Default Are Liposacks Necessary?

Hello.

I've seen a few online videos of lithium polymer battery accidents and or explosions inside a liposack. Is having a liposack only for hobbyists using various battery chargers at the airfield of does this include wall battery chargers included with rtf kits? I have a helimax ez max heli and have charged the battery in my home without a liposack and without incident. I printed off instructions for lithium polymer battery charging from rchelisite.com and an article on lipo protection which I believe in installed on my scratch n dent helimax CP-L from Tower Hobbies. My LHS has a beginners flight school for heli pilots and I'm considering signing up, on top of using my great planes flight sim for much needed practice. I think I'll need Maac insurance if I attend the flight school but I'll need to visit the hobby shop for parts and a q & a session. Thanx

If I were using Lipos I would invest in a Liposack.

I store and charge my batteries, in a large ceramic pot (in which I poured about an inch of plasterto fill the hole in the bottom) with the heavy ceramic base, the piece that's designed to catch the water, over the top. It's fairly deep, at least a foot.

No lipo sack here.

LiPo sacks are only necessary if you promise never, ever to burn your house down.

Seriously, this question is like asking if safety glasses are really necessary when operating power tools. And yes, I bought a LiPo sack.

Lipo sacks are like seat-belts.

Boy, off hand I have two cell phones, two PS3 controllers, a portable DVD player, and a Nikon D80 battery that are all LiPos. I'm going to need a lot of LiPo sacks...

I believe those are Li Ion, not LiPoly.

My new phone is Lipo as well as my laptop that Im on now.


Yep they are everywhere now days. Most of the fires came in the early days, before knowledge caught up with supply. Battery mishaps are extremely rare now days.

With all that being said I still keep all of mine in ceramic pot. Im kinda of a tard I guess, because I have so many in so many gadgets around the house.

Same here. They cost me $5 a piece. I use one to charge in, one to store in, and another to transport the batteries to the field in.

Ammo boxes are cheap and air tight. I buy 5.56 7.62 .50 in them and they are great! (getting extremely hard to find full cans after the election )

If you have an ammo box with a burning battery in it you'd better have that box on concrete.

Many years ago (decade) we had a thermal runaway on a Nicd and it literally melted its way through the box and out the bottom of the aircraft. It when through 3/8" aluminum and a steel retainer.

Haha, I use the same thing for my Lithiums cept I didn't buy mine. When I worked for the US Forest Service they cleaned out a storage area and gave me a 20mm ammo crate. I think my lithiums are safe enough in there.
