Been watching your progression over these last couple of years.awesome work man. Just ordered this kit and plan to prototype a case for it that can be 3d printed. Hopefully ill have file ready soon.
Just ordered the complete starter kit. Thanks!
Great kit! I really like your simple way to build power supplies and to explain what you do.
Love the handyman, don't quite know the part name approach. Makes it easier for newbies to buy in. You've come a long way, keep up the good work.
Thanks so much for creating!! Definitely picking up one of these for my Burningman bike build to power my light strips!!
I remember the first prototypes, and I have to say the design is much improved. Good work!
Great stuff as always. My kit just arrived today and is all set to install in a Bluetooth speaker project I am building with my daughter.
Wow another amazing super great video info and analysis from absolutely the best channel on utube you hit this one out of the park again thank you and keep up the good work
This is fantastic, thank you so much. It is exactly what i want to build so started looking for an instruction video and now I've found it.
Perfect great easy way to get started!
GOOD LUCK WITH EVERYTHING YOU DOING..!!
Thank you. I learned alot from you.
Good stuff. Ordered a couple :)
I see things like this and think cool...I can get started with this...I read the comments and think nope... you're not ready.
Jehu you rule brother !!! Change the world one battery pak at a time..God bless you bro !!! 24 hour timelapse...yaaahoooooo !!!!
i like your attitude. keep up the good work man.
Hey ... Thank you for the video man 👍...there is more available...
Awesome job man
I like it, I need it !
Jehu any progress on the AC coupled powerwall? interested in that project. Have you looked into using a hybrid inverter so you can discharge to grid/charge from grid in one unit?
Awesome
Good stuff from a good company..tryn to save the planet
A few questions for the smart people here please:
1) can these be scaled up modularly to put out enough amperage to power a 3000Watt inverter in an RV
2) How many kits stacked together would you need?
3) What would that cost?
Thanks in advance.
I don't think these would work well without a BMS.
Yes it was only a matter of time before someone made this...........thank you.
I feel the bottom plastic didn't get broken accidentally. I feel you purposely overtightened and broke it for teaching us in negative way so that we'll never forget and do that mistake. Thank Jehu!
Can the next step show how to hook this up to solar
Hi Jehu my friend, maybe you should throw in a couple extra plastic black nuts, in case someone strips one out and learns the hard way...
Thanks for the inspiration and keep on trucking ! (from Seattle now)
very very nice kit for people like :D
That QC 3.0 USB jawn will work properly at an input voltage range of less than 12 volts and more than 24 volts. So, it could easily drain your cells down past 2 volts, and possibly even closer to 1 volt per cell. Just a heads up.
Jehu did mention in this video that you can only use it until the voltage hits 21v, then you have to recharge the batteries. An easy way to disconnect the QC charger would be to unscrew the fuse holder and remove the fuse until you recharge the pack back up to 29.4v.
I ordered one of these to use for testing out all my populated carriers one at a time to be sure they are balanced before final assembly. When I'm done with that I will build it up and use the little BMS and a 100W Harbor Freight PV array wired in parallel as the 24VDC charger. In fact I will use the PV array for the testing and balancing too.
Some of you are asking for how-to's involving Solar. Once I get it all up and running on the bench I will try my first TH-cam video. Things to consider are VOC (voltage open circuit) of the PV panel and the peak output voltage under load. A cold winter morning with bright sun is when you get that and only for a few minutes until the panels heat up. Anyway, I'll post a comment or two then.
Hey cool thing you build there but there are some things you need to fix!
using plastik screws and that typ of connector to get power in and out of your batteries is not really good you should use a metal screw and make sure that it won't get loose on its own by using a securing spacer
Reason: if there is a not so good connection the resistance between the batteriemodule and the wire will be hight and can start to heat up thats the reason you should make sure its connected really good
Please vote up for him to improve the design
Sweet
Read my mind was looking for this exact thing
Great stuff :-)
Salute
14:27 Garcia's "blow shit up" laugh. Lmfao
You will never get safe tight connections with plastic studs!
