[@BamisayeBabafemi]

Will, I have an interesting theory that you might have to cross-check. I am of the view that it was the drilling movement that initiated the fire and not the mere exposure of the lithium-ion. What was done in the video sent to you is different from your experience.

[@bernardthedisappointedowl6938]

Great to see your primal joy in setting something on fire, ^oo^

[@KarlKarsnark]

their screwdriver also made it so very little oxygen was reaching the interior of the cell. the heat/chips from the drill may not have helped, but you should be able to drill through it many times with no issue. SS still has a long way to go. Toyota supposedly has something "amazing" in the works, supposedly. Thanks for a great vid!

[@EnFuego79]

3:05 "If I get cancer, it's because of this" LMAO!

[@teslapilotcheapreviews8490]

Hi Will, What happened at 2:54 ? Is it the essentially the same solid state model ?

[@davebagley6499]

And this is why I appreciate your tear-downs. Thanks for your professional attitude Will.

[@cdoublejj]

i'm with max headroom on this, any "review" that doesn't have a tear down isn't a review.

[@kele1264]

I agree. I feel a little guilty that this one was fun!

[@jamesscott1932]

Initially I thought the thumbnail was Clickbait. Then, having watched the video Will has proven out that claims by manufacturers must be tested. They are just puffing until they are tested and proven right or wrong.

[@someOneYouKnow6506]

[@TeamBehrens]

Love the genuine laughs. I would be doing the same!!

[@MJ-ge6jz]

This by far was the most exciting Will Prowse video I have seen! This is why I only use Lithium Phosphate You just don't run into those kinds of explosive issues!

[@leonordin3052]

Though then you get low amp draw, low power.

[@jetfu400]

@@leonordin3052 low amp power draw? that' not accurate. c rating is lower compared to li-ion. but that doesn't mean it's low. its just lower in conparison.

[@veganpotterthevegan]

​@@tokoloshimampara9932 for sure, you could also drop a LiFePO4 battery on your foot too. Definitely risky.

[@roberthernandez7564]

Glad you posted this. Can't say your test was the same as the Chins test since the drill created far more friction than a sharp object being shoved directly through a cel with no rotational force. But your point is still very valid. Battery chemistries of any kind are flammable.

[@WillProwse]

Yes very true, but if this was LiFePO4 and the drill's friction caused combustion of the electrolyte, it would be a nice slow burn. Going by this reaction, we can see it has cobalt, oxygen was released and reacted rapidly.

[@WillProwse]

Really wild to see it have a self-propagating runaway like lithium polymer. I was not expecting that. I do not think this is a true solid state cell. Even though the data sheet claims that it is.

[@georgemead6608]

This presents a very serious issue when used inside any structure. What happens when the device is exposed to an external fire. Perhaps one that would be manageable without the batteries.

[@notreal5311]

Great video. I'd like to see another cell tested with puncture only like the Chin engineer video. Also similar tests with a LiFePO4. Sure it'll get a bunch of views also! Thanks again!

[@RobertLowery]

Will, As a Fire Marshal we are seeing more and more training videos for all the various rechargeable batteries and charging systems. It is only a matter of time before there is a huge, HUGE fire in a storage or charging facility of battery systems. With electric vehicles and more and more solar systems in use than ever before, Fire Departments will be having their hands full!!!

[@FirstLastOne]

It's already happening with people stealing parts here and there and trying to cobble together an e-bike or scooter in their home only to have it set fire to the whole place and leave many people homeless in the process if they are lucky enough to get out alive.

[@jamesray9009]

I have a great Idea to isolate and possible prevent house battery fires.. Hempcrete small room for them.. I'm positive that it would keep a battery fire from spreading.. electrical outside of that couldn't really change more than regular. But hempcrete at 1' think has r30 ish insulation factor so keeping them at a optimal temp would also be easier..

[@exotichandyman]

The Felicity Ace caught fire and sank because of the batteries in the cars.

[@acmebrainsurgery]

@@jamesray9009 I was thinking a small concrete room w/ whatever fire extinguisher works best. Would water exacerbate a battery fire, or not?

This was the most entertaining video you've produced. Really appreciate the time you take to tear down these units to show us what's really going on inside.

