Hi guys,
Yeah, it's going to be about $700 as a single shipment, give or take. You can use my Northline account if you want.

For Kurt and Chris.

I would like to go ahead and get these cells and use Chris's account for transport.

If they are still available:

Kurt, how can I pay you? Chris, how can I pay you?

Kurt, can you liaise with Chris and get them to me please? I feel I am too far away to be effective for this exercise.

Delivery to:
Jeff Johnson
Any freight depot in Emerald, Queensland.

My phone 0447 114 496
jeffj@jeffswalk.com

Thanks,

Jeff

Sorry, I've been a bit slow checking this thread, I've agreed to sell them to Ivan in Perth. Jeff, I will let you know if that doesn't work out.

Ok Mike. It was a bit out of the box to try to get them from so far away.

Thanks Chris. I sold the first lot of 8 as two sets of 12V to tech savvy friends for off grid systems. I am in regular touch with both and they are very happy. I provided the Deligreen balancer with the batteries. So far, they love them and happy to get lithium at such a good price.

Does anybody know is someone is selling any 460Ah AVASS cells. A mate and I brought 16 of the first batch of 460Ah AVASS cells. 8 cells each. I am using my 8 cells for my 24V off grid system. Now in the early morning at about 58% Soc, while the rest of the cells remain around 3.2V, 2 of the cells drop to 2.9V and 2.7V and the lowest one drops to 2.56V. When a load (e.g. a kettle) comes on with a cell at 2.56V the voltage drops below Vmin and operates the LV relay. I would like to replace these 3 cells. Ideally I would not only like to replace these 3 but also have a couple of spares in case anymore also start to play up. Does anyone want to sell some or know someone who is selling some? Cheers

Sorry, do not know anyone wanting to sell.
However, I bought 8 cells (no spares) and fortunately they are going okay so far. I can get about 430AH from them in a 24V system at rated current 0.2C.
One of the cells is definitely weaker than the others, but at the price the 30AH or so is no big deal.
I presume you have a decent BMS and your cells are being well top balanced?
You have probably already checked, but if the cells are badly balanced you could have that behaviour.
My apologies if you have already checked everything and your two cells are indeed only capable of around 230AH.
I certainly hope not to encounter such an issue in the future! It would be a real bummer.
Cheers,
Dave

Hi Russell,

I might be moving on my 460ah 48v battery. Let me know if you are interested.

I just found an Alibaba supplier of these cells:

Might be a good source for more spares.

Thanks Chris. I have been worried about what I would do if a cell died.

Very good discovery indeed! Well spotted!

Great there is a potential source of spares and/or additional cells.

I find it interesting that they rate them as 400AH whereas ours are supposed to be 460.

I've been running my 8 for months now and consistently get almost exactly 400AH out of them.

Price is also exceptionally good although freight might dent that a bit.

Best Regds,
Dave

So who is the original manufacturer of these cells? The alibaba seller isn't.

To those people who have successfully completed their AVASS battery installation, I have some questions about your battery interconnection links.

I plan to strap my cells into 4 rows each of 4 cells then connect these cells into a compact 4x4 grouping, this will require links of 2 different lengths.

Did any one purchase flexible laminated copper battery links, if so what sizes / dimensions and which supplier do you recommend?

For those that have manufactured custom links from rigid conductors, what materials and cross section dimensions do you recommend?

For rigid links, I expect terminal holes should probably be one hole and one slotted hole for best alignment and least stress on the battery terminals.

Does any one have photos of their completed project to post here? I would be pleased to view them.

Cheers, Steve

Hi Steve,
I used the ones of two different lengths that came with the second batch. They are platted copper and they are laminated.
I also used conductive paste for the holes and the contact surfaces.
The holes are close to the right size (slightly over, which is good) and because the plates are curved and flexible, you can get the cells snugly together.
Not sure I have any photos.
Max I have pulled though is 220amps. I love a few mV per strap and two bolts.
I found SS bolts lost me more and heated up about 25deg so I used threaded brass rod with pure copper washers.
Regds,
Dave

PS- I used 75sqmm cable and kept them short- all my cables are about 40cm long. They get warm at 220A but pretty cool and low loss at 120A which is my more normal draw.
