    I'll have to mock it up when I get home, but I wonder if 2 x 2 18650's side by side fit in a dual bored 2D form factor?

    Bare they might fit but any sort of adapter that adds length is going to make that impossible. 2.5D is really ideal for this configuration...

    I will definitely put an assortment of 18650 side-by-side adapter designs on the list of things to build in the coming months.

    The sizes I have in mind at this time are as follows:

    4x18500S>2D
    4x18650S>~2.5D
    4x18650S>3D
    6x18500S>3D
    6x18650S>4D

    If anyone thinks they'd like longer configurations for bigger mags that too would be possible I would imagine. Like 12x18500S>6D. hmmm...

    Not really true, if you look to this old mod you can see that i have made an adapter for the 2D mag.

    A little mod is required also at the bottom of the mag switch, i have trimmed about 5mm...and also 2mm of tailcap threads.

    I think it's possible to make an adapter for a genuine 2D

    At the moment IMHO some possible interesting configurations are:

    4x18650 4S >2D
    4x18650 2P2S >2D
    6x18650 6S >3D
    6x18650 2P/3S >3D
    10x18650 2P/5S >6D

    Do you know when you will have a 4D/12AA adapter available, what's going to be the cost on that?

    Hi wildstar87,

    I will very likely have a small batch of 12AA>4D serial adapters for button top cells only ready to go within the next 2-5 days. Most of the plastic parts are completed for that batch, so I just need to wrap up the metal end of things

    Price will be ~$38+S/H

    after several weeks with the 6AA to 2D flat/button cell adapter, i can say that it is not the best choice for button top cells.... even when using only the pressure from the mag spring, the copper contacts tend to crush in the bottoms of the cells, making some unusable in the button cell only adapters....

    I'm very interested to hear more about this...

    First let me offer this:

    I would be happy to refund up to the value of 6 of your AA cells, As well as make an exchange to a button top only adapter if you'd like... Or just let me know what you think is fair. If my adapter has damaged some cells I think it's only fair I offer to replace them.


    That said..
    Generally speaking steel beats copper hands down for strength, NIMH cells are generally going to be steel casings and end-caps, so I have to ask what cells you are using that are deforming under the pressure from the adapter. This would be good to know as the eneloops I have tested do not suffer from any noticeable deformations when used in these adapters. Also, just to double check, you are adjusting the nut on the end of the adapter to accommodate a light pressure on the cells within the adapter? I have had some cells from lesser manufactures, like Powerizer, have their tail-caps deformed even in normal consumer devices, so there becomes a point where the finger is pointed at the cell rather than than the adapter.

    I'd like to try to get the rest of the AA line filled out and on the shelf before diving in to any of these other 18650 oriented mag projects. I do intend to work on a full line of various side-by-side 18650 adapters for mags as there seems to be quite a bit of demand for them.

    I've been under the weather these last couple days, running a temp in the ~102 range so my productivity has been pretty useless. This week is pretty well shot for getting ahead unfortunately.

    hey Eric!

    the cells used in this adapter that were crushed are Titanium High Discharge AAs.

    the bases seem to be pretty flimsy.... may be steel but i can tell theyre weaker than the eneloops i have, some of which i crushed a while back after sticking them in a power drill...

    i really dont need anything, most cells still work fine and make contact currently in the other button top adapter, just reassigned them to a minimag.

    i also would need the adapter if i was to use the eneloops since their bases are messed up from mods before.

    just thought i'd let you know that this was happening so you could find a way to fix it.

    if you can widen the contact area where the bottom (-) contacts would go, this should spread out the pressure and resolve the problem. the main issue is that all the weight is focused dead center of the battery and thats also the weakest point

    That's exactly what I think I'll do. I machined a punch tool for that procedure from delrin, so I'll just make a point to make a new one with a larger diameter punch.

    I appreciate your bringing the issue to my attention.

    Default Re: Odd Mods Battery Adapters, Parts etc...

    very nice work!

    so now its May so were closer to the 5 and 6D adapters! i cant wait all that much....

    maybe you can rig together one from already machined parts? ill be more than happy to "test" one for you!

    on a more serious note, when you make new flat top adapters, i think the (-) contact should be about 6mm of wide circular, flat contact space. big enough to not damage cells...

    Hi Coolrricks,

    Here's a snip from the original post of this thread:

    ----------------------------------------------------

    12AA > 4D ~14.4V, for button top cells

    ~10 Available

    $38.00 each

    Add $4.00 for shipment to USA/Canada for any quantity up to 4 adapters.

    Add $5.00 for international shipping of 1 adapter, $1.50 for each additional adapter.

    Ordering 5 or more? Contact me for large order discounts.


    *Designed for use in 4D size MagLite's for custom modifications. Actual adapter length with cells installed vary slightly from the length of 4D cells, but has been tested to work in MagLite Body's with the stock spring installed. Not Stackable! Adapter shown/sold here can be used with button top cells only.

    Just an update,

    I should have 15AA>5D in both button top only and flat top compatible cell, 18AA>6D in both button top and flat top compatible, and also a special 21AA>6D in button top only available, all by the end of May here, just a few of each for now but enough to get things moving along.

    I think I figured out what to do with the 21AA>6D....
    Get those titanium power-max cells (only high current cells I know of with button tops available), and run a 64655, (24V 250W).... 10K+ bulb lumen .....

    Need to work on a high current switch for this with a nice ceramic socket setup and some heat resistant materials.
