any 6aa to 2d adaptors about ?

6S? If so I would once again suggest two of the 3S AA holders from CNQG.

Scaru, I could only find 4aa holders on cnqg, and at 33.5mm, will they fit an invited mag body?

fyi, the springs suck, change those, add a little solder and copper braid to reduce resistance, and these are ok.

The most I’ve done with 2D(actually it was an 8 AA carrier I replaced)is 10 nimh cells 5s2p and used solder tab Tenergy cells around a custom core. Ended up with a 4.2Ah 6V pack that I charge at 1/10C. I still have the mold but would need to buy more epoxy resin to make any more cores.

Those holders may fit in a new Mag. The Mag heatinks I’ve made are between 34.12 and 34.18mm, turned to fit snugly in their respective hosts.

Is that the pillar type heatsink to allow the focus to remain? If so, thanks for the heads up, I know what alu bar to get for when I get around to my 3d… :slight_smile:

Indeed-although I cut a circle the diameter and depth of the MCPCB that will be used for heatsinks that will be used with the MagLED reflector. I remove a little aluminum at time, then stop and check to see how the board fits; it’s done when the board ‘pops’ into the circle. In addition to centering the emitter, I like to think it creates extra surface area for heat to leave the board (along its circumference).

I was under the impression 14mm stars do the trick? Or am I miss-understanding you? I only ask, as that’s what I have, xm-l u2 14mm star for the project, I should pm you about this, we’re fairly scrapping on the thread, although the thread is also helpful with regards my dads Maglite…

those cheap adaptors aren’t going to be good enough, i plan on making a hot wire mod with the philips 5761 bulb

Do you mind if I ask where you got the bulb? And if they have more? This just got real interesting…. :bigsmile:

If you're doing a hot wire, buy the Fivemega holders and save some grief. Expensive, but well worth the price with a hotwire mod.

You can buy 3AA holders from one member on ebay, but they are very cheap. Sorry, very budget. Standard China quality.

ebay is your friend :slight_smile:

He’s not making the size i want anymore :frowning: but i didn’t realise that until i sent payment, so now i don’t think i’ll get my money back

Is there any reason not to use 2*26650 aside starting at 8.4v rather than 9v?

Yes the bulb will only take a max of 7.2 volts unless you get some sort of regulator. they are available on cpf but makes the build much more expensive.

Ah, fair enough. So the 6aa will be nimh then? What about using the holders linked but old lumens them into submission - copper contacts and hd springs?

Thats an idea, but was worried that the thing may melt due to the bulb pulling around 10amps

If the resistance is minimised, does that not minimise the heat? What AA’s can give out 10a?

well they use eneloops on CPF…

Fair enough, I suspected that’s what you’d be using, I guess 10a into six is a little over an amp each.
