so here's my prototype of the spinal battery this is a fully centralized system it has redundancies safety fallbacks and is capable of delivering large currents to peripherals like the ejectable or retractable Batman gauntlets that I designed never gets old so for those not familiar a peripheral is just a device so this could be a motor it could be a sensor could be a solenoid like with what I've got here doesn't really matter it's just a device that's going to require power that's going to be a peripheral to that main system which is what this will
be powering so if you didn't have a centralized power supply you'd have to have batteries on each device individually which one that's awkward because you're adding more weight to awkward spots potentially but the other problem is having more points to recharge your batteries right if you have a bunch of batteries all over that's a lot of different places to charge up every time that you've used something and then additionally the larger problem is that if I needed something like this guy this is a solenoid that draws a lot of power for a short moment but
to have a battery that Supply that I'd have to have a pretty big battery which would be quite clunky it would make this big awkward to move and vulnerable so this power supply is of course near my center of mass so it's a lot easier to move with this on it's easier to protect this right here I can put more heavy armor on it and things like that cuz it's on my back so by having this one device as well I'm allowed to have a lot of different redundancies different chips in here to make sure
that the central power source can be damaged it'll switch power to the other columns whatever it needs to do where you might not be able to do all of that logic in every single battery you'd be putting around on your suit so this little control PCB circuit board back here which is made by PCB way is my regulation chip it basically supplies a regulated 5vt power supply for certain peripherals that need that if they don't want to run off of the typical 12 or 14 Volt Vol power and it also splits the power so I
can run it off more easily to other peripherals so it's kind of like a power bus but I have to have other circuitry in here like my dual power dodes fuses and things in different spots which basically I'll have a future chip that will be able to handle all of that now no doubt there'll be questions on the arc ctor this is of course not powering the suit I designed this a couple years ago I just wanted to show it off and it also gives an example of a peripheral again so this is just a
device that I could plug into this guy back here to have it power just like it Powers my actual Batman blades here so the Batman suit is not going to have an arc reactor I'm trying to have everything in the suit be actually functional as this is my interpretation of what an actual functional bat suit in the real world would look like so now onto the actual cellular composition so by now I'm sure that you're thinking can these are just explode are they going to combust if you damage one of them the answer is no
so a lithium ion is the typical Battery Source that we use for cell phones electric cars use them they have phenomenal energy density but they are prone to combust can absolutely explode and they're very dangerous so I didn't want to actually strap that to my back so these are actually lithium iron phosphate cells they're 50% lighter than lithium ion making them fantastic for a wearable doesn't weigh nearly as much and it's literally incombustible these cannot catch fire you can damage them puncture them whatever it's not going to pose a threat to the wearer now on
top of this they can actually be discharged to 100% as well which is huge so a lithium ion you can't do that it'll actually damage the battery but by discharging 100% what I mean is if you take a battery that's 12vt battery you know fully charged it might be 12.8 or 13.2 or something and when it's dead it's actually like 11.8 or along those lines voltages are not constant on batteries they're always going up to down now full discharge would be bringing the cell to almost zero but the lithium ion phosphate composition is actually allows
these to go all the way down and you can recharge them the way back up and then on top of that these tend to have four to five times the lifespan of a lithium ion battery the only trade-off is there's slightly less energy dents which is totally fine so this is the clear winner for battery chemistry for a wearable power system so one thing that's important about that 100% discharge if I wanted critical Safety Systems sensors or other devices to run well below this thing's dead um system capacity I totally could so I could have
systems that run on five or 6 volts that could continue to run even after all of the other devices that require 12 or 10 volts have been totally dropped offline so I could again have those critical safety systems that run on Lower voltages run for days on end and not harm the batteries by letting them run on it so the whole point of a Batman suit is it has to be for combat it has to be able to take damage has to be strong so we could easily put armor on these to protect these I
picked circular based cells and not flat ones because a circular cell no matter what angle you hit them at it's distributed evenly where a flat surface of course if you were to hit it in the middle it's much weaker there than at the ends and then regarding the redundancy one column of these could completely drop off line this could be direct damage it could be a broken wire it could be even worse a short but the peripherals will see no difference in voltage they'll be able to continue running as normally because the other will seamlessly
take over the power supply for the system I do have this Automotive heavy diode back here that's a dual split diode and essentially that's preventing both streams of current from being able to go the other direction back into the other cell set so the cells are totally isolated until outside that diode where they've been merged and that's where you're able to get that steady power of 14 volts to all your peripherals the only difference is that the max power output of this thing is about 14 amps in full capacity if you were to drop one
of those columns totally offline then you'd basically have a Max current draw of seven amps so what that would mean in practice if I had other peripherals let's say a grappling hook or something that took a lot of power it might not be able to run on its own or it might not be able to run with other peripherals also consuming a lot of energy like if I was using the activate both solenoids on both blades and firing some other mechanism then you might see the current get saturated from that one cell and then the
system bottom out but regardless this will do its best to make sure that all your systems are powered even with half of it being totally destroyed it continues to operating as normally as possible and then of course I did sew up this harness here I was actually originally making multiple degree of Freedom hinges that would connect each cell together because the thoracic spine the upper portion has fairly limited flexibility but then I started thinking like a strap is even more flexible more comfortable and it can take hundreds of pounds like if you get military nylon
so I decided just to strap them all to that so that it's quite flexible and nylon of course is impact resistant so with nylon if you hit it with a hammer or slash it where it doesn't cut all the way through it's going to continue to behave totally normally for a system like this whereas if you had a hinge then you smashed it it might impinge the hinge from actually moving and cause other issues so I decided just to go with sewing cuz that is a lot stronger there and again it does provide for a
lot of natural motion and this battery set is extremely light so it really doesn't feel like I'm wearing anything back there I could easily run jump do flips whatever and it's not going to get in the way of that now I do have prototype version number two already well in the works I've got a lot of designs and things built for that I've revamped the 3D models so that they've got stronger strap support and other details in here for cable management and ensuring that this system is more organized and places for fuses and other things
like that for again more redundancy and safety additionally I've combined all the electronics in here into a single PCB which is currently being manufactured by PCB way as we speak so if you have your own circuit boards and things like that and you want to do what I'm doing with them I recommend going through PCB way cuz they're always who I go through they're fast they're cheap so if you want to bring some of your circuits to life I recommend going through them so do click the Subscribe button if you want to see my version
two when I finish that it's got a lot of exciting updates and is made to look a lot more aggressive and Polished than this current model is and the next best way to support my Channel for free is to just leave a like below or drop a comment I love reading your guys' comments I have email notifications set up so I can read every single one whether it's a question or a comment on something or asking for a future project that I should look at or research always appreciate you guys' responses this is an active
