the price but you will have to take into consideration the delivery timescale. I think it was either 3 or 6 months for that price.

I just bought 200 ah for 649 from amazon. I did some research and amd as content as content can be that they are all right. Delivery time this week

I suspect, but dont know, someone has imported a load from USA or Canada. Currently 5 left. I cannot reccommend them but I can say cheapest I found that wasnt with a long delivery time

Amazon product ASIN B0B612H28W
 
It’s not clear from the website whether the BMS parameters can be edited/changed.

Its says tesla cells, hmm wonder if they re NOT made in China? If so I'm in.

I am not familiar with them. But if they say Tesla cells then they are made from 2nd hand cells. Tesla do not sell their cells to 3rd parties, they use them all in house.

I was in contact with this seller few weeks ago. The reason, he had 24v at a good price. I actually got a offfer under the asking price. My interest dropped when I asked about the cells, as in one spec says Tesla cells and on another spec mentioned prismatic. Tesla are cylindrical second hand, and prismatic probably b grade that did not pass certain tests for A grade. I dropped out since roamer can do good deals on big buy with preorder paid in advance.

Ok so maybe not the best.

The only downside appears to be perhaps being made in China; the article above seemed to suggest that unless you want an initial quick delivery of energy such as formula e cars the cylidrical cells are the way to go. But the prismatics will soon be in the majority and for slow drain usage as in a motorhome house battery they seem perfect.

Aren’t most things made in China ? I don’t think we can be precious about China and it’s issues when so much in most peoples lives is made in China, I have just bought some bits and pieces for my van and there was no alternative but Chinese manufacture.

The main point I was making was in relation to the 'bringer of bad news' post by funflair in relation to prismatic cells in a Lithium Battery; which was not borne out by the article he posted when used as a leisure battery.

Ah OK

I know that Jon has an aversion to anything that comes from China and is waiting for a non Chinese LiFePO4 battery, this won’t be the one though 😏

And yes there doesn’t seem to be much wrong with Prismatic vs cylindrical, I know Super-B use then in their “drop in” Epsilon battery.

Victron ? Designed in the Netherlands but built in China?

Thats my point, China has got way too much control, we are allowing an un-accountable, one party state with values completely incompatible with ours to become sole supplier in too many areas. Ultimately we will get caught with our pants down like the Germans have been with Russian Gas.

Those who fail to learn from history are doomed to repeat it.

I agree with what you are saying to a degree, but until there is an alternative source of manufactured products we will struggle to boycott Chinese products.
Are you going to do without if you cannot find non chinese products?
 
The IP on lithium-iron phosphate batteries has until recently been owned by China. It's tech they developed. The licences have recently expired. But most of the expertise is still there. If you want an LiFePO4 battery, it's very likely the cells are from China.

In terms of prismatic vs cylindrical cells. A leisure battery isn't going through continuous high current charging and discharging cycles that'll cause overheating issues, so the surface cooling benefits of cylindrical cells aren't required. And Prismatic is more compact and has less connections to go wrong. I think prismatic is a better solution for leisure batteries.

There are some things you can't avoid buying Chinese but I always look for an alternative and even though it invariably means paying more I will usually go for that one.

I realise its no longer viable for us to make cheaper items- ironically because we ( and most of the west) have tried to build an environment where people aren't paid pitiful wages and treated like crap. Them making kids toys and the rubbish in the Bazaars isnt so much of a problem but when they re making most of our communication devices and other essentials then I think we should be encouraging other countries to make it so we at least spread our risk. Try buying a light bulb that isnt made in China.

It's the logic of free trade and if there were no import duties would be way worse we would probably lose the remainder of our manufacturing pretty fast. It's conveniently forgotten by people involved in making money on imports.

Hi Steve and Denise which did you buy? I’m thinking of buying the 420Ah x 2 and your feedback has helped 👍
Click to expand...
I only bought 1 x 300ah but now realised I could have got the 460 ah in the same place, but 300 ah is probably enough as we have never run short as yet backed with 350w of solar and Denise uses as much as she wants ie kettle microwave tv and compressor cool box. If I was doing it again yes 460ah and another 175w of solar but would be a bit over the top for our use.

Sorry to be the bearer of bad news Jon but these are prismatic cells and make in China I believe ;)

Does it matter if these are made in China or not many goods we buy even the good quality kit is.
 
Anyone who thinks that its too difficult should have a google of 'Debt Book Diplomacy', this is how China will ultimately overtake the US, its clever and subtle but its already working especially in Sri Lanka

It's a bit like a friend of ours refuses to buy anything French since they "made up" stories of side effects with the az vaccination because they're anti British. The fact it later turned out to be true never seemed to make any difference!.

Its not exactly free trade with China. Because all businesses are in effect controlled by the state they can afford massive subsidies in areas that they consider important and keep them going until the alternatives have to give up and then as sole supplier they can charge what they like. The Steel saga was an example of this. Likewise our manufacturers are between a rock and a hard place, if they don't let China make their goods, the chinese will just copy them and sell something pretty similar at a fraction of the price. The west are sleepwalking into this.
