Cheap 3aa->1d battery holder

[f22shift]

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 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!!

Series or parallel? Got pics?

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 :hairpulln 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.
