I was able to check Lexels review and the battery carrier is 2S2p. So it’s 6 volts (8.4v). With his 30Q cells he measured 15.7 amps on Turbo. This equates to 7.85 amps per battery.
I also found HKJ’s test on the 26f. It will do more than 5.2 amps. He tested it at 7 amps, but the voltage sags pretty low.
So the 26f is not the best choice for such an extreme performance light. IDK what would happen if you tried to go turbo. It might be a reduced output turbo or it might not go into turbo at all. I don’t have enough experience to say what would actually happen. Maybe someone who knows more can speak up.
Thank you again for answering and confirming my suspicions. I have also seen these comparisons of 18650 rechargeable batteries from danish lygte-info.dk. I wonder how the flashlight will behave after step down how many lumens will it be?
Still very much near the beginning of exploring this world of flashlights and li ion batteries.
Though I wouldnt mind learning a thing or 2 about theory and function along the way…my biggest motivation is safety and proper care.
I saw in this thread that battery configuration is 2S2P. How will the cells discharge during use? Is discharge equal among all 4 or will I need to pay extra attention and charge and reuse with any “extra” care?
The light will draw it’s load from the cells equally in theory. When dealing with multi cell lights it’s important that you start with 4 cells of the exact same type. Same brand, model, size, age, number of cycles on them, ect… Then you “marry” them together meaning you always use them as a 4 piece set. Then you should have equal discharge among the cells for a long time. You still want to check each cells voltage before you charge them to make sure they are the same. If so, then they are still good.
I don’t know exactly how dangerous it is tossing in 4 misc cells. Maybe someone can comment on that.
In series worst case is a battery with lower resistance drops below what is safe, 2.5volts or lower, and damage occurs when the battery behind it of a higher voltage begins to charge it up.
The risk is still present when using parallel, but there is more leeway to my understanding.
