This mod will may take me a while, I am dividing the mod into 3 sections:
Section 1. Mag cut down:
Silver mag 2C cut down to 1C size, Runs on 2x25500 Li-ion using ModaMag
McClicky Tail Switch. This will provide enough juice to drive SSR-50 to or over spec with long run time.
Section 2. Low cost 5-6A Driver build:
Not the twin shark driver that cost >$50, the goal is to make 5-6A driver for under $10
Section 3.
Add copper heat sink/Aluminum reflector, then finish up with beam shots to compare with Mag85 for throw.
Starting with Section 1. Mag cut down:
Mag 2C tube cut with a table saw, you can cut it with other type of saw, as aluminum cutting is fairly easy to do: Cut right above the switch hole:
The tube will go into the head only a little bit, need to go in all the way:
Top view, you can see that the tube is stopped by the threads,
I need to grind off the threads.
This is what I use to grind off the threads:
Now you can push the tube all the way in, 2 C li-ion will reach right under the switch hole. The tube will be JB welded with the head later when everything is done, for now, I just leave it here.
Both C li-ion are Dx 25500, one is protected, then other is not.
I am not sure if this is a good idea. I got 2 protected C li-ion but one is DOA, perhaps, running with one being protected is better than both non protected? Would like to know if anyone else have run 2 Li-ion with only one has protective circuit like this?
Size cmparasion, left to right:
Mag 2C, Mag 1.25D, Mag 1C size + tail switch w/2 C li-ion, Mag 1C stock switch w/1 C li-ion. You can see that this mod wil give you a host of Mag 1C in size but 2x mAh capacity & allow Buck driver to drive SST-50 to full spec. You can not drive SST-50 to spec (5-6A) with a single Li-ion. DX Li-ion states 5000MAh but is actually ~3000mAH, this will give you
about one hour run time Driving SST-50 at 6A or 1.2 hour if drive it at 5A.
To be continued...
