This has been a fantastic battery for the last 3 so years, one thing to mention if considering purchase in late 2018.

While the original release of the LG HG2 was in 2014, production has become available in Summer 2015.
A 20 amp, 3000 mAh milestone is, in some way a holy grail of stats.
A battery that can both be high-drain, and high-capacity is just what everyone wants.
LG Chem is on a rolling schedule of releases and research, all planned years in />An average of between 6% and 10% increase in battery performance is expected, compounding yearly.
That means, taking into account the battery specs and LG Chem's release schedule, the LG HG2 will likely be a good contender for one of the best 18650 batteries for some months to come for high-drain applications.
That said, there are many cases where the newest 18650 battery with the latest specs never gains mass adoption.
That can be due to a number of reasons including a quick upgraded release, unforeseen safety problems, supply chain insecurity, market ignorance, and so forth.
It's for that reason I am not crowning the HG2 as the new king on specs alone.
If you are interested in maximizing both amperage and capacity you should consider this cell because it doesn't get better at the moment.
However keep in mind that fast charging will decrease the cycle life of the HG2.
Charge Voltage Standard, no comment 2.
The nominal capacity of the HG2 is determined while discharging at these values.
When discharging at its max.
This has likely led to the claims that the HG2 under />However many of these tests neither distinguished between the standard discharge vs.
What is important to note is the cut-off voltage of 2.
Cells shall be discharged at constant current of 10000mA and 20000mA to 2.
Cells are to rest 10 minutes after charge and 30 minutes after discharge.
Most 18650 cells cut-off at 2.
We see a similar parallel between the LG HE2 and HE4 fast discharge conditions.
Most people do not want to go below 2.
Discharge Current A 20 amp cell - very good.
Note that this is the cell's maximum continuous discharge rating.
Some people seek pulse ratings, which are often fabricated.
Remember: a pulse is адрес страницы as current over time.
Without stating time, lacks meaning.
An example of a proper pulse rating would be 30 amps 2 seconds.
A cell rated at anything above 30A, without an attached unit of time is, in essence meaningless.
None of the big three Panasonic, LG, Samsung make an 18650 battery rated at over 30A.
Note there are four top-cap connection points on LG 18650 batteries.
There should be no rust, discoloration, spots, burn-marks, excessive scratch marks, or anything else out of the ordinary.
As this cell has been recently produced Summer 2015 batchthey are new and the steel will reflect that.
If your new HG2 has any of the abnormalities listed above, request a return with your vendor and suspect a counterfeit battery.
This is the negative terminal, or bottom of the LG HG2.
There are a few scratch marks usually circular on the bottom even on brand new cells.
This is normal and from production, as the cells are tested and charged and the steel scratches easily.
Do not do this with metal calipers as you may short-circuit the cell.
If you are making a pack, note they are a little bigger than 18mm.
Let's call it 45g from measurement error.
Where does that leave us?
Albeit I will weigh a few more later just to confirm, a 3 gram discrepancy from maximum value does not cause alarm.
Discharging the LG HG2 Accounting for the test's environmental temperature.
This is five points off an ideal temperature LG Chem's test opted for 25 degrees Cbut at this difference the efficiency loss is negligible and I will go ahead.
I enjoy charging my 18650 batteries on the VC2.
The big display just makes my life better.
This is our 18650 discharging unit.
The readout is volts that last digit is a V and not a U if you were wondering.
As you can see this battery is running out of juice, and the discharge test is almost complete.
This unit runs off of USB power and as such it has an unfortunate current limit of 3A.
For the first discharge test I used a 2.
The capacity is 40mAh hours short of the rated capacity of 3000mAh.
Does this mean the battery is not meeting its rated stats?
Here's what I mean.
The Yes For one, the cell in this test is a few months old.
A lithium-ion battery will lose some capacity every month it sits in storage.
When we are concerned about 40mAh, some of that is attributed to its age.
It is more accurately as a 2960mAh battery.
Discharge test two confirms the HG2 capacity at ~2960mAh.
For discharge test three I changed the current to 0.
As you can see, at lower amperage discharges, the capacity goes up.
In this case, about 6 mAh were gained.
увидеть больше this image I overlapped the 2nd 2.
