very cheap Li-ion cells
 

go to www.allelectronics.com and look under batteries and click under subcategory Lithium-ion and they have a battery pack with two AA Li-ion cells in it for $6.50 :eek: all you have to do is crack open the case they are inand there you go. Plus they have a charger for it for $4.50 but you would have to modify it to charge our cars. There is a whole bunch of things there for cheap at thrt site.

:eek:

Thats what I just about did when I saw them.

I already went that route. That's a great price for li-ions, yes, but those cells are huge. The dimensions are 2.5" x 0.75". You won't be able to fit them without mod'ing your chassis, and even then, your front wheel won't be able to turn without rubbing on the cells.

Here is a pic of a cell comparison, to give you an idea.

From left to right, RS AAA Ni-MH, Energizer AA, www.atomicmods.com li-ion, Panasonic CGR17500 li-ion, and 4 sony US18650S li-ions which are the ones that are inside of those li-ion packs from www.allelectronics.com. Much too big.

sigh.

aww man i thought they were like regular AA cells nowonder why they are more than 650mah. Oh well I will try to find them somewhere else.

Good luck. Be sure to let us know when you do.

ok guys if you want cheap, i mean cheap but good batts, then got to www.batteryspace.com, the have really cheap batts and good charger/battery combos. i got 12aaa and a computer controlled quick charger for only $19.00 - 5% coupon code "batteryspace" = $18.00 , great deal, also the batts are rated 750 mah, and oh man each charge lasts more than 30min. Great Deal!!!!!!!!!!-- Vtince

BTW, the batts are NI-MH

http://www.batteryspace.com does have the li-ion cells that are sold in 2-cell packs at www.allelectronics.com, but for $25 for a 4 cell quantity. I paid $13 at www.allelectronic.com and just cut them out of the packs.

If anyone is looking for the Panasonic CGR17500 cells that Jshwaa has pictured above cheap, I have 10 Brand New cells I will part with for $3 each. E-mail me at xmodspeed@wowway.com

Why are you selling them? Are you going to be selling li-ions in the future, or were you just experimenting with the CGR's and found out the same thing that I did.....they are a little chubby for any more than 2 cell installation?

Yup. Just an experiment. I ended up using a smaller diameter for my Li-Ion Kits.

Smaller, as in 14mm?

Was just reading this thread and found a good place to get those Panasonic CGR17500. $6 each, so buy from xmodspeed first, but still not too bad I suppose.

One thing I haven't seen is the discharge rate on these, when you say they don't do high discharge jshwaa, you mean like 1 or 2C?

Also, any advice on a charger if I were to try these out?

I'd be using these on 1/24 scales (see sig.) with 180+ sized motors. 2 cells.

Thanks in advance.

Yes, that's what I'm talking about. Most li-ions have a nominal current rating of 2C, from what I've seen. So the bigger the cell in mAh, the more current output.

Sanyo happens to make an AA sized Li-on, but I have no idea where to buy it. I'm still looking for it, and I'm not giving up.

Yes, Lithiums are VERY hard to come by! Sanya and Panasonic will not sell to you direct. They will tell you to contact an OEM who makes packs. They will not sell to you either unless you buy a pack from them that uses those batteries and then you need to pay 3 times as much and tear the pack apart to get the batteries.

Lithium batteries are strictly governed by the US because Lithium is a controlled waste product and raw cells can explode if charged wrong. Battery pack OEMs must sign agreements that the pack has a protection circuit to prevent this from happening.

So, us XMOD suppliers must find sources other than US to purchase Lithiums (China, Thailand, etc.). The problem there is you must buy in quantities of 1000+ or they will not even take the time of day to talk to you.

Good Luck! BTW, do a search for Yeah Racing LC 14500 ... That's what you need! ;-)
