Default Anyone notice.......?

Anyone notice the front cover of this months AMA magazine. It's an Electric Flight issue and on the front cover it shows several examples of new electric flight technology except for.............Li-PO batteries. The batteries are plain old Ni-Cd. It a suttle way they are showing that the AMA doesn't like Li-Po's. Interesting.

Just you watch, now there will be rule #10 stating "Thou shall not use Li-Poly" in the AMA Bible.

When you charge/use your Ipod, cell phone, laptop, etc, do you worry about it exploding into a firey plume of molten lithium? JK, But it's true. Li-Ion and Li-Poly are used nowadays.

The DVD they sent me hoping for a purchase had a very detailed and informative discussion about Lipos. Naw, I don't think there is any subliminal message there.

Good observation RC sport. I hadn't noticed that, but you may be on to something.

Li-Po and Li-Ion batteries in things like cell phones come with circuits that closely monitor the battery and prevent over charging and such. If we did that, we'd not have problem.

But it costs money, and reduces flexibility and innovation in what we do. The batteries aren't the problem, the way we use them is the problem. I think the AMA actually does get that.

It wouldn't surprise me, if a few years down the road, there is some kind of industry standard and requirements from the AMA to only use the correct bits together in approved packages. That would make it as safe as a cell phone.

Speaking of cellphones, Nokia now recommends that if you drop your cell phone on pavement or a hard surface, you should leave it on the ground for a few minits before picking it up. Just in case. It seems that some batteries, espeically "counterfit" ones that aren't up to spec, can, and have, caught fire after taking a shock. Interesting, eh?

Right on, Kirk. Too bad the guys that started using them in model airplanes removed the PCMs (Protective Circuit Modules), else as you say we'd not have the problem.

Fortunately, some suppliers like Fred Marks and Shulman (PolyQuest) are putting them back in the charge circuit. They aren't free, but at under 15 bucks they're a good deal cheaper than the batteries they protect, and an investment we need to make to polish up the tarnished reputation of LiPo technology in our models.

Mind you, I actually support being able to hack around and try new things. But people need to know the risks they are taking when they run a Li-Po or Li-Ion with out a safety. If they are wreckless and start a fire, that shouldn't be blamed on the battery chemestry or the manufacturer of the battery or charger. But unfortunatly our tort system can be a bit wacky.
