Battery graphs and other ideas

[joedirt]

I didn't see this in the forum, but you should really look at some of the highend flashlight enthusiast forums because it is almost identical requirements.

They use the same batteries and the LED modules are now drawing around 1A. In fact, I'm convinced one of these flashlights has all the compact guts to do perfect temperature regulation and handle the range of input voltages.. And hey, they are already the right form factor.

For instance:

Step down constant current driver, High efficiency with dual mode DC-DC regulator (PWM / PFM),working voltage is 2.7V to 8.4V.

Supports three sizes battery, one 18650 Li-ion battery, two pcs CR123A or RCR123A battery.

Anyways, I found this post when looking for information about batteries. 18650, RCR123, CR123 and there are some good graphs showing the batteries over time.

I'm almost positive one of these flashlights could be modded by adding a threaded coupler and the wiring already appears to be there including an on off switch. (snip the red from the emitter and remove it. Done.)

Good find, however, the problem is this people like to spend hundreds of dollars on one flashlight. Trust me, we know about those flashlights and would love to mod them. Personally if it costs more than $25 it is just not worth taking the time.

The trend in the modders forum is more about finding the cheapest that looks the best.
The most expensive flashlight i have seen used in e-cig forum is the Romisen CR-A8 at $15-18.

Any flashlight can be turned into a power source for e-cigs.
