Flite Test - Lipo Battery Bunker

[@StereodreieckRC]

I use the balance program everytime.

[@mauricioalves8860]

Well, personally, I think that the best lipo bunker is something like an Outdoor Barrel Charcoal Grill with Side Table and wheels (that costs less than a hundred bucks). And the key word here is outdoor, outside - or at least, a balcony. Another important aspect is that you will have fire and smoke isolation (by just closing the barrel), because you can choose to place the grill with nothing nearby... you can open and close the barrel... and some even have a small chimney that will direct the smoke (that you can add more tubes to make the smoke go much higher). Definitely you guys should try that out and perhaps make a good video about this option, putting some old lipos on fire to see the results.

[@Trainedn00bdotcom]

I love the idea of sticking them into the cinder block holes with the sandbag over it. If one battery goes up in flames the rest won't! I love it, still a great idea with the battery bunker Josh! I also use the ammo boxes for tools, electronics and food! They are watertight and can take a beating. Thanks for the video guys, keep it up!

[@MrDan1713]

In the case of ammo cans, lining them with cement board will insulate the metal can so it will be less likely to transfer heat to the surrounding area.

[@chuckworley3096]

As usual a great video. I had my lipo battery bunker built into my house. Now that all of the children have graduated collage and left home I took over the family room. The family room has a fire place with tempered glass doors. I just put my battery in a charging bag, place the bag and charger in the fireplace and close the doors. I have a fire extinguisher handy, but I think I’m going to put a bucket of sand close by as well. Thanks

Safety is no accident.

[@nateberry9393]

you got that right

[@wallabyrob]

Thanks for making this hobby safer for us . I really appreciate the learning curve you guys provide. Cheers. Oh, and if Dan Wilson doesn't condone your language please know that many of us do.

[@cha3119]

Extra good video. Please keep this topic active, creating occasional safety videos. The risk of having lipos in my home really sunk in a while back and I don't believe enough is done to help the flyer keep this in mind. Especially if you fly nitro, too and all your materials are kept together. A lipo explodes and your nitro goes up as well - keep them separate.The idea of putting the bag of sand above the concrete block pocket is excellent, maybe better than the concrete board on top. Thanks, keep up the great info!

[@SYNFPVPILOT]

Great tips and love the bunker idea. A friend had a spontaneous lipo fire this weekend on a camping trip that could have cost him his car or worse if he was driving. The lipo was old and sitting idle in a gym bag with others. One cell decided to party. If I didn't see it I wouldn't believe it could happen like that.

[@abdumalikmustapha4689]

[@zfotoguy71]

Great safety video! Everyone in the hobby should watch this, especially those who are new to lipo batteries. I use 2 large cinder blocks and charge in the cavity like you showed. Love the idea of putting sand on top. Thanks for being awesome!

[@WVRick]

For years I've used a Treadplate Steel 20x10" toolbox on the floor with pavers brick between the box and floor. Away from anything flammable. Ammo cans for storage.. Great video!

[@StoneBlueAirlines]

Raise your hands up if your wife now hates your hobby even more because you want to build this. ;) Safety first. Thumbs up!

[@garthfpvtv]

***** Tell her that and you might get the ultimatum you don't want.

[@PHeMoX]

If you truly believe in Safety First, you really wouldn't ever need a lipo bunker.

[@garthfpvtv]

lol. watch the news and listen to politicians.

[@ColtonB]

***** My girlfriend heavily supports me! I'm sorry for all those who have un-supportive spouses! I know a guy who just drilled a hole in the top of a safe and drops the battery in while charging. He had extended cables of course. I really need a safe area to charge my batteries!

[@Electronzap]

Learned a lot! I thought up the bag of something above the battery to put out a fire, didn't think of it containing something as simple as sand. Looks really effective.

[@DargoDog]

One of the best videos I have seen on LiPo safety! Currently, I have mine charging on an all metal rack (baker's rack) and using old licence plates for the bottom. I do have several larger ammo cans that I have thought about using for charging and storage, but I did not know if it was safe or not. Looks like you guys just gave me my next project!

