i'm not sure if this belong here or the battery section but i figure this is more of a mod.
basically taking the kaidomain 3aa carrier and upgrading it for less resistance. i'm not sure how long it'll last but it does work and with stuff you might have already=cheap upgrade.

i used desoldiering braid which is made of copper and a penny-like :whistle: coin. destroying currency is a federal offence? and some epoxy

anyway,
-take a kd carrier. cut it in the middle. use a thicker saw because have the missing space will help.
-remove the stock metal
-epoxy the braid in the same configuration as the stock metal. i fold over where the battery would make contact for some flexibility.
-grab something penny-like. it'll probably be very dirty so you can sand it down with a dremel or even sand paper. something before 1982, should be 95% copper. use this on the tail end because your spring will twist on it. epoxy that on.
-don't forget to mark the + and - configurations.

any comments or tips would be nice. anything to improve the design.
the reason why i want the gap in the 2 pieces is that when it's in the flashlight, the spring on the carrier and squeezes the contacts with the battery ends eliminating the need for a spring in the carrier.

pics coming..

I've been trying to mod mine for a long time. About 4 months ago, i got rid of them with a light that I made so I can't play with them anymore.

I like your style, I like your moves.

Keep on keepin on!!

I have a few of those, and one night I just took some of the desoldering braid and followed the original electrical paths with it. I will try to post some pics tomorrow with before and after vbulbs if I can.

I did damn near the same thing but instead of using the KAI batt holders i went a cheaper route and used Plastic Film Canisters they are the perfect size for 3 AA bats and fit great in a D Mag.

made a couple 3aa to d and 1 6aa to 2d adapter this way working great so far :)

for the 2 d i cut out three equal size pieces from the canisters including two end pieces and for the 1d i just cut two ends obviously:)

its actually very sturdy and easy to use :)


sorry for the OT great job!!

no pics this time around next time i put one together i will remember to snag some I actually ended up using the same housing to hold my 6aa battery pack i just soldered the bats together then soldered the braids between the bats and mounted in the canisters for stability :) i can get a pick of that but its wraped in electrical tape and really just looks like a battery pack :)

while trying to decide my goals i built a couple of 3aa to D in series and in parallel. i only ever built the 6aa in series though :)

i might be able to give you a breif rundown on what all was involved if you want..

in a new thread of course :)

Just wanted to thank f22shift for the post. I've been wacking my brain :hairpull:eek:n how to make my own makeshift holder sturdier. The front & end cap was always trouble for me.

Here's my tribute to you in a 9AA to 3D parallel version.

The only improvement I made was to pin wooden sticks (alright, they're old cutdown chopsticks :naughty:) to the holders. The front portion is epoxied to the sticks via metal pins & the rear holder slides off the pins for easy removal & loading. I currently have rubber bands & magnets on the setup right now b/c it's currently jumpered & powering a build I am testing(only running 6AA during the test, hence the open slot.)
Here's a quick pic.
