    Rommul: yes you should get two spot if you want TWO separate adapters. Keep in mind that these for the 4/8x18650 adapter, you get the complete kit to do both 4x and 8x.

    Just a question....it sounds like you have two sets of 30. First $50 set of 30 for only 4 cells, and $70 second set of 30 for 8 cells, but only one list of numbers.

    I would like #5

    Lux, I made them as a complete set both 4x & 8x

    The reason why I offer them as each option is to save cost for the end user. I'm find another use the the excess parts.

    Just a quick question before I send the paypal. Is there an intention of having any 3X4X18650 adapters for the standard Mammoth and an extension, or should we plan on using an 8X4X18650 + a 4X4X18650 adapter?

    Also, just to make sure, we can series and parallel in all kinds of combos right?

    Say 4S4P for 14.8V?

    or 6S6P for 22.2V? (if using a combo of adapters)

    Are you saying The only adapter available now is the double stack that can configured as a 4x or an 8x. I want a double and one single I don't want to have to buy two double just to get the other single.

    Maybe i am reading it incorrectly.

    Also concerning the Sony Konion cells can they be charged using normal Li Ion chargers like the DSD. I any interested in about 4 of these cells.

    At any rate I know what I want and am ready to send paypal. Clear up some details for me so I can complete this.

    The way it looks to me now is:

    1 - 4x18650 adapter ... $50
    1 - 4/8x18650 adapter ... $70
    4 - Sony V Konion 18650 Cells $30
    Shipping $8

    Total $158

    Thanks again for making these.

    I think that should be 4S2P ie 2 parallel stacks which each stack having 4 cells in series.

    Modamag,

    Looks great! Yes, I'm interested to know the answer to this too. I purchased a Mammoth 8x18650, plus a 4x18650 extension. I would like an adapter that could work from 4x to 8x to 12x, but it appears that using a 8x4x18650 plus a 4x4x18650 may be too long. If I purchased two 8x4x18650 units, could I reconfigure these to a 12x4x18650 and a 4x4x18650?

    Thanks

    Action: I'm a little confused about your notation. But a 8x18650 would work with a mammoth and extension.

    For 14.8V, 4S2P, 8 cells, you just use a 8x18650 in series/parallel mode.
    For 22.2V, 6S2P, 12 cells, you just use a 8x18650 and one 4x18650 in tandem.

    These adapter are either Series (eg 4S1P) or Series/Parallel (2S2P). I hope I explained it right.

    Rommul: Your order is correct for what you want. Konion maintence is the same as other Lithium Ion (Cobalt)

    Rommul asked this question, which is still pending. It does not make sense if you want to use 12s 18650 to buy two 8s $70 holders just to get the center plastic cell stabilizer....and you would still need a longer threaded rod.

    In the Setapong standard Mammouth light, he is selling 3 body options:
    1) Shorty - 4s

    2) Standard which includes extra segment for 8s

    3) Extender tube as separate purchase which would give user 12s.
    Ideally, with your setup, people would want the $70 8s option, but then also need a second middle plastic section like in $70 model, and a longer center rod that would fit length of 3 cells. In that scenario, it would not work to get a $70 & $50 set. They would still only be left with the one middle spacer, and a rod that is too short, and a wasted set of end plates.

    Lux,
    I think Modamag was saying load up and 8S holder with batteries and load up a 4S holder with batteries and just load both holders into a 12X flashlight tube. You will probably have a little bit of current loss using the two separate holders, but the result will be 12 in series.

    That is if I understood him correctly.

    You may be right, but when you are dealing with 12s x 3.7V = 44 to 50 Volts, having an insecure connection like another set of battery end plates is not practical, and becomes an arc'ing risk...not to mention the resistance introduced.

    From my reading of it you just buy a longer center rod and cut it to length for a 12X. But Lux is right you will need a another center plastic piece even if you use the 8X holder. I think a part of Jonathan's post was cutoff and he was about to explain that.

    But I think the rods have threaded ends to screw onto the brass endings, so I'm thinking it would be best to have for the three long option (12s) which the Mammouth + Extension tube requires....an option from Modamag of buying JUST a 2nd middle plastic stabilizer/guide, and a longer threaded center post to use for 3 cells long.

    Default Re: Configurable 18650 Adapter & Adjustable Dummy Cells

    I am just glad Jonathan made these available. I believe I can use what I get from him and mod the holder myself for the 12x and 16X configurations. These were probably a lot of trouble to make and he probably did not want to make a lot of extra parts on the off chance that someone strange like me would want to do 16X configuration. Since the battery holder holds the batteries in compression and since the body of the light will keep the batteries in place once in the light, they would probably work fine without the intermediate plastic piece, as long as everything was needed in series. You could even run a wrap of electrical tape around the loaded holder where the intermediate plastic piece goes, instead of the plastic piece. That would hold everything in place for sure.

    I appreciate what he has done so much I don't think I am going to bug him about spare parts for my odd configurations.

    I don't see this as bugging him, nor am I interested in wrapping electrical tape. It is a question that is not yet answered in his description, which he may or may not have already addressed in his own mind, or he may not have realized that the stock Mammouth has 8s, and buying an extension then gives 12s. Modamag will see what we are asking and address it in terms of what parts he has now, or could have, and what is needed for the setups.

    I will understand if Modamag doesnt reply because his own 4 or 8 -18650 li-ion adapter was initially designed for his "The Colossus" which BTW has no mention of 12 cells. That thread only talks about 4 or 8 cells max. It was H22A who asked Modamag about his adapters dimensions so that the Mammoth would be able to use this special adapter. While I agree with Lux that a 12 cell option would be fantastic I am hoping that if enough demand is requesting 12 cells maybe it will come to pass. I have already ordered the 4/8 adapter because I was one of the ones who told Modamag that I would purchase one if he made it. But I would change it in a heartbeat if I had the option for one single style 4/8/12 adapter.

    Guys, the 12+ cells options should be made as follows.

    1. Buy a long 10-24 rod from McMaster and cut it to any length you need. But It's definitely require the stack spacer to maintain stability.

    2. I'll probably just flatten the + piece to allow full contact accross a 2" diameter. If you want this let me know in your order.

    I'll also look into making more of the stack spacer to allow more height. When I was testing, I was afraid of the overall length. Too long is unstable.

    Well, I am definitely interested in the 12 cell option but I guess I am missing something. If you flatten the + piece like you mention in #2 below, does that mean that I will lose some configurability? I am mostly interested in the fact that your adapter can be parallel or series so will I lose this option if I tell you I need the 12+ option? Also like you mention in #1 below will you sell me the additional stack spacer required for a 12 cell adapter? 10-24 rods can be bought in most hardware stores in my neck of the woods

    I don't mind buying rod from McMaster, but do the ends need to be threaded to tighten the pack together?

    If so, I have a basic hand tap/die set and could probably make threads on end of rod....but still need one more of the plastic middle pieces. I understand what you are saying about less stable, but these would be sliding into body, so it may work mainly for battery alignment.

    I also like the + brass nipple to push into Magswitch spring. If you are thinking of removing it so a single pack makes contact with a double 8s pack holder, would it work to just make an indentation on center of bottom (-) plate to match the + nipple?

    Starlight,
    #7 space is already spoken for, Jonathan just hasn't updated the list yet.

    Modamag,
    Since it doesn't seem to be a bother, if the extra spacers do become available, I would be in for 1 to 4 depending on availability. I will be working on some 16X configurations in S/P for long run times on high output hotwires.
