This is one of the new high capacity 21700 cells.

The two cells are very well matches, but they do not like high current (I forget thermosensor on one of them, it survived, but must have been hot).


This is a good quality battery and with high capacity.

Thank you so much for reviewing this cell - it is very high on my to-buy list and I can’t wait to get my hands on it!

Thanks for the test! Seems good for any of the 21700 flashlights I have. Definitely not a high drain cell.

Does someone make a genuine 20amp/5000 mah cell or is this as close as we get?

Thanks HKJ!

Thanks for the review! :+1:

Yes ….

The E-One Moli

Molicel INR 21700 5000mAh 20A
The model is
50M or M50
I do not remember

I do not know when will be on the market ….

An other battery ….

Panasonic (Sanyo) NCR 21700 A 5000mAh 15A .
You will find this battery as
Vapcell 5000 15A (purple)

Those sound perfect. I will shop around. Thank you.

Molicel not yet reach 5000mah, highest only Molicel P42A 4200mah rated 20A.

Its LG M50 21700 5000mAH and its was rated 10A.

No my friend .
I am talking about Molicel …. Not LG ….
It is a new battery from Moli , with 5000mAh and 20Amps.

At last …
I find it …
It is M50A

I think is on the market , but I do not find ….


M50A Samples are not available for the time being.

M50A is flat top,more users will like it :crown:

Wow! When this coming? So there are molicel succeding 5000mah rated 20A…Thank for the link shadockan…I probably wouldn’t had know this…

But why the name M50A where so close to M50 LG…when they always came with letter P, such P42A, P28A…

Anyway, will try to find out where this was sold…

Or you can get the Lishen LR2170SF, which Mooch says is the best high capacity 21700 at the momoment beating LG M50 and Samsung 50E. I bought a bunch of them and they measure about 150 to 200 mah less than the M50 and 50E but outputs much brighter on my E07 compared with the M50 and 50E. Its my fav high capacity 21700. I read that Lishen has another version of this cell I think it is called LR2170SC that has higher than 5000mah capacity. Im really looking forward to these upcoming cells from Molicel and Lishen.

SKV89 very good battery the Lishen 4550.
But here we are talking about a different type of battery …
Lishen SF is NMC, while the
Samy 50E
LG M50
are NCA batteries.
Lishen SF is capable of 20A, while Samy - LG for 10A.
Lishen SF will compare it to the
Samy 40T
Moli P42A.

Molicel called the battery … M … because it belongs to batteries of *M*edium power capacity.
The batteries
*P*26A - *P*28A,
belonging to *P*ower Batteries .

such a good test, really appreciate the inside information. I recently purchased a 21700 flashlight and can’t wait to buy the right cell.

Another battery that is superior TODAY up to 15A compared to Lishen SF is the following …

Panasonic (Sanyo) NCR 21700 A 5000mAh 15A.
You will find this battery as
Vapcell 5000 15A (purple).
Not Vapcell 10A …….
At 20A something did not work correctly on HKJ’s measurements and did not give the right result (if I remember correctly)

This thread is a great resource for finding some high drain 21700. Both Convoy and Sofirn have new torches that use this size cell. I am glad the community made this info available. Thank you for all the contributions.

Any one try this wonder how it perform https://www.aliexpress.com/store/product/LiitoKala-21700-4800-5000mA-Li-ion-Battery-3-7V-Discharger-35A-Power-battery-Electronic-cigarette-battery/1823237_32999816891.html?spm=2114.12010612.8148356.1.7aae5e0dMvj741

Not sure what NMC and NCA mean, but if the Lishen LR2170SF 4550mah (I measured at 4,7xx - 4,8xx mah) measures at a mere 150 - 200mah less than the Samsung 50E and LG M50 (I measured both at 4,9xx mah) but is actually in a higher performance class of the likes of 40T and P42A, then that makes the Lishen even more amazing! I replaced my 48G, 50E and M50 with the Lishens in my mid power 21700 lights because I know it will maintain a higher output level throughout the entire discharge curve and the price is good.

I don’t like the Panasonic (Sanyo) NCR21700 5000mah battery because of the recessed top, it will not work in my charger. I bought both the Vapcell recessed top version and button top version. The button top version soldered on by Vapcell adds so much resistance that it performs significantly worst than even the 48G. Ouch! Therefore I think the best high capacity on the market right now is the Lishen LR2170SF until the Molicel M50 or Lishen LR2170SC becomes available. I think Vapcell said they will be trying to source both of these, but I doubt they will be able to anytime soon so if anyone is in the market to buy high capacity 21700 cells, don’t wait on it.

Sadly, Lishen LR2170SC can only shipped to certain countries supported by 18650battarystore.com. Anyone knows any other sites that sell it? Is not even in aliexpress.
