There is a new product we just placed on kick starter. It is a battery charging safe box that will allow you to charge inside in complete safety and it really works! I was inspired after a lipo fire in my own home. It is light weight, easy to use, effective and inexpensive. We tested it stuffed in a box of highly flammable tissue paper to prove that it truly works! Please check out Bat-Safe on Kick Starter. It may be the best purchase of the year!

just my 2 cents

I use a steel vented box and lined it with porcelain flooring tiles.

if you want this to succeed it will need battery monitoring and a way to extinguish the flames.
How about using a sensor to detect the battery swelling before they rupture? with a heat sensor
And have a it send an alert to your phone via blue tooth?
How about making a vent hose that attaches to a window ? (like they do for mobile a/c's)

or else it is just a DIY project

Charging safe box
We engineered a passive device that is light weight, portable and convenient to use. We have a flame arrestor and a filter system to cool and clean the smoke to allow it to be vented into your house with out causing damage. Hose out a window, are you for real??
Yea, a pile of bricks in your shop is a cheesy DYI project. This is a quality made device that will allow charging of lithium batteries in a safe and covenant way. Its light weight and has a handle so can also be used to transport batteries in safety. Something a pile of bricks cant do. Its also probably cheaper than your DYI project. As the efficient design helps keep cost to a minimum. If you get a chance send me a pic of your charging station. I may learn something.

I like the concept and idea. I would be a buyer but the size limit (storage). Is the only issue I have I would have to have mulitiple boxes. What are the chances of say a home version with storage only in mind. At the field charging /fire posibility isn't a real concern of mine. But storing all my lipos at home in one place is a big concern.

Bat-Safe ... remarks with an attitude aren't helpful and try to be more professional (you are venturing in the customer oriented business)

Both the Bat-Safe and Incur's idea sounds like it will work, let the customer make the choice.

I think it's a fantastic product , I do.
I would like to see prevention such as alarms before a fire happens.
something to interrupt the charge circuit.
optional venting to the exterior
check it for yourselves

My personal experience is to make the safety device super convenient and it will get used 100% of the time. This fact alone maximizes its safety. Start adding temperature sensors and additional wires to hook up and it will only get more complicated and less useful. Would you design it to have an auto cut off or just an alarm that would need to be attended?.... So many questions without good answers.

Lipo fire are rare. So a lot of complication just is not worth it. A Lipo may never go off in your entire modeling carrier. But if it does and you use this charging safe, it will not damage your house or anything else. Why do you need more than that? I have been using a prototype for years, and with the built in charger stand and wire way, I just don't charge any other place but in the box. It’s so easy. For that reason I feel 100% safe 100% of the time. It’s worth the cost of this box just for that peace of mind!

Bat-Safe,

You gotta work on your salemenship. The more I read your responses, the more it makes me think about your professionalism therefore my idea of your company.

"Sure adding items will make it complicated but not necessarily useless". If you haven't already noticed, Could there be anything be more complicated than the hobby we are in already?

May I ask, did you test it with a LiPo that produces toxic thick black smoke or just a roll of TP?

BTW I did watch your video of pretty white smoke coming out of your box.

he put the bat safe with a lipo in it (size unkown) into a box filled with toilet paper.

the toilet paper did not burn the smoke was filtered but there was allot of smoke as to be expected.

Watch at YouTube

however great this product is at containing the fire it doesn't prevent it from occurring
there are only 2 ways that I know of for a lipo to burn

