E63 LG 63Ah NCM battery group buy

[francisco.shi]

I am going to buy the cells for my battery pack and I was wondering if anyone would be interested in getting some of these cells.
I will need to buy 200 for my self. I am hoping to get a total of 500 cells or more to get a good price on the freight.
The cells are US$45 per cell which works out to about US$190/kwh.
I can also supply the clamps for the tabs, BMS and the mounting hardware for the cooling system but I don't have a cost for that yet.
If anyone is interested could you let me know how many would you buy.

Mmmmm....
If I've done my sums right, a 150V 37kWh pack would cost about $10k (AUD). It would weigh about 160kg without the mounting hardware. That's 166 cells. I'd decrease the weight of my vehicle and increase the range to about 150km.
I might be in the market for a new battery soon, and this is very tempting, but I probably shouldn't. Too many other projects on the go...

That is an outstandingly good price - better than the cheapest 18650 cells and less trouble to assemble.
Alas I am in the same boat as Christopher - need to finish other projects before I can get onto new ones.

The weight including mounting hardware and cooling system is about 200wh/kg all up as a pack the only thing you need is a bracket on each end of the pack and something to cover it so you can't touch the live wires.

Your sums are right. The 37kwh pack would weigh 185kg.
I have a 14kwh pack that weighs 69.4kg complete with all hardware cooling plates and cooling manifold.
I am planning to order the cells in the next 2 months so I am giving enough notice to anyone who may be thinking about buying batteries.

Sorry do you have dimensions and general specs on the cells?

The USD$45 is that the cost price at the supplier over seas?
Even if it were that is still on par with the cost of the 2nd hand leaf cells when they were more available.

[francisco.shi]

The price is the cost price at the supplier overseas, so we would need to add the freight. I am hoping that if I can buy enough cells in one go I can send them by sea at a much lower price.
Nominal Voltage 3.6
Nominal Capacity 63Ah
Weight 969g
Continuous Discharge rate 2C
Peak 5C
I measured the internal resistance and it is about 1.5mOhms
I did a capacity test at 1C from 4.2v to 3v (they claim 4.2 to 2.5 but I was not game enough to go down to 2.5) and I did get slightly over 63Ah (about 65Ah)

I have also made some clamps for the tabs and working on a BMS (one board per cell). The clamping system does not need holes to be made to the tabs and I have managed to get about 1.5mv drop from one cell to the next at 1C. I still do not have a cost for the BMS or the clamps. I have also made a cooling system and mounting hardware but as of now I still do not have a price for the mounting hardware.
I guess I would need to get a quantity to work out a cost and probably improve the manufacturing process of the parts.
