"fuse thingy" :) I came to comment similarly... not only that, but 1) batteries would more likely be near the bottom of the bags, not where they put them just so they could light it, and 2) these fuse thingies appeared somewhat inconsistent -- I would have at least tried to ensure they were as exactly the same as possible (e.g., very precisely wound, the same number and tightness of twists, and so forth).
Deez louize As I was watching this video the first thing I thought was , this fuse just isn’t burning like a lipo would . So as much as I love the fact that this gentlemen took the time to try each lipo bag , it just isn’t accurate . As I’m scrolling through the comments I noticed the video above and I read your response that the video was terrifying lol . I didn’t believe you at first , WHAT THE FK ! You weren’t lying bro , that video is scary . That 6s went off like a jet engine ! It definitely made me reconsider everything I’ve been doing with these batteries . As safe as I thought I was being . I’m being even more safe now and I’m definitely going to get a ammo box . So my batteries will be in a ZEE lipo bag a ammo box and inside my small fire safe . And I’ll be keeping them outside from now on . My shed isn’t climate controlled . But it doesn’t get to hot in the summer and it isn’t to bad in the winter . Fuck that shit lol
I'm sure that these all come out the same factory with slightly different designs and finishes with branding for the individual suppliers. In addition, a lipo fire is sustained for about 2 minutes, not 4 seconds. I don't think that any of these will handle a sustained fire.
As I said in a previous comment . I truly appreciate you guys taking the time and spending the money to test these different products . Of course the bag I got wasn’t tested though lol . That’s just my luck because I was curious to see how bags with the charging holes cut in the sides worked out . Either way , I think using the fuse was a good idea because it does simulate the flash of fire more consistent to a lipo battery going off . But I think you guys should have used more fuse . I think a fuse burning in a bag for a good 30/40 seconds or even up to a minute would have been a more comparable test to a lipo . But something tells me those bags would have been toast . There was a lot of damage done on a few of those bags with a very fast burn time . Maybe you guys can run a couple more tests with those extra bags using more fuse ? I would really like to see what a fuse burning for 30/40 seconds would do to one those bags
This is all you need... I wouldn’t ever charge a lipo inside my house anyway you should do it in the garage while keeping a eye on it. Plenty of time to kick it on to the driveway
@@definingslawek4731 I’m just a pretty paranoid person I could buy a $120 smart lipo with the hard case and I would still think it would burst into a big fire 😂😂😂 but that is true
@@definingslawek4731 Laptops and Phone batteries (By the way, almost all of them are Li-Ions, not Li-pos) are constantly monitored by safety chips on your device, specifically designed to control them and cut the power if something happens. And don't forget that the battery on your Laptop is designed and tested for your Laptop and your Laptop only. In contrast, RC batteries are "pure", the safety algorithms *should be* in the charger and the RC esc, but God knows if they are working correctly for your specific charger + battery combo, bought on Amazon from random sellers
@@kiiro712 It's very common for both laptops and phones to have lipos, multiple of my past smartphones had lipos, and the current macbook pros and airs use lipos. What do these BMS' actually do besides make sure it does not get over charged or over discharged? Which is super easy to do manually for your own batteries
They all are ejecting flames. Except the cubical one with the zipper. The most critical feature of the test would be to ensure flames are contained inside the vessel. Hobbymate all the way!!
Thank you guys I really appreciate this video - I have been wondering which was the best by now I can see that thank you so much - going to get one of the Hobby mates today
You missed the fire that shot out of the first black bag you said passed. I can't remember it's name but it was a failure not a pass. Thanks for the testing. I would rather use a metal tool box.
New lipo owner here, I respect them like any other battery. I'll keep them at a storage voltage if not using them in the next day or two. If I'm flying on the weekend I'll charge them friday night with supervision. Fire extinguisher far away/close enough. I like the idea of a lipo bag and an ammo can, too.