1 overcharging
2 damage

amo can idea for safe charging does not work!
Guys, have had a few DIY types describe their ammo can systems they developed. They seem very proud of their setup because they add a ceramic tile to help insulate the box from the battery. Well I decided to test a ammo can setup so went down to the local Army Navy store and picked a 50 cal. box up for 20 bucks. The first thing I notice is it’s very hard to open, definitely a two hand job… Second I notice that pinching the wire in the seal would eventually damage the insulation resulting in a dead short of the battery. Anyway I dropped a 4000ma 4 cell pack in and started to overcharge. As I was doing this I started to think that I may have actually built a bomb, and started to get very worried about the safety of this experiment. If this system did not vent it would probably end up exploding. At this point I decided to keep my distance. As it turned out when the pack went off the heat and pressure significantly distorted the box ultimately leading to a breach of the seal. The jet of exhaust coming from the box was strong enough to flip the box over and off the board it was sitting on. Then there was a jet of heavy black smoke finally followed by sparks, flames and fire balls. In my estimation trapping the batteries in an ammo can actually makes the reaction more violent and forcing it thru a small passage turns this setup into something resembling a flame thrower. Possible increasing the risk of starting a fire in one’s house. I would not recommend charging in an ammo can after this experiment.

I was all set to flag this thread to complain about advertising in the wrong forum.
However, the pix of the ammo box exploding earns u a reprieve.
I am constantly amazed about the guys who use an ammo box to carry 6 to 10 LIPo around in the cars.
And somehow think it is safe.

Believe 1/2 of what you see and none of what you hear.

I posted this on another thread and also PMed OP

For What Its Worth...
To SAFELY use a container such as an ammo can or pressure cooker, you MUST remove gasget/seals and optionally drill out a few 1/2" extra holes on top. Also remove pressure valve weight to cooker.
The idea is to have a closeable lid and NOT to completely lock-tight seal them (batts).

Given the batsafe IS the way to go but for those that opt to still use an ammo box laying around, it's better than nothing.

Yes, you can add very coarse steel wool as a flame arrestor to ammo box lid where you drill holes but most dont as well as high temperature fiberglass cloth. Something already engineered into this box for a modical price when compared to DIY.

Now that the funding has been met, this post is up here for all to see.

Best of luck to OP.

Looking forward to a video where the full capacity of box (Four 6S batts) is set off.

A 4S test is not the norm for what we use. Specially with claims of the box being reussable.

This list seems a bit ridiculous. Do you want it to cost $25 or $200? Why not also mount a wireless video camera to stream the charging to your phone while you are at it? The idea behind this product was to be practical and convenient to prevent damage to an unlikely but catastrophic event. I am not paying for or going to carry around a device with heat sensors, bluetooth anything and especially hoses.? I want something I can use in my house and car that is lightweight, cheap, and will prevent major fire and smoke damage. That is what this is supposed to be.

I don't work for or make this product so I don't have to be PC.
Just because someone is in a consumer business doesn't mean they have to indulge something like this. Most of us can separate BS from a solid useful product

You're entitled to your opinion..
How much would you spend on fire prevention ??

My property is worth more than 200$

Yeah this is why I am considering one or two when it is ready but I don't think it needs --
a sensor to detect the battery swelling before they rupture? with a heat sensor
And have a it send an alert to your phone via blue tooth?
How about making a vent hose that attaches to a window ?
Those things have nothing to do with fire prevention and just add to cost, complexity, and inconvenience. I am talking about the fire that burns down your house or car not the lipo itself. If you look at his site he put it in a cardboard box full of tissue paper and set off a lipo with nothing burning or even getting singed. The trick is his vents with flame arrestors. The gasses can vent but they aren't hot and lipo fountain of fire is blocked. What more do you need? You could use a cinder block and a bag of sand but I am not putting that in and out of my car every week. It is just the simplest way to prevent a lipo from burring down your house or car that is affordable and easy to take everywhere you go.

The thing I am waiting to see is how wires are passed through. I don't want to permanently install all the wires I use. If I can slip the wires down from the top through some sort of fireproof channel on each charge I will get at least one.

It is easy to prevent fires by simply using a voltage monitor for each cell.
When a cell reaches 4.3 volts it cuts the charge cycle.
The only time you're going to have a fire is while charging if you have a malfunction.

If you look closely at the paper it is burned in the box and that was with a small 4S, can't wait to see what happens when 2 6S5000 burns

An ounce of prevention is worth 50 of theses boxes

That's why I didn't bother with this box I can make my own, if I decided it worth the time.
Otherwise prevention, prevention, prevention.
