>Not interested, V-nominal is a little too low for use as a single cell. Todays emitters have a Vf that ranges 3.5 - 4.0V when driven. Even with two cells in series, still the Spec’d capacity is too low. Now if you are rating AH capacity at a higher “C” load, that could change things a bit.

>These cells are more appealing with the higher V-nominal. What “C” are you discharging at to get the Amp-hour capacity rating? Those are really good prices too.
Do you have a www store?
But these are LiFePO4’s (judging by nominal voltage), which are infinitely superior to classic Li-Ion’s in terms of safety and lifespan. :Ц
Thank you for you kindly help.
these three battery the max continuous discharging current（A）are 17.5, 7, 6.2
yeah,our store:www.xinchibattery.zxq.net

You’d be surprised it is much easier to screw up a Lifepo4’s chemical composition than it is to screw up a LiCo cell. I’ve had several Lifepo4 cells die after just a few gentle cycles.
Mind teaching me how to do it? I have a single ANR26650M1A which I abuse all the time - overcharge due to using 4.2V charger, overdischarge all the time (no low-voltage cutout on a DC/DC boost converter), charge at over 2C (6A for 2.3Ah cell), and it still is alive, after over a year of such abuse.
+1 I have a rcr123a that I have discharged down to 0 volts multiple times and it stills works fine and retained most of its capacity.
I’ve had 3 different brands of Lifepo4 cells die very quickly. Infact out of 8x 14500 Lifepo4’s I bought 2 were DOA, and 3-4 died within about a year after just 4-5 cycles or so. I had some A123 18650’s go to 0v just sitting in a drawer for a few months. I had one Lifepo4 RCR123 die after the first charge.
Don’t get me wrong if made correctly, they can handle quite a bit of abuse, but if made incorrectly they are rubbish.
we are professional lithium battery manufacturer, our battery has passes CE,ROHS,UN38.3 etc certificates, we can assure the quality.our wetsite:www.xinchibattery.zxq.net
I used A123 26650 LiFePO4 cells for years in homemade battery packs for brushless RC vehicles. I swear by them. In fact there is a huge community of RC airplane enthusiasts who will tell you that they will take more of a beating than any other chemistry available, and keep bouncing back for more.
Can’t say anything about other manufacturers however.
we can use this kind cell to make portable power, also called power bank,see following pictures:
