That's only one battery. Could you imagine having 10 others pilled with the one that ignited? Wow, it would burn 10 times the amount you have there. With that bing said... its probably smart to only have a few Lipos per bag rather then pilling them up. The bags are not expensive, so having 4 bags for say 10 batteries might be safer.
Batteries mostly only start on fire when being charged or discharged (or damaged). So for storage purpose, I dont see a big deal with piling multiple batteries in a bag. I do agree that you should not be putting a parallel charger in one of these bags connected to many batteries. I do have 4 bags. I have 8 1500 4s, and 20 500mah 2/3s. I might purchase another just for the cheapness of the extra safety
we RC hobbyist have known back in mid 2000s that the no.1 cause of lipo fire is "overcharging" ... that is why it is imperative to use a very good charger... the best way to put out the fire is "sands" ... lots of sands! so stock a bag of sands in the house... do not use water, it will not extinguish the fire... no. 2 cause of lipos fires is after a crash of your RC plane or car since the lipos might be damage... disconnect the battery immediately after a crash and bring the lipos in a safe place... the lipo batt. need to be observe atleast 24hrs minimum. after a crash in a safe place... then double check the condition of your battery before charging and during charging and away from your house if possible or in a safe lipo bunker...
Great demonstration. These are on my purchase list. Does HobbyMate happen to make individual Lipo batter bags of the same material that I can store and charge Lipos in so they can be double bagged? My thought is I might charge or store 2 or 4 batteries in each HobbyMate bag double bagged so that one battery doesn't cause the other 1 or 3 batteries to catch on fire also. In case you haven't guessed I'm an Engineer with a Safety Analysis background. Two layers of protection is always recommended to mitigate accidents.
This is a nice test though I'd like to see someone do a test with a parallel charge board with 4 6S batteries going simultaneously. That's what I'm typically charging up at a time. Guessing bad wouldn't hold but am curious how bad it would be.
I moved to ammo cans after I had a charger malfunction and start the lipo on fire. It recognized it as a 4S battery when it was a 3S. What a mess. I'm always in the room when charging, so I was able to minimize any damage, but I quickly learned my lesson that those bags are an absolute joke and will not protect you from anything.
So what happens when you have those 15 batteries stored in that little space and 1 damaged battery catches fire? Can it contain the flames from all of them burning at once? This bag does an awesome job to say the least at containing the flames from a single 3s. But if that 3s is stored with many more batteries when it catches fire, the rest are most likely gonna go up in flames with it. Awesome bag. Just don’t recommend charging or even storing multiple lipos in one confined space.
Good way to destroy 15 batteries and defeat the whole purpose of the lipo bag being that bag is fucked if 1 vents....Could you imagine all 15 lipos giving in Lmfao. 1 lipo destroyed the bag lol
Exactly. What happens when several Lipo batteries are inside and one or more batteries ignite? Wondering if the Hobbymate can still contain a fire. Nevertheless, it does appear to contain a fire with one battery.
Joshua, I have designed a lipo bag that can contain explosions from multiple batteries. See link. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LGlnDHsT8es.html
My whole concern with these isn’t that it can’t handle 1 battery, it’s can it handle 1 battery PLUS the other batteries that may explode as a result? I have a BatSafe which I will use to charge in and to store two of my 3S LiPos in, but my smaller batteries will be fine in here. Again though my concern is if one goes up and blows up the others. Not sure they’re rated for 6 simultaneous flameouts!
Maybe each battery has its own bag. If one bat went bad in a bag full then they all go bang. I'd like to see the bag hold up to that domino effect. If anything storing a big bag full of lipo is more dangerous than storing them separated in my opinion.
Yeesh! I'd better get my outdoor pizza oven built to store my batteries in. Way too many lipos. The amount of smoke damage that would do to your house would be disastrous. Or in my garage my F150, CRV, Jetski, full gun safe, freezer full of food, tools, etc etc would be ruined. Yikes. You'd never get the smell off the walls and garage doors. Thanks for the video. I need to rethink some stuff.
Granted it was only for 1 bag, a way better review & test than what was conducted by Angry Zeppelin since it was conducted using an actual battery, and not a 5s burn cannon fuse, which is really not the way to go about testing something as dangerous as a lipo battery.....
