Default Lipo Battery prices

Hi,

i recently purchased a KDS Innova 450QS heli.

It came with a KDS 2200mAh 3S 20C battery. I want a second pack and have two queries. Please help

1. I have been searching eBay. The prices vary by big margins. for the same ampearage and Capacity (2200, 20C) USD 40 to USD 116!! What is so different??

2. The original pack was 20C. If I buy a 25C can I continue using the same charger

Cheers
Lucian

Connectors - a battery with bare wires costs less than one with connectors. Type and quality of connectors also change the price (like gold vs aluminum).
Wire gauge - even though all the batteries are rated at 20C, they'll still have different wire gauges.
Quality - construction and materials can change price - but more expensive isn't always better quality.
Pick some out, post links here, and do a google/yahoo search for a review.

Thanks buddy

I did quite an extencive search before posting. General rule higher the 'C' - capacity higher the price ( Capacity is something that cannot be verified). Build / manufacturer also effects. The connector influences the price a bit. The specifications do not mention on connector material or wire guage. I have given three examples below.

Also my second question can I without fear use the KDS Charger for different capacities? (20C, 25C).

Gentlemen please please help I'm newbie to Lipo. and have heard lipos must be cared for much more than nimh packs


example High:
description: KDS 11.1v 2200mAh 20c price on ebay USD 122.99
Link: http://www.ebay.com/itm/KDS-Helicopt...7#ht_534wt_932


example Med:
Description: Walkera 11.1v 2200mAh 25c price on ebay USD 71.49
Link:http://www.ebay.com/itm/Walkera-25C-...item5d44a6e145

example Low:
Description: Rotologic 11.1v 2200mAh 30c price on ebay USD 26.90
Link: http://www.ebay.com/itm/RotorLogic-L...#ht_1611wt_932

The 122.99 must be a mistake. I personally wouldn't shop ebay for batteries.
As far as I am concerned, ThunderPower is the gold standard, and you can get the
newest 70c G8 in the size you need for about 60 bucks direct from Thunderpower.
The 45c G7 is even a better value at about 45 bucks. To some extent,
my experience has been that you get what you pay for, but you might be paying for
something (high c rating) you don't really need.

If you want to go cheaper, I've had good luck with GensAce, from Hobbyparts.
Another brand I've had good luck with is Glacier, from EPBuddy. The 3s 2200 35c from them is about 25.00.

I don't know anything specifically about the KDS charger,
but in general, lipo chargers will charge any lipo battery regardless of the c rating.

804 is correct about the charger.

You should look at what the manufacturer tells you the max charge rate is and not exceed it.
Most modern LiPo batteries will charge at 5C with no problem.
Charging at higher rates does shorten battery life.

Yes be CAREFUL with LiPos and LiIons they will explode and burn if abused
NEVER puncture them, that is a melt down situation.

Maybe when they first came out, but far from it nowadays. What you want in a battery is at least a 30C. Heli's are harder on batteries and anything less than that you are doing yourself a disservice. For price and works good, glacier batteries have been getting rave reviews and nothing negative to date. Just google Glacier lipo's. I know EP buddy.com sells them. As said, stay away from Ebay when buying batteries unless you are buying a well-known brand. Buying cheap lipos on Ebay is a crap shoot.

Even the high priced brands vary in quality.
Perhaps the most annoying is when "high quality" batteries balloon for no apparent reason,
and others of the same brand, size, usage, etc. do not.
The most common cause seems to be storage at too high a charge level.
The next common fail mode is single cell failure, almost always in the middle of a pack.

For me it doesn't matter if it is in the middle or not, the pack is gone. For the balloon, I had a Haiyin pack out of blue had a cell go bad and puffed some at the SW heli Rodeo a few weeks ago. I don't have much faith in the pack now and still debating what to do with it. Probably will perform some tests on it.

Not cool, Solman, snipping my statement for it to read as something I didn't say.
I did not say TP batteries were the "gold standard".
I said, "As far as I am concerned, Thunder Power is the gold standard..."
There is a big difference. I hope you can see that.

And if you had read the rest of my post,
you'd have seen that I already mentioned Glacier and EP Buddy.

Not sure what you are talking about. I never changed your quote to read "were". If you are referring to TP as being very expensive, then yes it can be the gold standard. As far as performance goes, there are many other batteries that perform just as good for a lot less money.

I have had good luck with Turnagy batteries ,nano tech with high c rating. Where it's a Hobby King item I bet none will agree with me. Almost forgot to mention Low Price can't be beat. I fly only planes.

They work ok. I am not a fan of them but do use them on occasion when I can't find a size I need.