They lack pressure, so the connector will warm up at some point and get more loose, that means more warm, so you create a fire hazard.
I agree with Frederick you need to show how to change with Solar
Good job loved . nice. I need to get hand s on 10 of this BATT . I am very
Behind on my proto . having problems
Whit the. Running time.
What your video is saying is that we can charge and discharge the battery pack at the the same time, if so that great.
Would you do the kit without the batteries because I know you cannot ship them to the UK where I live and if so how much would it be thanks loving your content
Same here I am salvaging old batterie and need only the pcb thing in canada
Recently, I made a 36v 20Ah battery pack for an electric scooter using 10 x EIG C020 slab cells at £12.50 per cell. Only additional items needed was a BMS and charger. Using C020 cells is more cost-effective and space-efficient than using 18650 cells.
The pcbs are right there on the website in 10x for 90 bucks...
@@ownsenergy4418 yes, although it is not common practice to work on live battery packs like this especially when the cells are removable. Generally, assemble/modify any electrical system after being sure the circuit is isolated (turned off) 😀
I agree about the kit without batteries, so that can be shipped easily everywhere
OMG an iPhone that is a deal-breaker for me... hehe. I hope you can put this back online soon. :)
Hmm... Nice.
Would love to get a few of these but doubt that the batteries will be able to ship to my country (South Africa). The charger and USB quick charge outlet on Amazon also doesn't ship to South Africa.
Theyre called Standoffs
They’ll still take 5V/2.4A just not the higher voltages allowed by QC
@@peterg.8245 What would be the use of this kit if I can just buy a powerbank for around the same price?
@@billadmond9450 this kit is scalable, meaning if you link many together you can power your whole house, or anything.
Great, I’d like one... can you ship to UK? And how much?
Mr. What about c1 VS c2 for these
On May 9, I wanted to order and it is sold out!!! When you will have more?
I bought a bunch of brand new Panasonic ncr 18650b and I decided to make a power wall what do you think the best resistor ohm for fusing it thanks
Hey man, thank you for this video!
Can you ship this kit to Italy?
Nice job- I see board has a fuse - value please? and is there a way (PCB trace?) to fuse individual cells ???
Thanks
Bro, if i take this with me on a plane, the police will be on my ass, or apple will give me an award.
For International shipment (Canada for my case) could you do a kit without the batteries... And/or which Canadian Company would you suggest (branch or so) ?
Can the connector you are using for the individual cell voltages also be used for a balance charger?
I wonder if this would power an old 30V NiMH drill that I have... I might get one or two to test. 🤔
Edit: done!
If I wanted to make one of these and use a AC instead of usb power plug how many would I need to buy and is the configuration any different. My intent is to build like a small UPS for my modem / router for a few hours if possible. Appreciate any feedback
Sold out
Any option for kit with out batteries or some other option
I have ordered this kit but I also have 110 18650 cells and I woulike to try to make a couple of 12vdc battery arrays. Can you tell me where to go to figure out how to do this?
Any issue with putting extra boards in series?
I would like to have an 8S one for LiFePo batteries. I know they arn't as power dense as normal LiPo but its easier when working with 12v projects without using a buck converter.
Yes but those cells are rare and it’s not worth the trouble to develop a system for rare cells
@@jehugarcia understandable
how about a 14.4 V kit!!?
Excelente, vídeo e estou aprendo muito com você.
Gostaria de poder comprar suas mercadorias, sou do Brasil.
will it ship to oz ?
the starter kit that is
You should do a video of how to build a power wall step by step and make a book I would pay you if you can help me out
Been preparing 2 years for that video
jehugarcia you would be helping people around the world
Already paid for 2 kits ....Now waiting it to arrived in Malaysia ..
My purchase was refunded !!! I think the kit can't be shipped to Malaysia .... sad ....
do you have a 12v version ?