Well I guess they thy make different quality lipo safety bags. When I first got into the hobby about 3-4yrs ago, I was stupid/ignorant and made the big mistake of doing zero research on lipos or chargers, Bought a cheapo $25 dollar charger, and a couple no name brand lipo safety bags. I figured the bags were all the same and had to be made out of regulation type material. My first racer was a rtf kit, from a youtube guy, who sells his builds. He used to use his balance plug from battery to power vtx, so i thought that was the norm, and the only reason for that white plug coming off battery. So I was balance charging 4s 1300mah batteries without hooking up balance plug, charger was so cheap, it didn't give any warning. One day was charging up brand new Tattu and about 10min in I heard it popping and buzzing. Luckily I was home, but before I could get to it and unplug, it popped super loud and caught on fire. It was on a plastic table in finished basement, in a lipo bag. Well let me tell ya, I've been a firefighter for almost 25yrs, and I have never seen something that size not only break out into a full fire so quick, but the intensity of the fire and how hot it burned was amazing. It burned through the lipo bag in about 10sec, lcaught drywall and carpet on fire within seconds, melted corner of table, charger and another nearby drone A large 32oz tumbler full of water and half of large Starbucks Ice coffee didn't even put a dent in it..LoL. Luckily my gf finally found the fire extinguisher and got it out. Then had to go air out the house, change my boxers and go have a couple beers to calm down. Best advice I can give, get a b\attery bunker, you buy them affordably or there's a bunch of DIY ones here on youtbe you can make for cheap. Mines a $20 metal ammo can, with small hole drilled in side for wires to run though, have small rack/lid thing on top that holds a small bag of sand. This is all in my unfinished laundry room with concrete walls a concrete workbench.
i was surprised you are a fire fighter and doesn't know much about lipos.. i have been using lipos since mid 2000s and the only way to put the fire out is lots of sand and or a special fire extinguisher that uses a special chemicals back then... and still apply today...
@@yurstruly9485 Trust me, I know more about Lipos than you, it was an instance of over confidence and not doing proper research into a niche part of the lipo technology, which is why I post in forums about it, in hopes that others won't make the same mistake. You are posting false information right here, so don't be so quick to act all high n mighty. A hobby grade/size RC lipo can easily be put out with water, in fact water helps cool the tabs and few bits of actual lithium metal in a Lipo, cooling them, stopping the process of thermal runaway, which is the main chemical reaction happening during a lipo battery failure. The number 1 cause of Lipo battery fires IS NOT overcharging, it is over discharging, getting the a cell well below the recommended 3.0v. With today's chargers, and quality control done on Lipo batteries, overcharging rarely causes a fire, or even bloating. The preferred, extinguishing agent would be dry chem, found in the common ABC extinguisher, CO2 extinguishers will also work, as will water extinguishers. Larger industrial sized batteries containing Lithium have a much larger percent of actual metal Lithium pieces, which, like magnesium, burn extremely hot and react violently to water, those fires you will need a special extinguishing agent, such as AFF Foam.
Yes just for storage reasons. Better to be safe than sorry. A damaged battery or compromised battery you dont know about can be a contributor. But dont be scared by lipos. You have to realise a lot of batteries used commonly are lithium now a days. Being new myself I see the batteries we use are used and abused more than most so the risk is slightly higher. Just charging properly and keeping a storage charge on em will go long way in eliminating 99% of the hazards. Dont be put off by the lipo battery fire videos. Just inspect batteries cases and wraps regularly is the best advice I can give. You'll be good to go
All that smoke is going to cause damage anywhere indoors. So one might prefer the porch, garage, or even better - in your BBQ grill in the back yard. :)
If lipos are so dangerous. Why would anyome want to risk burnimg down their house ? All the memories/stuff in your house . Would the nickel metal hydride batterys be better . If you dont race ?
I don’t care who makes the bag I would never store more than a couple together. No way any bag will stop one of those going off with 6-20 more next to it in the bag... A lighter is nothing compared to the intensity of a battery fire...
Hmm seems this bag can take at least double this damage by once, i mean 8200mah one battery or 2 batteries of 4200mah each. I speak theoretical always. Only tests can prove this. As i see this bag make a very perfect job for at least one fully charged battery of this level. The best part is that the fire hold for not much time, but the smoke did very good job. Imagine this amount of smoke to stay in a small room and you are out for coffee. Guys i believe don't carry or charge more than two batteries in one good quality bag. I never charge lipos without watching them. If i want to go out, i always disconnect the battery from the charger, and i connect again the batteries when i come home. Even for a few minutes if i go out just to buy a pack of cigarettes and come back, i disconnect the batteries from the charger. If you do that you will be safe for ever.