I have the Derblue and I swear by them. I had an 6s go off while charging and nothing but the bag was damaged. When they’re new they’re stiff once they loosen up they seal more than enough to contain any fire. But not so much that it doesn’t let smoke out.
Does that chord have it's own oxidiser? It seems like you are comparing apples to oranges. These tests would be a little more empirical if you were using LiPo batteries.
not a good test. but thank u 4 trying. batteries burn different. they can melt metal and do not behave like regular fires where water or smothering puts it out - they can sometimes burn without oxygen
I put my lipos in individual bags and keep them in a sealed metal ammo box. I put most of my faith in the metal box. I figure the bags would tame down an explosion and maybe keep one from igniting each others. I hope I never find out for sure.
I picked up an old gym locker to use as a charging station and storage “room” for my batteries. There is a lot of room inside so there is room to separate the batteries.
Perhaps I missed it, but what capacity and voltage were the batteries? In the surface RC world, it's common to see 5000mah or higher and those can destroy these bags, unfortunately.
Just due to the cost of burning up 20 or so batteries we had to do a little abstraction; we cover this at about 1:45. Rather than destroying batteries, and releasing all those toxins into the air, we used a cannon fuse analog. After some calculations we found that 6ft of cannon fuse is roughly equivalent to a 1300 mah 2-cell battery. For consistency all of these tests were conducted with a 6ft strand wrapped into a 4in bundle. We realize that with greater capacities, and more cells, there will be significantly more energy being released but felt that the cannon fuse analog we used gave us a good opportunity to see which bags held up the best. You are absolutely correct that none of these will fully contain a large capacity battery. The bad news is that these bags are marketed in such a way that many people, especially people newer to the hobby, feel that these bags will keep them completely safe. Still, it is better to have some protection than no protection and these do provide that. So how do you store your batteries? Any good advice you can provide to the community? We are planning on a round two here soon and would love to include your suggestions.
Any lipo is going to react for a much longer time at a higher temp than the fuse you tested with. Lithium stored a LOT of energy that I don’t think this test is being true to.
@@daave3 Agree, I would suggest they parallel the cannon fuse with an M-80 (standard firework). You can purchase them for testing. They used to sell them at fireworks stores. But since LIPO's can explode 3+ times or once for each cell, you need to have 3 fused M-80's that go off in about 30 second intervals along with keeping the cannon fuse going for longer. This would be a very doable test and represent the nasty LIPO flame discharge rate.
Lipo storage, large ex military rocket launch box, base lined with 2-3" sand, stood on a metal base raised off the floor slightly. Probably better stood on heat bricks but a bit unsightly in the mother-in-law's room.... !
The problem with these tests at that you didn't use actual battery packs, BUT it would've been very hard to induce a failure without inducing a failure in the bag as well, and not to mention just how expensive it would've been to destroy a bunch of perfectly good battery packs. I think a lot of the failures could be chalked up to the fuse cord being ran outside of the bags, but what else could you have done? Maybe light them and then thrown em in the bag??? Lol! Not a good idea. You could've remotely set them off. Maybe used some rocket ignitors or even used rocket motors themselves for the testing. I'd like to hear what ideas you guys spitballed before landing on the cannon fuse.
I'm seeing a lot of fire blowing out the sides so the question is - how do these tests perform in terms of duration? When a lipo blows is it over this quick? Because if a lipo blowing flares up for longer I can see it being a bigger problem
Just bought the hobbymate based on your tests. I only have nimh batteries but they are all a risk. The Apex bag was really bad. A zip looks to be a must. Thanks for all your hard work making this video, i know that must have cost you a fortune. Stay safe guys.
Thank you. after seeing this video, and seeing LiPO fires, I'm not sure their fire source is sufficient to emulate a real LiPO fire in ferocity or length of burn.
I have them inside a lipo bag and an old retired dish-washing machine! The only problem I have is direct sunlight. Temperatures rise almost up to 50 degrees Celsius in there, then.
I charge my lipos in a more expensive box type bag from AMain Hobbies. I store them in a Military Ammo can. I keep a fire extinguisher right beside the charging area and would never walk away.
I had to turn it off halfway through. No offense but I was bored picking the idea apart. For one make your pile-o-fuse sit it on your foam board and light it. Then sit a lipo off on the same board. Hmm what would the outcome be then? The fuse burns at a lower temp that the chemical reaction of the battery and the battery burns 2-10x longer. Just my 2¢. Loved that you tried and brought it up for discussion.
Thank you! I wana buy one of these soon and this is really helpful i really appreciate! These are ticking time bombs and I'm really scared of them catching fire in my house
I've heard ammo cans work great. The guy at the hobby shop told me to drill a small hole in the top for ventilation. I would think any hole would promote flames shooting out though.

Ammo cans for sure, agree remove seals in addition line the bottom with sand and seal over this with duck tape, purely to stop sand getting in your sandwiches....
I know this video is old and I apologize for posting so late but I wonder on the zipper ones like the hobbymate how much of the zipper failing is the fuse starting it melting as it burns through right there, maybe put the zipper pulls in the front under the flap?
I believe part of the purpose of the bag is to smother the fire by depletion of 02. Obviously they are 1 time usage in a failure. No matter how big the bag, 1 battery per bag or your just feeding the fire. I don't think any of the bags truly failed but then again the test was done in a very safe space, unlike real usage. What did I learn? Don't store batteries together. Use a bag but then also stick them in a metal ammo box. Lol
I have actually see one of these bags thrown on a firepit for 15 mins and the bag didn't even have a burn mark on it! However if your like me with multiple lipos and definitely sizes s I think compartments so each compartment should keep another lipo safe
rob b doubt all you want, but RU-vid’s vision for this website is that it be a giant “The Wiggles” fansite, and the further you stray from that the more they demonetize your channel and keep you from showing up in searches and in the recommended list. That’s a death spiral for small channels.
I keep my batteries in the lipo bags and those are in ammo cans. Most don't realize if you use the ammo can you need to remove the rubber seal on the lid or the can could explode due to the sudden pressure of the battery ignition.
A tip from a fireworker: The less space the fuse has, the faster it burns. In the flat bags, the fuse burns practically like a covered stoppine. (all at once) I don't think you can make any representative statements about the bags in this way. A very small fountain would probably have been more meaningful.
More than one battery in a bag when it goes off what would happen just like everybody else even though you propped you know you shouldn't overfill your bag a lot of us still do so will it hold up to a couple batteries going off I really highly doubt that would be awesome if you could do that on some of the oppressing bags at did a good job with just one thank you guys for all your content I enjoy watching you guys
I like destructive testing. I would like to see this experiment done in the dark. That would be more interesting seeing how big the flames are shooting out of those bags.
I just had a LIPO cell phone battery swell and ignite in my had after I took it off the carger that it came with (Batt only not in phone). It burns like a bucket of sparklers going off with lots of flame. It also burns for longer and growing in intensity than your fuse test. I'm not sure that any of these bags would actually hold up to a battery fire. Wow. I tried to stop the fire out since it caught my carpet on fire and it burned thru my shoe and I have 3rd degree burns on my toes with blackened burnt skin and skin that is falling off. VERY painful. I'm wondering if it was burned from flame or chemical. I have unplugged every battery tonight and looking for solutions that are safer I'm not sure these bags will hold up.
They have another one on Amazon with a zipper AND the pouch velcro in front. That way if the zipper fails at least the velcro should keep everything shut for enough time.
You liked the apex bag but it had flames coming out the sides .same as the bag after it and you pointed that out and didn't like it ??. And one bag shot a cunk of flame into the hedge by your camera. And you liked it .
