FILM RIOT "Cinema Pack" "Horror Pack" "Block Buster Pack" / @filmriot - Zábava
Says he’s studies batteries for years...
**immediately cuts and shorts all the balance leads at once**
YUP!!! That was my mistake. But it was also kind of the joke of the video. We met a few years ago, Peter. I'm a huge fan! I even said while filming this it'd be great to work with Peter on this since he'd do a much better job, but that didn't make the cut.
Peter Sripol!
lol, all my favorite creators are in the make videos for the same demographic of people same demographic.
exactly. Awesome to see you here Peter!
I remember you guys meeting up at flight fest or something right? Its also weird seeing peter here. I am also one of the lucky people with my username burned into his table ;-)
Thanks for all of your concern everyone! You're all correct, I absolutely should have been wearing eye protection. Secondly, yeah cutting up the batteries the way I did was dumb. But were you not entertained at least?
How do I charge the battery? Through the micro-USB port, just like a normal powerbank! It's capacity is 80,000 mAh so it's pretty big!
How long you need to charge the battery from nearly empty to full? And is there some source of battery charge amount indicator?
What's the charge time from near flat? 1 week?
Wren, i really love these little videos where you just create everyday things on a bigger scale. I do also make little things myseld and you have my unsafe support from the Netherlands hahaha. Because who needs ''safety'' glasses :P
next step is to make a wireless charging bank for 8 phones haha...do it you won't
i would really get like an XT60 connector for "fast charging" the battery using a buck converter you can set it to 4.1V, look for the charging rate on the original battery, for the C rating, or charging it at ~8 amps, will take you 10 ish hours (usb will take you ~60 hours (80ah*3.7v/5w))
I have made a festival battery (it's at a festival at the moment) it's a 3S 90Ah battery, so still some way to go for biggest powerbank!, i charge this with a balance lead and hobby charger. (balance charging for those who wonders)
Is it wrong that I found this episode to be the most entertaining of all episodes and films?
Agreed
Agreed
All episodes, yes
All films, no
Agreed
That is incorrect. You did not find this the most entertaining.
It never fails - when I'm using super glue and 3d printed parts, I always end up gluing myself to myself.
Haha!!! EVERY TIME!!!
"Why are you always leaving!?" LOL I love you guys
a little too soon; maybe?
@@oscarrebaza3389 nah
hahah I lost it
@@oscarrebaza3389 the faster we get over it the faster the recovery for us and the guys... and make it so that they dont worry about any of that and move on with there life
Looking at this now, he left...
Using tin snips to cut wires. Wren I'm starting to worry about your safety.
It was the only thing we had that could cut the thick metal tabs connecting each of the battery cells.
@@SirWrender buy some proper tools then ;). Peugot PC and cheap scissors can't go together
@@SirWrender Actually, the Fiskars scissors you had on the table prolly would've also done that. ;) Not that I'd recommend using them for this either, but they _could_ be used. Also, as a Finn, I kinda love the fact you've got so many Fiskars tools around. Here everyone's got Fiskars scissors and axes, but you still kinda think of them as this little metal working company from a fishing village on the southern coast of Finland.
I know this is late but most wire strippers have cutting tiers and a universal cutter (it helps to crimp the wire)
This felt like an ElectroBOOM video. 😂
Just without special effects and real danger
og memories
omfg i was just about to comment that
except he is actually incompetent, not just acting that way
Are you Justin Y.?
10:21 "Why are you always leaving?"
*that suddenly got way too real*
Bro, don’t remind us!
Welp, surprise surprise, he's back
surprise surprise the king is back
i dont think wren did study batteries ... maybe he looked at a couple pictures
Come on!!! I viewed at LEAST three pictures!!
@@SirWrender you have to be one of my favorites here idk who's my top but you're in top 2
Nah look back a coule years ago he was tinkering with Lipos even then!
I know that many of the guys in Corridor have grads in different areas. But I think that the electric engineer of the team is Niko, even though he doesn't do stuff himself. Jake is allegedly a lawyer.
@@NothingXemnas "Allegedly" Love it.
why is wren using gardening tools to cut up a battery
Have you been using tin snips are missed used for gardening like for pruning?
Don't question the guy with 3 years of practice. He has his reasons (I hope) xD
Because he has "studied them for years."
