I just bought an Aerobird Xtreme and was looking at extra battery packs.
These two appear to be the same battery pack, just different color and price
7.2v 3300mah six sub c batteries

Some expert advice please,
MuddyThey appear to be similar, though one never knows what's behind the dark heat shrink covering of the first pack.:eek:

Since the seller is the same for both and he gives an e-mail address, why don't you e-mail him and ask what differences, if any there are between them?:confused:

The second sets appears to be Sanyo 3300s. :o

The company that makes these packs is Powerizer. Has anyone purchased from them in the past?

Are the Sanyo 3300s batteries good or bad?

Thanks for the help,

Muddy

Sanyo Batteries are very good batteries.

I have been using Sanyos for over six or seven years now under duress and they still "perform" as specified.:)

One thing that stroke me as interesting. One is marked Losi (on the URL) while the other one is marked Aerobird. If they were one and the same, why call them by different names then?:confused:

Why also is one 30 and the other is 2 for 30.
I was thinking that maybe rc plane guys will pay any price? I have no clue about the batteries as I am new. I just noticed that they appeared by numbers to be the same thing.
I had read something about how batteries are soldered or welded that can cause more resistance and therefore lower amp discharge rate.

I was hoping someone in the know would set me straight, I will email them and hopefully they will get it straight in my head.
I will post the results.

With the limited amount of information supplied by the auctioneer one is trying to do our best to assist you. In checking his auctions further I have found a difference in the two packs. One that leads me to believe they ones for the Aerobird are of superior quality.

Based on what you state, price wise, I would have to infer that the ones for the R/C car possess higher internal resistance and are not in the same league as the other one.

On the other hand, since the plane pack is covered in opaque heat shrink it is impossible to tell what cells are being used on that one. Some cells have higher resistance and do not deliver as much power as their equivalent Sanyos, yet in this case, it appears the car packs are Sanyos (?).

Here is where I believe the difference is, taken from the auction site on the Aerobird pack:

7.2V pack made of 6 x SC 3300 mAh NiMH matched cells. Specially designed for Aerobird Xtreme. aslo good for Fighterbird; Zig Zag Racer; Aerobird; Firebird Commander. Doule flying time than original Ni-Cd 1700mAh battery pack With standard Tamiya male connector. High performance with high capacity. Dimension: 2 1/2"L X 1 7/8"W X 1 7/8"H. Weight: 13.2OZ


From the LOSI pack auction:

High quality 7.2 V, 3300mAh, saddle shaped battery pack made of matched NiMH cells ( 6xSc) by solid welding.
Rapidly charged up and high drain current up to 35 Amps.
Ideal for Losi and HPI RC racing cars as well.
Connector: standard Tamiya.
Wire Type: silicon 14 ga.
Dimensions: 68 x 43 x 23 mm or 2 5/8 x 1 5/8 x 7/8 inch
Weight per pack : 336 g or 12 Oz.
Battery Size: Sub C ( 23 Dia.x 43 L mm or 7/8 Dia. x 1 5/8 L inch).
Yes, buy two packs directly from OEM Manufacturer, and you Save 70 % or more than any retail store!

The only ovbious difference here is the weight so I am inclined to believe them to be quite different from each other. 1.02 oz weight difference per pack is substantial. Since the packs are six cells each, I am sure the extra wire supplied with the Aerobird does not account for that weight difference.

Hope the auctioneer can clear this up for you. :)

Here is the email I sent and their reply.

I am looking for a battery pack that is 7.2v sc6 3300mah. I noticed that you have two similar packs and was wondering if you could tell me the difference if there is any. The part numbers are RA-HSC6R2MT and RC-HSC6R2TMx2.
Is there any power difference in discharge rates? Why is one about half price of the other?
Thanks,
Robert Frederick



Their reply:

"Thet are same cells, but packed in differnt way.
RC-HSC6R2TMx2 was packed in our China factory
RA-HSC6R2MT was packed in USA for smal qty"



So what do you think?

I would go with the ones made/packed here in the States. I have a notion they are better matched and of possible better quality than the ones that come prefabricated from China.:o

If they were exactly the same, why is it that the ones assembled here weigh 1.02 oz more than the Chinese ones?:confused:
