Was having a browse on AliExpress after buying something else and thought I would have a look at lithium batteries, have a look at this.
Lithium batteries are getting cheaper.

If it is a decent battery it could be an indication that prices in Europe may fall or it could be a piece of junk. At that price even if you get caught for duty etc., could be worth a risk.

Personally it would worry me, buying a battery that I wasn't sure what was inside. Might be fine, but might be junk or just plain dangerous. Who knows?
I spent a lot of time recently deciding on a supplier of LiFePO4 for client vans. The one I ended up going with was Roamer - specifically their new, 2nd gen battery.
They have a 10 year UK warranty, a 250a Bluetooth BMS and proper low temperature protection. I spent a long time talking with the company owner who explained all of the upgrades in the new battery and really knew his stuff. I've ordered the new 460Ah version for the build I'm currently doing.

Do they produce the product in the U.K. or is just imported Chinese stock and branded with their company name ?Personally it would worry me, buying a battery that I wasn't sure what was inside. Might be fine, but might be junk or just plain dangerous. Who knows?

It's designed in the UK, then made in China to their spec.
It isn't just a re-branded job, like a lot of others.
It looks the same as others as no doubt is made in the same factories as others, but has upgraded wiring, a more thorough and powerful BMS and the cells are CATL (Tesla supplier).

That's interesting. I'm fairly certain when I looked a couple of months ago the underseat battery was 200Ah. It's now 240Ah. And the price has come down.Personally it would worry me, buying a battery that I wasn't sure what was inside. Might be fine, but might be junk or just plain dangerous. Who knows?

Yeah, these are the 2nd gen batteries.
Hi..... As you mentioned in your post , are you talking about their batteries which are on pre order for Jan delivery ? Have just spoken to them ( guy called Steve ) on their online chat.....He answered promptly ......He also mentioned they hold victron and renogy kit , which is good as I like the look of the renogy dc/dc with built in MPPTPersonally it would worry me, buying a battery that I wasn't sure what was inside.

We’ve tested some of those cells and then returned them. They were way below stated capacity. Who knows how old they actually are - but definitely not Grade A.
Steve from Roamer runs this Facebook group, some interesting information on there.

Expect LiFePO4 cells to fall in price next year. The patents on LiFePO4 cells run out next year.

Because of one of these patents expiring, I already know of a LiFePO4 coming onto the market that will be able to charge at minus 20 (from memory).
It will cost a lot more though.

- I'm a newbie and always will be. You never know it all.
I read quite a lot of your posts and admire your dedication in research of most things technical and advanced technology. I on the other hand am a complete numpty with a very short attention span hence my lack of knowledge.
So my point is what is your considered opinion of the battery in the op's link? My current set up is 2 x 90ah the weight saving alone (given I don't have loads of cash to splash about) would make the viability of 1 x 200ah battery + the weight saving an attractive upgrade.
Agree. I thought these things had a large duty cycle. One year warranty does not display much confidence in the product.
