For the record, I used to have this light and protected cells worked fine. The springs are very long, so when you put the cell in it sticks out of the body tube a lot, but the springs compress a lot too. I wouldn’t use it with unprotected cells. No LVP.

The need for button top cells is generally rooted in some sort of piss poor device design. For example, a flashlight lacking reverse polarity protection.

The button top thing is not part of a cell's prime condition, they're flat tops by design.

As others have said, the NCR18650GA is great, but its effective minimum capacity is not “3500mAh”. It is more like ≈3250mAh. Check its review at lygte-info.dk.

You pay a premium for the unrealistically rated 3500mAh cells (even the best in class Samsung 35E can only do a minimum of 3300mAh down to 2.8V at ≈0.2C), while they barely deliver any extra performance over more regular and cost effective cells like the NCR18650B or LG F1L. And there are even cheaper cells with better performance/price ratios. This isn't meant to discourage anyone, of course. Go pay your premium if so you choose.

The human mind, and its programming, is at the forefront of a particular battle of The Light vs evil dark forces. Nearly every human being on this beautiful planet “Earth” has some sort of negative mind programming in its mind. And you better take care of your mind programming, or someone else will in this wicked world.

Please avoid fully quoting lenghty posts, namely with nested quotes. Trim quotes down to the essential. Helps with neatness and legibility. Thanks.
