Battery Carrier mod help needed.

Is there an easy way to convert a 3x18650 battery carrier that is parallel into a 3x18650 serial? That or does anyone know of a good driver for 3xXMl to run on a single battery?

Thanks.

I’d say just pick up the soldering iron and some bits of copper. Or else, just buy the series one ($8 at FF, I think).

This is a picture of it, It's from the new Mystery Sky Ray. The driver in it stinks and I would like to use a DRY driver I have. What I wondered is if it's possible to convert this carrier into series. Do I just take the spring not connected to the switch and move it to the bottom? That seems like I would end up with a short and having it go Kaboom. But I really don't know. So If anyone knows can they please let me know.

Even if it's not a direct swap as-is it's probably less work in the end. Probably less flimsy than the original, too.

Thanks for the link but I really don’t feel like spending much on this light. It’s just not worth it to me. I tell ya the more multi-emitters I get the more I appreciate my old fandy fire UV-S5. It consistently kicks all the other ones. Well I do have a 9x trustfire that does blow it away. But that is the only one that does, stock anyway.

Surprisingly the battery carrier is well built that is in this Sky Ray Mystery Machine. Actually a little more solid than the battery carrier that comes with the BTU. Good solid springs, fits perfectly, won’t take the longer batteries though.

Yup, on the switch end, leave a spring on the switch. Put one of the other springs on the other end, and hopefully have a little copper nub to put back.

(And once you’re done, probably not a bad idea to feed it one battery at a time while checking numbers with a DMM.)

Me thinks you’ll spend more time & money on reworking it than the whole $8 a new series carrier will cost you, but again that’s just my thoughts.

You could be right. I suppose I’ll just skip it. I don’t think it’s worth the money, the heat sinking isn’t that great anyway. I ended up wiring it direct drive so now it’s at least close to as bright as the SRK but the beam is still goofy and it heats up fast. I know I wouldn’t have picked this for a project if I knew now what it’s like.

my beam is actually surprisingly even in my mystery sky ray. disappointingly under driven though.

its got some heft to it, and mine also heats up rather quick... but that could be a good thing. personally i would rather have the SRM (sky ray mystery) than a SRK for a project

Here's a parallel to series conversion:

Very cool, that is exactly what I was looking for.

Thanks a million.
