THESE ARE THE ONLY 18350 AVAILABLE ON FASTTECH

They should be fine for single cell lights, the capacity is over rated but that is expected.

Shaquille, I have no idea. That is the problem with xxxxfire batteries. I would personally recommend some AW or Efest ones, those you know are good quality.

I'm not really a fan of Ultrafire batteries, but these seem to be OK:

I have four of these cells for my laser, and they’ve been performing quite well.

They’ve been handing around 1.2A current draw in series of two cells and of course, I need to make sure they’re well balanced and don’t go below 3.6V for me.

Cheers!

I also have four of these since Nov 2011, not really pushing them too hard, use them in Romisen RC-K4 (2 cells) & L2M with 1.05A driver.

Last year end I tested discharge capacity with my iMax B6, 0.6A load to 3V cutoff, gave me an average of 831mA.

Given that they’re not protected cells, I’ll top them off once every half month of light usage.
