Default Which battery pack for .46 sized glow?

Hi,

I bought an avistar elite (.46 glow)and will replace the AA alkaline battery pack with a NiCd or NiMh pack.
I will also kit build a four-star 40 and need a pack
I also have an extra 300 (.46 glow) and need a pack too.

I have 2 old (10 years) packs of 4.8V 600mah NIcad. Although they charge and seem to be ok, perhaps I should not trust them as they are pretty old.

After checking my local hobby shop which has ok prices, the cheapest is 20$ for a 4.8V 700mah pack brand name (futabo, Jr etc). Some higher capacity ones go for 40-50$.

Is there a brand and online store I could get these for less and still get something that is decent quality and reliability?
I don't want to go on the cheap and have a bad battery pack fail in flight, but don't want to break the bank either!

WHat capacity is good?

The best to all!

If your sure your staying with the hobby then I would suggest looking into lifepo4 packs.

You can also use a bigger battery so you can fly all day and not worry about recharging after 3 flights.

Something like this at 2300 mAh. http://www.hobbyking.com/hobbyking/s...iver_Pack.html

I use A123 packs for my more expensive planes and run these lifepo4 HK packs for my smaller stuff. Not all chargers can charge lifepo4 although most sold today do.
http://www.hobbyking.com/hobbyking/s...iver_Pack.html Does not show in picture but they come with Futaba/JR discharge plug.

+1 on the A123 packs, but the 1100mAh packs will give way more flying time on a charge than most folks will use in a day. Unless they only bring one plane to the field, but then the A123's charge so fast, topping one off during a lunch or coffee break is a breeze[8D]

These days, the real concern is how far the battery output voltage drops under load. The digital receivers don't much like low voltage dropouts.
Even a 2000mah four cell LMIH pack can under load, drop output voltage enough to cause problems. The load from such things as digital servos and electric retractable gear can trigger such dropouts.

Not a concern with the A123 cells[8D]. Their high "C" capability makes the voltage under load very stable, in fact more stable than any Nimh battery. With AA Nimh cells, if you want the lowest voltage drop under load, you'll never choose cells over 2000mAh, in fact, the traditional 1650mAh cells are the best choice for AA Nimh receiver packs. If you want a brownout, just try a 2700mAh AA Nimh pack

Are the A123 cells heavy?

So a 2 pack would weight how much? is it a bit heavy for a .46 glow sized aircraft?

Where can I get them at a decent price and a trustable source?

Take care!

The 2S 1100mAh packs I use are 3.1oz. I weighed the 4 cell Nimh I had lying around and it was 3.9oz.
A 2S 1100mAh pack is a great choice for .40-.60 size planes. When you run A123's and see just how few mAh's you put back in after a few flights, you'll be very surprised

Sadly my Rx cannot handle the voltage of a 2cell lipo but my servos can.

A123's aren't Lipo. If your receiver can handle a 5 cell Nimh, it should be just fine on A123/LiFe. I'm not aware on any receivers that won't support 5 cell Nimh/Nicd.

If you want A123 there is a chinese source on ebay sz_omg. ??? Anyway search for a123 1100 and also 2300 with a 100% rating. I purchased a lot of product in the past.
However our whole group use mostly HK and valuerc 1100 lifepo4 2s and 1800 and are happy so far. Valuerc have multiple connections which I like.

Yup.  I was buying that type of NIMH only 6v a few years back, but LIFE is really the way to go in my opinion.

Hello Pilot Pete, I know A123's aren't lipos. I use life on my Rx packs.

Hi,

It seems that the only way to get genuine A123s is by disassembling power packs. A123's site mentions that they do not sell cells, they only sell to OEMs. They say any cells sold on ebay and the like are fake most likely. They put out a document on how to spot fakes, and the ones I saw on ebay are fakes according to the doc. I suppose it is possible to find some genuine ones out there, but at what price?

Anyways, after doing some checking on ebay, I bought some 18650 sized Life cells that are 1800mah for about 4$ each, supposedly 10C according to 2 answers I got from the sellers.
I bought 6 of them to test and will check them as soon as I have them. As far as I am concerned for Rx packs, as long as the cells are reliable and have a decent lifespan, I am happy.

I will let you know how they turn out!

Thanks!

I assume you realize the A123 cells require a different kind of charge compared to Ni-Cad

Yes, I am aware, thank you.

Just bought a Hitec x2 charger for Li-fe, Lipos, ni-cd etc.
I already have a Hobbico 1300mah Life pack that charges just great with this charger.
