I don't know why I'm so paranoid about Lipos. I guess because I've been known to make stupid mistakes, and hate to make a stupid mistake with one of these. I finally went with the Losi one, because I figured if they burn down my house I know who to sue, but I get it, and there's this warning: "If you are not prepared to accept complete liability for the purchase and/or use of this product, you are advised to return it new and unused to place of purchase immediately"

WTF? So I'm liable just by purchasing the battery. I don't like the sound of that, and I don't feel secure with a product that has that kind of warning, so I figure, I follow their instruction explicitly, so I don't have any problems, but then the warning seems a bit extreme, so let me ask you guys a few questions and see if I'm just being paranoid.

So, I'm supposed to monitor the battery watching for swelling, and constantly checking for excessive heat. Really? I have to sit there for the whole hour just staring at my battery. I don't like the sounds of that. I've heard of filling zip lock bags with sand and sandwiching the battery between them. Should I just do that, and be done with it, or do I really have to sit and stare at the battery the whole time?

The other thing that bothered me was the storage. It is recommended that when not in use it is stored in its own plastic bag in a vented fire proof container. First off, what do I use as a fireproof container, and really? They're that unstable that if I leave it in the car, my car may spontaneously burst into flames?

Which brings me to long term storage. lets just say that for some reason my Micro-Ts get packed away, and unused for a few years. Should I just dispose of the battery at that point rather than worrying about it blowing up in my closet?


I know everyone says Lipos are much more stable now, and with proper care you'll never have a problem, but Losi doesn't seem to have as much confidence in their product, which makes me have little confidence. I am seriously ready to take this thing back, unless you guys can convince me otherwise. (Don't worry, I do not hold you guys liable for my actions. )

I don't know jack about lipo's. I still use NIMH packs for everything.
But I agree, the warning seems a bit extreme. I doubt that little thing would cause a lot of damage, though.

The planets are not in proper alignment for you to complete your purchase at this time!



I would stick 2 "D" size batteries in it and be done with the whole thing!

You guys aren't helping much.

Guess I'll have to work through this on my own.


I'm going to just keep the battery between sandbags, and keep telling myself Walmart wouldn't sell those little helis if they spontaneously combusted.

I don't think they are that dangerous. True, if used improperly (like majorly improper, sticking them into fire, etc) the could do some damage, but in any case, it's just a battery. I would think metal cased cylinders would case more damage. I've punctured one before, and it swelled, but my house is here. I charge them regularly, and it works, no fires here. Storing... I think discharging them to a safe level works. (no less than 3v mind you)

Then again, I'm also a nub with slightly more experience. Wait for ph2t or someone to show up... lol.

Uh, dude. You grew up riding in the front seat of cars with metal dashboards, no airbags, and probably rarely if ever wore seatbelt, let alone a booster seat. Were put to sleep on your stomach in a baby crib covered with bright colored lead-based paints. No childproof lids on medicine bottles, doors or cabinets. Never wore a helmet riding your bike. Talked to strangers, maybe even took candy from them. You're scared of a battery.

Either grow a pair, or get one of these. http://www.liposack.com/

Today in the news man survives all of the above only to be set on fire, Burned with acid and finally blown up by a Battery. Details at 10:00

I've blown up batteries before, and I've heard lipos have a something like a 2000 degree flame. If that's correct, that's friggen damn hot.

That's the only thing that scares me. I've blown up lots of stuff, but I'm not sure I've ever played with anything that hot.

So I guess I'll probably get one of them liposacks. Thanks for the tip.

Check out this vid. That sack looks like a worthwhile investment to me.

Ok, I would have to think that your concerns are kinda warranted.

By the way, how's your home owner's or renter's insurance? Up to date?

all those warnings are just a product of the current litigious society.

just make sure you use a proper lipo charger, don't charge more than 1C, don't over discharge each cell below 3v.

i never leave a charging lipo unattended (like heading out of the house) and once charged i disconnect it from the charger.

basically just be more careful with it than you would with a nimh pack and you should be fine.

Yeah, they ARE horrible bad and scary.
I was just giving you a hard time because my thumb hurts from installing rock claws onto beadlocks (48 screws) then pissed when I realized I swapped tread direction and have to redo half, after the blister goes away.

2,000 degrees is hotter than you can get with much other than a Kiln, Welder, or Oxy-Acetylene torch.

Get a good Lipo charger, none of this plug it into a wallwart or dumb powersupply.

As for putting out an actively venting Lipo, you'd need a Class D extinguisher, but they're really expensive and do nothing for A,B,C class fires. Bags of sand are good too. NO WATER!!!
So basically, since you only charge it on a fireproof surface, wait until it stops venting then hit anything it caught on fire with either a C or ABC extinguisher. CO2 type doesn't get that nasty powder over everything; although the powder type doesn't displace the oxygen, it's not good to breathe.

If you're not into the Liposack, you might want to look into a 30 or 50 cal ammo can from the MilSurp store (yank the waterproofing gasket) they should contain it too.

I have no insurance. The policies I looked into have like a thousand dollar deductible. I could replace most everything I own with that.

That's my beef. I don't trust mass manufacturing techniques. Either there's a hell of a lot of defective products out there, or I'm just lucky enough to get the defect nearly every time. So say the charger is defective or battery's voltage cutoff is defective, it burns my place down, I have nothing, and Losi says, "Well we're not liable for all that, but here's a replacement battery. " Then there I am sitting on a street corner trying to play the blues for money on my lipo battery. I'm not liking that scenario.


I know I'm paranoid, but I figure better safe than sorry. I think the extinguishers around here are ABC type, I'll have to look, but I had to use one once and it was the powder type.

Thanks guys, I'm thinking I'm about ready to go ahead and try this thing.

I have one, Dave, and I barely ever read directions. No problems here. I charge it with the Losi wall wart charger it came with, use it, and either leave it in the car and disconnect the cable or take it out and throw it in my Micro-T box. Don't worry about it. If it really was super dangerous just in normal use, they wouldn't sell them. I charge mine while it sits on top of our washing machine lid. The only thing that was a little disconcerting about it is it barely fits in the car and you sort of have to cram it in there past those screw posts.

I realize lipos are more sensitive than normal batteries, but ask yourself this: how many NiCads or NiHMs have you blown up due to improper charging? I think the whole worry about lipos is there's lots of idiots running around that do stupid shit like plugging it in to any old wall wart, or charging it with a charger that isn't smart, and the price for doing that with a lipo is high. I think if you just take normal precautions you'll be fine.
