Re: LifePO4 Lifespan (not cycle life)

Interesting old thread! I've tested hundreds of Winston LiFeYPO4 cells lately, mostly from 2011-2012, after a working life in electric buses with multiple charges per day! about 80% of cells were still very good, capacity between 150-165 Ah (a new cell from those years would have had 175-180 Ah?) So...

Joachim, you don't know this chemistry, they don't really care about it, it is sooo different than 18650 or lipos.
No it's not...

but the good thing is that '100%' is usually 4,1V and probably a little less here.

Re: BMW i3 120Ah Cells for sale - EU "Austria"

I would advice you to not try to separate these modules into cells. the outer case is connected to the positive pole (iirc) and the cells are glued together very well. also these modules are much to nice to disassemble ;) also be aware the cable coming from the module is an aluminium cable, so if yo...

Re: FS: Tesla Model S cells (Europe)

Today arrived a few cell samples from Boekel for my cycle life tests and comparsion with other industrial 18650 cells. For some time I was looking for cells with known history with the lowest possible mileage and calendar age. I have measured nominal capacity/energy at calibrated 4-wire battery tes...

Re: Conversion Vectrix VX1 with tesla modules

Could it be nickel plated aluminium? There is a different shine on part of the bus-bar plate...as you can see in the bottom left corner here, I think the plating is different there: http://boekel.nu/foto/17/2017-02-tesla/b.jpg http://boekel.nu/foto/17/2017-02-tesla/image84.htm Bare aluminium also do...
