I am looking at buying my first 21700s, i like capacity but also want the highest amperage output.
I am choosing between LG INR21700M50T 5000mAh and Samsung INR2170050E 5000mAh.
Which one should i go for and why?
Less voltage sag and longevity (number of cycles) are considerations and of course i want the 5000mAh capacity. I would be using my 4.2V chargers (i think they both charge to 4.2V).

Samsung 40T or Molicel m42 if you are worried about sag. Samsung 50E stops working on High on my Acebeam ec65 after 3.7v. aforementioned should be better for performance.
Has HJK tested both of the cells in question? I check there when making decisions like this

I have 5 of the Samsung 50E 21700 batteries and they work well. The LG has a maximum continuous discharging current of 7.275 amps (according to Illum) vs 9.8 for Samsung. For the same price, it seems the 50Es are better.
There’s also the LG 50LT which Illum states: the LT model has twice the rated cycle life (1000 cycles) vs the standard M50T.
On HKJ’s charts those two are virtually identical at every amperage tested. I’d buy whichever is cheaper or has a wrap color you prefer.
If you can find the Samsung 50G, that is a significant improvement in voltage sag while keeping the capacity, actually rivaling the 40T. I’ve not yet seen them for sale down here but would love to pick some up.
I have several of the 50E and no complaints at all. After accumulating a bunch of the Sofirn 4000mAh, which are very decent, the Samsung is certainly a little better in both areas. If voltage sag is your main concern then the 40T 4000mAh is a better choice for anything over 3A or so, and if running above 5A then the capacity/run time might just be a washout between the 40T and the 50E/M50T.
