    Default 18650 to 32650 sleeve?

    Is there such a thing as 18650 to 32650 sleeve? I see many 18650 to 22650, but none for 32650.

    Thanks.

    It's kind of wasting space but still easily possible to make such a sleeve. Since 26650 will fit in 32mm diameter and almost same length of 18650 but more capacity, therefore people are interested to use higher capacity cells and for same reason, they spend some money to bore out 17mm bodies to convert it to 18mm cells or just buy such an aftermarket bodies.

    Thanks for the reply.

    I just acquired a Lumintop SD10 which takes 3AA, 32650, and 1 D cell. I have bunch of 18650 lying around that can power up the SD10. So I thought getting a 32650 sleeve would be nice.

    you are out of luck... I just tried to fit a 26650 adapter inside a piece of 32mm PVC pipe...no go, the inside diameter is 25mm.
    I assume you can make it fit if you slit the pipe lengthwise....

    rom a fellow SD10 ower...

    well, I just remembered i have some 26650 adapters that are just PVC pipe. These barrely fit in a 32mm PVC pipe. I *think** they came with the older style Convoy L2 flashlight.

    But I thnk you can make do with 2 sleeves, out of 32mm and 25mm PVC pipe... battery will rattle a little.
