Look, the simple matter is safety is the primary concern, no matter what batteries you're using. Don't be stupid, and just because you haven't seen it doesn't mean it can't happen.

I'm curious, how many of you have used a Dremel tool without safety glasses?
A lot.

But, I also wear regular eye glasses

My two cents on the matter. I have never seen any type of battery go boom. I have melted a couple, but never an expolsion. That doesn't mean it doesn't happen, but accidents happen when A PERSON does something stupid.

Don't blame the battery, blame the person using it.

Maybe one of you could invent an idiot proof charger. I have tried and someone keeps inventing a better idiot.

Ain't that the truth...

And just the other night actually (at a race i wasn't at) a lipo exploded (was charged in nimh mode) just as i typed what i previously typed. Oh well. Things happen, more "things" happen if you are being stupid.

I have seen one first hand battery explode, a 12v car battery. It was frozen and an idiot jumped the car, almost ripped the hood off the car.

There is so much energy stored in batteries and the reason you hear these fantastic stories is we are a long way from 1200 cells. More energy in the cell means more room for holy cow type failures.

It is pretty simple charge and discharge any battery as it is supose to be and your chances of problems go down a great deal.

i dont feel safer using a lipo sack, but i agree that they should be a mandatory item when charging lipos at the track etc...

i have only had one nimh pack vent on me..

at the end of race i was walking back to pit lane when i noticed a smoke cloud coming from my car.. i quickly got the car and took it outside with just enough time to scramble and get the pack out and into a safer area away from people before it went boom! (2 cells exploded, 1 cell burst along the seam and the others sizzled and smoked for at least 15mins afterwards)..

i'm happy for you to do whatever at your home, but when you're sitting all around me charging your unbalanced nimh packs at high amperages i'd much rather that there was some sort of protection..

long story short..

precautions should be mandatory for ALL battery types, be it a charging bunker for nimh or a lipo sack for lipos..

(also dont forget insurance requirements when you're forced to use lipo sacks)

Anyone want to sacrifice a nimh pack and an ammo box to see what happens?
same results as a bullet cooking off.

Good to know

Should handle any LiPo charge problems as well!
