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!
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
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)

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.
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
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.
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.
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
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.
@@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
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.
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
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 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
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
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.
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!
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.
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.
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.
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 😊
@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?
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
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!
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!
i wonder what someone would think just seeing Wren walking down the street pulling along eight people on charger cables. like an overburdened dog walker
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

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
Hahahaha you guys are the best. Science time with Wren! New series!!!
They did surgery on a battery
‘I’ve spent a couple of years on batteries’
Literally not even two minutes later and Wren has almost blown up and fried his entire body😂
Your wires will be doing voltage drop
I love the lack of personal protection. 😂
Lol wren invention

2:22 “I don’t need this balance cable!”
*top ten famous last words*
@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!
This was a fantastic video! I love seeing this wren shorts and I want them to keep coming!
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!
Hahaha,,, He's sitting on the exercise bike desk from the footage they give you for the application xD
Dear Americans,
It's pronounced "SOL - DER", not "SAW - DER"

'MURICA! screwin' up your language since 1776.
Inquisitor Shu then you should have spelled it with an L!
_oh wait, you did_
It's always so pleasing to watch theses videos
i wonder what someone would think just seeing Wren walking down the street pulling along eight people on charger cables. like an overburdened dog walker
wren: i have studied batteries for years
wren 5 minutes later: kaboom
Damn, the rainy exterior shots might be the best B-Roll in Corridor history!!!
THIS CHANNEL IS DAMN GOOD, SO MUCH TO OFFER!!!!!
You guys are my favorite channel. 8:08 had me surprised and rofl. Amazing.
as soon as you held up the balance leads and said "cut" my entire body tensed up and I puckered a bit xD
Glad to see the Deskercise bike from the job application footage getting used!
I cant finish watching this - WREN! Something something right tool for the job. jfc you're making me anxious!
I seriously love how loud rain is in their studio
I love when wren does stuff
>i hear him says "dont try at home"
> try anyway
>burns fingers
>sticks fingers in mouth

>battery bursts into flames
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
