Emoli sources?

[sLightlyObsessed]

I'm currently looking for sources for which to harvest emoli cells from...
I know that the 26700 size emoli with the 3ah capacity are found in the Milwaukee brand V28 battery packs (7 per pack) as well as the Ridgid brand 24v battery packs (6 per pack). But I was wondering... does anyone know if the Milwaukee V18 3ah battery packs also contain the 26700 size emolis? Also, how does Milwaukee reach that 18 volts with li-ion (18v/3.7v=4.86v , 18v/4v = 4.5)? Any input will help.

Should be something like 5 18650's in series (3.6v x 5 = 18v).

Thanks for the quick reply Bones. I found some very useful info by following those links you posted... namely this:
-->Milwaukee V18 and V28 series use MoliEnergy E1 MoliCel IMR26700A cell
DeWalt NANO 18/28/36V - A123 Systems LiFePO4 M1 cell
Makita LXT uses Konion/Sony 18650 sized 1.5 Ah manganese cells
Metabo Lipower - unknown, same as Craftsman's
Ridgid XLI - Emoli 3Ah manganese cells, same as Milwaukee v18/v28
Ridgid 18v - 18650 version Emoli
Sears Craftsman - unknown, same as Metabo's
Hitachi Li-Ion HXP - unknown
Bosch Litheon - Konion for 36v and LG* for 10.8V (*unconfirmed, most likely Konion)

According to this data, I don't necessarily have to buy the V28 to get the 26700 emoli's I want, I can get the V18 pack (5x 26700 emoli) for half the price which is great because I only need 3 26700's to do the 3D mag mod I have planned. With the additional 2, I can make a Li-ion powered ROP or mag61.

With the 3 26700 emoli's, I am going to try and power either a 64625 or perhaps a 64638 lamp. Has anyone tried this setup? Do you think these lamps will produce a good white color temp at this voltage (~11.4-10.8 volts)?
If these lamps need more voltage, than does anyone know of any other lamps that I might consider for 3x emoli's?

Additionally, I was thinking that 4x standard C size li-ion's would be better suited for the 3d mag mod, but I know only of the ones by AW which are protected and wouldn't work at the intended amperage. Suggestions?

Warning that some of these companies are changing their cell types. For example the Ryobi 18V with 10 x Emoli 18650 has been changing to Sanyo Konion type.

Also note this thread. The pack makers are using 3.6V nominal to get the 18V with 5 cells, instead of 3.7V nominal.

Thanks for the info Lux. Is there any evidence that the Milwaukee V18 packs might not be using the 26700 emoli then? I am not terribly interested in finding a pack with 18650's in it (but when I am, I'll be sure to stay away from the Ryobi), as I am concerned with purchasing a pack and it not having 26700's in it. Do we know for sure whether or not the Milwaukee V18 pack contains 5x 26700 emoli's? Furthermore, should I trust this post that jim found stating that, in fact, the V18 pack does contain 26700 emoli? I would be upset at myself if I got it and it had 10x 18650 emoli instead. Should I just spring for the V28 pack and put my unneeded cells up on B/S/T? What I'm really looking for is higher mAh's and non-explosive chemistry (as well as a push in the right direction ).

*In reply to my own post above, I found 2 posts which reference the setup which I intend to build. Both of which were posted by jimjones. They are found here and here. In them he states that he is satisfied with the light that 3x emoli and usl lamps (such as the 62138) produce. This eases my concern with amount of light and color.

It kind of makes some sense that an Asian Ryobi company would switch to a Sony/Sanyo type of cell, rather than a Canada based Emoli brand. They are both safe Lithium Manganese cells however.

Regarding the Milwaukee V18, you are best doing a google for them to see if there are any reports of a battery change. TBH, if you are careful, and get a pack from a place you could return it, I think you could peek at the cells without doing any damage. My strong guess is that a Milwaukee named tool company would be less likely to switch.

The only thing I don't know is if there are any patent infringements or price issues involving Molicell that makes the Emoli brand. The other major safe chemistry, A123 brand, has had some Nano-Lithium-Iron Phosphate patent/trade infringement issues. I don't know much about it all except that it has delayed their Stock Initial Public Offering "IPO" I have been waiting for.

I searched google and located a similar thread on rcgroups.com, where I found some reassurance (post 3). This is a primary source stating that there are 5x 26700 emoli cells in the Milwaukee V18 battery pack. I'm going to place an order tomorrow to see for myself.