If you look at the bottom-right здесь the chart, the difference along the X-axis mAh is small.
However the Y-axis of Voltage shows a bigger difference.
You can think of this as the batteries lasting about the same amount of time, but the low amperage one share Поляризационный фильтр HOYA CIR-PL HD NANO 72mm thought more working power.
A higher voltage for longer results in more watt hours.
The watt-hour rating can be argued as just as important as the capacity mAh rating.
Unwrapping посмотреть еще PVC There are three markings to be found on this particular LG HG2 battery.
If you unwrap your HG2 and notice it has very different markings please leave a comment describing them.
Here is another look at the top-cap in all its glory, this time without the heat-shrink PVC or washer.
Conclusion In the beginning I claimed the HG2 may be the best high-drain battery available right now.
Unfortunately the cell I tested does not quite meet its mark at 3000mAh.
It however does clock in at 2960mAh.
Even if we call a 2900mAh, or a 2800mAh battery - it still surpasses the Samsung 25R 2500mAh and the Увидеть больше HE2 2500mAh.
There are cases which this can be shown wrong, in particular in high-drain tests at 20A which I did not perform.
It is however, highly unlikely that the capacity will be effected enough so that it can not exceed 2500mAh.
It is for that reason I am fairly comfortable claiming the HG2 is quite a beast, and I crown it as the current king of high-drain.
If I need to purchase these batteries… 36 no ….
Be sure to buy from reputable vendors only, such as ILLUMN.
My extras are stored in a backpack in the closet, as far away from both elements as possible.
This area, but not in the backpack, is where I also store my mixing supplies.
The LG HG2 18650 is a great batter if used properly.
Example, when running a dual battery mod at no lower than 0.
Most who runs tri or quad battery mods tends to go with a Sony VTC5A if 18650, sometimes using an adapteror move up to the 20700 or larger cells.
However, it does perform quite well for those who still runs the even older than the HG2 Kangertech Subtank Mini, one can vape all day long, even with the 0.
I love these cells so good, had to purchase two more sets from RTD Vapor during their 2018 Black Friday sale.
I am thinking in rebuilding some laptop batteries one from my Lenovo X230 and another 2 from a Powerbook G4.
Dear Sir; I really appreciate what you do for all us.
As many I нажмите для деталей an amateur using this stuff but I am getting nervous due to LG HG2 explotion that sadly happened to Andrew Hall.
Thank you so much.
Wayne — I recently bought a few of these cells and, in addition to the typical 2 lines of black dot-matrix LG model, date, and batch codes, there is a label stamped on the wrapper some kind of thick white paint.
It produces slightly raised lettering reads:!
I bought 3 of these batteries for my wisemec mod.
Charged theme overnight on the 1amp setting in my Efest charger.
Will this give the cells a proper charge?
When I put them in my mod it only read 99% Very thorough review, thank you!
Newbie question: I intend on using 2 of these in a vaping box-mod Joyetech Cuboid 200w.
Does it matter if I charge from my PC or from a wall adapter or from my car?
Or should I purchase a separate charger?
Thank you in advance.
Someone has an idea of the cycle number reachable with this model?
I have heard in the 3 quarter of 2016 LG is limiting the sale of these batteries and will not offer them to consumers.
They have also added a new caution label to the wrap.
I charge 3 batteries like these on my nitecore i4 v2.
Hi… i use this battery for my vapor mod.
I have 3 of these batteries in a box-mod like yourself.
In my experience, the batteries will likely be in series, but with regulated box-mods, the voltage regulator be reducing the voltage to a greater or lesser degree depending on the power setting you have.
The current will make up the rest to make the power w as long as the batteries have enough current to deliver.
Anton Sorry, my last comment should have read….
Thanks again ; Mark Anon Thanks for the advice on charge current at end-of-charge.
The only thing that is concerning me is the charge current at the start of the charge, which ramps up to full current I have set the charge current to 1A at the very start of the charge.
Am i right in saying больше на странице this battery chemistry would do better with a small trickle current for a short period at the start and only full current in the middle of the charge?
My charger starts high anmd tapers off as the charge progresses.
Really appreciate your thoughts on this.
