Glad to see you and an update. I want to thank you again for getting me to try the 18650 batteries. I now have 7,000 cells in my battery bank. Knock on wood,but I haven’t had any problems with anything in my system. I haven’t even found a single cell that heats up. My system has been up for over 5 years and it’s nice to not have a power bill anymore. I love your setup, and look forward to more videos.
Great to hear! Remember just because it hasn't, doesn't mean it wont - happy 5th bday!
I would really like to see more detail about your bms. Overall one of the cleanest diy installs on TH-cam
Fleshing out some ideas, hard part is getting those details accurate. Another idea might be to do a stress test on the BMS- like capacity test a 25kWh battery with the BMS alone!
he has videos about the bms. there are many on youtube
Gratuliere... Und danke für deine viele Freizeit die du hier geopfert hast..
@Enny W - thank-you
Thanks for all your hard work. Amazing battery build. I never would of started my own build without your videos.
Thanks buddy! Good luck with your project.
Great to see you again Pete congrats on the award. Well deserved. Thanks to you I am now up to 7 packs of 80 cells.
Thanks for sticking around :)
Congrats on the 100K subs👍🎉 and the completed battery build 🔋 can't wait to see the capacity test🤩
Coming soon!
Congrats Pete, wonderful pack and achievements!
Thank you kindly!
You are the reason I got back into batteries! I love your content. Keep it coming.
Thanks Sam
Congrats man! Glad to see you back. You were my main inspiration to do the same at home. It all started in 2015 when I was searching what to do with an old laptop battery pack when I came across your video's :) Now I have a "small" 560-cell, 4.5kWh 24v system running for the past 4 years and it's been great! Kudos to you.
Thanks buddy for sticking around !!
hi @Phikzel are you able to cycle the 4.5kw daily made out of these harvested cells from dead laptop batteries, let's say 60% use everyday, or are these for backup purpose only ?
I am asking this cause I want to build one for my computer that runs 160W average when working,
You can easily cycle 20kwh per day, my 6 yr old house battery made the same way cycles 20-30kwh per day happily
Did you use 3.6v 5.6Ah battery?
A thing of beauty.
My hair, you're taking about my hair right ? 😂😁
Don't know how I missed this, but I'm proud of you Pete - you've really made a difference and had a positive effect on Humanity,
100,000 subs well deserved and overdue!
Thanks buddy!!
Congrats Pete, You worked your arse off for this
Thanks buddy
I only started watching your videos as it addressed the Vanon battery issue. Some hours I've now finished watching your battery build. Whilst I have no desire to do it myself, I found it very interesting. A little disappointed with the last battery retention bar, but imagine if given some more time you'd come up with a more refined remedy. Well done. Enjoyable watching 🙂
Thanks for taking the time to watch some of my content
💥Congrats Man!!! Love the Battery Build! Nice a CLEAN!!!!!💥
Thanks buddy
Congratulations on the 100k subscribers! 🙂
Thank you! 😃
Congratulations 👏 🎊 💐
Thanks a lot
Great video as always Pete and a big thumbs up for a detailed video on the bms etc....
Thanks Glenn, upgrading my workshop roof insulation at the moment, then have one or two others planned but given how much effort went into this one and how much youtube love it recieved. I'm heading back to old school peet and just ripping them out with out too much due care lol
Congrats Mate!! Great work
Thanks a lot!
Congratulations from OffGridInTheCity!
Thanks buddy!
Congrats on 100 000subs!!! and another dream build for me:) by the way big thanks for links on netherlands batterys...
My pleasure!
Hey mate, great to see you, it's been a while. Congratulations on 100,000 subs!! I reckon I'm subscriber number about 30 ish? Looking forward to your next vid!
I'd recon you'd back with the first handful of active subscribers! thanks buddy
Congrats a 100k+
Such a awesome build video. Happy it all worked out into a nice completed build. :)
If you can't connect it to the grid, you could just harvest extra solar to run the car; and use as emergency backup. Regarding OCD, think those wood braces look a little naked. ;)
Yeh I think it'll need its own video feature to fix that wood lol - but it was cheap and worked
Congratulations mate , 👌
Thank you so much 😀
Nice job Pete!
Thanks! Mr Green!
clean build ! i love it
Glad you like it!
What a great project. Unfournetly I have no idea about electrics I guess I have to watch a tons more videos for a bit of knowledge.
I find these types of projects have been great to learn, touch dangerous and doesn't come with out risks.. but hey - learning to drive is dangerous and millions do it every year so learn as much as you can and enjoy the journey..
Thanks for the information
My pleasure
Glad to see it's finally done!! Very nice work. I would have used a piece of strut channel for the battery support though rather than the skinny piece of wood lol.
Oh, and when do we get to see a capacity test?!
I'm going to 'try' do a capacity test with the BMS :P Is the strut channel non conductive?
@@HBPowerwall No, it's steel - would have to use some sort of padding. Maybe adhesive neoprene foam or something (the dense kind is hard).
defiantly look into that.. or at the very least something stronger than wood..
Congrats mate!
Thanks bud
Still love the 18650. A true diy lithium battery. Tx Pete. Keep doing so.
The love is gone here lolz
Congratulations well deserved
Thank-You
Fanatic of the channel !
Thank-You
Nice to see you get 100K Peter.
Thanks 👍
Average Joe Advert! WOOO!!!! :D congrats on 100k subs!
AVERATEJOE!!!!!!!!!!!!!!!!!!!!!!!!!!!!..... and TY :P
Congratulations for the 100,000 subscribers.
I would also Iike to see how you have done the BMS.
Thank you for your time
I tried to cover it off fairly well in this video from memory. Just too much effort to do it in detail sorry
This is great
I did enjoy the build!
