"new" model LG INR18650 HG2L

HydrAxx · 2019-09-05T04:07:27.000Z

Here are the only information of changes and contributions, that I could find on a Vietnamese site:

LG18650HG2L is a battery released by LG Chem recently. It’s a big competitor with Sony VTC6. HG2 for a maximum continuous discharge capacity of 20A and has the same capacity as VTC6. Unlike his brother, the LG HG2 Brown, this new version is more advanced and does not lose as much tension as the old LG HG2.

Thanks for the link. Those people stole my picture, the first one, which I took myself as well as added my logo.

I have some LG HG2L and it’s definitely better than the old brown one. Not super scientific test but I have some 18650 lights that can draw way more than 20A and from my experience, most batteries struggle a bit to reach their rated continuous current but this HG2L just sucked up 20A like nothing. In fact, it performs very similarly to my VTC5As. But take my words as a grain of salt since my VTC5As have been used quite a bit so IR most definitely have gone up, although they’re not very old, and my HG2Ls are quite new. I have some VTC6 as well and they usually peak at around 17A even when new with the same light.

EDIT: Whoever owns that Vietnamese shop just updated his/her site with their own picture of the LG HG2L after I confronted them. Even asked me if I’m “happy now?”.

EDIT2: Brilliant, I just realized they copied my description as well.

Vapcell posted the HG2L on July 22, 2019 although the box was dated 2018-03-27. I guess Vapcell just got them in. Seems like these might be a limited run like the Sony 18650 VTC6A that Vapcell was selling that sold out within a few short months. The VTC6A was and still is the best 18650 but unfortunately Vapcell was the only one that had it and in very limited quantities. So if this LG HG2L is good, better get them before they sell out.

SKV89:

… The VTC6A was and still is the …

Whatever.

Murata/Sony @#$% with VTC6's cycle life according to some tests.

SKV89:

To milk the cows.

I hope for it being mass produced, albeit at least in NKON its price is not among the most enticing ones, imho.

Not sure I agree with you. I have been using primarily VTC6 in my flashlights that I need both good output and capacity. I use the VTC6 often for work. I don’t notice any issues after two years of use. I also been using the VTC5D for a long time for my hotrods but have since switched to Molicel P26A, which is slightly superior. According to Mooch’s test results, I don’t see any other 18650 around 3000mah performing better than the VTC6A. I bought the last 2 Vapcell VTC6A and I love them. They tested at 2983 and 2986mah. I do hope the HG2L will come close or even beat the VTC6A but I doubt it.

I inquired with Vapcell to see if they know how the new cell performs and they said, “LG HG2L is almost the same as LG HG2”

On a side note, they might be getting in a small batch of VTC6A

I just did some output testing with the E07 XP-L HI using fully charged cells.

VTC6A 5,790 lumens
VTC5D 5,780 lumens
VTC6 5,300 lumens
Molicel P26A 5,820 lumens
Samsung 20S 5,950 lumens

Out of the bunch, I would choose the VTC6A any day followed by the P26A. I measured the VTC6A with only 150mah less capacity than the VTC6 but better performance throughout the discharge curve. P26A will perform better along the discharge curve but I measured it at 300mah less than the VTC6A.

Side note. The same E07 made 6,600 lumens with the P26A last time I tested but recently I tried putting a NCR18650GA button top in it and crushed the spring. So be very careful what cells you put in your lights. It can permanently deform your springs resulting in much less performance.

It is really amusing to watch the amount of effort and money some of you spend to gain a prawn's hair difference in a measurement. Are you going to some kind of competition to see who among you got it bigger?

SKV89 · 2019-09-07T02:39:21.000Z

It’s part of the hobby to push everything to the limits where possible. Just like people modifying cars trying to squeeze every last bit of horsepower or shave every last ounce of weight.

we sell the HG2L battery，have enough stock

What are your test results? Is it equivalent to a VTC6, or just a plain HG2?

This is the HG2L produced at the end of 2017, similar to the performance of LG HG2 in the same period.

At present, LG HG2 technology continues to improve, capacity and power are improving.

So the performance of LG HG2L is slightly worse than that of LG HG2 in 2019.

Thanks Dennis. Thats what I thought, a LG cell designated for a tool company. Just like the (yellow) LG HE4 was for Bosch cordless tools, with identical performance to the (red) HE2, except that it was supposed to be able to handle heat a little better

So LG HG2L samples from Nkon arrived today. One major difference which I think was not mentioned earlier is that HG2L have bottom vent. I already started some initial tests with older (but not used) HG2 sample running on the next channel of my battery tester. I hope I will post the results this weekend.

Lets see a picture of that bottom vent. Never seen that in an 18650 before

I don’t think that is a vent on the bottom. Vents are on the positive end

Pajda_cz · 2019-09-12T12:39:12.000Z

Yes it is really so called bottom vent, you can read some study about it for example in this document starting from page 43 https://ec.europa.eu/jrc/sites/jrcsh/files/eric-darcy-nasa-lessons-learned-passive-thermal-runaway-propagation-resistant-designs-spacecraft-batteries.pdf

Ah ok. Interesting article. It’s a weakened area on the bottom. Not the primary vent, but if the cell were to build enough pressure to explode, it would separate at that disk instead of splitting the sides. Always wondered what that ring was for I’ve seen on various cells.

Yeh, radial electrolytic caps often have an ‘X’ scored into the bottom in case they blow.

Electrolytic capacitor

An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor. Because of their very thin dielectric oxide layer and enlarged anode surface, electrolytic capacitors have a much higher capacitance-voltage (CV) pr...
