That seems a high price for used , you need to pressure your supplier for a reduction... New cells can be bought for less....OffGridInTheCity said:My actual cost (no including pack building labor) has been $307/kwh so far (2018/2019) buying 'good' (95% original specs) used batteries from Alarm Hookup and similar.
Generic said:The $100/kwh is manufacturer direct pricing in bulk (multi-million cells). We will not see that pricing at retail for quite some time, if ever. And I don't believe that $100/kwh includes the cost of pack assembly or anything, just the raw cells, correct?

When I found these 1,5 month ago they went for 210. So no price dropping in this case.

For comparison a fairly high capacity NEW18650 holds 10Whrs ... 100 would hold 1KW ...$2 each gives a price of $200/KwHr on the chart ...
We are reaching the point where re using is not sensible ....
Look at the price in 2010 or even 2014 ... then it made good sense ....

It's almost what the running cost is vs purchase cost. Just like buying a car that has more HP but the mpg is your running cost. That's why paying over $1.50 per cell isn't worth it if it comes out to $.16/kwh if your local utility is only $.12/kwh then you will most likely be ahead if you were just on grid.
The one thing is that even though the batteries do degrade over time, it's not as if after 1200 cycles it will not be able to produce anymore, but maybe produce at a lower capacity.