Just cause tin snips aren’t gardening implements (unlike his two shears and axe, and I’m only halfway through the video) doesn’t mean they’re the right tool for the job
IDK
“i studied batteries[...] i fell comfortable doing that“
*Battery nearly explodes*
Suprised pikachu face
😂😂
Wren: “i gotta wash my hands after this, its toxic”
Also Wren: *puts his hands in his face on **3:48** and **3:52*
One day Wren is gonna walk in with an Iron Man suit with the idea to upgrade its power cells & add a fast charging solar mesh & nobody is gonna question it.The FBI might but nobody in the office will
Until he short circuits the arc reactor by trying to add usb port.
now THIS is a great idea!!! My next project :)
@@SirWrender DO IT!, Make an Iron Man suit with servos and a HUD with a cheap HMD and a raspberry pi
@@patrickjenner3211 hacksmith industries already did that
Talk to Adam Savage, he already knows someone building one haha
Thanks for the bomb making tutorial.
if you do it right and balance charge the batteries nothing will happen but if you act like a dumbass and dont know how to do it then. you're fucked.
Yep 100% rigth
The title should be: "How To Disarm a Bomb"
This video pretty much showed how to make a bomb xD
you probably meant "how NOT to disarm a bomb" lol
"I gotta be really careful to not do that again"
**does it again**
Wreeeeeen! Missed opportunity there... You should've put some yellow translucent material behind the logo, so you could've put a light behind it, that would turn on when charging phones.
and a wireless pad under that. so that you have a wireless charger WHEREVER you want it to be...
I've rebuilt around 10 lipos and i still am not comfortable doing so. I have some suggestions though, firstly for safety, wear safety glasses. I never used to while soldering but if you short the contracts the solder can be launched and I burnt my eyelid that way. Second, always tape over all metal if it's not completely protected. Third, if it's a battery with regular wires, create strain relief. Lastly, if using cells from different batteries, discharge them to all the same voltage before joining them.
You did well protecting it at the end however cells in parallel can't be balanced so you might run into trouble. To finish my batteries i use liquid tape, packing tape with nylon fibers, and foam or cardboard or 3d printed spacers.
Btw my experience comes from drone racing and airsoft.
Cool video, keep building neat stuff Wren!
Actually, batteries in parallel self-balance! So there's nothing to worry there. In hindsight, yes I absolutely should have been wearing safety glasses though.
cells in parallel literally balance themselves. If when you connect two cells together they are at different voltages then the lower of the two will draw current from the higher cell. If the voltages are too different (like 0.5volts or more) then the higher voltage cell will overamp the lower cell and can cause it to puff or worse.
8:10 during the intro of this scene I was so confused on why he was choking him and couldn't stop laughing
I hate watching you guys do these projects with soldering and batteries. I build defibrillator batteries and seeing the way you handle it gives me so much anxiety lol. But it is entertaining...
I use a solar charger. I think the sun is bigger.
Soooooo.....
A sunbrero
Like if you get the referrance
@@basarthewarrior I got that reference!
Even the most expensive and state of the art solar panels of the same size as this brick wont be able to charge most phones to 100% in a day. In the end, most of them use a battery anyway, and take multiple full days before they are fully charged
@Crazycatsbackboi , true, but the joke is that the sun is really big.
I just use my semi truck. Ain't no sun but it works.
Discharging them first may have been a good idea, but it provided quality content nonetheless
I was about to say, did the power cells have to be charged for the surgery? Was that a step Wren insured was done before he took metal the terminals of multiple cells? What about a very wet work space? Did Wren make sure that he was sitting in gasoline? :P
Honestly though, I would have thought that and getting to an area with great ventilation, since the fumes of a ruptured power cell is toxic, would have been high on his priority list rather that just tools and fire extinguisher.
Well, he did mention that the battery as a whole was not functional, so perhaps it wasn't possible to discharge?
@@JIYkp you can discharge any battery by putting a load across it for it to discharge into. He could have put maybe a motor or a very large power resistor across the terminals until the voltage dropped to the discharge potentials
It's not really good to discharge a lipo to 0v - it can actually damage the cell
Lipo cells will always have voltage in them. He could have discharged to 3.2 volts but if he went any lower then the cells would not be able to recover and thus would "go bad" as you saw the 1 cell do at the start of the video which Wren removed.
