and as far as I know there is a serious risk of very unpleasant explosions (!!!) if you happen to have a bad cell in that cluster of lithiums, at least that's what some guys with a lot of knowledge told me. so ... this beast is certainly not for me, even if it was available ... one problem solved, I do not drool any more over this one.
As I understand it, you are fine provided all of the batteries used are in good working order and equal states of discharge. It's when a depleted or bunk battery is included with other good cells that problems may arise. I suspect that due to liability issues, manufacturers are quiet about the 123 cells and the cautions must be carefully written.
When KenRad brought out their PSL35 HID, they planned on selling it with both a battery eliminator and a 123 cassette which I believe holds 3 banks of 5 123's in series. When KenRad went to source cells from the battery manufacturers to provide with the light, they were told of the dangers of mixed cells and were warned not to proceed. If I'm not mistaken, I believe the battery manufacturers either refused to sell the batteries or the warning was significant to the extent that KenRad is not offering the 123 cell cassette. There seems to be some real taboos surrounding the use of both lithium and Li-Ion cells in applications where they are placed in series for higher voltage outputs. I have heard enough to have a vague unease or apprehension when it comes to large gangs of lithium cells. At the very least, I have respect for the clustered battery paks and will only use brand new cells when loading them. The Li-Ions scare me more than the 123's but caution is warranted in all cases, I think.
I can understand where a depleted rechargeable cell in a series would essentially be getting charged at a very dangerous overvoltage condition. I don't understand the chemistry to have a feel for what happens when the s$$t hits the fan; especially with the 123 cells.
It would be nice if some real facts were laid out for us to understand.
thanx Don for helping me out and clarifying the facts. I am sure everyone appreciates when the pro's speak up ... [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]
Thanks for the vote of confidence but I am no pro here. The topic of lithium safety is off topic for this thread and I don't want to shed any bad light (no pun) on the Beast. From my experience with SF, they will not be providing any product if there is concern for safety of use.
I noticed in SureFire's ad in the October 2003 issue of Popular Science, a HID flashlight named "The Beast" is mentioned. Is this light going to be available to consumers, or is it strictly a military item? If it is, why mention it in a consumer magazine?
Response from SureFire:
Thank you for the inquiry and continued support of SureFire products. The Beast will be available to all consumers when it becomes available.
Not sold buy SureFire to anyone as far as I know. the HellFire was a NiCad battery body that was HUGE
Beasts from what I can get are a generic term of SureFire's experiments with Handheld HID flashlights based around several types of HID bulb and even more ballasts. The battery bodies range in size and chemistry too.
There is no more HellFire and there hasn't been since SHOT 2002. (at least that's the impression I get)

i would want one in HA black or the gun meatel +purrs like a kitten+ how do you think it compares to the photon king and does that mean if you join the millitary then you get to use one.

The Beast and the PhotonKing are two different kind of lights with 100% different technology behind it. While the Photon King is a one-of-a-kind and not an official SureFire product using solid state lightening with a special reflector the "Beast" uses a HID lamp with a special ballast to provide enough juice for starting that lamp. Thus the characteristics of both lights are very different. Whatever lumenreading the PhotonKing has, it would not be interesting when seeing the Beast, nevertheless for its size it is a hell lot of light. Remember that I have never handled the PhotonKing and only tried out the Beast for a couple of minutes!
Regarding your "joining the military", I guess this is not standard equipment to any soldier so "just joining" might not be enough.
