Trust Fire 3T6 3x cree XML T6

[michaelheit]

Hi
I have ordered a TF 3T6 from aliexpress (just got an email saying delivery time extended until 12/25/12, over 60 days, is that standard with them).
I want to use this as a bike light b/c its floody.
How do I measure how long it will run based on the amp hr and power setting and 2 cell configuration.
The reason I am asking is because I read up on lights first and not on Li ion batterys first.
Now that I have read I am a little nervous.
I only want to run the light for no more then an hour total each day.
any help in figuring things out would be helpful.
I dont want to have a venting with fire episode.
I will pay for panasonic protected and or Lithium manganese

Assuming the batteries are in series:

Amp Hour (battery capacity) / Amp draw = Hours, the amps cancels out. Realistically, the runtime will differ due to the internal battery resistance and so forth.

As for Li-ion batteries, as long as you treat them well and are reasonably careful, you should be fine.
