Anyone owns the XinTD X3 from Wallbuys/Banggood?

Definitely do! I got this instead so I could attack Tigers in the Jungle, or maybe crackheads too!

I think you mean the spiky bezel, not the sharp edges that left by poor machining.

Yes, I really don't understand people like poor machining that can even cut your skin.. that's what I meant by No sharp edges=poor machining.

The battery carrier from ios is far better imo :)

Yes I did actually notice that, but considering the significant price difference I ended up ordered with Banggood anyway lol.

I paid 34 for one with T6 4C.... a good price I would say..

Don't care much for the battery carrier.

i guess the xintd x3 that wallbuys sells should be the same banggood sells? (hard to know, but flimsy 3AA carrier, 3/5-modes, no moonlight mode should apply to both?)
i ordered 2 from wallbuys group buy a couple of months ago (i have received one, the other one seems to be lost in china post since 17 november…)
i have tried the one i’ve received, and when i use 3x GP Recyko batteries, and use high, after a while the flashlight ramps up and down, is that a low voltage warning? it happened when the batteries where quite fresh though, and IIRC 4.02 V resting voltage over the battery carrier.
I am thinking about gifting one of the flashlights as it should be great for non li-ion people, but i’m unsure if i have a defective flashlight, or if it can’t be used on high with nimh’s?

I notice FT also sell the same one with Banggood. at least the same battery carrier.
can anybody post a little bit update after couple months usage of X3 from Banggood one?

I’m considering this one over Starry Light…

thanks…

I’ve bought X3 from BG… What would you like to know?

Quality wise…it’s excellent! Threads were a bit dry on arrival but I lubed them and modded this weekend(replaced driver for Qlite with added 4x7135 380mA and changed led to T5-5A3) and I couldn’t be happier.

I have just added a little information in the OP, hope that helps a bit. :slight_smile:

Hey thanks for the update. Does the battery carrier limiting the current on eneloop?
as for the FT nanjg driver you pointed out, I have using quite a lot of it. perform like it should be although it’s not like Qlite on IOS one.

The total current draw with Nimh batteries on high is about 2.1A and this is also measured by other forum members. The AA batteries are in series so 2.1/3=0.7A current drawn from each battery. I’ve never measured the resistance of the battery carrier though but I think it won’t be an issue to limit just 0.7A current draw from each AA battery.
2.1A is drawn from each battery.

I have purchased some of these cheaper Nanjg drivers from FT too and yes they still can perform like the other 105C driver in terms of current draw. Now if you know how to re-programme these drivers using the Nlite developed by Dr.Jones then you can programme it into whatever modes you like with higher PWM frequency.

If the batteries are in series 2,1A is drawn from each battery. (if the batteries are parallell they would be delivering 0,7A, but then you would have a voltage of 1,2V instead of 3,6V…)

i did a basic test some weeks ago with my X3 from wallbuys. I used 3 quite fresh GP recyko’s and measured 4,02V resting voltage at the battery carrier. Then i used 2 DMM, one measuring current (i think it was about 2,8A on high) and one measuring voltage under load.
-It didn’t take long for the 3 batteries in series to fall to 3,2V under load.
-So i guess that’s why i have been having problems with this flashlight when running it on high with AA’s. After a while on high it starts ramping up and down, and i’ve been wondering if that’s a low voltage warning.
-Maybe recyko’s don’t keep up their voltage under load as good as they would have needed to be used in this flashlight.

i’m going to gift this flashlight, so i’m thinking about changing driver to something easier on the batteries, maybe 1400 mA could be good enough for this flashlight in the hands of a non-flashaholic using it on AA batteries.

I stand corrected.!

Thanks OscarM

no, when you add them in series the current drawn from each battery is the same, but the voltage adds up.
so for the total of 3 batteries @ 3,6V and 2,8A every battery needs to deliver 2,8A and 1,2V

power = 3,6V * 2,8A => 10,08W
each battery provides a third of that:
1,2V * 2,8A = 3,36W

Hopefully this helps

I stand corrected.!

Thanks OscarM

Hi OscarM, I think what you mean are on the output side? Let’s say a light with three LED wired in series, the current going through them is the same but the voltage is added up.

EDIT: Okay I am not an electronic guy so I don’t want to put it into calculations in case my math errors may confuse some people. So I just mention an example:

My friend has a Skyray STL-V2, as we all know it has a single XM-L powered by 2*18650 in series. With freshly charged batteries we measured about 1.4A and 8.2V at the tail, but actually the LED receives about 3.5V and 2.8A of current.

hey, cool down and think a little?
yes, we’re talking about current draw, and i included voltage and power as well.
noone has talked about capacity… (power (W) and capacity (mAh) is not the same thing)

-if you have 3 nimh AA batteries in series, you get (nominal) 3,6 V. agree?
-if those 3 batteries in series are in a flashlight that pulls 2,8A we have 3,6V and 2,8A from the batteries. agree?
-the power from the batteries is 3,6*2,8 = 10,08 W. agree?
-for 3 batteries to reach 10,08W, each battery need to deliver a third of the total power: 10,08/3 = 3,36W. agree?
-each battery has a voltage of 1,2V nominal, and to get the current when we know the power and the voltage we take divide the power by the voltage: 3,36/1,2 = 2,8.

So in series each battery has the same current drawn as the total current draw. the benefit of adding batteries in series is that you get a higher voltage.

Guys, OscarM is correct as in the formula. reference here.
So, if one buy this light merely to use with AA only to obtain maximum output (and also run time), do you guys as users recommend it?
