Lithium battery

[cougar]

Anyone using one of these batteries? www.antigravitybatteries.com

 

[cougar]

Did you visit the site? These are for motorcycles.

 

[pierrelogic]

Yes,Idid and they seemed to want to talk a lot about "smart chargers" in their FAQ.

:hun:


Only 2 references to a "smart charger" on the entire web site and both were in the context of being one of several options to recharging the thing.

Without getting into an engineering discussion about the technology maybe looking at this from the perspective of maybe it could be a viable alternative. No question it is going to be lighter than the OEM Spyder battery. I saw nothing that that screamed "don't use in a Spyder." Of course I could be wrong...usually I am.

 

[pierrelogic]

:agree: They claim 4-5 year usage coupled with a 2 year warranty (pretty standard).

As far as exploding...

Can this battery explode? I've heard of Lithium exploding.
No, this type of Lithium Iron Phosphate battery does not explode like some Lithium Ion batteries used for Laptop computers or cell phones (Lipo Batteries). Lifepo4 is one of safests most stable Lithium batteries available. It is actaully considered a "green" battery. I can be discharged then disposed of with no ill effects to the enviroment like lead or other lithiums. But EXTREME care must be taken not to directly short out the battery... these batteries are extremely powerful and will melt and smoke if shorted out.

"Green battery?" Now I've heard it all.

They are coming out with a hard case version this month. I am going to try one out on my lawn tractor first.

You can not compare a normal battery to an antigravity battery. :yikes:

 

[pierrelogic]

Maybe I'm still missing something here but the battery in the Spyder RT is rated at 21 Ah where as the largest antigravity battery is 9.2 AH.

Wow..that was a quick segway to an engineering discussion wasn't it RR? :roflblack:

At least now this is being examined a little bit closer rather than trying to quickly discount the option in the first reply. My work here is done.

:yes:We now return you to your normally scheduled programming....:yes:

 

[pierrelogic]

So, now do you see something that screams not to use this in a Spyder PL?

No, do you?

 

[pierrelogic]

I would think that a 9.2 aH battery would not be a very good replacement for a 21 aH battery especially at $329.00 but that's only me.

As has been pointed out you can't compare a regular battery to an antigravity battery.

Funny...they say the exact same thing on their web page about comparing.

My point to replying was I thought you were quick to discount the whole anti-gravity idea in your second reply RR. At least now you've looked a little deeper into the details to formulate an "edumecated" opinion (you are an engineer...correct?) rather than simply implying the use of the words "smart chargers" somehow made it not a viable option for a Spyder. :lecturef_smilie:

You may have a good point about the 9.2 vs 21 aH but it took you 4 replies to get the real meat of the matter. I don't have enough time in the day to wade through that many posts to get the info I need. I've already exceeded my daily posts on here with this thread. :roflblack:

I'm just saying....

 

[clueless]

if it works and you had money to burn... would be great you could probably fit 2 batteries in the spyder and have quick disconnnects on both. then if there ever was an issue just swap the quick plug from one battery to the spare battery and bam your back in business...

this for me would more useful in the Harley where there is zero space around the battery.

my concern is not on starting but on long term draw of accessories while running....

 

[Trickie Dick]

What's the benefit?

I don't get it. I know absolutely nothing about batteries but I do know a little simple math. A $329 battery lasts 4-5 years, they say. How many regular batteries can you buy for $329? I'm still on my original battery in my 08. So I have 3 years. I may have to replace it in the next year but at $100-$140. So where are the economics? :dontknow: To save a little weight? Heck you can add that back in a heartbeat by simply picking up a 6 pack(cokes, of course) and putting them in the frunk.

:agree:3+ years on my stock battery. [never on a tender]
As far as saving weight, Every time i go on a diet my Spyder loses 15 pounds of excess weight.

 

[pierrelogic]

The $329 mentioned in this thread is for the top-of-the-line battery good for cycles that have a V-twin 1800 cc and above. 1800cc - vs - 998cc. Does that sound like apples to apples comparison. :dontknow:

It's more than just weight folks...click the link and research. I seldom if ever rely on someone else's "take" without examining the facts myself....but that's just me.

 

[Bob Denman]

Well now that you've picqued my interest you can't just pick up and leave! :shocked:

I'm always on the lookout for something with which I can get in a little trouble... The trick is to not get in so deep that the water's coming in faster than I can cuss and bail!
Is anybody going to do their diligence with these critters. I'm so ignorant about "electricicals" that I'm not even allowed to play with batteries larger than AA cells...

 

[GeoffCee]

On principle I wouldn't buy a battery with such an improbable name as Antigravity. It might turn out to be a device dreamt up by someone whose scientific education has been over-reliant on the weird science found in sci-fi comics. :joke::roflblack:

 

[effgjamis]

Antigravity.. Does that mean that my spyder can fly???

 

[GeoffCee]

An Amp-Hour (ampere-hour, Ah) is an empiricle descrpition of a battery’s capacity.
That is to say, how long it will run before it is drained down.
The amp-hour rating for a given battery is the maximum amperage that can be drawn continuously until the battery is completely discharged over a specific time period.

That's 1 amp for 9 hours, or 9 amps for one hour, or 36 amps for 15 minutes, right?

I'm thinking that the suitability of a 9 amp hour battery would be related in the first instance to the electrical drain on the battery as the starter motor cranks the Spyder into life.

As you say, BRP mounted a 21 amp hour battery in the Spyder for a reason. One reason would be to cope with massive temperature variations around the planet, wherever the Spyder is sold and used, all year round. :shocked:

 

[GeoffCee]

Antigravity.. Does that mean that my spyder can fly???

Not your whole Spyder, that's way too ambitious, but for $329 I would expect an Antigravity battery to at least hover a little... after an outlay like that my pocketbook would also be lighter than air. :roflblack:

Biggest amp draw on the Spyder, other than the starter, is the DPS. Beyond that think lights, heated grips, etc. The Spyder has a substantial parasitic load.

 

[Bob Denman]

Okay... so based on what little I know about this I should at least wait until they've got a 21 amp-hour version ready???

(wallet lighter than air... ) :clap:
