:+1: Congratulations! :sunglasses:
I literally shouted out loud in the office when the notification popped up that I could place my order.
Now I canāt wait for it to ship. Iāve been scouting places I can go to take pictures.
Your addiction is more severe than many here.
Oh itās bad. Iāve bought a couple cameras, learned how to use adobe premiere pro, and am even saving-ish for a drone, mainly for flashlight photography because my cell phone camera just wasnāt cutting it anymore.
Samsung 40T confirmed, great cells!

Donāt worry, it will get better and then get worse again. It is never ending cycles. Just focus on all the fun we get from all these gadgets.
That is very good idea to use drone for flashlight beamshots. A lot of learning and work to do, of course money is one main factor too.
removed massive images
Do you know if the boxes will have all that design work or will it be less inconspicuous?
Samsung 40T confirmed, great cells!
Really? I thought with the massive amperage they would use the 30T.
Yeah. Samsung 40Ts at 35A+ is really not sustainable.
30Ts wouldāve been much better.
Yeah. Samsung 40Ts are 35A+ is really not sustainable.
30Ts wouldāve been much better.
Battery packs are 4s2p, 35a cells will be plenty.
BlueSwordM:Yeah. Samsung 40Ts are 35A+ is really not sustainable.

Battery packs are 4s2p, 35a cells will be plenty.
If the leds need 200 amps at 6v, that is 50A per cell.
It looks like the 40T data sheet says it can do 45A continous, but only up to 80Ā°C. So short duration 45A is okay.
Maybe the 40T is fine since max turbo on this light is pretty short and the cells should not overheat in that short period.

Are they not running these LEDs at 12v? If they are running at 6v that is some pretty heavy buck at play considering the battery packs are 16.8v
I actually said that the 35A+ required by the light at full power are not good for the cell at all.
30Ts wouldāve been quite a bit better.
Also, I doubt itās using a buck. Starting with the MS12, 10k+ lumens go out the window in terms of regulation.
They are basically running in direct drive.

I donāt know how they are running them. I used 6v as an example.
200A@6v
400A@3v
100A@12
The batteries see the same 50A each.

If the LEDs are run at 12v, then they only need half the amperage vs. if they are run at 6v. So at 12v, it would only draw 25a per cell

That image says 40T for the R90TS. I assume the MS18 uses the same?
the battery pack is the same afaik

If you go to Banggood,you see that Imalent sells a two head,(MS18+R90TS,plus one battery pack),combo.
MS12 ran at 12v I am sure the 18 will run at 12.

I donāt think you understand parallel vs series when it come to amperage in batteries.
Letās say the flashlight runs at 12v (Iām pretty sure it does since the battery pack runs at this voltage). There are 8 cells in the battery pack wired 4S2P. So 4 in series and then these 4 are wired together in parallel with the other 4 in series.
With 100 amps total, each group of 4 cells handles 50A.
Each of the 4 cells in series is running at 50A in order to produce the 12v.
If you look at things from the point of view as wattage, the light is producing maybe 1200 watts (200A@6v, 400A@3v, 100A@12v all equal 1200 watts). 1200 watts divided by 8 is 150 watts per battery. Each battery is 3v (Iām using 3v, 6v, 12v to keep things simple. Actual voltage will be 4.2v, 8.4v and 16.8v) So if each cell produces 150 watts and itās 3v, Ohms Law (wattage = volts x amps) says the cell has to produce 50 amps.
I hope this makes sense.
(Keep in mind that Iām just estimating the light needs about 1200 watts to produce 100,000 lumen from 18 x 70.2 with maybe 20% losses out the front. I donāt have actual measurements from the light.)
