EOI - New Yinlong LTO cells Australia

Post by BaronVonChickenPants » Sat, 09 Mar 2019, 11:28

I have been approached to distribute new Yinglong LTO cells in Australia.

Apparently Yinlong were having some internal troubles last year, to continue trading they were dismantling pre-assambled battery packs and selling these cells cheaply, these are the cells most of us have been playing with.

Now they have overcome their issues and are back in full swing producing and supplying new cells.

I have been offered access to Yinlong's full range of new A grade LTO 2.3v cells: Cylindrical 66160 30Ah,35Ah,40Ah ,66260 55Ah and prismatic 30Ah and 33Ah.

Still early days and I need to work out exchange rate, order quantity, freight costs, etc but pricing for cylindrical cells should come in under AUD$3/AH for cells in Australia.

Cells would be provided with a tax invoice and warranty.

We can provide freight Australia wide.

I am looking to predominantly order 66160 40AH cells but open to requests.

If you are interested can you please indicate the cell type and quantity.

PS: Sorry if this post is in the wrong place.

We have finalised cell pricing on cylindrical cells.

Our goal is to match, as best we can, Aliexpress pricing landed with GST for A-Grade Yinlong cells, yet provide local distribution and support in Australia. As the cells will be locally stocked and distributed there will be no customs and import fees or issues for buyers within Australia. To only additional expense will be local freight within Australia.

As long as the exchange rate does not change dramatically pricing is as follows, this is based on $2.12/AH:
66160 30AH AUD$63.60 each inc GST
66160 40AH AUD$84.80 each inc GST
66260 55AH AUD$116.60 each inc GST

Size:
66160 and 66260 are big cell formats:
Both are 66mm diameter
66160 are 160mm long + 2 x 25mm terminal posts = 210mm and weigh ~1.15kg
66260 are 260mm long + 2 x 25mm terminal posts = 310mm and weigh ~1.9kg

Do you have some spec sheets in the cells?

Advantage of Lithium Titanate Battery:
1. faster charging: 6mins fully charged
2. high discharge rate: as much as 10C-15C
3. wide working temperature range: -50°C ~ 65°C
4. super long cycle life: over 30,000 times

22kVA 3-phase at home charged in 6 min is 2.2kWh.
So an electric scooter with 3 phase charging?!?
Bigger than that you either need DC charging, your own sub station or will be slow charging just like every other chemistry.

Well that's not really any different to Similar costing LiFe or NCM.

Great...
If you live in the snow mountains for that 1 in 50 year event.
Or planning to drive to Antarctica. :arrow:

Over a typical 10 year life that's 8 charge/discharge cycles per day.
Or nearly an hour per day charging your 3 phase scooter :lol:

The only 2 markets I see for LTO is things that need high power eg Motorbike/ racing but it's more likely that other really high C LTO's would be better suited for this application.
The other is something that does short runs and has the opportunity to recharge multiple times a day such as courier, circle route bus, postie etc.
And you would either need to tender or get in on the design phase of those to sell.

For a regular electric car conversion I don't really see the benefit of LTO over other chemistries.
To make it worse they are heavier / less energy dense.

Don't get me wrong I'm sure they are great and good on you for wanting to make a path for people to buy them.
But I see it as a very limited market.

Have you planned on where you're selling these to make it work?

I think they would be excellent as a replacement battery pack for the series 2 Prius to extend the all electric and greatly extend the mixed mode range. The issue with LiFe cells is the high charge rate the regen pumps out, often seen as high as 180 amps on the scan gauge. That is a 4.5CA charge rate for a 40Ah cell and the LiFeP04 chemistry won't handle that sort of punishment. Even the 120 amp current transfer into the NiMH traction pack (3CA) makes the lithium cells vent a bit so a fan is needed to vent the smell outside.
I'd want to test a few cells first, but if they meet the claims I'm interested.

Mean and nasty people :lol: Still love both my series 2 Priuses or Pri or what every the term is these days. If I can modify them to tow behind a motorhome I reckon I could develop a great market for bringing more of them back from the dead.
There is a member of the SA chapter that is developing the motor/generator into a 2 stage drive motor with the output being via the input shaft and the whole diff assembly removed and the driveshaft holes blanked off.
If he gets this idea up and running it opens up a whole new repurpose of such a cheap to buy motor/gen set.
