Hi @Solarchaser,
Just wondering, if you managed to get the Batteries working?
Regards, CT

Thanks to EVandPV, my us3000 now lives 😁😁

Thanks very much for the links, especially to the lad advising about charging as nimh instead of Li-on.
The charger just showed a fault when I went to run it as li-on, but I charged each pack on the nimh setting. 
My god it took its time.
Batteries all went from 6.5 to 12v in about 10 mind, then about 4 hours each to get to 16v.

It's been a long couple of days, because I was rather concerned about them melting, I had to keep checking them for heat every 10 mins or so.
In truth none of the packs ever showed any signs of heating up at all, but I could only feel the outside, so couldn't tell if the internal was heating up.

When they were all at 16v I left them for a couple of hours and made sure they weren't dropping off.
In theory the wee charger should have then recognised them as li-on batteries,  but it would only recognise 4 out of 5 cells, and so I got a bit bored with it, bearing in mind I spent over 12 hours checking them every 10 mins or less.
So I thought, well 16v across the 3 is 48v, I wonder if the bms will recognise that, and short answer is yeah it did.
So it came on, no charge lights, but flashing run light, so I got one of my 2.4's and used it to bump the charge for about an hour and then I could see the first charge light.
This was about 9pm last night. 
So I thought, meh why not, plugged it into the lux and let the go faster charge it up at 1kw for a couple of hours and stopped it at 85%.
I then let it run the house all night.

So, it works, happy days,  I dont think I have full capacity,  but hopefully that will come back in a couple of cycles. 

Micky does your lux register your 3000 as 70ah? Because mine is reporting it as a 50ah same as the 2.4, and I'm hoping that's a lux reporting error rather than it telling me I've lost a third of the capacity.


So once again, massive thanks to EVandPV, great advice and looks like I have another working battery.

Now my problem is the shelf I made for the 8 batteries, has no room for a 9th.
1st world problems eh 🤷‍♂️😁

Great to hear that!

Damn, looks that I missed all the action in this thread!

SC - well done for getting it back to life - it could well be a good investment. Also, some really good info here, to refer back to, as and when needed.

That charger looks to be a good investment as well.

Anyone know how to fix a faulty BMS ? 😎

Interesting.
I'm wondering, if under the hood, wouldn't most LiFePO4 cells be the same?

There won't be a huge difference between them.
But in this case the cells are fine. It's the BMS that has a problem.

It came up as a seller I'd bought from, because its the ebayer who sells the pylontech communication cables...

I'd like to have a go with that one....

Hi just noticed on my phone App that there is the option to download firmware... looks like I have the option of 5 different versions!

Currently running BAAA-1111

Options are

BAAB-xx04_2021

BAAB-04xx_2021

AAAA-xx19_HinVs..... etc etc

Has anyone done this and if so which version did you install and more importantly did it work

TIA

I asked about this before Mick but nobody said they had tried it.
So I emailed Luxpower in China and they just said BAAA-1111 is the most recent.
The ones starting AAAA- are for parallel inverters, apparently.

i tried it a few weeks ago, downloaded firmware but nothing happened when i pressed flash - connected to lux wifi and still no response when i tried flashing but like i say, that was a few weeks back
