Very nice!
A couple observations:
1) You could likely get a fine-tip Sharpie to fit through the holes.
2) An Oscillating Multi-tool set to a lower frequency -or- a Dremel with a cutting disc would likely make cleaner cuts on the box.
Thanks for all the great DIY's!
you don't need to mark so accurately with the way he built the design because he just uses self-taping screws.
Would be easier to just supply a pdf with marking holes and through-bolt the plate to not rely on the little self tappers.
@@Rrevo I think fine tip sharpie would be easier really
It's pretty impressive that the BatteryGo meter survives being plugged in the wrong way!
OML that is the sickest build ever!!! Seriously your internal design logic is on point!!!
thank you for finally coming out with a simple build for myself that is visually impaired that I can put a kit together and just have someone else cut the box for me and assist with the putting it together.
I'm super excited to see the progress on the Inverter-board for the Makita box. More details soon Jehu!
Quite enjoying the evolution of your skillset and how simple you make it seem to create these solutions.
Looks great. Thanks for documenting the process
Super slick and well thought out.
Not bad..gives me a few ideas but I would put a plate on the bottom of the batteries to secure them. Like you have for the charging board so they don't move around during assembly and transport. Then I would move the display and usb ports on the front rather than the top so you can use them while cases are stacked on top.
Cool Build, Id add some spacers when you secure the screws through the box to the battery.
Very nice idea, great solution for the unused boxes.
Maybe a idea to make printable drilling/cutting templates available.
Nice. One of these days I will build one out!
DeWalt/Craftsman boxes - PLEASE!😁😁 Thanks for all the great info and what you are doing for the DIYer!
Those boxes are looking good
Awesome build, thanks
Makita systainer lock system is terrible, no one want open it frequently. This is nice kind of use for it. :)
OMG, they are so bad, they are not good brand new, but after a few weeks on a jobsite they get very bad. As a carpenter don't think I have weak hands but the amount of time I've hurt my fingers trying to open/close these is like EveryTime! 😄
The latches get easier to handle when they are super old and worn out (if the box survives that long)
Try some wd40 on the locks. Thank me later
@@Spinedesign I was throw that crap to trash and now I use normal nonstupid systainers... :D
Thank you providing this type of product to Americans
Jehu getting used to having a camera man lollll
That is really cool.
I like your videos you come up with some neat stuff.
Great work! Would love to build something like this but inside a Tanos Systainer rather than the Makita box and also have some 120v outlets on the outside.
I enjoy watching your videos, as my doughter enjoys doll house videos!
This is so sick! 🙌🏾
Very Cool!! Love it.
absolutely brilliant
Great stuff, only thing i would change is USB A to USB C!
Dope, super excited
Looks great… Wonder if it would fit the Milwaukee stacking system.
You should make the connectors go through the lid and have a female one on the opposite side on the bottom so you stack them to connect them up
Fricken Brilliant!
Great work 🤘
Jehu...I Love to watch your video's every time I got a good ideas from it's. May Lord Bless you more.
Brand new ..lol the box said 2016. No worries... great video Jehu.
I think the camera guy actually did a pretty good job pretty good at close-ups when you need it
Neta que you're inspiring. I mean, I'm scientifically inclined, but for some reason anything doing with electricity I'm lost. I like it and interest me and want to do it, pero I just feel in a whole different world, I feel like I'm not capable of doing it. I've seen some of your past videos and remember seeing the solar power bank you made to help Puerto Rico, and wanted to do it myself, but I feel won't be able to. The same with your VW van , id like to convert my car into ev but don't think I'd be able. You and Rich are really talented, and to be honest, I feel like I'm just wasting my intellect as the days go by. I'm really proud of you and what you're accomplishing even though I don't know you. Vamos para adelante, sigue con la cabeza en alto y la mirada hacia adelante. Primeramente Dios, todo te saldra bien. Dios te bendiga.
Very nice!
Brilliant!
Sweet man!!
would love to see something like this for greenhouses (so, environmentally sealed) or such where I can charge them via solar. is that going to be part of something you'll do in the future?
Genioooooo seras mi idolo de hoy en adelante gracias por existir
You gotta design one for Packouts!
I really really enjoyed this build. Is there a way to maybe give support to the board? I was worried the board was going to bend of crack when being installed
Thanks again.
bro nice work enjoy and thanks
Awesome!
In addition to the follow up charger/controller box video, would love to see another build with a different,more common box system like Milwaukee Packout.
Hello my friend, I have some tips. I have experienced the explosion of the USB module, so I personally do not recommend installing a usb module on the battery pack. You can reserve some XT30 or 60 ports for external charging. I highly recommend the SW3518 chip module I am using. It can identify all types of fast charging protocols on the market, and the power supply is up to 100W.
And please share 21700 7sPCB 😘🙏
be neat if the connected when stacked.
THANK YOU FOR YOUR KNOWLEDGE, ARE THE COMPONENTS THAT COME OFF THE RECYCLE BATTERIES REUSABLE?
This is great. Can it work with lifep04?
would it not be work to have a metal file? I'm sure they are reasonably priced and would be worth to have so that you don't have to work as hard to cut the plastic. but then again I don't know if you prefer to just cut and rough fit in.
Well that's fantastic, but you failed to mention how you charge the unit after in use? This is a cool unit and I can see its use in my service truck at a 14-18 volt compacity.
