|

I am considering producing state-of-the art, very lightweight, ultra
long life, starting batteries for experimental aircraft. They won't
be cheap to make, however. I'd like to get some feedback as to the
market for these before I put a big effort into this.
Here are the specs:
14 volts
480 cranking amps
8.8 amp-hours
2.7 pounds (Yes, really just 2.7 pounds.)
10 year warrantee (prorated)
Completely sealed battery
Safer than lead acid or NiCad
Built-in electronic monitoring system warns of over-voltage,
under-voltage, over heating, or internal battery fault.
That is all the good news. The downside is that they will cost about
$475. I'm not sure how many folks would want a 10 year battery (at
least) that weighs about 1/3 as much as an "ordinary" battery, but
costs four times as much.
The specs above are real. I have personally tested these batteries
and they do, indeed, perform this well, so that is not an issue. I
know I can make these. I'm going to make one for myself. The question
is, will folks buy them if I more of them?
Let me know if you think you would be interested in such a high-tech
battery at this cost.

I find your claims a bit hard to believe. The only battery chemistry, I
know of, that can put that many watt hours in that light of a package
are lithium polymer. The price sounds about right for a lithium polymer
battery that size too. I don't know for sure if you can pull that many
amps from a lithium polymer battery, but I do know they are no where
near as safe as SLA or NiCads. There is no way I would put that big of
a lithium polymer battery in a plane I am flying in. I have seen way
too many electric model airplanes blown up or burned down to trust a
lithium polymer in a real plane. If your not talking about lithium
polymer, what is the battery chemistry? Your not going to keep it a
secret for long anyway.

Bill,
You didn't mention size or shape. I'm building an auto
conversion, so for me the main issues are amp-hours,
size, weight, and degradation. Not sure if degradation
is the right term, but what I mean is - will the battery
still have 8.8 amp-hours in 2 years when I need it?
In 7 years?
Also, a way to know exactly how much juice is left in
the battery at any particular moment would be great
for my application. It's as important as a fuel gauge
when the alternator fails.

Hi Bill,
Sounds like Lithium Ion or Polymer to me. If it is, I would have extreme concerns as to what the safety measures would be insure no fire or explosion.
Being heavy into RC with several LiPo powered electrics and helicopters, I can tell you these batteries are nowhere near safe. I only charge these batteries when I'm monitoring them. Additionally, I charge them in a deal called a "battery bunker" which is like a small SWAT team containment can in the event of over heating and/or explosion.
I have had 2 friends have their vechicles burn to the ground while charging these batteries. They cannot handle ANY over charging at all. One exploded when only being charged at .5 its rated amperage. Normal charge is 1:1.
I commend your ingenuity but this may be a tough sell. Maybe after you put one in your plane and fly it a few hundred hours they may gain some acceptance. In the mean time $475 equates to 7 Odyssey batteries.

Bill, I've got several aircraft that I would put them in " if " they were SAFE and you could keep the price under $500. I echo others' concern on the technology being safe.

Hmm yes, there is a video clip at
http://www.helihobby.com/videos/*LithiumBattery*.*wmv* showing the
effects of an overcharged Lithium Ion battery. Now i believe this
battery was intentionally overcharged, but.... the pyro at the end is
still impressive.
As a forensics person i have seen my share of Li-Ion batteries which
caused fire or harm, plenty recalls for especially aftermarket camera
and cellphone batteries going around.

Safety is not an issue. That is why they are so expensive.
The specs are real. I have personally tested them myself.
Would you pay $475 for such a battery?

The internal electronics will tell you when you are near the
end of the capacity. You could test the capacity using that feature
during your annual, for example, to track the battery performance.
If you want a actual battery fuel gauge, it would be extra.
It isn't hard to do, but it requires a lot more electronic hardware.
You can buy one commercially for your present battery if you want to.
They are called a Link-10. Boats, RVs (the other kind), fork lifts,
and electric cars use them.
http://www.energyoutfitters.com/default.htm?http://www.energyoutfitters.com/products/p_m_electronics/xantrex_link10.shtm
They are pricey, but work very well. They are very
lightweight. I plan to install one in my RV (since I have an
electronic ignition and EFI.)

If such a battery does really exist I am sure people would pay for it.
Especially those in the electric RC plane hobby. However you have not
yet convinced me that a battery that meets all the criteria in your OP
exists. The links above mention nothing about such a battery, at least
if they don't I can't find it. I don't mean any disrespect, but I am
not going to take the word of someone on a message board about something
with out any evidence to back it up. I also don't think you will get a
lot of response to your query until proof that such a battery does exist
and can do what you say.

So, I guess you won't be my first customer.
I have quite a few of these earmarked for my electric drag bike.
http://www.KillaCycle.com
If all goes well, they will be in the bike and we'll be at
Route 66 drag strip in Joliet on May 13th. I'll keep the list posted
on this. You will know the brand when the bike appears at the track.
Ultra-high-power state-of-the-art batteries is what electric
drag racing is all about. I have my finger on the pulse of battery
technology, naturally. I test a lot of batteries to see if they
really meet the manufacturer's specifications and put out the power
that I need to race the bike. I torture them on the bench to see just
how far I can push them on the track.
In addition to being ideal for my drag bike, these
particular batteries are also very well suited for aircraft. This is
because they are as safe, or safer, than lead-acid batteries. They
cost a fortune, however. Cost is not an issue for setting world
records, but matters to some folks that are building airplanes. It
matters not to other folks building airplanes. No doubt, you will see
these exact batteries in military aircraft in the next year or so.
Commercial aircraft will have them a few years later.
I'm not trying to sell these to you now, so there is no need
to prove that they meet specs now. I'm just trying to find out how
many folks will pay $475 for a very high-performance, safe,
lightweight battery for their homebuilt airplane.
If it does everything I say it does, would you pay $475 for
one? Yes or no? I'm not requesting a commitment or any money. Just
tell me if you would honestly consider buying one if I prove they
really are as good as I say they are.

Bill, I might not be your first customer; but if the specs you list are accurate and she is safe... "Yes" I will buy one. Heck if I like that one, I'll buy more. Anytime I can shed some pounds in one of my aircraft and keep the same performance (or better as you state), then I will cough-up the extra $ to dump the lbs.

if they don't I can't find it. I don't mean any disrespect, but I am
not going to take the word of someone on a message board about something
with out any evidence to back it up. I also don't think you will get a
lot of response to your query until proof that such a battery does exist
and can do what you say.
