These are not A123 cells. They are the same formular and perform in a similar manner however do not have the high discharge that A123 do. They are good replacement cells for NiMH or NiCD as they have no charge-memory and a longer life than conventional rechargables. They are also robust and forgiving to over discharge/charge.

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 .

schade , ich hatte zwar damit gerechnet das diese zellen weniger kapazitt haben als die a123/1100mAh ,aber mit so wenig :-( .

is good !!!!!

i have test 4s1p long charged and resistance to discharged teperature

is it wery wery good to servo and revever board.

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.

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.

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!

is good LiFePo4 1200mAh really

Similar to A123.

... nabiti 800-1000 mAh I=1,2A

vybijeni 1C I=1,2A V=2,5V 850 mAh 2C I=2,4 V=2,5V - 600mAh vnitrni odpor 1S1P vcetne vodicu 66 m(ohm)

, pri vybijeni vetsim proudem (5A) padlo napeti na clanku behem 7-10 sec.

takze muj zaver - dobre prijmacove baterie
