MTN Electronics: LEDs - Batteries - Lights - Chargers - Hosts - Drivers - Components - 1-Stop-US Source

Maybe, but I have seen those notices there before and they seem to have just been away as the notice states. Maybe it is Utah :new year” and they are simply doing like Simonb did with hos site for Chinese new year. :wink:

When your a Husband/Wife company —- the only way to truly get away is close the site for a few days

Yeah give them a few days. There’s no better US based small company to deal with

Looks open

Yes. Was chatting with Richard earlier. Such a great resource!

Agreed, MTN is a great store!

I’m getting my latest order any day now. I don’t think I want to add up all my orders with them over the years. :person_facepalming:

I do miss Richard’s posts here on BLF though.

Same!

I have so many of those little brown boxes stacked up with parts etc

I keep the invoices because they have the minute details of my orders. That can help for inventory and driver specifications when swapping between hosts.

Richard has hand written some very helpful notes when ordering for project lights that we have discussed.

I have every invoice in pdf form, in date order, with notes I have added as I wanted. Plus a spreadsheet of what parts went into what lights. And who the lights were given to. I have all the boxes used for assorted storage too. :smiley:

Lol! I was just contemplating doing that, then OCR them and add to some spreadsheet form.

I finally got rid of all my MTN boxes about a year ago and put my parts in a large drawer of a parts bin. After awhile I had a hard time closing the lids of the boxes I was using and it’s nice now to have all the parts together in 1 spot.

I have a flashlight file in my file cabinet with all the receipts from my orders. And a spreadsheet with part costs and flashlight totals, and other calculations. But I dare not share that with anyone in my family!

And I have a box full of my flashlight boxes. Why? I don’t know. I guess if and when we move, it would be good to put the flashlights back into the boxes to keep them safe.

I have a number of plastic boxes with movable dividers, all labeled and segregated into types of parts. Up to 18 small compartments or fewer larger ones. Very handy for many small things. And several used for small machine screws, #2, #4, #6 in assorted lengths and head types. But I also use a bunch of those MTN-E shipping boxes for things like silicone wire of differing colors and gauges, and a bunch of miscellaneous things. A large carton of assorted boxes from lights I have bought too.

Dang I thought I was the only Maniac with all these parts —- I use to buy by the dozen — Right now I have a multitude LEDs —every kind you name it — at least 100 drivers with every sort of firmware etc —- this adds to the over 300 lights I have — I tell my wife, she has no idea what I have laying around —- Then there’s my battery addiction, a whole other story — I showed her one day a box of these LG cells ( comparable to a 30Q ) — I said this little box is worth at least 300- $400 ( 275 cells in ea ) I have 10 boxes of those ,several boxes of Tesla 21700 —- numerous other cells —- Damm just reading this back is crazy

……and to think, I felt guilty with the 12 spare batteries I bought on sale a few months back (when they were available). Didn’t really need them, and save for the new 18350’s I rotated into lights for a couple of cells of lesser quality, no idea when I’ll use them. Hopefully they have long shelf lives. I couldn’t imagine a stash numbering in the thousands!!

If you store your cells at 3.83 v and in climate controlled area they’ll last years — I have some Sony, Samsung, Etc that test as new over 5 yrs old

I build big battery packs—- Those LG cells are intended for a Portable Solar Generator— Just have to get around to building it

:+1:
I’m curious about the “3.83v” storage charge, though. Seems most suggestions I’ve read say between 3.6 - 3.7 (where most of mine are at). Why do you advise 3.83?

That’s odd — most of what I’ve read say 3.83 v —- even the hobby charger I use defaults at 3.82 v in storage mode —- I usually set it higher 3.87 v and check the settle voltage the next day

CPF thread

Just one source that references storage SOC, but there are a couple of links….lots of variation, and probably dated info, but nonetheless something I read when I first started getting into the hobby flashlight world. Although the differences seem to infer it not be uber-critical to hit a particular benchmark to insure max longevity, I’m more inclined to emulate the practices of an individual with your knowledge and experience over the long run. Thanks for responding!

The one thing I do know — Good Cells last a long time — Not so good cells don’t — Efest are the worst — Also I’ve had bad luck with Shokli 26650
