Yup, RC pilots are all electrical engineers and well versed on thermal loading and capacitive discharge rates per square inch.
Us poor dumb consumers are ignorant to all that high tech stuff that RC modelers are experts on.
Not to mention all those ignorant bio-med designers that have used Lithium ion batteries in medical implants for years.
Medical device manufactures don't care what they implant into people. It's all about the money right? They don't care about liability issues or recalls or unsafe products. Yea , Right.
I'll be sure to tell them to get their designs approved by the local RC chapter and do an internet search before they apply for a 510k approval.
The only exploding that's happening with lithium batteries in this millennium are their new applications and sales.
Lead acid batteries still continue to explode. A hydrogen explosion, sulfuric acid exposure and subsequent electrical fire is no less catastrophic than a thermal runaway with an old style Li battery.

Glad to know you've got the MA370 disappearance figured out. I guess when the "road flares" ignited it completely incinerated all traces of the aircraft before it hit the water. And here I thought it was the grassy knoll gunman again.
I figure I wasted all those years working for Ford Motor Company as an electrical / applications engineer. Good thing I went into the medical field and left all that complex electrical design work to the RC modelers.
Maybe Boeing should hire a bunch.

Take off the tinfoil hat, put down the glass pipe and go to bed.

A rather ironic and sophomoric comment from Chicken Little running around wailing that the sky is falling.
More precisely, that aircraft are falling from the skies in flames from road flares and that our battery packs are time bombs waiting to explode.

Perhaps even more ironic is the current (pun intended) crop of electric aircraft all use Lithium ion batteries.

There are literally billions of lithium ion batteries in use today. They are no documented failure rates that exceed any other type of battery.
With the possible sole exception of some laptop batteries in the nineties.
No modern battery manufacturer recommends any of the charging or storage precautions you warn us about. Just the usual advice that accompanies all storage batteries.
A quick perusal of legitimate research sites offer no cautionary advice beyond what one would take with any electrical storage device.

Actually most of the concerns are that we may not be able to sustain the rapid market growth due to supply issues.
Hardly the harbinger of injury and death that you would have us believe.

The Anti Gravity battery, and most other newer generation lithium ion batteries are in fact a different technology and a different chemical makeup. They are Lithium Iron Phosphate (LiPO) batteries. The lithium Iron Phosphate batteries have not demonstrated thermal runaway. They are a MUCH safer battery, and by all accounts, they are every bit as safe if not safer than a lead acid battery.

Not trying to nit pick, but Lithium Iron Phosphate is LiFePO4, Lithium Polymer is LiPO. There is a significant safety difference between the 2.

Okay, my bad.....call it what you like in abbreviated form. Lithium Iron Phosphate is what I was talking about.

MTV

That's not nit picking, Thanks for setting me straight, I stand corrected. There is a significant safety difference between the two. Very interesting battery.

Had a chance to field test my Antigravity Micro Start XP-1 Battery this past week. Friend left his master on in his CarbonCub. Hooked up the Antigravity and it cranked the CarbonCub just fine - three times as a matter of fact before he started it. Got home and plugged it in for a recharge and just one of five leds was blinking. Pretty cool and doesn't weigh hardly anything.

I carry the XP-10 in the plane. Already used it once to jump start my car after I killed the battery one day. Amazing product.

Well, I have some followup on this product since my last post.

I pulled it out of my plane last week to charge up my iPhone and found that the unit had expanded from within and blew open the case. It made me a bit nervous frankly to see this battery looking like it was going to explode. Furthermore, the unit was not working and I was unable to charge my phone (I thought I would try it anyway).



So I decided to email the company about this issue. I sent them the above photo. No reply after several days. Then I called the number on the website. No answer. Not sure what is going on with the company or my XP-10, but I don't think I can recommend this product to anyone until I get this sorted out.

Looks like the magic smoke is ready to leave the box. Discharged too far or charged too fast.

It's just bursting with power, impressive [emoji12]

But seriously, let us know, I've been waiting to see how these shake out before bitin the bullet...

I've had really good luck with my micro start. If you stay on top of keeping it charged properly I think it's a great tool. I've started a handful of small planes and it did great. It's So much better than the old school battery pacs they would sell that are ten times bigger and never hold a charge and work when you need them.

Are these things still the thing to buy for jump starting planes in the middle of nowhere? Looking to purchase something for O-360. Was looking at this and the EarthX variant. Leaning towards the XP10

Thanks

For reference, looking at these two based on BCP threads:

My old one finally quit holding a charge.
I need to purchase another one, these look good.

I'm using the Earth-X jump-start pack. It has been excellent so far, along with the Earth-X 900 in the PA-12.

I'm heading south to Yellowknife in a couple of days and have to leave my truck at the CYCO airport where there are no plug-ins. It's supposed to be -30C or colder for several days before I return home. I'll be taking my jump-start pack with me (rather than leave it in a cold truck). I'll probably need it, and I'm sure it will work just fine.

Excellent customer service from Earth-X by the way.

The specs on the XP10 seem better, but I can't find any negative comments on the EarthX and it seems more widespread in the aviation community. Also, it's $50 cheaper.

I've got a couple of the noco units. They work great on my pickup, and stay charged for a year, but I've never tried it on a plane

I've used mine on aircraft a few times. Worked great every time.

Earth X all the way! Why buy from an outfit that DOESN'T also sell a line of aviation specific batteries? I prefer to support X, as I love my X plane battery so much.

I've used the Anti Gravity micro-start on my Toyota with a completely dead battery. Worked fine. Also use it to charge radios and ipad in the field...works fine.

Never used it on the airplane. Easier to just hand-prop IMO.
