I wasn’t able to check last night, but I will definitely check today when I get home. As for batteries, I use Liitokala and Shockli. Here are tests of the cells:
Ok, I checked the switch board and here are the measurements: thickness = 1.3mm, diameter 20.2mm . They are the same ones that Simon used to carry on his Convoy store with HGJ stamped on it. The host comes with the high amp forward switch that Simon sells on his store as well:
I don’t have any tools to measure the switch hole threads but I posted pics below. I’m not sure if that even helps. Let me know if you have any other questions about the tailswitch.
I have 34mm MCPCBs for 6x 3535 and 4040 LEDs that are compatible with ANNA optics and Convoy C8. I will offer assembled PCBs with LEDs I currently have in stock, LH351D 4000K 90CRI and Luxeon V 4000K 70CRI.I need to do basic tests and build few "demo" lights to see if everything is ok. I will have spacers too, but it's summer vacation season so there is little delay.
After looking a little bit more about those high drain 26650 cells, I 'm little bit disappointed they don't outperform 21700 30T, they actually have higher IR than 30T.
Well they are Chinese cells. If Samsung made them, they would be better. Also they contain much more total energy. The 30Ts are very specialized, they have a very low energy density.
Looking into buying the LD-B4HV driver soon,probably in the next month or so.
Having 3S input and using a 6V LED (XHP70.2) won’t be an issue, right?
.
Also, is there any chance of pushing more current through the driver past 12A? It will be well heatsinked of course, not like in a regular flashlight host.
I’m willing to pay significantly more than the 12e base cost if I can get something like 14 or 16 amps or even more.
LD-B4HV is linear driver,in theory it would work with 3S and XHP70.2,but in practice power loss/dissipation would be immense, basically energy from one battery is wasted.
One solution is to use dummy cell, so that you have 2S, other solution is to use LiFePO4 cells.
LD-x4 can be modified for different currents,up to 30A shouldn't be a problem, if I remember correctly, few guys used LD-2/3 up to 35Amps.
