Thanks, gents. Where do they sell the referenced Vapcells?
Nice one! Didn’t remember that!
Thanks for the vendor info. These Vapcells would be almost twice (with shipping & tax) what the Xtars would cost, and the Xtars would ship from the U.S., where I am. Would they be worth the big premium?
Prizes are in favour of the Xtar, of course.
The Vapcell:
- has USB-Charing (which can be good in case you don’t have a charger at hand and wanna travel, but can, eventually but only in rare cases, be bad in case there is some issue with the charging circuit).
- has more capacity (theoretical 950mAh, more real around 880mAh - 900mAh) than the Xtar (800mAh) - in can be relevant in case you are using the lowest modes, in which you will have more “juice” to feed the light.
- has maximum continuous discharge current is 2000mA against 1600mA of the Xtar (if I understand well, this means that if a flashlight pulls more Amps, the Vapcell will give a marginal superio limit, although not much higher )
- is 3.4Wh and Xtar is 2.96Wh
- is 50.3mm*14.1mm and Xtar is 50.5mm*14.3mm
Also, the Vapcell has been tested by HKJ but no testing data from the Xtar… Decisions decisions. 
Excellent points. Thanks, MascaratumB. Yes, indeed, a lot to consider!

The Keeppower 1000mah is excellent. I bought mine from Illumn and they preform amazingly, with some of the longest runtimes from any 14500. They make an 1100mah version, but for only 100mah more you sacrifice 2A of discharge.
Gentlemen, thanks for the recommendations but I think the problem is the length. I’m really trying to keep it under 51 mm and the Orbtronic is 55 mm and the Keeppowers are around 52 mm.
Regarding protected 14500 batteries — it’s usually difficult to find out at what discharge current, the protection circuit will trip. (unless it’s tested & reviewed by HKJ, which will then indicate the current when the battery gets cut off)…
I think many protected 14500 batteries trip at around somewhere 2.5-3 Amps. This may trip when used in certain 14500 flashlights that can draw around 4 Amps or a bit more (eg. Klarus XT1A, GT Micro or BLF X5).
I understand Vapcell allows option to add protection circuit to their 14500 batteries (some added cost), but I wonder what is the ‘trip’ overdischarge current for their protection circuit board…
Truly frustrating. Eg: the unmarked cell that came with my GT MICRO (Osram) from Lumintop runs fine in all my 14500 lights. However, the Lumintop branded (wrapped) cell (920 mAh) that came with my AA TOOL 2.0 runs fine in the Tool, but trips immediately upon turbo activation in the GT. Strangely enough, I bought a couple Nitecore NL1475R’s (750 mAh), and they run turbo in the GT without issue. Seems like it’s a crapshoot.
Wellp, the ToolAA’s only rated for 650 lemons (just goggled it), so it ain’t a screamer, and LT probably shipped a lower-current cell.
The ’micro is rated for 1000 lemons, so probably needs a higher-rated cell.
Point being, they probably shipped the “appropriate” cell for the light.
Not so strange since the protection circuits are added by either the seller or middleman. One never knows what they’re getting even if the cell itself is the same.
Totally get that. I’m just thinking out loud it would be
beneficial for the end user to have some relevant specs published along with the product, in order to acquire the appropriate power source a la carte, so to speak.
I have the reverse question - I have a few Keeppower 14500 protected cells and what do they actually fit? Didn’t work with my Convoy T2 or T3, Really hard to screw the cap on my Sofirn SP10 Pro.
