At 5A discharge, the Aspire 18350 (HKJ's chart below is from the Vapcell version) starts at 3.7 V, going down from there during drainage of the battery. Assuming that the tailspring in your flashlight build is not bypassed, at 5A the spring alone will already cause more than 0.2 V voltage drop, the last 0.1 V will surely be lost elsewhere in the current path.
Yeah, but with optimized electrical path and a CC FET driver you will have the maximum output for quite a while.
Run it at 4 - 4.5 A and it will be longer with probably not much less output.
Is there a test of this LED on the forum yet?
Didn’t know (or remember) the Aspires sagged that much though.
With cheap springs you can apparently get away with it.
It looks like it starts at 3.7, but at the beginning it is close to 4.2 like all other batteries.
The surge current happens when the circuit is first closed, and this initial spike in current is what will blow an LED in the first few milliseconds.
This could be due to smoothing of the graph though, i was told the drop is instantly when i asked about the same phenomenon.
A large enough capacitor over the driver input could solve such problems though.
Depends on cooling.
The Driver had his black flat running at 4.5A in his xcalibur, and he had some graph showing how the output drops to 75% after a few seconds or minutes.
I got output increases to about 6 amps on my black flat because I was cooling it with a fan cooled CPU heatsink and liquid metal.
The CSLNM1.TG is basically just a better black flat as far as we know, so I would assume it can also do 6A or even more with appropriate cooling.
