Well, try sanyo ga, kill two liitokalas doing shortcut, a stupid mistake on my part :person_facepalming: , with fresh sanyo drain very fast, start above 7.3 amps and immediately start to go down so this battery is not enough for Feed the modified L6 but it serves as a sample, greetings !!
I fully charged the Liitokala’s, used a thick magnet between the two batteries because they are so short that they do not really push on the springs very hard, and it is much better: 6.6A using a small copper coil with clamp meter with the tail taken off, and 3800 lumen at 30 seconds with the tail in place.
This is with the added R110 in parallel.
Some magnets are coated with a protective layer. Even if it isnt, there may be a little resistance in it. I use solder blobs on my 2 liitokala that I use exclusively in the L6.
The 2 stock R082 resistors create 0.041 ohms.
Adding a R100 drops it to 0.0291
Adding a R110 drops it to 0.0298
So pretty much the same.
I thought the purpose of the short tube was for fitting 2 x 26350 cells. Right? Wrong?
… making for a shorter easier to carry light, though with a reduced run time.
If you look at the L2 reflector base and compare it to the L6 you’ll see a couple major differences. I do believe a narrower, thinner base helps, You will also notice the angled interior base on the L2, a smoother transition going out into the reflector, then the straight angle base of the L6.
With the XHP50 L2 build I just shaved the reflector base paper thin and the hot spot is very tight and clean, with just a faint very narrow ghost ring of a corona.
The XHP35 HD L6 build, I hazed or diffused the base and up the reflector to about 2-2.5mm, the rings are still there ever so faintly, on the WALL, but outside, nothing! At 3+ amps I have no doubt the XHP35HD E4 3C is putting out 3000 Lumen, pretty impressive high out put big beam thrower!
Notice how thick the base still is, even after filing half of it away, you notice it more when it is sitting on the board! It’s good enough for now……
Just noticed a flash deal @ Banggood for the Clear L6 for short term. Cool White is already out of stock ($45), but 5000k, 4000k & 3000k tints are available.
Okay, I borrowed a clamp style ammeter and used a 6” long piece of 10 GA wire to measure at the tail cap. I say “roughly” on the first 2 measurement’s because I had to convert my old multimeter readings to the newer clamp meter readings using math.
The xhp70 with FX-30 driver and protected KeepPower 5200. Turbo/high:
Stock - roughly 5.5 amp
R082 Added - roughly 6.4 amp
Wire Added - 6.6/2.1 amp
Liitokalas with wire added - 8.1/2.8 amp!
I also swapped in a new lower forward voltage xhp50.2 into my light with the wire added to the driver. Turbo/high.
Keeppower - 6.7/2.0 amp
Liitokala - 8.9/2.7 amp
Big jump up with the different batteries. More than I expected. Even high mode was drawing more amps with the Liitokalas.
I’m told that the really big 8.9 amp load I got with the xhp50.2 was due to the wire I added. It makes the driver go direct drive. If I swap back to a R082 or R100 resistor output should drop down a lot and I’ll get better battery life along with less heat buildup.
