    Default Self-cut Mag 1C SSR-50, 2x25500 with 10Amp tail cap switch, Fully Driven to 5-6A mod.

    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.

    You need a protection circuit on each battery. The circuit keeps the individual cell from discharging below or charging above specific voltage levels. If you run with one unprotected cell you run the risk of that cell getting out of tolerance and going .

    I am looking for a relative answer, Obviously, running 2 both protected is safest, but that's not the question here.
    I was running 2 Un protected C Li-ions before,
    wouldn't be replacing one with protected cell is still safer than running both unprotected?

    Another way to ask the same question:

    Given 3 batteries: 2 Un Protected & 1 Protected & Runs two in the light,

    There's only two options:

    Option A: Run 2 Unprotected
    Option B: Run 1 Un protected + 1 Protected

    Which option is safer? A or B?

    Hmmm ..... will the Modamag tail clicky handle 5-6A ?
