Sold/Expired WTB: High Current AA to D cell adapters for 4D Maglite (stock size) [shipp to Norway]

Zepticon · Jan 18, 2014

Hello

Im looking to get my hands on two sets of high current D-cell adapters for a 4D maglite. Any configuration is interesting, but i need atleast 8V to the driver using AA batteries.
Let me know if you have anything that might be usefull

even in a 12aa/4d holder you'll be up around 14.4v on NiMH rechargables. Might need to pick up a few dummy cells if you need to get down to 8v. Might be equally as feasible to use eight 1/2D cells for 9.6v.

You mentioned "AT LEAST" 8 volt but what is the maximum voltage?
You may consider about 16AA in bored out 4D Mg.

Nominally 1/2D cells are actually 36mm long. Therefore 8 won't fit in 4D M*g and 7 will fit if tail cap is modified.

According to previous similar post, will be using H6Flex driver so 21V max.

So I suggested look for either your or mdocod's 12xAA adapter used...

I dont have equipment to get the mag bored. And getting it done proffesional would be insanely expensive in norway

The minimal voltage is about 8-9V and maximum is 21V. Its going to use 6600mA at max load.

And the reason i posted here was because i am looking for either a fivemega or mdocod adapters used

What modifications are needed to the tail cap for the 7x 1/2D to fit?

You will need to bore the tail cap.
Or get 38 mm extension tube to use 7x1/2D or 60mm extension tube to use 8x1/2D without boring the body or tail cap.

Now that is interesting!
Those 38mm adapters, are they smoth surfaced or "gripped" like the middle of the light? If they are smooth, then they are the best option i have seen so far.
Is there a tutorial somewhere regarding how to bore the cap? I have access to a lathe so i can get that done if need be.

But will 7x 1/2D cells be able to handle the drain??

You need to bore out inside tail cap so spring gets further in.

3500Ah 1/2D cells are capable of that load.

They are griped (knurled).

Ahh.. I would prefer to keep the smooth end surface. I am a sucker for aesthetics (thats why i got a mag).

I have access to a lathe, but it does not have the equipment to bore the inside of the mag all the way in. But the cap is so "short" i can get it done with a regular iron.
This has been enlightning. Thanks a lot! I will try the end cap mod, and if that doesnt work, i will have to get creative.

Where do you recomend me to get those 3500Ah 1/2D cells? Any quality brands?
