Bought 10, two of them had lower voltage, 2.5V and 0.7V. Charged up them and are now showing nominal voltage. Even if they dont perform it was a good price. Soldered a 3S pack yesterday and did some initial tests, charging/discharging. At a 4A discharge they got very warm. Only thing I am not sure about is the end voltage, do I charge them at LiFe setting or LiPo ? End voltage for LiFe is 3.6 and LiPo is 4.2 !

Seems like these need a few cycles to break them in. Then they work fine. 4S pack performs like a 3S LiPO of about the same capacity (1200mAh). I am buying more!

hallo,muss mich leider Patrice DEBUT ,anschliessen.ich bekomme auch nur 650-700mAh eingeladen ,bei einer entladung bis 2,2v .

Discharge curve good

Nov 14, 2007

Run this cell at a discharge of 5-10C constant and got around 1000mAh capacity.

The higher the discharge the lower the capacity seems to be.

I have been told this is normal for LiFePo4.

So as far as I can see, they run normally.

LIFEPO4 test

Nov 14, 2007

Tests/mesurs sur 8 cycles charge/dcharge ... 10C: 12A 2.55v moyen pour 580mA de capacit rendue.

Peut mieux faire. Rien voir avec les A123 originaux. Dommage, un espoir du.

30c cell

Nov 14, 2007

These look like just the ticket for some of the smaller stuff. Quick test after assembling 3 cell pack showed them to hold voltage under load very well (9.0v at 15A as they were delivered - havent charged up yet!). Dont think Ill ever bother with lipos again!
