Chodes also approves. 
Interesting.
I have never completed a parallel holder in my head, close to this would have been 2 slots in the tube, perpendicular to your tube cuts, and have the positive connectors flexible, placed in as cells are loaded. Never thought of splitting the whole holder.
Curious to see the finished holder.
RaceR86 approves! :)

I’m watching. OL, could you take some detailed photos of the master slave setup? I plan on trying it, and think I’ve got it sorted, but every thread with photos always seems to have a wire or something blocking a crucial part I need to see.
Ps. Where do you get your triple reflectors.
? What is going on here. No torch OL has a torch and need I say what batteries?
Just when I think I’ve seen it all some other creative idea comes along from you know who. 3 amps to each emitter will create lots of heat. Should blind the bad people in this turbo mode. Even medium should put out a heap of light. Its good to hear about the new job. I hope my bad luck on you with electrical stuff was just a passing thing. 
Edit. Suncoaster and his better half have just left after a very pleasant evening of banter and he showed me how to use the modes on your 3C MTG-2 light. What an amazing driver.
Lithium and a flashlight for yourself... times have changed! ;)
Always reading your threads with great interest!
Very creative , as usual .
Very innovative, like what you’re doing here.
Panasonic NCR18650PD’s will give you the amps you need while also having nearly 50% more runtime as compared to the Samsung 20R, 2900mAh vs 2000mAh. Kind of a no-brainer there.
Does not have to be a Mag switch. Any clicky (on/off) switch would work.
Also, this post describes a shortcut and this one decsribes it better.
I got mine from tearing down other triples, but I believe you can get them here or here, OP here, or here, but the last one is deeper than the others, I believe. I think all of mine came out of SRks.
Maybe you should get him to move closer, 
I don't have a torch, I never keep 'em long enough. Actually, it's just a different posting with the old job, but it's quiet at night and it gives me time to mod, errrr.... I mean time to do my job correctly.
Have I understand this right that a C maglite has the same head as a D one?
Some dimensions are the same. The OD at the bezel end is the same. It will take the same bezel, lens, reflector, but of course, the bodies are different, so there are different ID and thread measurements. Also the outer taper profile it different because of the smaller body as well, so, put the two next to each other and they do look different.
Thanks for the clarification. I am absolutely unfamiliar with maglites because they are to expensive here.
Would a par16 spotlight mod work for a c mag as well?
I do not know for sure, since the threaded area inside the head is so much smaller due to the C sized body.
Yes it does, I did it.
Check that $2.24 Triple emitter mag mod for pics
Sorry for the off topic, now I have found it…
Ain’t that the truth? :bigsmile:
Always good to see a C Mag mod. The 4C is ergonomically my favorite medium-large size light. I’m fond of the “pre-C” versions particularly because the head/body have quite a few (and tighter) threads, which eliminates any of that very slight wobble that a lot of newer C Mags have.
Mod on, OL!
Especially interested in the battery holder.
Well, there’s a couple more photos of it in the OP now.
Because of the price of copper, anything made with it now, becomes jewelery!
