Emoli cells are incredible!

To be honest, if your simply somewhat competent, and pay attention, LiPos aren't unsafe. You just have to be careful.

Yeah. I guess it's like anything else; take care of it and it will take care of you.

As far as NiXX cells exploding - I've never heard of horror stories involving mushroom clouds or shrapnel. And I bet there are MANY people who don't charge/discharge them like they are technically supposed to. Just look at some of the cheap battery chargers out there that simply dump a relatively small charge current in them all the time.

Back on the Emoli topic. The Milwaukee V28 is 28 volt pack. How is it assembled, or more accurately how do you dissassemble the pack and reconfigure it for a lower voltage? How many "cells" comprise the V28"? How many volts per "cell"? etc.

I presume that the better Li-Poly & Li-Ion chargers allow you to select the number of cells, charge amps, etc.

Any additional advice would be appreciated!!!!!

If I'm not mistaken, there are 9 cells per pack. Just bust open the pack, disassemble, clean contacts, ect. and simply solder together like normal packs with battery bars.

DeWalt has new 36V Lithium-Ion "Nano-Phosphate" packs. Anyone know if these are like the Milwaukee's? I could devide this in half and have (2) 18V packs. That would work well with a Quark 125B, Feigao 9xl (or Lehner 1940/9T) don't you think?

BTW, I would only use one 18v pack at a time.

The DeWalt 36V packs are around $159 ea. A great deal if you can split it into two and have two packs for $159 and a couple hours of work.

To be honest, I believe those packs are gonna have to be put in a 2P configuration, so it would only be one 18V pack. There actually different type cells I believe.

There are 7 Emoli cells in a Milwaukee pack. There should be 10 A123 cells in a Dewalt pack, each with a nominal voltage of 3.2-3.3v and a full charge voltage of 3.65v at room temperature. Unless you have special equipment, the A123 cells are not ideal to charge. Also, I've read that you're not supposed to solder directly to the A123 cells (at the center is the pressure release point), which is why A123 sells a Developer Kit containing 6 cells each with tabs welded onto them.

There are some tutorials and the like on disassembly/assembly on Emoli/Milwaukee cells/packs.

So using the Emoli's with the Quark Monster 125b I should assemble a pack with five Emoli's instead of seven due to the voltage capacity of the Quark?

Considering (2) separate 5S packs to be used in parallel producing ~ 6000 MAH.

Also, it appears that the emoli's are significantly longer than the std sub-c nicad or NiMh presenting chassis fitment concerns on my FLM extended chassis supermaxx..

Lastly, what charger are you V28/Emoli guys using? Can I set the charger for 5S packs?????

Your thoughts METALMAN & SQUEE?

[cart213]

Any lipo charger can be used with the emolis. You would set it at 5S just like you would a lipo pack. I'm using a Schulze 330-d charger. And yes, the emolis are larger than sub-c. They are 2.7" long with a diameter of 1.1," so they may require some creative packaging in your FLM chassis.

[MetalMan]

There's a good chance that you might have difficulty assembling the cells into packs that will fit. You could try making 4cell stick packs with a 5th cell on top of the 4cell stick, otherwise their might not be another way to mount them in your chassis.

[cart213]

Oddly enough, I NEED an FLM chassis for my pede in order for the emolis to fit well. In the stock chassis, I have to stack them too high on the chassis, and you can see in the above picture what the result of that packaging experiment was. :rolleyes:
