C-LiFe 18Ah LiFePO4 prismatics

[Lock]

Can't find any reference on ES to Taiwan manufacturer C-LiFe Technologies, Inc.

They make a 12.5Ah cell

...but also these 18Ah prismatics

They sent me a PDF of specs for these 18Ah cells that I have attached to this message, but some pages from that PDF:

The internal resistance at <4mΩ seems good...

Max. continuous discharge at 12+C seems powerful (for LiFePO4)... and I find it interesting they're saying charging at -10°C is OK.

Odd to see cycle life for LiFePO4 only expressed to 300 cycles. Haven't asked them what 1000 or more cycles look like...

They have a vid on YT that has some nice cell manufacturing porn:

Bottom line, this is a new-ish manufacturer that claims to be making fairly high-quality cells...

Well, yes the cylindrical cells do display a striking resemblance to PSI cells as does the format of the performance specification graphs, but there is some evidence that they could indeed be from a new and different manufacturer utilising many of PSI's manufacturing methods/designs.

Firstly, within the company promotional video i noticed that the 'Lego blocks' (snap together cell retainers) are a different design to those made by PSI

Also, PSI dont offer prismatic form factor cells, nor 12.5Ah cells (only 10Ah & 11Ah cylindrical)

Whatever the case, for LiFePO4, the 12C 18Ah cells look much more space efficient and easily built into packs than the traditional PSI/Headway cylindrical cells. It would be interesting to know price and availability in small quantities.....?

The physical dimensions of the 18ah cells are just perfect for my ESR scooter's battery pan. I have been on the perpetual hunt for the correct size/dimesion high C cell like that. I am afraid the 20ah A123s just won't fit. And if they really perform that well, then all I can say is I would really love to try some. So if anyone fiqures out how to obtain them in small quantities, please post up here.

Great find, Lock. Thanx for bringing them to our attention

Really need to know pricing and availability, plus info on capacity life long term... And, how much low temp discharge and recharge affects cycle life... and how responsible seller(?) is with warranty claims... lots of questions!