FYI, there's also 12 volt variant of this board on Alibaba, but just a question do this boards have any balance discharge feature at all? Or do you have to match your batteries before hand? It seems like that's a consideration when you might use these regularly. Otherwise, it's less labor intensive than having to spot weld or solder (bad idea I know but when you only need a couple pack you really don't want to have a hundred plus dollar spot welder hanging out on your bench lol) packs. Also, with this pack if I need a specific voltage like 12 volts should I get some LDO voltage regulators (I have to use those since my work is with active antennas and switching on shortwave radio is a problem) or just standard linear regulators?
Should it not have a Battery Management System to balance the cells?
so can you double this with the same hardware or even quad triple?
Great project wish I could get it but I see no shipping to south africa thou
Maybe beginners question? ....Sorry, but can we use 18650 cells with button top, in this board or only the flat top cells?
This is really good, is there a 4s version of this?
How about 16s....
Hello!
As you are giving away a few free kits like this one, won't you have to support the shipping costs?
Hi there. Nice project ! I would like to ask you if you can provide a schematic of that module?
Thanks and BR !
Hi I’m really interested in purchasing one of your kits to use for a camper van power wall gaming van will need your help!
Is that a misstatement at 15m14s where you said it's a "70 watt hour kit", its 1S7c arrangement with seven cells in series to achieve 24+v. But the total amperage is the one cell rating of 2600mA, correct? You'd connect multiple sets of these boards in parallel to increase the Amperage available (amp hours).
Can you get these units in 12 volts it kinda doesn't look like you can with these cells as for 24 volts you have 7 cells
Could you tell me how you balance these batteries once you built a board and used it for a couple years
Will these be available again?
Hey Jehu! Thanks for the video. Does the PCB provide any BMS functionality, or does it rely on using the appropriate (7S) charger to limit the charging voltage?
Niko Argeres if you go to Jehu website you can order the BMS pcb that Go's with this pcb
I'd just like to ask some questions, if Li-ion battery holders are available, what are the benefits of spot soldering Li-ion battery packs in parallel? If that's more preferable, what are the disadvantages and/or dangers of using battery holders? Also, does the order of placing batteries matter in these battery holders? Say, if I place one (place one, skip the next) alternately would there be a problem/danger?
On the holder vs spot welding: holders are not ideal where a lot of vibrations are common, especially if you'd need a lot of power during said vibrations. E.g. on electric vehicles. Also, spot welding allows much higher currents than contacts.
Price. If you already have a spot welder
Can I use this system for a 60v electric motorcycle ?
Can I use these to build a 24v 30ah high discharge rate pack for a mobility scooter. How many of them would I need and would I need a different BMS and charging setup? Please any help would be appreciated.
Can this be used to power a 12v bluetooth amplifier board for a portable diy bluetooth speaker???
Man, you couldn't make it more easier, even an old hillbilly like myself can do this.. Now I going to try to make a big pack... How many boards can you add ???
I only have power when I plug in my charger? When its unplugged from the wall the power turns off?
can I get one of these to use with portable 12 volt car radio boombox uses 400 to 600 ma ?
So how to order?
Are they really sold out at this time?
....reassuring to see that I am not the only one that slays plastic fasteners by over-torquing . ; }
Can you add a board w/ 3450mAh batteries also? Or do all boards need to carry same battery mAh?
does the display turn off?
What is the Amazon listing for your charger?
Click on the first link in the description it's on that same page
Qhat is a good 18650 charger that is low cost bit a most options??
When your battery is sparking it is because you have power and attaching a load. Take the batteries out before hooking up to prevent that.
...or...add a switch?....just say'in.
@@eaterofclams That does work but sort of redundant as you only need to assemble once.
Can you series connect the boards I would like to build pack with 54v @ 10amps?
Is there a way for not Vs inhabitants to get these stuff ?
I know you're not a big fan of 12v systems, but if you have 12v gear and inverters, what are the options??... LiFePO4 @ S4??... Can you find it in that cell form??
It's already sold out?
Can this be charged by a 12v 100w solar panel? If not what would I need to make that possible?
