100ah 12V LiPo battery (with BMS) for £349

Their complete solar kits look great value as well.
 
The peak discharge current is 100A so wouldn't cope with a bigger inverter. Also no mention if the BMS has a cut off to prevent charging below freezing which will damage a lithium battery. They don't have Bluetooth so monitoring will have to be by an external shunt which will cost about £100-150.
But certainly a good price.
Guarantee?

One of the reviews suggests that there isn’t low temperature charge protection.

little by way of reviews of company or products.

They may be genuine of course.
 
Interesting cell configuration... 4S10P Wonder why they went down that route and what the cell packaging is?

Am I missing something or are these the cheapest LiPo now? Seem to be half price of other brands? I have ordered and used EcoWorthy panels and they have been good quality.

Like you, I have used EcoWorthy Solar Panels and found them good value and reliable.
I doubt they make the Battery, but buy in it from one of the Chinese factories and I would expect it to be decent product.
However, while it is also a decent price indeed, it is not half - or even close to half - the price of rivals. For twice that price, I would expect - and would get - a Lithium battery with a higher current BMS, bluetooth capable and with built-in pre-heater.

I have ordered solar panels from them, 3 years ago and 12 months ago. Good service 👍. But yes, no UK office that I know of.

Certainly already fallen a bit/more offers around but there are also still upward pressure on commodities so could equally start increasing again.

the continued fall in price has been tempered somewhat by the CCP putting on a "safety surcharge" on shipments of dangerous goods such as Lithium and a number of factory fires in China hitting supplies

Says 5 years so depending on small print, reasonable against KS at 7 and Roamer at 10 for considerably more

No UK base they just drop ship in the UK & any warranty is only as good as the company if they dissappear warranty disappears to.

Yup. Risk of not honouring a warranty irrespective is always a concern. I was pretty disgusted with Fiat/Autotrail when they refused to accept a fraying seat belt as a warranty claim after just 9 months of ownership from new. Wear and tear they said!

Sometimes need to insist. the little plastic clip that acts as a "belt tidy" broke on my car shortly after I bought it. The Dealer said it was not covered, but I pointed out it was made wrong (the belt looped over the thin plastic bit and NOT the metal part (so totally useless in an accident!) and if they preferred to speak to Trading Standards instead of me? New Belt fitted FOC ...
I think a fraying belt is equally a safety issue (the belts on my Fiat/Autotrail show no sign of fraying after 14 years and >100,000 miles).

Yup. I played the safety card but not interested. It was either caused by rubbing on the sharp edges of the plastic as it came through the cab lining or on the spool itself. They originally blamed mice!
A quote to fix it was between £400 and £650. I took it all apart in something like 15minutes and got http://www.fdts-seatbelts.co.uk/ to fit new webbing to the reel for about £30 and refitted myself in another 15mins.

LiFePO4 cells should start falling this year. BUT demand for them is huge probably a lot larger than supply. So don't expect them to fall too fast.
China has only just lost the patent protection so it may take some time for other companies to start or ramp up production.

Just got an email with notification of a Renogy sale which might be of interest

I didn't know if it was a oem or dealer sale.
