LG's or Samsungs, and a new four bay charger?

[Mrez]

I'm considering picking up another pair of batteries in the near future and I'm not sure which of the two brands above to get. I tend to build at .25-.6 for most of my drippers on a VTC4 and I found .4 to be a decent blend of vapor, flavor, and longevity of the battery. What I would really like is a battery that has a bit better of a life span at those resistance ratings then the VTC4s. I love em, but my favorite dripper right now is at .25 quad build, and the battery doesn't last for ....e. I've looked at the charts on one of the previous postings, but I don't quiet understand what it is I am actually looking at.

Which brings me to my next question, I already have a 2 bay xtar MC 2, but the damn thing takes an Ice age to recharge my batteries, and since I only have two of them, that can occasionally leave me in a bad way. I was looking at the Xtar Panzer,

and two nitecores

Does anyone have strong opinions one way or another on those chargers? With any of those chargers, would it be safe to leave discharged batteries over night or for extended hours on them (say if I'm on vacation and out of the room I can leave the cells charging for a while and just take em off when I stumble back into the room). Also, how are they on charging times?

As for the chargers, of the options you listed I would highly recommend the XTAR, they make very nice quality chargers. Nitecore is OK but they're sort of middle of the road, the XTAR is more of a high end. As for charging time, that depends on what rate you charge your batteries at. The XTAR does .25, .5 and 1.0 amp charging rates. At 1.0 amp you will have the fastest charge that charger can offer, most non-adjustable rate chargers are set at .5 amp so the XTAR on 1.0 amp setting will charge faster than you're used to.

If you REALLY want to charge batteries fast in a pinch I would recommend the Efest LUC V4, unlike their batteries they do actually know how to make a great charger. Here's a good review - Review of Charger Efest LUC V4 2014 That charger supports .5, 1.0 and 2.0 Amp charging rates and is my personal charger of choice, it can charge a VTC4 from 3.6v to 4.2v in 35 minutes on the 2.0 amp setting.

As far as those batteries are concerned, you would be hard pressed to tell the Samsung and LG cells apart in a blind test, if you're only buying a pair I would go for whichever is cheaper or more readily available.

Either the LG HE2 or the Samsung -25R batteries fit your needs.

Pretty much all of the chargers you are looking at will automatically stop charging when the batteries have reached a fully charged state.

But... leaving them unattended while charging or when they are done charging, for extended periods of time is not exactly good practice. If something goes wrong, it will go wrong catastrophically (as in burn/flames/melted charger)

There isn't really any charging situation involving lithium batteries when leaving them unattended is a good idea.

I agree with your recomendation for the Efest LUC V4.

While I generally dislike the way efest markets their batteries, my LUC has been a rock solid charger. They are currently pretty inexpensive right now compared to a year ago.

That said, the top of the line Xtar chargers are pretty awesome also.

I have a Nitcore. It works. Feels cheap and the sliders bind. it also does not allow different charge rates. Making it a slow charger. Most of the time I am ok with that but it would be nice to bump up the charge rate if I am rushed for time.

Great information guys, thank you much. I had been leaning towards the samsungs to begin with, but had some concerns since I've heard several recommendations for them as VV/VW box mod batteries.

Is there any risk to the battery of using 2 AMP charging rate? Or is that more of an "only if you must" option, with the .5 and 1 amp rates safer and better for the cell.

Regardless, that Efest Charger is nice, and a few bucks cheaper then the panzer, and Illum has the batteries for a few bucks cheaper as well. Looks like I got another website to join.

The lower the charge rate, the less stress on the battery. Both the LG and the Samsung can be charged at 2A. But, this will stress the battery more than charging at a lower rate.

Typically if I have the time, I charge at a low rate (.5mA).

Also, Frequent charging is preferred over running the batteries almost dead and then charging. Li batteries do not suffer from this. It actually is easier on them.

Less stress = Longer lifespan
