Even have the new 18650 cells with a built in charger via mini USB at the positive end of the cell on the way.
That’s right, plug a charging cable into the cell itself and charge it from a back-up power supply or the USB port on the computer or car. No bulky charger to keep up with.
High drain cells are not neccessary (max. 2.2 amps) and the TN42 is fully regulated. It doesn’t behave like the K70 which has a stepdown first and later continuosly gets darker and darker. I used regular high capacity protected cells in my runtime test:
2 series cells for 8.4V at 2.2A each cell is still doing 2.2A. [Edit: add another 8.4V battery in parallel and the amperage stays the same, capacity doubles, so all 4 cells should be seeing that 2.2A and with say an Efest 3500mAh there should be 7000mAh capicity, is that right? I tend to not be sure how this all works, since I’m so forgetful.]
So any cell can do that. Panasonic B’s come to mind, or the new Efest metallic purple 3500mAh.
Dangit! I just got 2 of those and 2 3000’s! Ugh, why wasn’t I thinking? Oh, yeah, I also just got 8 Samsung 30Q’s. Nevermind. Still though, 4 3500mAh would be max run time possible, might have to snag another set and get 4 this time as I put the spare cell circuitry for my new TM03 onto one of those 3500’s.
I don’t guess y’all opened the sample up to see what the driver layout looks like by any chance?
Seems like they’re probably running the XHP-35 at around 1.8A, maybe 1.5. I’ve got one running 3.13A and making 2986 lumens in a Convoy L2 off of Neven’s LD2 with modifications. Wondering if a bit of a bump might be viable for this one. Hmmmm…… dang light hasn’t even shipped and I’m already planning it’s demise. lol
Edit: I DID notice that in y’all’s measurements it hit some 647Kcd, 20’ shy of a mile. Impressive!
I can tell you that the TN42 on Turbo (constant brightness without stepdown like the K70) after 10 minutes running is about 50’ degrees. To hot to hold.
What temperature would it be if you run the XHP35 higher? I think Thrunite made it this way because of safety purposes.
