    Test load tips but not laser related

    Guys thank you all for the answers... I finally ordered 2 thermal pads from AliExpress... With both of them I 'll wrap the battery perfectly and with some proper wiring I 'll both draw current and heat the battery at the same time! I think that this trick will work!

    Test load tips but not laser related

    I 've thought the lead-acid for the winter but I also believe that it 's a waste of money having a battery sitting for half a year. What I 've been taught for the machines and tools is that "if something is being used for it 's purpose will last much more than something that will sit at the...

    Test load tips but not laser related

    Hey guys, I have a lithium battery on my motorcycle and when weather gets cold the engine struggling to start... I know that this is a common issue on lithium batteries so I want to find a dummy but relatively heavy load that will be attached for a little time on the battery and will warm it...

    G-Ball Adjustable Lens Adapter - Focus Fixed Lens Laser Diodes

    Bro i read the description... With the Gball lens there is some beam concentration compare to a no lens diode, right? Adding one more lens like 3E for example, with this adapter, is the beam divergence better than a diode with no gball and just a single 3E? That's what i m trying to find out...

    G-Ball Adjustable Lens Adapter - Focus Fixed Lens Laser Diodes

    So what's the exact use of this product? How exactly improves the beam? Is the beam pattern "tighter" than a simple 3E on a non g ball diode? I d love to see a comparison with photos of beam pattern between a simple lens setup vs with this one attached!

    G-Ball Adjustable Lens Adapter - Focus Fixed Lens Laser Diodes

    Could this adapter be used for example with a g8 and a 3E lens on a diode with gballs lens removed? I mean if i screw the G8 on the diode 's copper host thread to maximize the beam concentration as i would do if the G8 was used stand alone, then use the adapter and then a 3E lens, could the...

    Building My First 7w With NUBMM44 V2 need all help I can get!

    I love this compact size bro! Exactly how I wanna build my next host! 2x 18340 batteries i guess?

    Maximize Nubm44 or any diode beam concentration

    Hey guys i m playing for almost a month with my Nubm44 laser but i m annoyed with my beam concentration from the very first moment... Seems like the furthest the beam goes the wider it gets... What kind of optics should i use to maximize the concentration of that beam? Atm i think my lens is...

    New custom host NUBM44 build!

    Finally driver is mounted on the host side wall, with some kryonaut extreme 😂 for ic and some thermal epoxy on the whole driver to stay there... 40+ secs no blinking! I think it stays cool enough now!

    New custom host NUBM44 build!

    I think this is the best solution... I should have thought about it!!! Thanks for your help @Lifetime17

    New custom host NUBM44 build!

    I tried with a 2 part thermal epoxy but i also have to find a way to keep it pushed on the side wall of the host for about 2 hours until it cures... I think i ll try today and i hope it 's gonna work....

    New custom host NUBM44 build!

    Any idea what heatsink should i use for a let's say, duty cycle of 30s max? I think the one i used is far from being good enough for this job! @Shmackitup

    Question about this driver

    Finally i used my Astral superdrive v! I tested the P4000 and i was able to get up to 4.5A... However the modes are a little tricky so i quit!

    New custom host NUBM44 build!

    Hey guys this is my new custom host and a NUBM44 inside! I used my Astral superdrive v inside on full current, about 4.8A and i attached a small heatsink on the ic... I have an issue though: After 6-7s the diode starts blinking... So i wonder if it 's an overheating problem of the driver or my...

    Question about this driver

    So the Turbo mode works with the delay between the switch clicks? I don't mind if i ll have to just double press!

    Question about this driver

    @nmbusa this driver is the only one that had this kind of output current, in normal diameter, I think... So if i want to make this driver go for the max current what should i do to achieve this?

    Question about this driver

    @Shmackitup how exactly can i avoid all the lower settings and go straight to the max 5A? It s the first time i m using drivers with multiple modes... I m using a host with a tailcap switch only.

    Question about this driver

    Hey guys, i just received 3 of these drivers. http://kaidomain.com/P4000-20mm-5A-1-or-2-cell-3V-9V-6-Mode-Buck-Driver-Circuit-Board?search=P4000 I want to use them with NUBM44 but i want to make them work only in the max current... Is it possible to happen?