Sam: "Hey can you use safety equipment or whatever?"
Wren: *squints as he solders batteries together*
Safety squints! :D
That last part tho :(
"Cmike! Why u always leaving"
Watches ElectroBoom once:
"I studied batteries for years"
Exactly 😂👌
No eye protection or gloves...? C'mon, Wren, you know better.
also gasmask
Nick shouting ‘WHY ARE YOU ALWAYS LEAVING?!’ to Cmike
1:05
Battery Cell* if I go down..YOUR COMING WITH ME *kills all battery cells*
Suddenly everyone in the comment section became electrical engineers
This. It's annoying.
There’s more energy in a phone battery than in a 45acp, and this is much bigger than a phone battery (source: licensed electrician with an Australian gun license)
But yeah so far seem like 4 useful comments and a lot of people repeating stuff
How is he going to charge the battery itself? Does the ports work the other way aswell?
Morten Larsen he did said theres one micro usb slot to charge the battery
@@skykingsman6634 Yh okay didn't hear that
I wonder what would happen if you charged the battery with all 4 micro USB ports at the same time.
KaadmY it'd charge a bit faster. Charging with all 4 ports is like charging with 1 port at a higher current. The battery is big enough that a higher current is fine
1:51 When your a kid at the grocery store and riding the cart with your mom
Wren: *making the largest possible powerbank.*
Me: you're a game changer!
"Fire extinguisher is right there" Yea well it won't do anything to help with a lipo fire.... I'm sure you know that though.......
Yeah but it will stop the things on fire staying on fire once the lipo runs out
on the plus side it will let you put out things that the lipo fire sets on fire
I'm not really qualified to object to your statement but fire extinguishers smother the fire, and fire needs oxygen to burn, so wouldn't it still go out. I could be totally wrong.
@@zacharydavis9526 depends on the type. I know in Australia we have many types, some that are not suited for electrical fires and some that are. (they have non conductive ingredients) However any fire extinguisher should handle a lipo fire because it's chemical
@@zacharydavis9526 Lipo's can burn without access to oxygen once they've started burning as the metal oxides in them will fuel the reaction. To contain a reaction sand and a chemical fire extinguisher goes a long way. Along with having it on something that's fire resistant.
"who's truck is this?"
*walks inside regardless*
"I'm using the wrong wire cutters for this" *drops tin snips *picks up pruning sheers lol
(just teasing Wren)
I have never seen anyone so excited and so surprised with aluminum than wren does🤣
*Wren:* HAAAA IT'S ALUUUMAANUM 2:09
Wren: The scissors shorted it out. I need to be really careful next time.
*Shorts it our 6 more times before getting up*
Wren needs ElectroBOOM's help.
I met him a couple weeks ago! Cool dude!
This was a fantastic video! I love seeing this wren shorts and I want them to keep coming!
I love Wrens little electronic projects it is part of the reason why im studying electrical engineering.
“Whose truck is this?”
*Next clip jumps in*
When I saw that intro I knew what was coming based on experience and working at a battery store for 4 years. Come on Wren your are literally shorting every cell at once when you cut it like that plus leaving all the leads that long can cause them to short to one another. Cut them individually are different lengths and much shorter. Also I wouldn't use those cells after that. They are damaged now but still its awesome. Also I have shorted multiple SLA batteries with my work soldering iron. I am always worried I will somehow fry the iron. I might be critical here but I *LOVE* these videos where you build stuff. Also I don't think I have said this before but Wren is my favorite on the channel which is weird since this was the Sam and Niko channel. but screw them.
Also is there a PO box or something I can send some soldering supplies in to? You guys could use one of those carbon filters (even though I never use one and holder lead solder with my mouth for a third hand) but for video safety it could be nice to have.
Nah they're not damaged now. It was through the balance leads, and only for a moment. The wires themselves would have burned up and melted far before damage to the battery would have occurred, and they only got hot to the touch.
I was taught with lithium batteries if they are shorted at all even for a split second is causes internal damage. I could have been told wrong of course and that may only apply to manufacturing.
@@x9x9x9x9x9 LiPo cells that big can handle a lot of current and the balance leads themselves act as resistors that limit the current so no real harm done.
