Technically, the battery shouldn’t matter too much as far as heat generation since this light uses a boost driver. As long as the voltage is high enough, it’s always going to put the same load on the LED.
Of coarse, a bigger battery means the voltage will stay higher for a longer time. Higher drain batteries can also sometimes be better due to less voltage sag.

FT02 vs ODL20C which one is better in overall ?
Lol, I almost bought a 21700 because I didn’t think I received the adapter, but I noticed the tube seemed a bit shallow so I unscrewed it and unexpectedly found it.
I would like to request a code for the FT02. Thank you.
Interested
Interested , thanks 
All replied.
Very interested!
I need an aswer to this as well,please……
Ok, i need a code also,if posible for battery too
How do you answer this? There is no real answer. They both have their advantages and disadvantages. It’s up to you to decide which one you prefer.
Is this still available for group buy? Is there a coupon? Thanks
Still available ?
hello sir, can i get a code please as well?
The title says FT02 (X) XHP35 Hi /XHP50.
Does that mean the FT02 = XHP35-Hi, and there will be another version called FT02(X) that uses XHP50?
I haven’t seen or heard anything about the 50.2 version. I’m starting to think that they’ve decided not to produce it. Maybe the xhp35-HI version did not sell well enough? Who knows. We just have to wait and see what they decide.
Interesting 21700 X
Interested (again) in 21700.
Is there a XHP50.2 version? Did i miss something?
Which would surprise me because IMO I think this is maybe the best thrower out there that is still a managable size, a great compromise!