[@ManuelMcLure]

Please, please, PLEASE stop recommending salt water for discharging LiPos!!!! All that happens in salt water is that electrolysis corrodes the terminals of the battery before the battery gets anywhere near full discharge. The correct way to discharge a LiPo for disposal is to use a resistive load, such as one or two taillight batteries in series.

[@kirkglundal4289]

Yes, Salt water is NOT a solution for lipos. For a little more than the cost of a couple pounds of salt and takes up far less room than a pail of water you can use this: URUAV Lipo Killer. www.rcgroups.com/forums/showthread.php?3270863-The-Perfect-Lipo-discharge-tool-URUAV-Lipo-Discharger-how-to-Hack-DIY

[@Enzo-kl2vc]

Also, DON'T use an AMMO BOX if it is airtight. LiPos absolutely need holes for gas to vent out, otherwise the pressure will build up inside the ammo box, effectively turning it into a BOMB. Ammo boxes are great IF you drill holes in it for gas release.

[@antoncasciano8747]

@@Enzo-kl2vc just take rubber seal out

[@williamadventures]

This is my first FT Build! Went to home depot and the clerk mentioned the sales rep for the cement board brought a flame torch to show them how resistant it was to fire. I put mine together and happy to have it. One of our local guys just had his car catch on fire. Console, seats and interior. He was charging with an inverter. I do that all the time, too. I'm going to make a mini version to charge while at the field with spare pieces of cement board. Thanks for the great tip! Hope I never have to test the fire capabilities!

[@rolandgeorges960]

Better Safe than Sorry. Sometimes we get carried away by minor things and forget the foremost important things. Congratulations guys, very educational.

[@ausguitarist]

I only have 2, 4s 2600mh batteries and i bought some 2, $10 metal toolboxes and lined them, twice with scrap concrete sheeting, the 10mm type. store them seperately in the garage

[@CraZyCarl6212]

After seeing a lipo fire at my local track recently, I built my own lipo bunker. I used 2" tall 12"x12" patio blocks on the floor. Then put standard cinder blocks laid on their sides on top so the 2 hollowed out spaces of each block are faced up. That gave me 4 separate compartments total. 3 of them are used for battery storage, 1 is used only for charging. I also added an extended balance lead to my charger so the charger can be kept away from the charging battery. I like the idea of the granite board used in the video, Ill buy some of that to make a top. My favorite suggestion though is the bucket of sand, so inexpensive yet effective counter to a lipo fire. Also the smoke alarm, ill be adding that too. Thank you for the ideas.

[@Commandodesigns]

Well done. Yes, the big one is .50 cal and the little one is 7.62...

[@SuperJaveline]

...will it blend?.... ...ah....wrong KZbin channel ;) ...but, seriously, it's good to see a well known player in the rc scene promoting awareness and safety message. Well done guys, really glad I subbed to your channel.

[@jameslow5738]

The sandbag over the batteries to let the flame melt the bag and release the sand is an amazing idea

[@TheHouseBlog]

I'm really surprised that there are people who don't balance on every charge. Not saying if it's wrong or right, but rare. With the people and fields I fly at that is virtually unheard of aside from the occasionally new guy. We also deal with larger packs like 12s and such so maybe it's just more common with the higher cell count packs.

[@hakont.4960]

If the battery cells are resistance matched it's in most cases not necessary to balance the cells each time. I don't balance the cells each time, but I always connect the balancing plug and check the cell voltages. Usually the cells are balanced to within .01 volts, and stay balanced even if I don't balance them every time. I do balance them occasionally, just to be safe of course, and always store them with optimal cell storing voltage.

[@PHeMoX]

Yes, always do a balance charge. There's no point not to.

[@hakont.4960]

PHeMoX Unbalanced charging takes less time, and isn't a problem with high quality battery packs and if you know what you're doing. I occasionally check the individual cell voltages with a multimeter just to be safe.

[@tomsunax]

Thanks for those tips, probably good for many of us to be reminded to be careful with lipos Balance lead extension cables exist (think HK has them) in case you want to put the charger outside the bunker

[@mbainrot]

it's what i do so I can run balance leads into me fire bags

[@SeanDuffyProductions]

I've always charged my batteries using the balance lead, my charger doesn't have a connecter for the power lead and I wasn't even aware you could do it that way! Is it bad to always balance charge, or is it just slower?

[@DjRio0001]

Not bad at all... Just slower. You're actually likely to have better lifespan in your lipo because of the low C charging. My IMAX can actually do both, so they only discharge by the balance plug but do the bulk of the charging via the XT-60

[@RCBuyerreview]

nice bunker)

[@humusiclab8974]

May thanks! Would it work to fill small amp case with sand? Other than being heavy, you could put several batteries in there at once. One battery issue might not set off the others, at least that's the theory...

[@andy-the-gardener]

the sand is the best idea. as long as your in the room (and you should be), you can deal with the situation.

[@evhexrc1765]

Very helpful! I love the ideas! Keep it up! Would charging lipos in a glass mason jar with a metal lid that has a small hole cut in the top to run the leads to the charger?

[@mbainrot]

no not good idea as the heat will shatter the glass

[@Dreiviertel]

I got one of the ordinary plastic euroboxes, inside are freezer bags filled with extinguisher granule. Here in Europe the brand ist called "Extover" or "Fireballs". Basically "foam glass balls" that are melting at high temperatures, drawing energy from the fire and extinguishes it. Costs around 50€ and I got a storage with a passive fire extinguisher.

[@LIFEOFSTUFFEDANIMALS]

I have noticed with great interest that there is a Park Zone Sukhoi SU-29MM behind you. Will you guys do a video specifically on that RC aircraft soon? I have heard many great things about it, and since you guys are amazing at reviewing RC planes, I thought it would be likely.

[@TROYJDONAHUE]

I saw a test where with these ammo cans the fire did more damage with the seal in the lid, when the seal was removed not as much damage

[@matusknives]

Awesome video, thank you. I will definitely be building something along these line in the garage to minimize any potential damage.

[@keylitho]

I'm surprised you didn't mention thermal sensors.. I have a Triton 2 and it has a thermal sensor that you put on the battery and it shuts off the charger if the battery gets too hot.

[@jimfang2090]

your lipo bunk you tube segment rotated to the top of my you tube page. THANK YOU !!, great info

[@MrGantzFan]

How do you guys recommend safely storing batteries? I currently use lipo sacks, but admittedly overpack them. It gets to be expensive to use 1 lipo sack for 2 or 3 lipos. Is it safe enough to store 4 to 6 in a single ammo can?

[@302elite]

I have heard from a great community of people that say you can not leave your battery fully charged or that can puff it if I sit over time. When a battery puffs up it damages the cells in the battery. One thing to try. Try a puffed 3 cell pack and a regular 3 cell pack put together o the same plane. Well when you bring it back the puffed pack will have a lot less voltage left than the regular pack.

[@BeginnersTech314]

very important info. I just had a fire from a lipo and lost all my RC stuff and almost everything in the house. you can't put them out. great information.

[@whitehedr]

Great tips on SAFE battery charging techniques. I really like the one you payed forward from Utah Flyers. ROG

[@rufo]

Could one store and/or charge LiPo batteries in an old casserole with a lid on it to contain any flames or heat within it?

[@ChongMcBong]

Am i safe keeping 20 lipo batteries together in a sealed ammo case? They are all 1 cell, and are under 500mAh, and have individual slots in a lump of foam, so i assume they are reasonably safe, but does my ammo case need a vent to stop it blowing up? I like the cinder block charging bunker idea, that looks safe, I'm just worried about my ammo case going off like a grenade if something happens to one of my sleeping batteries, also thinking it will shoot flames out if i cut a vent in it, so need some advice...

[@geoffreygoerlich1499]

Is that the new Sukhoi SU-29MM BNF Basic by ParkZone in the background?

[@eddielane9569]

Make sure to remove the black rubber seal from the top of the ammo can so it won't catch fire and it could also build up pressure in the can and cause it to explode. If you use a ammo can or other metal container make sure to set it on something that won't catch fire like wood or plastic or line it with sheetrock or cement board.

[@jkspinalchoice]

wow!!! This show was probably one of the most important one I have ever watched. I knew these batteries had the possibility of catching fire, but NEVER did I know to that extent. I fly the Phantom 2+ Just went into my Gun Safe, and pulled out one of my ammo boxes, and am using setting up as you showed in show. To test the batteries that I have, is there a particular device to use, or the one you were using does all sizes? Guys, as usual Great job!!!! John Kaddouri

[@drkastenbrot]

A generic lipo checker will do that. The lcd ones.

[@mrlegodude96alt2]

+John Kaddouri Quick note if your using military grade ammo boxes they're air tight so if there is a fire the pressure will build up until it blows the top off, I have small holes to relieve the pressure.

[@optionalcoast7478]

+mrlegodude96alt2 well it would be the opposite since the fire would consume the air in their but still bad

[@mrlegodude96alt2]

Optionalcoast74 I've blown up multiple ammo boxes with old batteries to prove this point lol, either way it's still a fire in a pressurized container.

[@PaulKruskamp]

+mrlegodude96alt2 what could go wrong?

[@AlvinBustamante]

Is there a maximum length for balance wires? I want to charge my battery inside an ammo can lined Hardiebacker.

[@kokoslegend4850]

Why would a charger overcharge them with the balance plugs in?

[@RackwitzG]

I‘m starting to get back in the hobby again after a 25 year break and can‘t get around lipos if I want to fly. I’m freaked out by the thought of a fire. I live in an apartment and have no outside area to charge or store my batteries, nor a garage. My only hope is to not make mistakes and hope an ammocan holds up. I guess you have to be brave in this new world... :D This Vid was very helpful, thanks.

[@heatherryan9820]

I'm just curious, could you use baking soda to put it the fire instead of sand?

[@RCSurf]

I see that parkzone Sukhoi 29mm back there when is the review comming?

[@locouk]

Great tips guys, I didn't know about the sand for a lipo fire.

[@MountainSnowFlyer]

What is the best way to dispose of old lipos and partially burned ones?

[@soulis1000]

There is extension cord for the balance Cable too you know? Keep your charger outside and just the battery inside.

[@benjaminvanbrande38]

Well if you just want a tricopter and your dedicated to that I would go with the Bat Bone TRI shop.flitetest.com/multirotors/bat-bone-tri-370-kit/ But if you wanted somthing that later on you could change to a quad or what ever i would go with the anycoptoter becuase that gives you more diversity and its also a little bit cheaper. I hope this helps. :)

[@Ghostrider03Z]

Probably buying or cutting your own frame plates of davids tricopter and building from there would be the best. If you want to spend some more money on a frame, you could buy a turnigy talon frame or something similiar. Then 5.8 fpv would be the best to start. If you are curios as to what you need for a 5.8 system i have a video on my channel.

[@lennertbontinck]

thanks guys!! I I'm probably going to follow David's built and for fpv I might go for a cheap boscam fpv setup with my mobius connected :D anyone has experience with boscam? i might buy a set from banggood but I have no experience at all with fpv setups... Is this one good? I want at least 100 meters of range and i'm going to connect a mobius or a cheap board cam...www.banggood.com/Boscam-FPV-5_8G-400mW-AV-Receiver-RC805-With-Transmitter-TS353-p-918123.html thanks!

i loved the toolbox idea... muck easyer to store at home

[@garyhale5645]

Line the inside of your large ammo cans with another layer of protection. If kept inside weld a piece of muffler pipe to the can and cut out circle in the can. Drill a hole in the side of the building to the outside and run pipe thru it to the outside. Epoxy a piece of screen to the end of the pipe using rubber bands to old in place till epoxy drys. Keep seal on can if you vent outside so it doesn't leak smoke into the room

[@phcalama]

Where did you find the smoke detector you used?

[@mikeberg22se]

Good info. Why not put a block between the charger and battery as well. That way you save the charger if the battery fails.

[@JoniDLE]

Thanks for sharing the safety precaution.

[@davidgibson1524]

I have one battery that is out of balance by .1 volt, should this one be neutralized and discarded?

[@joblessalex]

So why haven't battery manufacturers just built circuits that let one cell charge 100% then flip over and charge the next? Or a board that charges all cells to a cutoff and then kills the current? Is there something I'm missing or are people just slow?

[@littlestworkshop]

Electronics to do that from the main battery connections would have to have mosfets as large as you find in a speed controller. The cost, size and extra weight make it impractical and would also add extra losses and an additional point of failure. Using the balancing connector is the way to go.

[@joblessalex]

***** Surface mount mosfets exist.... They could also be in the charger instead and just have two sets of cables.

[@littlestworkshop]

joblessalex That is what the balancing lead already does, if you connect with the balancing lead then each cell is charged individually (like discussed in the video) but what you suggest above is more or less building a charger into a battery. Of course SMT mosfets exist but it's still impractical and people would not pay for it.

[@joblessalex]

***** Tiny relays.

[@littlestworkshop]

joblessalex Given these will also have to pass motor currents they will not be very tiny.

[@KenAllison-AVH-Australia]

[@dave_s_vids]

So where are you all storing your batteries overnight? I only have 3x 1000mah 3S batteries currently so they sit overnight in a lipo bag on a tiled floor away from anything combustible. Is it worth getting a metal can to keep them outside in?

[@ToekneeToe]

Get long leads for your charger. That way you won't hurt your charger. Make sure you have proper gauge wires. You can also use pots and pan with heavy lids or put stuff on top of the lids. You can put a ceramic or corning glass plate/bowl inside too. Thanks for get Video!

[@johnrobinson1140]

I'm trusting that slow balance charging of good quality batteries with my EZ PRO DUO will help keep me safe. I never leave them alone while charging, I check the batteries to see if they're getting warm or hot, and today I will probably check them with my Klein multimeter when they get close to charged just to make sure there are no discrepancies. And even then I dont really feel safe. 🤔

[@DjRio0001]

Please correct me on this one: Aren't home smoke detectors really just light sensors detecting slight variations in light caused by smoke? If that's the case, would it work in a pitch black box?

[@traviswright2174]

There's actually a microgram amount of Americium inside of them, which is a radioactive element. It's so small the radiation is harmless. And a sensor which detects the small changes in the radiation due to smoke.

[@henningschaferhoff1533]

Travis Wright there are two versions commonly available the one with americum and others with a light and a light sensor which is reacting to the smoke

[@TheTechOnline]

Americium ionises the air in normal conditions which produces a small charge which the detector picks up. When smoke goes into the detector it cannot ionise as much air so the no charge is produced which sets of the alarm. British GCSE Physics knowledge for your there!

[@lukegibson2110]

is ti the silver guy on the flite test logo?

[@CKOD]

I use a ammo can personally. I lined it with 2 layers of 1/2" drywall, which is surprisingly flame resistant. (seriously, try it out, I took a propane torch to the drywall for 1 minute, the paper on the torch side charred, but it treated to not catch fire, and the other side didnt even discolor, despite the torch side being orange hot where the flame was hitting it when I pulled the torch away) Also, I emphasize the point of the fumes being quite nasty. If youre charging in a garage (or any other closed space)and the smoke detector goes off and the garage is full of smoke, the first thing you should do is ventilate. Dont worry about the charger, or anything else, get the fumes out first.

[@patb5266]

Some chargers won't work without balance cable attached. I balance every charge and always use a separate bag for each charge.

[@hairymanjack6767]

Not really the greatest thing to do because it where's the battery down alot and the liposuction won't have a long life but it is good to balance charge it just not all the time I only balance charge my lipo when it is out of ballance.

[@patb5266]

CircuitX I've had no issues charging this way at all. It's not required to balance overtime but as I said some chargers require it> I have one the won't charge without balance cable and bought a new one that will balance without as I need one to LiHV.

What about how toxic the smoke is? Or was it mentioned in the video and I missed it?

[@Nemesis-pe7mw]

Did you even test that setup?

[@agrsk8r]

My Turnigy Accucell 6 won't even charge without using the balance cable... unless I'm charging single cells, of course. If you care for your batteries and want them to last a long time, it just makes sense to keep them balanced anyway. I've also observed, since I picked up that HK-010 Power Analyzer, that if you drop below 7% or so, that's usually where the cells start to unbalance. So that's one reason it's important to try not to drop below 10%. I didn't know that it was the law to carry lipos in a fire proof bag on a plane. But when I moved from Germany back to the U.S. a couple of months ago, I threw all of my batteries in my charging bags anyway because it just made sense to play it safe. I've been curious as to why they never said anything to me. Now I know.

Better to be safe than sorry, i only use 2s 3s and 4s lipos atm and i always balance charge, i also keep my lipos at storage voltage so they are less likely to puff, i keep mine in a metal toolbox, i like the idea of those cinder blocks, especially for storing lipos and keeping them segregated so if one goes up, they all dont go up. Great vid guys :-)

Why is balance plugs so short? Can i make the longer

[@CDC444RC]

I am making a version of this but I am using all cement board (no bricks). I'm also planning on making some smaller sections inside to hold each battery and put sand bags on top on these sections to put out any fire asap. The whole thing will be in a larger bunker in case the first compartments or sand method fails. What glue could I use to stick the cement board together. Gorilla glue works well to stick but in tests it loses strength quickly when heated with a flame. What else could I try that is cheap and easy? Thanks for any help!

[@CDC444RC]

+CDC444RC Anyone?

[@BubbaCZekLP]

+CDC444RC in your local shop you should be able to find a heat resistant glue, Which is normally used on chimney.

[@CDC444RC]

+BestLeblancEUNE Thanks. I ended up using a fire sealant and so far its worked fine. Tested by burning some paper inside and it works good so far. If I put a blowtorch to the glue it quickly weakens so it is not 100% fireproof. I use the sand bag on top method so it should how up long enough to melt the bag.

[@BubbaCZekLP]

Great!

[@Prem_hall_713]

so, I have a few one cell lipos, I was wondering if I still need to store, and watch my batteries charging? they don't have balance plugs, so are they safer than other lipos?

[@OregonDARRYL]

The holes in the concrete blocks look perfect to slide a battery inside to charge... then block the ends. Done. Try it... it will work.

[@DAS-Videos]

I've found that the turnigy batteries tend to bulge after a flight. I do not use turnigy batteries any more. They are low quality batteries based on my experience.

What charger and power supply do you guys use?

[@richt2633]

Hey guys, what is the small fire detector brand shown in the video? Thnx!

[@rcolborne4123]

I simply use rock wool insulation, cut slits in the middle of block and insert battery. It is 100% fire proof and if you insert the battery deep enough it will have very limited access to air and no external fire and very little smoke. Cheap and effective.

[@philg6757]

I just use a $5 metal mail box,all the cables run through the mail hole. You can line the inside with cut down Lipo bags or a fire blanket if you want.

[@55Rumble]

Another thing you can get hold of will be a LiPo Gas detector.... These detect gas WAY before you get anywhere near a fire.... I think they are expensive but it might save a fire all together.... IF the "magic smoke" dose escape, it is EXTREMELY toxic and will damage you! I think we all know the ultimate price for not looking after a LiPo so I am building a bunker AND looking into a gas alarm....we have them at work so I'll get some info... and re-post...

[@sallerc]

+55Rumble Good idea, did you find that info about the gas detector?

[@55Rumble]

+salle rc No, I'll try to remember tomorrow... as an idea of how bad these things are, I had a batter go in a boat... the gasses stripped the coating of my motor and just about wrecked all my dc gear. I put what was left of the pack into a Lipo bag and put that into me tool kit to go home.... after a short 7 mile drive all of my tools had started to rust....

[@sallerc]