Oh, and a Dremel would work perfectly for these needed cuts to the box
I have been looking at the Milwaukee pack out. I'm curious if you could get the board to fit in one of their modules
My man, this is NICE! Do you have a mailing list for when the kit is back in stock? I have to have this one, and how difficult would it be to change it to 48v? 24v is fine though, I can work with that. Nice work I love how neat and clean that goes together, fits perfectly! And I love how easy it is to change the batteries out, so this will last forever as long as you replace the batteries when needed. I might need two kits, one for my dad on fathers day..
If you parralel the batterys 2 boxes they need to be around the same voltage just like the cellpacks
It is cool. How do you charge it? It should have a 110 input to charge...
very nice...
Neat idea Jehu - but why not put the screen, on/off and USB sockets on the front so that you can monitor each individual battery even when they're stacked.
You can, that’s the beauty of diy
Need more 12v systems..
Now u finally listening too yo boy!!!!
how do you charge this guy. Do you use the same output port in the back to charge? If so can a second port be attached in the back to discharge and charge at the same time or is that not possible?
Thats a slick design. Do you charge it through the output plug? Can it be charged with solar?
From the looks it would be charged via that socket yes, if you wanted to use solar i think you would need a charge controller to act as both mppt for the solar side and to ensure correct charge current/voltage for the battery. wouldn't mind seeing him design a charge controller box aswell for this series, kinda cool concept of the stacking/interlockable boxes.
How is this 7s with 5 packs again? I must be missing something
Beautiful setup. I have a question about heat buildup, would an option for ventilation be wise? If this is used in a mobile environment could mean summer and winter conditions to adjust for temps ?
Nice
Design and build a rack system like they use for servers. With hot swappable battery packs.
Any recommendations for a 7s 20 p pack Bms using 2200mah used modem 18650
When will the smaller Makita box kit be available?
Hi there, great project ! Is there a way to get this kit outside of the US ? Can I plug it in the solar input of an Ecoflow delta 1300 ?
Are we going to see any more improvements to this kit?
Will the 20 cell ninebot internal batteries fit in those stacking toolboxes? That seems like another great portable battery option if it works.
Not this one
When will these kits be on sell?
the saw is 36v 5.0Ah
Hi Jehu, since this design is sold out in your site, will you share the PCBs to public so we can order them from a PCB fabrication facility?
sick
will these ever be back in stock?
hey i liked the battery box verry cool!
i am doing a research on this type of mods to make me a 36v battery pack for my makita cordless mitersaw.
how about you teach us how to make one at 36v with a pcb to suport it?
slick
Hell ya 🔋🔋🔋🔋🔋🔋🙌🏽🙌🏽🙌🏽🙌🏽🙌🏽🙌🏽
can this setup be done for a 48Volt variant ? it would be amazing to hook it up to my APC that has the option of hooking up external battery to it.
@jehugarcia When do you think you will be coming out with the top Box you showed at the end of the video?
And you charge the box how?
Sold out already!!
Mano, that thing looks so nice! Too bad Li batteries do not ship to Puerto Rico.
How about cooling, how they hold with heat in constant usage or with charging? Heat can't escape that box
Install a fan
I like the modular design of this, but do the BMS have enought balance dissipation for all of those cells would be interests to see some test cycles to see how balanced it keeps across all the packs and perhaps some themal imaging to see temps while both charge/discharging. and was the ouput Fused not sure if you mentioned that?
Problem is everyone’s cells will be different, some will use new some old.
@@jehugarcia Thats very true I can appreciate that but I think tests with the cells you sell would provide good information on what could be expected if parts are sourced from you and if you provide the cell specs used then if people do wish to use different cells at least they could then match the capacities for similar results. I think the main takeway is that even with recycled cells the thermals of the design work and the circuit board will keep things balanced over time so peace of mind. Its more work for you I know so understand why you are leaving these tests to users but it does make good content and may invite design changes if issues are found. great content though love the discussion it starts. 👌
Are you still going to do another video with the inverter and charge controller in another box. Maybe I missed it.
I don't think there will be a continuation on the project as the kit itself has been sold out for a while. I emailed them asking about it and doesn't seem they will be restocked unless you are wanting these in large quantities.
I really wish he would do that video, I don’t have the patience to figure it out myself.
Is it safe to run the usb plugs on 24v and not step those down to 12v?
Where does it charge?
How would you charge it?
Can we talk about how to add a charge controller and charge with solar?
That kit is almost exactly what I need except I need a LifePo 4 set up I have 32650 cells for a 24v system design. The tool box is perfect for my solar set up. Since I'm using it for a bus conversion project and battery storage is becoming a headache but the boxes alow me to stack. Ok so question is how can I do the same with the 32650?
You design it, like like I did
@@jehugarcia Can I buy your boards with a different BMS?
Looks like you've just made them non-stacking when you put that control panel on the top.
They stack just fine
@@jehugarcia better design might be to put the control panel facing out so you can use each of them while stacked.
Curious, approximate cost of this build?
Very, very nice, BUT, how much did you invest in the parts, and then put it all together yourself, compared to getting something comparable already built?
Can you make one for me ?
Dude I hope you make millions you are definitely helping me get my solar charged project built
LOL I dont know why I even bother to watch when there are never any products available. Will look for the DIY parts list video to get the components list when thats available.
What I need is 110V to run Power tools on a Job Site
What's the total cost to build this?
I may have missed it but what is the Kwh capacity of the toolbox kit when it’s all assembled and charged up?
Depends on the cells. 1.7kwh-2.2kwh
@@jehugarcia Thanks! About 2kwh is fine for my purposes.
