And thinking deeper about it, if 10 year old Moli cells perform that good, then how ones manufactured this year do?

I just ordered 3 of the moli from same seller.  Almost did about 3 weeks ago when I had a chance to snipe them at like $15 but hadn't heard anything about them so I shied away.

I Have a MNKE 26650 400mah that I overdischarge up to 1.8v and wont charge in my other charger except on my ML-102 V2, After a few hours its now full charged to 4.2v.

Do I have to worry about anything that happened to this battery?

Thanks

Many charger cannot pick up a cell with a voltage lower than 2.2V, so I think it's normal that most chargers won't charge this cell.

What cause this over-dischage, was it a boost driver? Under load the voltage must have been lower than 1.8V.

Actually an error on my part, Used this to power my 2xD operated Fan and forgot to turn it off, The Fan stopped working and when I checked the voltage its at 1.8v. I used a stock driver from one of my lights thinking this could act as my over discharge protection circuit but I made a mistake almost causing killing a barely used battery. Currently using a protected 18650 batts in the Fan.Laughing

First post here guys.  Newbie to this new world (but not to the interest Smile ). 

Just ordered the King Kong INR26650E.  N.Shock or someone, any chance you can do a discharge test on these to compare to the ICR?

Don't be surprised when you actually get them, that it really is a King Kong ICR26650E

Agreed, but I did contact Ric @ CNQG and he assured me he has both and changed the website to reflect that. Let us know what you end up receiving.

Thanks Smile  Here's to hoping..  

 

Found some discharge graphs to compare to N.Shock's ICR..  no time on these graphs though, but if converting correctly looks like a bit more run time..  Either way looks good:

Can anyone say what size magnets (or better yet link, or ebay link) I might need to get my kingkongs to work in my TrustFire tr-j12?

It's good to have you here, binaryman.

Did you know that there are only 10 types of people in the world:  those who understand binary, and those who don't.

The little rare earth magnets work perfectly. You can order from overseas or get them from Harbor Freight, 10 pack for $1.89:

Ok. I wasn't sure, as I read neodymium doesn't conduct 'as well' as other metals/magnets, didn't want a current issue.

 

Also, better to get smaller diameter ones, or like 25mm so can tape in place easier? What's best way to keep them from moving around with a bump?

I don't own any INR26650E. So no comparison from my side. Sorry!

Sorry forgot it, but I won't use magnets between 26650s

You know, I'm not sure on that. I only use the magnets for charging purposes, but I read somewhere that IOS shipped their JM05 / King Kong combo with extra magnets - here's a picture from Foy's review:

These look wider and flatter than the rare earth ones I recommended. However, I can tell you that the r.e. ones are pretty hard to move; I can't remove it from my battery without using needle nose pliers.

I'm using these ones and they are very strong and work great with the King Kongs & my TR-J12..................I also put tape around the batteries to prevent the magnet from any jars that may occur......doubtful, but better safe than sorry.

I used to use magnets for battery, but I heard zzzz noise from tailcap (If magnets at tailcap)

Because It conduct with spring at tailcap.

 

So I made some button for battery, bend corner of piece of copper or aluminium.

I've just taken pics for you.

Sorry, but that looks dangerous as all hell.....you don't need a magnet on the end battery for the tailcap........at least I never have. For the TR-J12 I put 3 King Kongs together and placed a 8mm x 1mm magnet in between the 3 cells, thus I only need 2 magnets and tape those 2 joints.

Just got my battery space LiNiCoMn cells...

Deans connector an springless charge cradle

Out of the box cells were ~3.7V

Current climbed up to 2A, where I have it set to max to keep C<1.  Waiting for Vbatt to climb....

Heres something strange... Charger tops out at 4.2V like it should (which seems suspicious so early on in the charge cycle), but my Fluke only reads 3.97V.  Anyone know whats going on here?  Its never done this before with Panasonic 18650 cells.  Usually the charger is a little off from the meter... but not way off.  **EDIT** just figured it out... loose contact between the meter and cell.  fixed without incident.

Battery space 3600 LiNiCoMn Cell#1 result:

I discharged the cell from 4.20-3.15V, at 1A and got 3689 mah.

Battery space 3600 LiNiCoMn Cell#2 result:

I discharged the cell from 4.20-3.15V, at 1A and got 3720 mah.

Battery space 3600 LiNiCoMn Cell#3 result:

I discharged the cell from 4.20-3.15V, at 1A and got 3633 mah.

I couldn't resist, before discharge testing it I loaded up cell #3 and took a current measurement in the direct drive HD2010... Not bad at 5.45A, I didn't test it for very long though, maybe a minute or two.

These are the 3600mAh cells - that reading on the first discharge cycle, it could conceivably improve after several correct? Nice to see someone selling batteries with honest capacity.

Thanks for the info, kramer. I'll refer to this in the OP.

That one I am not sure about, but at least initially out of the box they are rated honestly.

Sure np... eagerly waiting for others to post their results too.

I don't think those Keygos cells I posted have protection. Site says they do, picture tells a different story. Maybe you should put a small disclaimer next to the listing.

BUMP for updates to my post #114.

Just a quick tip on the battery space 3600 LiNiCoMn.  Since the +B is so big, flat almost looks like the -B (and I was bored waiting for the discharge capacity test), I got a little creative with the sharpie pens.  Safety first!!
