i sure wish they would make a 3s 5000 hard case even this in a hard case id like to use them in my truggy hpi firestorm. it really can take a beating but i doubt the battery will without a hard case! anyone know a place to get these in hard cases?

I just bought one of these and the imax b6. the battery is not properly balancing. one cell goes up to 3.6 v but the other only goes up to 3.4. Is this a problem?
 Lisa 4 points
I too have a cell that is low, this cell might be made balanced out to the correct voltage on a balance charge, also it may take a long time too. However if the cell does not the battery can still be used but its absolute maximum performance will not be achieved. I have used one like this for a whole season of heavy usage in an E-Maxx without a problem. Hope this helps.

Does anyone have any specs to these cells? I'm pretty sure the standard LiFePO4 voltage and discharge C rate specs apply (~3.2-3.3VDC nominal) but what is the "Cycle Life". What is the maximum cycle life/count from full to 0% DOD or what is the cycle life/count from full to 80% DOD? What is the MAX charge C rate? What is the manufacturers recomended charge C rate? What is the LVC (Low Voltage Cutoff)?
Now because this product has a slightly higher nominal voltage of 3.3VDC, what is the HVC (High Voltage Cutoff)?
There's quite a bit of "unknowns" on this product as well as all the LiFePO4 products here, esxcept for the A123 cells. :o(

/Ditto on the Lipo's

Ooops, just re-read the specs and the MAX charge rate is 5C. But what is the "Cycle life/count" at that rate?
I know that a high charge C rate and high discharge C rate lowers life quickly. High charge C rate only lowers it also. but what is the cycle count when you charge at .5C (2.25A)?
 Lisa 4 points
i do not know about .5c but i have 1 set in my emaxx that i have used 1 full season now going on 2 seasons, they have 52 cycles on them at 1c balance charge. I am looking at the # of cycle i can get from them also.

for those who had bought these LiFePo4 batteries recently, how are they holding up? Puffing? Still going strong? I bought a few a yr ago & they had puffed & a couple won't hold a charge anymore.
 RICK 10 points
should have mine soon - plan to baby charge them at .5c the first few runs. then probably up the charge rate to around 3.5 amps.
 Lisa 4 points
Had one puffed on delivery. The other 3 are still running strong. I have seen others puff, but this is high usage on a 90 degree day. No problem ever in cooler temps.

Puffed. Low discharge rate of 1C (used for LED lights). Used high quality balancing charger set for LiFePO4. They look great short term, but once past 6 months, even at low discharge, both my packs puffed.

Is the Max Charge Rate 5C corrct on THIS battery?

I have bought 2 kinds of batteries from HK now, both specd twice as high on the Max Charge Rate than the battery label actually says once I received it.

What up with that?
 mwgib123 8 points
Anytime you push high "C" charging, you will take life off of the battery. the best thing to do is the night before charge at1 amp and the battery will last a lot longer. I buy extra batteries so the just used battery can cool down. and when I get home I will put em on a charge.
 Brian 6 points
I haven't maxed out the charge rate since my power supply can't do more than 10A but after 3 charges at 10A they've been taking just under 5000mah. ~30min charging is fast enough for me until I can afford better power supply/charger.
 RICK 10 points
you can charge lifepo4 bats way over "C". but i would not do this for the first 20 cycles. stick to 1 C (5000 mah = 5 amps).
 Lisa 4 points
do not i repeat do n ot do anything but 1c with these bats for the first 20 cycles, and i can only attest to 3c charge. They say 5c but i never pushed it.

I charged mine at 5amps, after running it 30 times there is some puffing but it still is runing fine.

I just bought 2 of these and ran them yesterday .a very good battery. it does not have the punch of a lipo . I would compare it to a 9.6 nmh 4600 . With aprox. 50 percent more run time with more puntch then a nmh battery. good safer alturnitive then a lipo

Bought two of these and connected them in series for a nominal voltage of 13.2 V. Will use them in my full size glider (LS8-18) for supplying instruments and radio. I tested the batteries for capacity and came up with the stated 4500 mAh. These will last for 6-7h flights and I carry a spare NiMh battery of the same capacity in the tail. Voltage stays VERY constant over long periods of time. Keep in mind I only draw 500 mA and 1.5A when talking on the radio. Of course the cables and the battery are protected by a 5A fuse right on the battery. I built an aluminum battery holder to further reduce the risk of fire (which LiFe batteries are not prone to).

Solid battery. Really performed well with some rough use. Shorted once accident and lost a cell. No real complaints.

I use these packs as power for a high performance 2800 lumen, 32 watt bike light. One pack will run my light about 50 minutes. I've run about 15 cycles on both packs. The first 5 cycles I just topped both of them up each day after they sat overnight. I kept track of time to charge, each cells voltage, number of amp hours added and I measured each pack's dimensions. I found that if a particular pack had an unbalanced condition (more than .1 volt difference between cells after disharge) that over the next charge or two, that difference went away. I drained both packs three times, down to about 1to 1.5 volts per cell. The Cellpro Gold 4S automatically did a Low Restore and put both packs back to normal. On Low Restore, with one of the packs down to 0.9 volts per cell, the Cellpro showed that 4.7 Ah had been added. I also measured with calipers the starting dimensions of both packs. After 15 cycles, both packs are within 0.3mm of their starting size. I did drop one of the packs on the cement floor of my garage. The force dented one corner of the pack and caused part of the shrink wrap to crack along the edge. Fortunately this has not affected the pack in any way. LiFePO4 packs can be stored at 100pcnt charge. It seems that charging them, just to top them off is a good thing. In the beginning, one of the packs took about 3 min to top off after sitting overnight and