It's a different story when you're dealing with manufacturing and actually selling "unused" batteries. There's a higher threshold for quality even if it's not that big of a deal.
The rainy corridor studio transitions were on point. Some juicy aesthetics.
“I’ve got to wash my hands after”
About 30 seconds later: wipes his face
7:47 You can see Wren die a little inside when he sees Sam's point.
When a new Corridor video drops 8:15
Man, rewatching this video was a blast. Also subtle little "Carmichaels leaving" at the end there
The friendship of clint and wren in this one is so amazing :))
You guys should definitely get an exhaust for the solder considering you use it quite often.
Lol Clint, "WHO DARES!!!"
I cant finish watching this - WREN! Something something right tool for the job. jfc you're making me anxious!
1:44 you know when I’m something of a scientist myself
Wren throw that out. Sorry buddy but they need to be charged at a specific rate. There are special circuits designed to regulate the voltage properly.
This may work for a while, but it has a good chance of blowing up randomly.
You may not be around to deap with iy when it happens, and it could burn down the building.
I build circuits on the daily, and I dont work with batteries very often, but I do know that it is extremely dangerous to diy this sort of thing, without understanding the math behind it all.
Also, depending on the quality of those chargers, they could damage your phones battery.
Can you be more specific? You used too many pronouns so I'm not sure what you mean.
So no response? I thought you said you "knew I wasn't experienced enough for this"
SirWrender Seems like he has a gaming channel, not a channel for circuits and things like that.
Well to help out, I have done a few circuits and it's amazing that with some time anyone can get out their doing it. Knowing what I've learned, throwing them in parallel like that won't help when it comes to long term use because they aren't being balanced. The best thing you could do for this project wren is to get a balance charger, but that steps up the voltage. To bring it back down step the voltage down with enough current to run all your units is probably best. A switching regulator is best for efficiency but an ldo or something else works. That being said you could also just hook each lipo to each board you bought there. Those are like $2 a piece or something and come with a charge controller ic on each. That way you don't have another cell dying from over discharge, overcharge, etc. If you're really interested in this stuff wren you should check out easyeda.com. You can design and order your own pcbs. I've done a few including an amp circuit. I'm working on one now for a bluetooth speaker and it uses a lipo cell. There shouldn't be discouragement and always some sort of positive alternative at the least in my eyes 😊
I swear, one of these days Wren is gonna kill himself doing something stupid like this. Love ya Wren!
At least he'll die doing something he loves!
C-mike I openly laughed at that last part in the video. Y'all are great!
Hey Wren, FYI, those cells need to have space to expand, they seemed a little tight in that box, make sure they're not too tight, else when you charge them or if you charge stuff for extended periods or if exposed to high temperatures, the probability of those cells failing/ blowing up is significantly higher! Hope you see this and adjust accordingly for safety!
I studied batteries
*Shorts everything*
Wren the bomb diffuser
just get a car battery and use that. it even has a handle to cary it
This has so much more capacity than a car battery. Literally 100 times... Seriously, look it up
Hey Corridor Crew! For quite a while I’ve wanted to learn how to solder, and I thought it would be a great idea for one of you to make a beginners how-to! I was thinking it should be one of you with less experience learning from someone in or out of corridor who has a lot of soldering experience! Thanks for this great vid can’t wait for the next one!
That "Why are you always leaving!?" comment from Nick in the end is so gold hahah!
They did surgery on a battery
Your wires will be doing voltage drop
When I first started these videos, I thought Wren was really weird...but after watching Corridor Crew for the past few days I legitimately love Wren, hes so funny and excitable and 100% a cat. Wren, keep being you and being amazing.
Wren: says literally anything
Life: CONTRADICTION!
Palms are sweaty
Knees weak
Arms are heavy
Wren's Battery
has blown up already
mum where's the spaghetti?
lol video upload 36 seconds ago... yep i got this
as soon as you held up the balance leads and said "cut" my entire body tensed up and I puckered a bit xD
Bringing that on film shoots to charge everything sounds super useful!
Watched it twice, but umm how will you charge the battery 😅
I'm pretty sure one of the circuit boards soldered together with it was a charge controller.
