The folder of full manuals that SBSLIDER posted a link to will give you all the ins and outs.

If you just want a simple cheatsheet, one of the files in the DIY link (see my sig) has a cheatsheet you can print and keep rolled up between the batteries. Thumbs Up

When they have more ready to sell, the next folks on the list will start getting notifications.

If you’re on the list, and you have your PMs enabled, the only other thing you need is patience.

Thank you for leaving your post, as this will indeed help other people.

You can’t see these stickers if they are transparent and cover the entire metal surface as there’s no obvious edge between the sticker and the wrapper. Every seller should use black or some other color.

Using a #2 pencil or thin straw is a great support for rolling up the cheat sheet small enough to fit in the space between the cells. I tried wrapping around a cell, but there is not enough space, which is probably a good thing.

Just opened mine. Keep in mine I’m a complete flashlight noob. Has anyone made any YouTube instructions on how to use this and all the different many features? For me, it would be easier to follow then the written manual.

Second. It came completely dead which I thought it would have had a little juice. No big deal. So I read in the manual to plug it in to charge. The manual says the button should be red when charging and green once charged. So I plug it in and it is green, not red (meaning its charged?). When I take it off the charger, it won’t turn on, so it can’t be charged. I can turn it on only while plugged into the charger, and the green light is on… (I just opened and so it has not been on the charger long)
Thoughts?

Edit: I’m in idiot. There were stickies on the batteries so they would not make contact. Now charging normally

I’ll leave my “problem” instead of deleting it incase anyone else is a newbie like me and does not know.

On my first point, i think a YouTube complete instructional would be really, really helpful for someone new to this like me

Good idea & point. Thumbs Up I will try to do a full instructional video this weekend coming on the LT1, its Andruil programming features, operations, features, etc.

Thanks! I’ll be looking forward to it! Ps, I don’t even know what andruil is. I’m guessing it’s part of the ui. Anyway, I’ll be looking for a I instructional. Thanks so much!

I will explain in detail in the coming video. Big Smile

one last question about ramping mode:

It there a way to set the ceiling to 100% and still be able to activate 140% with a double click?
In other words: Is there a turbo mode or was this disabled for the LT-1?


You can try to enable all the 7135’s and configure the ceiling with 130/150. With this you have a similar lumens in the top of ramp with 5× 7135’s and maximum power with double click, like others Anduril flashlights.

A chance to get on the GB list? or or of the batch codes being sent out? If you are already on the GB list, have patience,they are under production now, and they will build them before beginning to send out the codes, (so they can be shipped right away once they are ready.) Also see post #9127, page #305.

For anyone interested in USB-C docks, here is a reputable review of several types. I had no idea how expensive some of these are.

I can confirm that black will be one of the colors available, but I can not deny or confirm any other color options at this moment.

I’ve been worried about this ever since I first saw at the driver PCB photos. Especially, because I plan to use NCR18650GA (semi-)flat-top cells.
What is your opinion about simply removing the pot? IIRC, it was mentioned earlier, that currently it does not have any real use (it could act as a current limiter for an optional locator LED, which is not mounted by default).
It could be desoldered as a DIY “mod” by the users who want to use flat-tops, OR it could be omitted to begin with (i.e. not mounted in the factory) in future batches.

I believe that is the long term plan, but I’m also guessing the next batch (in process) will still have it.

I’ve had feedback that the Sanyo NCR18650GA gets close to, but does not touch the trimmer.
As I get more feedback or direct information I will share.

The trim-pot resistor at this time is dormant, and it could be possible to remove it if you wish. as it was a feature added for modders, it has been discussed by the team and its likely it will be relocated in the future lots.

I removed the trim pot on my LT1 with a small flat blade screw driver. Warning: Do not attempt this at home. Big Smile

First just the screw part of the trim pot, but a post was still sticking up.

So I used the screw driver to remove the pot completely, a bit of clean up with some side cutters.
No concern now with my laptop pull batteries somehow shorting on the trim pot.

Note amishbill’s rolled up cheat sheet between the cells. Thumbs Up

Looks like the tabs you find on cells from commercial battery packs.

I guess they were salvaged from a battery pack (laptop battery, etc). What you see on top of the cells seem to be the remainders of the metal tabs that used to connect the cells in the pack together. They are now cut and folded to act as makeshift “button tops”. Neat trick.

I tested a number of different flat top 18650’s to see if the trim pot was an issue but none of them made contact with the trim pot. So perhaps it’s a matter of manufacturing tolerance that’s causing contact with some of the LT’s?

Man, just got a big “ah ha” moment. I’ve been pulling off the soldered tabs on my laptop pulls, then scraping pliers over them to flatten down the sharp bits. Doing what you did, simply clipping and leaving the main tab, makes perfect sense. I feel so… stupid. Ughh

Don’t beat yourself up too far. You’re not the only one to figure this out after totally stripping too many cells.

Exactly.

I wasn’t worried until I took a small straight edge and noticed that the trim pot on my unit did stick up above the battery ring. You can see the cells I’m using are not exactly clean on top, so I just opted to remove the non-value added for me trim pot. Now I have no concerns.

A note on these “button top” laptop pulls, one can do a much cleaner job than I did with the left over tabs, but these are functional and safe as best I can tell, so I left them as is. Like others, I used to completely remove the tabs, but when I was preparing for the LT1, it made sense to leave on the short tab and fold it over for a equivalent to a button top cell. I’ve got 50 of them, so I’m hoping the extension tubes will come to fruition.