When you were running away laughing, it brought me instantly way back to my childhood and my brothers and I running and laughing uncontrollably. Thanks for that.. R.I.P. Billy and Johnny

[@livergen]

Bless your heart Will, Good Lord brother, that was exciting to say the least. I'm so glad you took it outside for the final puncturing, that would have been a real bummer for it to catch on fire on your workbench and inside your home. Been watching you for a few years now, and because you're so down to earth and have such a straightforward way of explaining things (( you make it fun just listening to you )) I actually built my own solar generator and achieved complete success in doing so. So glad to see you doing well and enjoying life, I'm sure everyone on your channel (( like myself )) thoroughly enjoy all that you do for us. You have provided so much valuable information Will , and your time and effort is priceless to all of us out here just trying to achieve some level of independence and backup power systems. No one wants to be caught in the dark that's for sure, and you have definitely provided so much light to our lives. Stay blessed and keep yourself safe, the world is going sideways it seems at times, so please take nothing for granted as you're out and about. Danny in Texas

[@azclaimjumper]

I'm still chuckling several hours after watching this video Warm Regards from Reno, Nevada

[@qapla]

If you noticed, on their puncture test, they left the puncture probe in the battery - when you drilled, you pulled the bit out and allowed oxygen in - it would have been interesting to see what result they would have gotten if they had pulled their probe out

[@donaldreynolds4003]

Hearing you laugh and run away from that fire had me laughing out loud. That was crazy to see the volatility of that pouch.

[@PH_INFO_101]

Hey Will, As a retired Haz-Mat safety specialist, I will let you slide on the on the rubber "Crocs", but may I suggest adding some Fire Resistant Nomex Socks to your clothing attire. I am not saying as an everyday thing but for situations like this, Safety is #1. Actually, on second thought, It would be hilarious to see you in full bunker gear while performing tests like this. You can purchase some nice used lightweight bunker gear on eBay that would go great with your Crocs & Nomex socks

Thankfully, you didn't get burned. I think the cells were quite what the manufacturer stated. Good review. Thanks!

[@ES-1984]

If you're going to test to failure (which was awesome by the way) you might want to make a little firepit outside with some cheap blocks from Home Depot or Lowe's so you don't end up staining your sidewalk or driveway.

Glad you finally put safety glasses on!

[@mrsjohnson1743]

In the demo that the manufacturer sent you, they did not remove the item that punctured it. It was a plug then. your puncture caused the gas to emit after the drill bit heated up with speed, that’s when the real fire started. That was fun! Thanks for showing us the crap we need to stay away from.

[@lcinflorida8728]

That was freaking nuts! TY for the educational and entertaining content!

Good video Will. Chinn's was right it's a semi-solid state till it gets damaged then its semi-volatile. Looked like microwave popcorn pouch I would not what to have those in an unsecured-protected location let alone the hazards to off gassing. Thanks for the video looks like fun Stay Safe & Good Luck

[@Capt-John-T-Moore]

I actually commented on another KZbin channel about someone touting solid state batteries, but they didn’t mention it was lithium ion batteries with a solid state system. I didn’t understand what they meant by solid state batteries. So I looked up the brand they were saying as the next best thing and found out it is just another lithium ion batteries type. When I called them out on it. They either don’t read all their comments or they just ignored my comment. I specifically mentioned they could be a more fire hazard. Thanks for exposing the risk. I watch a lot of your videos. To help me with my solar designs for my new house and our off grid Rv

[@ReflectedMiles]

Very funny! 🤣 As soon as you took a drill bit to it, I thought , "So much for a puncture test! Now we're going to do a can-I-get-it-to-blow-up-for-KZbin friction test!" Nice to see a preliminary look at solid state. It will be interesting to see the refinements to follow.

[@douglaslin5469]

If this battery was mounted in for instance my boat's lazarette (which is the storage space under the main cabin's coach seats) and someone put a fitting into that space with a drill ... such an adventure could very well happen. Not sure though about what would happen with Lithium Iron Phosphate Prismatic cells. Such batteries are installed in plastic boxes though, which adds some distance ...

[@MattLesak]

The smile on your face when you said let's take it outside cracked me up. Crazy to see the reaction. WTH!

[@JeffSkymaster]

Thanks Will for 2 Videos today, was wondering what you have been up to.

[@revtoyota]

Great video Will.. I asked in one of the last videos about UPS (Cyber Power and APC) battery swaps from lead acid to Lifepo4. The reason I asked is Chins and Ampere Time had it in the listings title in Amazon but now looks like they removed UPS from the titles. Still might be worth the video just to inform people.

[@FirstLastOne]

It would be interesting to see the actual cells of a Chins and Ampere Time LiFePO4 battery because CanBat has a direct 12V 9AH LiFePO4 replacement for the standard sized 12V 7-9AH SLA batteries. They stand behind them with a 10 year warranty. I am using them in a lot of UPS units having replaced the 12V 9AH SLA with CanBat 12V 9AH LiFePO4 batteries. With that change, I now get just over twice the run time on any UPS I have installed them in.

