Fandyfire Queen Battery Drain

.15amps is definitely a lot. I would return that immediately, both because of the batteries getting drained and think about it: that .15 amps has to go somewhere and is probably heating up/breaking some part of the board.

Exactly. It seems a combination of poor engineering/design and bad manufacturing. What are the odds that I get two malfunctioning Queens? HOW2 also has a bad Rook and slightly bad Queen.

I know DX doesn’t allow bad reviews but there should be more complaints on the net. There has to be many Queens and Rooks sold.

4.2 to 4.07 is 1.17?

The 4.07 is probably a typo.

Here is what Black shawdow say's:

"The standby current of Rook and Queen are similar, not more than 50MA"

So long does a fully charged battery last for?

Well, considering a 14500 or 16340 have only, on average, 600-700mA capacity, that gives only 12-14 hours of standby time for each cell. 3 of them stretches it to 36-42 hours before it drains the cells dry.

Now you tell me, does less than 2 days sound like acceptable standby time on a light you cannot lockout? It sure isn't to me. As much as I absolutely love Black Shadow's products, they really screwed the pooch on the Rook and Queen, Hopefully version 2 of each will have lockout on them.

I love the design and no they should have anodised the threads.

So you really don’t think that anything is wrong with the horrible standby time on this light? How could it possibly hurt the light if they simply built in thread lockout by making it like the King that they wanted to emulate in the first place?

JohnnyMac I mean yes it's totally wrong

Ahh…gotcha! Heheheh…we almost always agree on things and I was shocked to think you thought what I thought you had said. LOL.

Cheers! :beer:

Stop messing with me. I have all three lights now and the is still the best. That's why the Darth got a clicky.

Crap!!!.. I’m screwed!! I have 1 Queen and 2 Rooks coming from Fasttech. You’ve just put the proverbial nail in the coffin for any potential hope of getting a decent product.

I almost wish I wasn’t so damn curious!

My new Rook has a .02A parasitic drain. After 18hr, the batteries were drained .07v. That means fresh batteries would only last around 14days. That sucks…

All this talk got me concerned, so I just did a quick test of my FandyFire Queen (new from fasttech.com).

My 3 AW 16340 protected cells were charged at 4.12 volts each, installed in my Queen with the power left off (there’s no lockout) and I placed it on the shelf.

75 mins. later I tested all 3 cells and they were still at 4.12 volts. Whew. Nothing weird.

Amazing, how did you get so lucky.

My first Queen from dx was DOA. Second has severe drain. First Rook from Fasttech has drain issues. I can’t believe my bad luck.

After doing the initial measurement @ 18hrs, I put the batteries back in for another 12hrs and measured again. There was no additional drain; it stayed at 1.26v. I measured it again 12hrs later and there was no additional drain. This is very strange.

I’m wondering if the drain is somehow affected by how tight the head is screwed on. After the initial measurement, I left the head a 2mm twist from fully tight. I know the threads are not anodized so there is no quarter twist lockout feature. The flashlight fully works when barely screwed on. So, the circuit is complete and and the drain should still be there.

I’ve fully tightened the head now and will measure in the morning. Could I have gotten lucky and is the parasitic drain resolved?

Received Queen from Fasttech today and wtf! Only 3 modes!? Not that I cried for the SOS, but the medium would have been nice to have… :~
Seems that they have put the Rook driver in this one as it seems to only have these 3 modes… Weird!

Remind me not to mention to my guy friends that I have been “playing with my Fandyfire Queen”

The Queen has only has 3 modes High - Low and Strobe.

Well, not according to their and every other webpage… :frowning:
