Heya guys, I have 5 emolis (emolii?) on the way, have yet to figure out how to charge them. They won't be in a pack, so I'd like to charge them individually or in a rack as singles. I have a lith ion 18650 charger that slides to also charge rcr123s but it won't go 3mm longer so I'm stumped. I'd just run jumpers off the contacts but I've read a little on the subject and it seems maybe I need a more powerful charger. I haven't found much info on the emoli, but the a123's they say need to be charged way faster than 1 or 2 amps. Hmmm. Any insight would be greatly appreciated, actually I'd like to be recommended a charger that won't break my bank and will work for these. My dream setup would be a smart charger that'll shut off at 4.2ish on its own. They're 70mm long and 26mm dia. Thanks in advance.

Re: Emoli charger?

arent emoli has the same CV/CC charging algorithm as normal 3.7V lithium? if so you can use your normal LiIon charger.
 
Re: Emoli charger?

I use my magnets on a single cell....which you could connect to the terminals of your Li-Ion charger....but my official recommendation is to get a Lithium Ion charger that has aligator clip leads for the battery leads I sent you.
 
Re: Emoli charger?

Thanks guys, so far they showed up fully charged so I have a few days to shop before I have to have one. I love my nimh smart charger, it has a 1 or 2a switch, and an led that turns from red to green when it's done. on green it trickle charges. If I could find one like that it'd be awesome, but I know nothing of lith ion chargers other than the cradle ones that pairs of batteries snap into. Any recommendations Lux? What kinda amps should it push? I know I can charge aa's at 1a and d's at 2a, no idea on emolis... would the same kinda 1-2a charger work? Do they even make a lith ion smart charger with snap in aligator plugs? haha. Thanks again for all the help, this lil project is coming along nicely.

Re: Emoli charger?

LOL! Well there are completely different charging protocols ("algorhythm") that are used for Lithium cells. You can abuse Emoli and A123 like a cheap whore, compared to the more common Lithium Cobalt cells...and many have used many ways to charge these new chemistries...but I like to stick to using a Lithium charger which is going to extend their life and performance. For either Emoli or A123 18650 you can easily throw 2A at them.
 
Re: Emoli charger?

Hey Lux, if I use the aligator clip method off my spring loaded snap in cradle 18650 charger, will the red/green light system of charging still work or should I monitor it with a mm? If it will, will it say its finished at the correct voltage?

Re: Emoli charger?

Yes, emoli cells are nominal 3.7v charged to 4.2v max recommended by manufacture. And they can use Li Io which charges to 4.1v , Li Po charges to 4.2v

Re: Emoli charger?

Sounds as if the MOLI 18650 is the way to go if you want to run the MN21 on 2x18650. Been following LuxLuthor at RCGroups and am set to break out a few loose cells out of a Rigid 18V Compact Drill pack to test out. Likely going to charge them with the tortoise Pila for now, will hit them with 2A when the Triton2 arrives.

Hi Galen,

Emoli cells or the company have changed over the years. In 2005 they advertised 3.8v nominal charge and 3000Mah capacity for 26700A cell. Don't know if it is truth in advertising pressure that brought about a new found honesty or actually a change in composition of the cells.

To verify current up to date spec information, just notice the date on spec sheets or photos of the cell. the date code is the last 2 digits.

18650 cell current advertisement from company list nominal voltage 3.75v.

Re: Emoli charger?

LOL...round and round we go, the http://www.molienergy.com/products.htm website link is obviously out of date, as the two listed "ICR-xxxxx" cylindrical cells are the old Lithium Cobalt chemsitry that has no bearing on Manganese safe chemistry, hence my posting of the relevant current links in my last post. If you click on the links on that page, you see this data page is from 2002 in bottom of box chart. :eek:

The manganese cells from these various tool battery packs which I posted in this thread all have the "IMR-xxxxx" designation, where the "M" represents the safe Manganese chemistry, and with the specifications I last posted.
 
Re: Emoli charger?

The cell I've been writing about is the 26700 which has a nominal 3.7v. I like to know the manufactures recommendation.

That is in my 2nd post. I do not feel compelled to debate the obvious.

http://www.swift-tuning.com/EMOLI_26700A.pdf notice the picture of the cell and that it is made in Canada

January 17, 2005 -- E-One Moli Energy (Canada) Ltd. (Molicel®) announces the launch of the industry's highest power lithium-ion cell for high-rate applications. These cells are the energy source for the world's first complete line of lithium-ion cell powered, cordless professional power tools. These 28-volt tools were introduced by Milwaukee Electric Tool Corporation at the International Builder's Show, held January 13 - 16, 2005 in Orlando, Florida.

The emoli cells I have used in the past and continue to use come from Milwaukee battery paks. These cells are only made in Canada.

It is interesting for a progressive technology company to still keep their ICR Cobalt cylindrical cells listed on a Jan 2008 updated web page, but that is the reality. Also that is Canada. LOL!

I like to rely on the data from the MoliEnergy Headquarters & Production facility website which is in Taiwan, and make sure I present information on Manganese safe Lithium cells which is what we are all talking about. :thumbsup:

Re: Emoli charger?

Jim, I am not trying to antagonize you...rather I'm saying that the only official Emoli link of specifications about these new manganese safe chemistry cells that I have been able to find is on that Taiwan site, where I posted the two links for both cell IMR-xxxxx part numbers. These spec sheets have slightly different (but not important on a practical basis) nominal specs, and I have not seen an official link demonstrating that there is a separate spec Canadian manufactured version as you posted....but maybe there is.

I know you are trying to help mr.squatch, which we all appreciate. I am more pointing out that the Canadian product list for some reason is not up to date with Manganese links, and it makes things confusing until you realize the ICR-xxxxx on their site is their old Cobalt Lithium Ion cell from 2002. That's all.

I also appreciate your posting of the swift-tuning website pdf as valuable testing data, but that is a retail RC hobby reseller.

Again, there is a wide latitude in charging (even overcharging) these cells, and I think we are all on the same page trying to help people learn about these cells, reduce confusion, and use them properly. :thumbsup: Thanks for your understanding. :)
 
Re: Emoli charger?

Lux, I've provided you and anyone who cares to look with a link of the Canadian site where the battery I have spoke of is produced. A nice news press release with link.

Lux your talking about a different battery made in a different place. It is that simple. Red herrings only obviate you bring up an old cobalt battery.

There is no need to try to make this personnal, your not antagonizing me. And this thread isn't about you.

Re: Emoli charger?

some things are not black or white. second link has the pic of the battery in Milwaukee paks. it's date code is the last 2 digits.

For chargers you can use a older Li-On 4.1v program or Li-Po 4.2v program. Notice how all the links mention 3.75v nominal.