[@sonictech1000]

@@FirstLastOne How long have you been using these and I what UPS's? Good replacement batteries have gotten hard to find.

[@gravelydon7072]

@@sonictech1000 Not First Last but I also have switched to LiFePO4 batteries in the UPS Both ACC and Cyber power units. They cost more than the SLAs but seem to run longer and are the same size outside. Open one up for the surprise though. More dead space than you would think. Mine have been in for over a year now and no problems. One of the old SLAs was hard to get out as it had ruptured the case.

[@cowboymcq6711]

SWEET BUT SCARY ❕👍🏼 I love the looks of your back yard solar panels everywhere Keep the fantastic videos coming Will

[@joshsk8erx1]

In their example the puncturing device was left in place not allowing the electrolyte to be exposed to air. In your example, you created a hole with the drill and the hole was open to air. So it's only kind of safe... only if you use a screwdriver or something like that to puncture it and then leave it in place. ..

[@l.bustamante1442]

plus, heat was generated by the drill

[@robertfreeman2322]

These are the same type of batteries that were in my sons electric skateboard that caught on fire just sitting on the back deck. My marine electrician saw my son riding it down near the marina and he told me to make sure he doesn't bring it in the house or charge it in the house because they have cheap ass pouch batteries that are notorious for catching on fire and no BMS as they just use a real small charger at like 2 amps or something. I owe him one because that's exactly what happened. It got some moisture in it I think and something shorted, but that thing was spewing some big flames. The guy from the company said he'd send us a new one if we gave him a good review. Told Amazon about it and they refunded us our money. 2 weeks later a new board showed up and I brought it to the recycling center.

[@E.X.P.E.R.I.M.E.N.T.A.L]

The drill bit temp ignite it from inside at very high temp. In normal condition will not ignite nor smell as you just demonstrated with the punch hole in the first place. I remember the drill bit rotation will even burn the metal that can get red hot.

[@newscoulomb3705]

When you hit it with the drill, I immediately started smelling ozone. 🤣

[@siraff4461]

Also remember this is relatively early days for SS. Early li-ion weren't all that great either. I remember my first Leaf which could allegedly charge at 50kW but only ever got to 36kW and then only for a very short time in the middle of the battery. Contrast that to my model S and that thing could eat 100kW easily anywhere between around 10% and around 80%. That was in 2017 and plenty of improvements have been made since. If SS can improve at that rate its going to be brilliant in about 5 years time.

[@audigex]

Yeah on your car analogy, my Model 3 can charge at over 200kW, and there are some EVs pushing above 300 kW now even!

[@fulldnbboy]

And yet it doesnt matter if its 100kW, 200kW, 300kW or even 1MW. All it matters is that in the batterypack each cell should get below 1C of charge. For an example, if your model S eats during charging 300kW but you have enough battery cells in the batterypack, just divide those 300kW with cell amount and you will find out how many watts each cell is getting during charging. Now, you each of your cells is getting 4W, then your amperage to each cell will be 1A. 1A is well below hazard limit. With largest batterypacks in cars, there are even 0.5A of current on each cell during charging, that is already well below even normal charge, its safe, its even benefitial for the cell to be charged at lower currents. In short, it does not matter how many watts your car is taking from the grid during charging. What matters is that each cell during charging gets below 1C of charging current at any time for safety and longetivity of the battery during its lifespan. Its not those 300kW that kills your battery and creates fire, its the one cell that overheats and starts burning, igniting all other cells within its reach creating runaway cycle. At that point your charger is already disconnected from the car and not supplying all those 300kW because all the safety and sensing circuits in the chargers and in the car itself.

[@siraff4461]

@@audigex My big take away from this is that even at this early stage its holding close on twice the capacity by volume. The 1/3c rate for what appears to be non cooled cells in an enclosed box suggests they could go quite a bit higher in a liquid cooled application such as a car already and if its twice the size it only needs to charge at half the c rate. Lets say a 100kWh li-ion takes 2c reliably - then the equivalent in this would be a 200kWh taking 1c. Charge per minute would stay the same so 10-80% would look poor but it would only need to go from 20-55% to hold the same amount anyway. Depending on how they behave at the top and bottom of their charging I could see these even being quicker to take on the equivalent amount of energy as a 5%-100% li-ion through sheer capacity.

[@alibro7512]

Love the safety Crocs. 😋