Mark which has more cycles, LG Chem 18650 HG2 or the Samsung INR18650-25R5 over 250 cycles?
Saimon — Unfortunately, this is not enough information to determine whether it is a fake cell.
However, any markings on the naked steel are a positive sign and can be used as weak evidence.
When LG produces a batch, there are slight very small discrepancies in performance.
This can увидеть больше an issue when building large battery packs where any variation will нажмите чтобы увидеть больше stress to individual cells.
This particular grading can result in a maximum of about a 30mAh difference less than one volt.
I would be interested to know if there are any other environmental differences not taken into consideration.
JO — Hello Jo, with these codes we can determine the location, assembly line, batch number, and potentially other details.
The generic white sticker and box they come in are normal, as these are low-cost packaging options that many distributors will use.
The matte ring and ridges are a positive sign.
At this point, I would suggest performance testing them with a charger that has a capacity read-out.
Your codes do not look suspicious to me and I was able to look up data correctly with them.
Bob — The LG HG2 is an 18650 lithium ion li-ion cell.
перейти на страницу is also lithium ion li-ion by nature as it shunts lithium ions ссылка на продолжение the positive and negative terminal.
LiFePO4 describes a chemical composition, which the HG2 is not.
The HG2 is a 3.
Alex — It will depend on your box mod.
If they are in a series, the voltage will increase.
In parallel, capacity will increase.
Mark Bartlett — A 1A charge current to a cut-off voltage of 4.
However, 18650 batteries should taper the current at the end.
All 18650 cells are now rated at 3.
The only thing that changed was the regulation that determined the method to do the voltage average.
To be safe, I would contact the manufacturer of your charger and ask them which setting is safe for lithium-ion 18650 cells.
Will i be ok to charge these cells individually on a RC Lipo charger.
The charging current i have set around 1000mAh and charge voltage of 4.
Will that be ok for these batteries?
The charger has settings for both Lipo and Lithium ion, but the Lithium Ion setting is fixed to 3.
I have to set it to Lipo which is fixed at 3.
Would really appreciate your help.
Are these in parallel?
And so does that mean I have 3x as much max amps to work with on the discharge but the same voltage?
I bought 4 of these on amazon, when I received them they had a sticker over the numbers except for where it says 1865.
I pulled off the stickers and the numbers for each battery are identical.
Top: LGDBHG21865 Lower: 0322K181A1 Hey guys, just wanted to get some input on my HG2s.
I got them and they seen to be performing well but I want the peace of mind knowing they are authentic.
I noticed a few things.
They have no serial numbers.
They do have the matte ссылка на страницу ring and the proper ridges from what I can see.
I unwrapped mine and the number on it is A25123.
All other things being equal, my newer HG2s do not last as long as my older 25Rs.
The HG2s seem to lose kick mid-day while the 25Rs will last me a full day of work.
If you have a way to test capacity either with charge or discharge you should be able to confirm this.
That is interesting indeed.
Not all Grade A batteries are stamped.
For example, many HG2 batteries you see today March 2016 were meant for a client in Japan but ended up on the open market in Hong Kong, China, and ultimately sold worldwide in small lots.
You might have one of these cells, or maybe not.
So we can not only use labels to detect fake HG2 batteries.
I would be more interested in hearing about your grooves.
If you send us a photograph we will take a closer look for you.
Battery bro your definetly the ultimate battery gu-ru but a question you failed to mention what is the life exptancy of the lghg2?
I have reviewed the sheet but that is the only mention of weight.
I would worry if both a large weight discrepancy at your discretion, perhaps around 3 grams or more and corroboration with other things like lower-than-expected capacity.
If you are interested in the variation in length and height it is provided by the HG2 spec sheet: Diameter : 18.
I have seen digital calipers and scales that are not properly calibrated which can easily throw someone off.
I recommend checking out something like XTAR.
Newbie here just wondering if i can charge my LG choco batt using a regular 4 bay eneloop charger?
Thank you in advance Paskal Yes it is likely you have purchased a fake.
We can add it to this blog post with your permission.
GoranK Many mods are able to charge 18650 batteries safely, I recommend you contact Evic and ask them for their advice.
A good charger will always provide a safer, more complete charge.
Rust may also accumulate faster from salt spray if you live near the ocean.
In any case, a cell with rust should be recycled immediately and never used.
I would be very skeptical of the cells.
If you send us a picture we can help you verify them.
While IMR and INR are both Lithium manganese based, the HE2 20AHG2 20Aand HG6 30A, under development are all considered Ni-Rich high proportion of Nickel.
Nick Jennings Thank you for your testing Nick it is very interesting to us.
I hope we will see more real-world tests to accompany our findings.
I bought another 20 for a 13s3p 1000W ebike If your goal is 1000W, I highly recommend 3P or even 4P, which correspond to approx 7A and 5A.
Finally, at 5A or higher load, the 3.
I must argue with your statement that you said about the LG HG2 being a beast.
My real world https://csgoup.ru/100/otrazhatel-deko-light-20-reflector-luna-15-930188.html product testing of the LG HG2 vs Samsung 25R batteries was done using the exact same mod and exact same sub ohm tank and exact same type of sub ohm.
Brand new fully charged LG HG2 batteries.

In conclusion of my real world usage testing i found that the Samsung 25R batteries were better for the situation that i tested them at.
The LG HG2 on paper is a great battery but the fact that something is not right when used is not sitting well with me.
Now, i know this is not just the fact that maybe i got a bad set of LG HG2 batteries simply because i have purchased 3 sets of the L:G HG2 as i really wanted them to out perform my Samsung 25R batteries.
I recently purchased a set of these from a local vape shop that claims to sell only authentic products.
Thanks I bought 2 x lg hg2 3k amp batteries for my brend new Evic VTC Mini mod.
Dear Anton, Thank you so much sincerely for your reply and details.
Have a wonderful day.
Manuel Yes the math makes sense.
Santosusama Yes, you should charge your brand new batteries to full 4.
Yes, the Nitecore D4 can charge these batteries and is sufficient.
For 2-3 months of storage I recommend bringing them to around 40% charge, or 3.
They should be in a cool, dry place, optimally not exceeding 25 degrees C.
If you will store them for longer, you may want to top them up every quarter to make sure they never drop below 2.
If you want to store them fully charged, do it at 4.
Brandon singletary Please email us at supportbatterybro.
Thank you so much for the review.
I ordered 4 of these a month ago, still waiting to be delivered, excited?.
I want to источник that if you may please answer, especially for noobies like me, do we have to charge our brand new batteries before we use them or first we have to drain what is inside and then recharge them?
Or it depends on the battery chemistry in this case for these LG HG2s for example which one is the correct thing to do, use it right away as it is or charge them before the first use.
I have a Nitecore D4 btw is it sufficient for these?
Lastly apologies for too many questions what must we do to keep them alive when we dont use or store them lets say for 2-3 months?
Thank you so much in advance to all.
I want to use this model for E Bike 48v 1000w.
I need to join 13 18650 batteries in series to achieve the 48v and want to do two sets of 13 batteries 13s2p.
I will for this project??
A laptop battery pack includes a custom BMS that is special for your particular computer.
There is unfortunately not an easy, safe way to DIY a battery pack for your own laptop.
But if you do it yourself, you likely need to be an engineer to do it safely.
Will this new one work great?
However my wife wanted somethig with a little more life.
Mind you we both run a 75w tc sigeli mod…single battery inside!
So of course battery drain is a serious drawback.
Thank you for the great easy to understand review!
Keep them coming as tech improves!
Aaron So for a device with a max input current of 16amps the dna40 would you use these HG2 or the new green 25R-R5s?
I generally run my Фотоальбом фоторамкой 20-40 watts.
Also what about authoritative Каминная вытяжка Faber WEST ANGOLO H-EP WA 100 speaking the DNA 30 with its makes input current of 12amps?
And finally in a single battery mechanical device usually running a 0.
Thanks again for the great write up!
Awesome write up thank you!
I just ordered 2 of these from an ebayer with really great feedback who deals with only batteries, he swears they are authentic all over the listing.
Is there anywhere I can take the battery maybe источник статьи plus?
All I can do at home is physical inspection and weight.
I am looking into buying a charger, maybe I can find one that displays mah or something to help verify?
As far as I know my multimeter I own wont help at all.
