Neat! So if it explodes, the fire will burn for no more than one hour.
(lol, sorry... couldn't resist)
While the placebo effect is real at least when it comes to humans, I don't think it has any effect on fire. I think you'd be safer in reality by using a hobby charger, with the temperature probe monitoring the cells, and a reasonable time limit & capacity limit programmed into the charger.
Now you got me laughing! This from the guy who doesn’t mind blowing up emitters, in the name of science
You know how human nature is, one can work themselves up about just about anything.
I recently heard a discussion on the radio about dangerous activities and risk. He said it is not the occasional high risk activity that gets us, but the frequent low risk activities. For example in the U.S. each year about 42 people die in skiing accidents, but 6000 die of falls in the home. Infrequent high risk, vs frequent low risk.
Then there is the irrational fear of flying for instance. There are fewer deaths per passenger mile in planes that cars, yet some people have a fear of flying.
Not being complacent about charging cells goes along way in protecting oneself.
Just be sure you're realistic about the amount of security you get from the timer setup... yes it does protect against some things, but it's not comprehensive. A false sense of security is a terribly dangerous thing.
Kudos to your coming up with very neat, elaborate system for safe charging! The drawback with that is I am not that handy in putting up the gizmo you made, and I am not that paranoid about LI blowing up. I may show to a friend in making one for me.
(One thing I don’t like about the LIPO bag is that heat is not being dissipated.)
I have developed the perfect solution. I have empowered my neighbor by teaching him how to charge all my batteries and store them for me. Now I never worry about explosions or fires any more. When I need cells, I just go to my neighbor and he makes me sign them out. He feels so much better since he has responsibility and I feel so much safer...
It is better to just have the cells in the lipo bag. Particularly AC li-ion chargers can get warm or hot. Some nice thermal images. 18650 holder. People have gutted cheap $1.50 chargers to use as adjusted holders too.
In CT, with CLP rates being about the highest in the country, it only makes sense to be as energy efficient (and safe!) as possible… I like the set up.
Been using a heavy duty outdoor timer and put my Nitecore chargers and cells into an old large metal pot on the concrete floor at home (and/or work) if I am going to leave for any period of time…just feel safer that way.
What has really freaked me out is that I recently got the highly regarded MAHA C9000 for my Duraloops. I noticed that on some of my older cells, the charger would miss the cutoff voltage and pump 4000-5000mAh into a cell now and then. This is charging at 1/2C of the original capacity. I presume the reason being that the cell was faulty and didn’t charge up to the cutoff voltage. Any good cell could eventually become faulty and do the same thing. If something like that we’re to happen with a Li-ion there could be a big problem.
NiCad and NiMh chargers for the general public are usually just timed charges at a low rate. To me that was a clue that a timed charge was determined to be safer, in general, than cutoff voltage. So why not combine the two?
Now put the whole affair on top of a distant mountain and wait!
Total safety!
(Works for me! Except for the distant mountain bit. Our mountains were worn down to nubs long ago! It also works on an island in a lake, which may be even more safe as the dreaded “vent with flames” would be contained by the lake water…)
Was that bag actually fiberglass…? Looks like it just burned. Haven’t read through all the video comments and answers yet.
Thanks for posting! Was worried some bags might be crap since chinese sellers seem to turn everything into fire hazards.
