Paul,
I wrote about chargers recently in Stunt News and many times on here. If you can swing it buy the best charger that you can possibly afford. I've been known to push the I-charger 306B as it's one of my favorites. If that's too expensive and everybody's version of expensive is different shoot me an e-mail and maybe we can chat on the phone a bit one day.

Paul,Whats the kv on your motor? 3,4,or 5 cells?

The AXI 2826/10  is 920kv and 3-5 cell

Found this link.

So then went to this site.

Here are 4s batteries that range in all shapes, sizes and prices. 
Now what charger to get for these batteries. The one John listed did not seem to do two 4s batteries???
I would like to charge more then one battery at a time or balance.
HELP!!!

Thanks Dean!
I will have a look. 

What I have to offer may not be particularly relevant to stunt needs but I have had a bit of experience with chargers.

Firstly Bob Hunt reccomends the Cell Pro 10s, I've had one for about 5 years, and probably used it to put nearly 2000 charges through batteries ranging from 2s to 8s, and from packs as small as 400mah, to 6600 mah. It'll do the lot. It's a great charger, the only thing I don't like about the cell pro is the fact that it's a LI only charger. It'll take Li Fe, Li Ion, and Li Po but nothing else. If you have nicads or Nimh for your glow drivers and possibly other aircraft you'll still need two chargers. Also the Cell Pro doesn't have a discharge function. With that said it's great in the fact that it'll monitor individual cell voltage, give you an IR reading and also 'heal' overdischarged batteries (to a point).

Recently, after a few dodgy input power issues it developed some problems and is now in need to being sent back to the factory. I'm not upset as it's had an absolute beating.

I had to buy a new charger, and I can thoroughly reccomend the powerlab Chargers. You'll get everything you have in a cell pro, (if you go for the balance charger board, you can charge up to 6 packs at once) plus you get the ability to safely parallel charge, you can charge nearly everything (nicad nimh, lipo, PB) and the best bit is regenerative discharge.

Occassionly we go flying and will have a pile of packs charged, and for whatever reason we don't burn all the packs. With the powerlab you can program it to discharge your battery packs back into a Lead Acid battery, so rather than burning off your stored energy in heat, it's actually charging something. The other good thing about this is that you can really haul out a lot of energy fast, which is helpful for determining the health of suspect packs.

On another note, you always gets what you pays for, and I've been seeing some guys with packs that go funny quickly. I've seen packs that have been balanced charged off cheap chargers that are wildly unbalanced. A few cycles on the ol' powerlab brought them back from certain death though.


Sorry for the long winded post, but it's worth noting to new electricky guys what's what.

Short version: Powerlab!

The telephone has the answers you seek

A few of these chargers listed in this thread have been discontinued. 10s and 4s.

Right now I am looking for a mid range - 50-75 bucks that will balance and store.
I think I have learned I need a 4s battery and charger.
Not real clear what 4s stands for.
On information over load.  

4S stands for four cells. Don't ask why!!

By the way, I went for buying extra batteries rather than an expensive charger that will charge several batteries at one time at the field. 

You might think about spending just a little more and get a charger that will charge more than a 4s pack.  This would give you more freedom in the future to go to a 5 or 6s pack if so desired.

If you're ever in LA (lower Arkansas) let me know.  We have a great soccer field to fly on now.

Take care,
Jason

Short version: Powerlab!

For what it's worth, I switched to an FMA (Cellpro) Power Lab 8 a few years back and I love it. I can charge 6 batteries at one time at 40 amps (using their Paraboard) and be off to the field in but minutes. I've been charging at up to 3C with no problems whatsoever for more than a year; many charge at much higher rates... I highly recommend that you buy a very high-end charger (I-Charger or Power Lab 8, etc.) if you are in electric to stay. You won't be sorry about putting out the extra cash. I also highly recommend getting one of Will DeMauro's 50 to 76 amp power supplies. Remember what Dean Pappas says: "There is only one hobby; spending money!"

Go to hobby kings website and check out the Nanotech batteries in the 3.0 AH or 3.3 AH capacity with a 25C-50C discharge rating. The size will be metric but is easy to convert to inches. You'll need this to see if they can fit in the ship you are going to use them in. Chargers are going to be where you spend money that fits your budget. Take Will and Bob's  advice and buy a good charger that will serve you many years. I'm saving my money for an I Charger 306b.