The way these 2 guys talk to each other reminds me of the 2 guys near the beginning of Friday The 13th part 6 (Jason Lives) who were playing paint ball. If you want a laugh check that scene out! Anyway, very interesting video.
Seems that Velcro consistently didn't hold up (the stitching) and my first thought on this is that perhaps the thread used for this stitching was nylon? Velcro being a thicker material for sewing, generally regular thread is not used. While I think any stitching material will probably not hold up, nylon is going to burn easily.
Would it be possible to store your Lipo in a Safety Bag that you put in a Metal box with Hepa Air Filters on the air exists so that if the LiPo explodes the safety bag prevents fire and the filters prevent your house from getting smoked up entirely?
Even if flames are contained, you still have highly toxic fumes bellowing out. I read you can get pulmonary oedema from them. One can run away to another room until the smoke has dispersed course, or try to quickly toss the LiPo container out. But will the smell go away at all afterwards? Or is the room where the "incident" happened doomed to be smokedamaged for ever?
It may be a bit extreme but for something that isn't hobby grade or lipo specific, try a small safe that's fireproof. Good thing with the good cheap fireproof safes is that it won't engulf if you keep it locked so that should be a nice alternative (small ones are portable anyways)
The APEX Bag you said Exceeded your expectations was one of the worst as it was a Flame Thrower❗It did not contain the flames therefore it Failed. The Hobby Mate was my choice it did an outstanding job & No flames outside the bag or damage to it. These tests you did may replicate only 1 lipo battery but no tests were conducted for multiple batteries. What are the possibilities of one lipo igniting others stored in a bag with it.❓ THANKS FOR THE REVIEW👍👍 ❤
Flame shooting out the side I think is purely chance of where the fuse is placed and the weakest point/closest opening. Burning of these types of batteries causes the rapid release of gas... it has to go somewhere, if it stays sealed, pressure builds and that can cause as explosion. I'd rather a 1 second flash to the sides than consistent burning through the bottom.
this dont make sence because ur fuse only has a flame for like what 7 seconds a lipo battery fire would last like 2 minutes so next time try a real TEST!
Seems like the bags with the inner flaps prevent the sparks and initial burst from finding the easy way out. Id be curious to see how likely it is when the bags that dont seal completely up top, eject enough heat to set sawdust or newspaper alight. And not for nothing but just an observation for the envelope style tests failing at the zippers. You in effect have heated that area twice with the fuse and then the explosion. Id imagine you compromised the stitches going in, and blew them out while still hot. I wonder if you might have a more comprehensive result if you triggered the failure from inside only. Thanks for the testing regardless, im a new hobbyist and an old man that had NO idea these batteries were capable of catastrophic failure like this. I kept my batteries in a wooden cabinet with paints and solvents out in the garage and didn’t give it a second thought until I happened across a suggested purchase while looking for rc parts on Amazon, and then found this post. Again thanks for the information and the testing..subbed
If you have multiple batteries in one bag they all will probably catch on fire if one battery lights up. So idk if this test would simulate real world scenarios unless a person had 1 battey in the bag
Be sure to charge and store lipos in seperate bags so if one explodes none of the others do. So inspect your batteries before use and be sure to despose of of them properly so you dont start a potential forest fore fr it being in a landfill then getting ran over by a bulldozer. Also last thing you want is to be on an airsoft field ghen your gun mysteryously stops functioning then it stats smoking/exploding.
The test is skewed, in a way. Because when using a large bag like the Hobbymate, that lightweight burning wire isn't being pushed tight against the bag wall. The wire can move freely inside, spreading the fire around instead of concentrating it to one spot. That said, you probably still want a big cube-shaped bag, just like that Hobbymate. Why? Because it directs the fire upwards, away from the surface it's standing on. With the envelope shaped bags the fire will shoot out the side directly onto the surface it's resting on, or any flammable items nearby. Bags like the Hobbymate is also large enough so that you can place something in the bottom of it that nothing can burn a hole through.