The USB ports have a little micro-usb port to charge the whole battery like you would a regular powerbank. It'll just take a while haha
@@SirWrender Ok nice :D upgrading to usb-c isn't an option anymore? :P
It's gonna take a week to fully charge em haha. Maybe a few charger to charge since he has a few charger boards
Its so big itll last forever
@wrenthereaper The whole battery pack, new, can hold 16000 mAh. Remove one sixth of the cells, that should leave you with 13.3k mAh tops. A regular phone nowadays has a 3000 mAh battery. I say nowadays, but that's been around since 2014. That's *maybe* 4 and some full charges. With aging batteries and an inevitably lossy voltage conversion and charging I'd expect even less capacity and charges. Where did you get that 28 full charges from? How does that math work?
U R 2 dam smart
The original pack looked like it was 6 cells in series, which means each cell has a capacity of 16000 mAh. wren soldered them in parallel which means his pack now has a capacity of 80000 mAh. This can charge a phone of 3000 mAh 26 and bit times
Because reasons god damit! Lol
It was a 6s 16aH (355Wh) pack so it's 6 cells (16Ah each) wired in series. He wired it parallel so that's 80Ah (16*5) at 1S. Another way to look at it is the pack is now 296Wh and a phone is around 10Wh so that's about 28 full charges with charge losses.
You didn't account for the capacity going up when the cells are in parallel. It's a 16000 mAh battery, but with 6 cells meaning it's about 23 volts. When wired all up in parallel, that brings the voltage back down to 3.6V, but the capacity (minus the dead cell) goes up to 80,000 mAh. That's 5 times 16,000
So this is not 16Ah, it's 80Ah. That's a big battery!
You guys are my favorite channel. 8:08 had me surprised and rofl. Amazing.
I love when wren does stuff
8:17.. how to basic, is that you? :))
Lol wren invention
inwrention
Hahahaha you guys are the best. Science time with Wren! New series!!!
Glad to see the Deskercise bike from the job application footage getting used!
5:24 that is where you are wrong my friend. The do not get the same current the current is split evenly between the components!
But the current is maxed out by the "load", aka the USB ports attached to them. Since each USB circuit board is attached separately to the battery, they're only limited by how much current the battery can provide, which is FAR more than 4 USB boards can draw. So I'm not wrong.
Well done wren. You obviously know more than me as I just had a science test on the subject but you are right about it as your making more than one circuit!
Dear Americans,
It's pronounced "SOL - DER", not "SAW - DER"
Love,
Britain
'MURICA! screwin' up your language since 1776.
Inquisitor Shu then you should have spelled it with an L!
_oh wait, you did_
I noticed that Wren does that chuckle when he is either excited or scared; pretty much when he has adrenaline rush.
I love it when *Wren* put the tape to the *Clint’s* back and when camera panned at *Wren* , suddenly *Clint* just noticed and choked *Wren* with the tape to death while *Sam* goofy around. It’s so funny
Wren, we love ya bud, but hot damn do you make us nervous often with your dive right in choices sometimes!!! And watching you continue to sort out the battery hahaha
This is now my favorite crew video just because of the ending
Wren: Who's truck is this?
*immediately walks in to the truck*
8:15 The best out-of-context moment i've ever seen
Wren is a mad scientist. If you need any henchmen when the time comes -- hit me up.
It's always so pleasing to watch theses videos
Wren at 0:40 "I spend a couple of year studying batteries and know what I am doing", lets see shall we... no, you don't ;-))
Nick as carmicheal is being dragged to the anti energy void. "Why are you always leaving" 😂😂😂
That was super entertaining and interesting, loved the video.
love me some good ol wren diy/tutorial video
THIS CHANNEL IS DAMN GOOD, SO MUCH TO OFFER!!!!!
Damn, the rainy exterior shots might be the best B-Roll in Corridor history!!!
Honestly when wasn't Wren this crazy
Love that guy dissapearing in the end xD
Sam's input in this video was both very relevant and very *very* nice. I more used to an acidic aggressive Sam and it's always pleasing to see I'm totally wrong about that sometimes.
just love this, wren you're awesome
Great Job Wren! I only foresee ONE PROBLEM!
(I don't think you added a way to charge the Battery...)
Can we please get someone with IPC training or something to do wren's dirty work. It kills me every time
I honestly love the videos and you guys really do deserve more subs
A Corridor phone case would be cool. Thought of it when Wren made the box lid
