Lithium-Ion is not a specific cell chemistry, but rather, encapsulates a broad range of chemistry options. IMR IS li-ion. (Ion Manganese Rechargeable).
The more common cells you see, often sold with protection circuit, are lithium cobalt chemistry, or ICR cells. This cell type is usually the...
Your cells are just wearing out and you are experiencing a combination of reduced capacity and increased cell resistance (reduced performance) as a result.
For the record, a 1.5Ohm load on a LiCo chemistry 14500 is over the maximum discharge rating of the cell and will wear it out quickly. For...
Use spacers to complete the circuit. 15mm diameter steel balls are commonly used. Also, many places that sell these cradle chargers sell optional spacers. You can make your own out of anything conductive. A piece of dowel cut to length with aluminum foil wrapped around it will work. A wad of...
Series wired NIMH packs are naturally balancing since you are supposed to overcharge them a little bit anyways. All smart chargers technically overcharge the cells some. There is nothing wrong with this. During the slightly overcharging period, out-of-balance cells will catch up to the others...
I've used em on my BB with a 510>808 adapter and they worked pretty well for me... I had pretty decent luck with them overall. They produced decent vapor most of the time.. However, I did have instances that are just like what you describe- the harsh throat hit and very little vapor. I could...

Great prices, they offer very good specials frequently, cheap shipping options and fast shipping times.
I picked up a 5 pack of delrin drip tips for like a dollar from them a couple months ago. I don't...
I have taken ordinary and LR 510 cartos that were fowling up with gunk, and just put them in boiling water for about 45 minutes. The hot water and agitation of the boiling seems to break free most of the crap and cleans out built up residue in the media and wick. Best to do this with plenty of...
Now that I am using it a little more, things are getting better... Seems like the best way to get things moving along with these is to prime them up by direct dripping on the atty up top... And just aid the wicking with a few manual drops here and there.
I have to be honest, the vaping...
I just made the mistake of including a pack of CE2 XL fat-wick clearos to try out with my new juice order- all vg. I immediately noticed a wicking problem. I may have to just go back to the regular cartos/atties for for this batch of liquid. I do like the sheer quantity of juice this can hold, I...
So.... You're trying to use buck regulated LiCo cells of ~500mAH true capacity to drive an 8C load?
This is the sort of behavior that will lead to ecigs getting a very bad name and reputation. We can only be thankful that the protection circuit prevented you from success.

I agree with the sentiments against littering with butts. I always did the "twist-off-n-trash-it" method as described by mccawley. I did give smokers a hard time about chucking butts wherever they pleased even when I smoked.
Having heard so many good things about the general performance of KR808 cartos and V4L juices I decided to give them a whirl. I however, didn't have any interest in buying a new battery system as I have a perfectly functional BB (my only ecig) with 4 IMR14500s and a Pila IBC. I started with this...
What do you think is going to last longer... A design where you have to constantly remove the little atty threaded device to charge up, or a design that moves the wear and tear at charging time to a separate larger heavier duty thread?
You don't need a pass-through if you run an 18650 mod.
I have not seen any thorough testing performed on the eGo to determine if the charging method is proper.
Considering the very high failure rate of ecig "kit" batteries, I would lean towards believing that the chargers do NOT properly terminate the charge. Protection circuits do not produce...
Definitely need 4.5Ohm atty's for the 7.4V config. For the 3.7V config, keep in mind that even a standard resistance 510 based atty will be over-driven, since 510 based batteries operate closer to 3.2V. Fresh from the charger, an 18650 can deliver over 4V unto the load of an atty. Use either...
No, I would not tolerate ecig failure rate for other devices, and I won't tolerate that failure rate for ecigs either, which is why I don't own any of the devices that seem to be repeatedly discussed as having battery or charger or atty problems here.
I only own 1 ecig, a battery mod device...
Initial state of charge of an ICR cell is commonly higher than IMR cells. As high as 4.25V as apposed to ~4.15V. While an IMR cell may charge to 4.20V or higher, the actual state of charge is rarely that high. The maximum state of charge for an IMR cell is reached when all of the ions have been...
One only way to find out for sure would be to use a DMM and see what happens when the "light turns green." That means stripping some wires on the chargers and putting the DMM in parallel with the charge circuit. It's also not a bad idea to repeat the test with the DMM in series with the charge...
There are 2 possibilities:
1. The eGo electronics naturally buck the voltage in reverse as well, requiring a higher charging voltage than other direct drive devices. This is common with protected LiCo chemistry 3.0V cells that are actually 3.7V cells behind the regulator. In the case of those...
Put me down for a slight maybe. If I can get out of work early that day maybe I'll swing up there. I don't have much ecig stuff to share but I could bring up plenty of examples of chargers for mod users. The good, bad, ugly.
