Hanklights with SBT90.2?

[YBF650]

@dmenezes

And good idea re: being able to use 18650s: I even have a 18650-battery-to-21700-flashlight plastic adapter, I just hope it doesn’t heat-insulate the battery too much and lead it to baking itself inside the light. And I understand I will need to buy high-current 18650s, as my LG MJ1s top at 10A max – and I hear the SBT90.2 can drain up to 25A on turbo – so I might end up spending less and getting better capacities by buying a few 21700s anyway.

If you decide to go with an 18650, get the newer Molicel P30B, otherwise the best suited 21700 is the P45B. My hottest 18650 is the slightly older P28A, but I’ll be testing the max intensity between both lights a bit later today.

If you want to drive the lights as hard as possible without any regard to capacity, the Lishen LR2170LH is the best cell available, but it is only sold by Neal as the LR2170HP and by Vapcell as a special order item. It was those LR2170LH cells that allowed my 3x21D to hit 1Mcd, though it was very close with P45B at 985kcd.
It might be possible for the 3x21D to reach 1Mcd with P45B by doing some hotrodding to the host, most importantly replacing the tailcap spring holder with a copper plate with BeCu (or bypassed) springs.

Does Hank sell the DM11 driver all by itself, or would it be necessary to cannibalize a DM11 in order to get one?

Yes, but any of Hank’s linear+FET drivers should work fine. You can buy them as an email request, iirc it was $12 for the linear+fet drivers. I specifically chose the DM11 driver because of the larger board, it isn’t as tightly packed with tiny SMD components and only had them on one side.
You want to request a large size switch PCB to go along with it, K1 or K9.3 sized.

@dmenezes

Have you posted pics or whatever from that Hankonvoy (Hank brains on a body by Convoy ) anywhere?

So far I’ve done 3 (M21C-U, H1, 3x21D), but I don’t think I’ve posted the build for the 3x21D on here yet. It was kind of tricky to put together but that was mostly because I had to figure out where each thing went.
Replicating it shouldn’t be too difficult especially if you have access to a hot air rework station, I just had a soldering iron, tweezers and a microscope (optional but convenient).

On that same vein, what about the Convoy 4x18C? IIt seems to have even better sustained performance than the 3x21D (sources for these graphs: 4x18C, 3x21D); the 3x21D has more reach at 1816m vs the 4x18c at 1162m, but I wonder if that’s practical (I don’t think my eyes would be able to discern anything even at 1000m without a telescope/binoculars) and there’s value for me in staying with my LG MJ1s (as 4 of them would be more than capable to supply the 25A the SBT90.2 needs).

Regarding the 4x18A, IIRC the driver pocket is the same so the mod should also fit. I would still use Molicels in it though, as the modified FET driver will draw as much current as it is given, and the SBT90 will still keep increasing in brightness past 30A.
The regulation should be the same as any linear+FET anduril light except that it uses the FETs on the original driver to provide an optimized current path, so the maximum brightness will be a lot more than it normally would be. I haven’t been able to measure it but I would put the ballpark at more than 5000lm.
