Need some 18650 battery advice thank :(
 

Hey there I just ordered off eBay the Ultrafire C8 Cree XM-L T6 1300lm flashlight for my m4. I was reading online that the blue rechargeable battery's (ultrafire) suck..... http://youtu.be/echfrdLcPTk
And I saw a million different types of brands. Samsung, Panasonic. I have no idea whitch ones to buy and with what amp?? I want the light To be really bright
For airsoft use I will be using it on low.
Also if anyone has experience with it, mine comes with a pressure pad, will I be able to change modes with just the pressure pad?
Thanks guys for all you're help.

Ultrafire's blue ones work for me
I mean, at the price they are (buy them at DX), they di a good job; And I use the same emitter

Now, I'm sure the non-chinese "knockoff" batteries are better; But I had no reasons to hunt for them
