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.
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.
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?
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.
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.
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.
But seriously, nothing new, the only data / value that changes in this datasheet compared to that of Brown HG2 is the Voltage Cut-Off operation, it goes from 2.50 Volts to 2.00 Volts, which explains and confirms the rumors and the reports of the sites which indicated a better management of the current during important sag of voltage.
After initial tests I can say that there is no significant difference. In fact older “brown” LG Chem HG2 cell sample, manufactured in Dec 2016 seems to be slightly better. I added one sample of HG2L to my cycle life test, but it will take some time to get results.
