could someone help me.
I have the astrolux ft03, I’m using a sofirn 26650 mah, 25a, discharge battery. My question is, this battery can use all the power of the flashlight?
You’re wrong though. 25A rating doesn’t mean it’ll hold a high voltage on a high amp load. You’d need to see a graph to know that. I have a Sofirn 26650 and it’s no where near as good as a high drain 21700, especially for the new FT03 at 9300 lumens. Even the XHP50.2 version performs 500 lumens higher with a 40T than Sofirn’s 26650
To the OP, I unfortunately do not know where you are able to find authentic quality cells in Brazil (or a retailer that ships to Brazil), but I only use molicel p42a 21700 or Samsung 40t batteries in my high output/ high amperage lights. I have not seen any reviews of the Astrolux batteries you referenced but my assumption is that of course Astrolux is not making their own batteries, and they may be rewrapping a Lishen or possibly lesser quality cell. Given the price I doubt it is higher quality. But Lishen is good, and I believe sofirn uses Lishen batteries too.
but my point is that you would serve yourself much better using a Samsung, molicel, Or Murata (Sony) 21700 instead of a rewrapped "lower power" cell with a light like the ft03 or especially ft03s. Now, if you have the sft40 version, then the Astrolux cell will be fine, because even if it can hold 10-12amps CDR, you will have all the power you need.
for my sft40 ft03 I ran a 10amp 5000mah Lishen 21700 and it was great.
agreed. I was merely guessing, but they could be using any cell under that wrapping. And that could be a bad thing. I would buy Samsung, molicel, Panasonic, Sony murata, or even Vapcell if you can.
I dont have the money to waste, but I almost want to just grab some (of the Astrolux cells) and cut the wrapper off to see what they really are. And then we can all know.
Yea, I don't know if it's a guarantee you will see the original mfg wrapper underneath though. Usually they probably do leave it though. Maybe I will haha
