Ok, I replaced it with this.
"First of all, any battery that has "fire" in it's name is not suitable for use in multi-cell lights. This is because even if they may be rated at the same capacity, they are most likely not equal and could become unbalanced under high loads."
As for using them extensively, I would personally not trust them that much. If they were in my DRY rather than name brand batteries I am not so confident it would have ended so well.
Much better. I agree about the time your DRY was turn on in your luggage. You were darned lucky regardless of what cells were in it. While I did say “extensively” I did not say “exclusively”. I prefer my Panasonic cells to the Trustfire cells also and feel safer with them in my multicell lights too, even in unprotected form. I monitor my cells voltage in multicell lights and only run in sets that discharge at the same rate and check in at the same voltage. I also have several TF Flames that are matched quite nicely and that I trust. As for any other ***fire brands, I try and avoid them like they were covered in syphilis!! 
True, I guess your right. For single cell they are fine, they may not give the best run time or performance but they will work.
Ok, the 18650 section is done. The smaller battery section is still a work in progress.
How important is it to prevent overdischarge of a single cell?
There is a discussion on the BLF “Protected Circuits” forum.
Important, but as long as you recharge the cell right after you over discharge it, it will be fine. If you don't it won't be good for the cell, but it certainly won't explode or anything of that sort.
The AW 2000mAh tests worse than the CGR18650CH at 10A, so I wouldnt recommend it for 10-20A. Anything above 10A should currently use the AW 1600mAh (its rated for a max. of 18 or 24A IIRC..).
Also, for smaller cells, you could also recommend Efest cells. They got some good ones.
Ok, I'm going to actually get rid of that "guide" thing and leave just the comments.
Any smaller (than 18650) batteries I should include other than 14500, 18350, and 16340?
And you got the APR18650M1 twice. :)
I'm aware, I put it in there twice because I wanted it under IMR (since it does such high currents) and under LiFePo4. I understand this is not technically correct since it is not LiMn cell, so maybe I should remove it from the IMR section?
Technically speaking, the CGR18650CH isnt LiMn either..^^
But I would keep LiFePo4 cells out of the LiIon lineup, those are too special and only very few people actually use them.
Btw.: what about 32650, 26650, 26500, 22650, 18500, 17650, 16650, 14650, 10440, 10180? (yes, I'm here to molest you)
Oh, and where did you get the graph of the Sanyo UR18650W? I ordered W2 and WX recently, waiting for them to be tested..
Yup, it doesn’t belongs in IMR section.
True, but I feel it should be there. I guess I'm sorting by function not strictly chemistry. I'll leave the LiFePo4 batteries in for the smaller batteries at least because some lights can take a 3.3v battery but not a 4.2 volt battery. 16650, 18500, and 10440 will be added later today when I get a chance. 32650, 26650, and 32600 will be added at some point in my 3rd comment which is for bigger cells.
The graph actually came from the datasheet (which I did link to already 
), which is here.
Ok, if both of you think that it is getting removed now. :)
Thanks — nice work… very useful.
On the subject of XXXfires, maybe it’s worth mentioning the lifecycle of a fake:
- laptop/recycling pull (or worse, as we’ve seen little lipos wrapped in 18mm tubes)
- new shrink wrap from taobao (EDIT: worse than I thought "Make" your own UltraFire 18650s! — even shows Panasonic wrappers at http://item.taobao.com/item.htm?spm=a1z10.3.0.77.saBKb5&id=10193523421& )
- off to ebay (or a semi-reputable vendor that’s being cheated)
Scaru, if you continue to excel in this manner, you will have to "drop the diaper", and start wearing long pants.
Keep up the good work!!
begging for a spreadsheet…. i know some do not have excel but open office is free and i think it would solve a lot of organizational problems. my apology if there is a spreadsheet in here somewhere i just could not wade thru it all
ken
I have excel, what would you like in the spreadsheet?
Ok, done with the smaller batteries. Tomorrow I will tackle the larger batteries.