Love you,
From Banglasesh
Love you too.... *feeling warm n fuzzy....
Congrats seems impossible until it happens
for sure!
Hallo gutes video danke dafür 👍
Would love a video with more detail about the fans, breaker, batrium control, etc!
the whole playlist is here - th-cam.com/video/PenPYwa00CA/w-d-xo.html
I feel your OCD pain brother.
Thanks Grub!
Lol at the mcm stool :)
i'm a sucker for other tubers merch!
I would love to see the detail on how you set up the BMS system, how your monitoring system works, what equipment you used, etc. thanks!!!
I'll see what happens, doesn't seem to be much interest unfortunately
@@HBPowerwall I enjoy your videos. Congratulations on the silver play button! That’s super cool.
Thanks - it's always good to get feedback..
Nice build mate. Should you trigger those fans off thermal sensors though?
Yep, three off them remote, one on BMS & another on the shunt, or battery voltage, or time of day, or all of those events at once lol
Verry good
Thanks
@@HBPowerwall same²👍
Hey I just talked to you at a public EV changer today. Had a good chat about your EV. I was surprised you were not so keen about the whole home battery storage idea.
oooh hey Tony, it was the source of the batteries that supprised me ooh and someone picking me out in public lol
ooh and made a post a bit earlier about meeting you :) Would have stayed longer to chat but it had already been a super long day starting at 1am and still hand over an hour to get home. th-cam.com/users/postUgkxXV8dfu8hWkB8H1AcILZlrWU7y3EMyHH8
I hope you will not forget to set the relay back to the critical fault :)
Yes that has been done already :)
looks nice! congrats on the 100.000+
Thank you! Cheers!
Almost as good as peanut butter and jelly.
:P
I give you an idea. Test the interaction of two types of connection connected cells at the same time. Parallel and serial. with two BMS modules. I'm sure the result will surprise you. 4 in series 4.2x4=16.8v (3000mAh) + 8 Parallel 8x8=4.2v (24000mAh). You can increase the amount cells, but the dependence will be different, but it should be the same. I am sure you will like this test.
Question, I'm doing same configuration of 4x80 18650s packs and spot welded nickel sheet on top/bottom. I had issues with next step, soldering down the solid copper wire to the nickel sheet. I was curious if possible to just sandwich the packs to each other to gain 12v...Instead of soldering copper wire on every pack and just smash them together. 😅
You COULD I guess, low power draw you likely get away with that sort of lack of care. I wouldn't, these batteries are dangerous enough with out adding a hole heap of cold joints
what?!?! i swear you should of had 100k subs long ago! D:
I did like 5 months ago, can't you tell by the length of hair heheheh
Congratulations I think one day I can also visit that but first I am making an e bike but there is no original 18650 available in my location .
Best of luck with your battery build
I'm building a 25k system. Looking for ideas as I go to help me with my build. A fascinating and exciting project. Watching these videos are inspiring.
Good luck!
Wow....this fantastic!!!
Forgive me for asking....I am not very sharp with these subjects....What happens if a cell or cells go faulty? Can a rack of batteries (that contain the faulty cells) be easily pulled out in order to gain access to them?
It's a pain in the ass, but don't take too long considering how long it took to build :P
You've done brilliantly. I just wish I knew more about this technology. It is very daunting for me. Superb work on your part.
Parabéns
Translated to - Congratulations, Thanks @Manuel
Hey bro, what do you think about the lithium phosphate batteries over the 18650 cells?
Never used them but these days there are a bunch of better choices if you have the funds than 18650s
i will never get used to people drilling and showering metal shards next to exposed electronics
Most were covered BUT i did start with it uncovered, then panicked, it's a huge drawback of trying to film, build, edit, produce & manage a one man show.
how many 3.6v cell packs can the batrium monitor? im currently starting a 840 cell 24v battery and im kinda curious about batrium. but i want to add more modules later so im unsure if batrium is right or if i should go with another bms
oh and congrats on 100k! i know im late but ive been a lurker so i think its ok lol
well this one does a great job at this size, using longmons would be better again.
Hi again. What internal resistance of whole battery ? For a reference my from lion 323Ah prismatic cels (s14) is 5.5miliohms.
never measured it..
What voltage do you leave your cells sit at for the self discharge test? Most of the datasheets I've read show that 30 days left at 4.20V is going to knock off a fair bit of capacity. I don't understand why people don't use a lower voltage......leave them at 3.60V and they shouldn't self discharge at all. If they self discharge even a little bit then they are no good.
4.2, let them sit for a week or two to 'level off' take the voltage reading after that week or two and check again in a few more weeks, the higher the voltage the faster i'll loose charge so if you did it at 3.7 v it would drop a little slower...
Do you have a link for the batteries terminals?
Black ebay.us/WsDFcK
Red ebay.us/Rlnqip
Are those the ones you were referring too?
Would you elaborate on the Australian regulation you mention that restricts you?
This like is vague and misleading to a degree but it'll give you the gist renew.org.au/renew-magazine/solar-batteries/new-battery-installation-rules/
where did you get the batteries?
These were from a local school
Ive made 6 packs , then got sidetracked :) i never got round to doing the rest, my hats go off to you folk who can test and retest and assemble these packs. I might just go with a 24v pack and call it a day :) i just dont have the drive now. And LFP has come down and safer, so this may end up bing a shed power type setup :)
OOH LFP for the win... would make a boring build video but dam 10000% less effort lol
@@HBPowerwall - i know wheres the fun right :) i can always make up a new battery pack for my 10k ebike :)
Interesting that you are using 'Critical Fault (when not ok)' - I was advised this is NOT correct by Batrium.. Should be using Critical Pulse Off (CB Trip) to do the job? Appears to do the same job?!
I received that memo lol Woops...
wouldnt it be better to have some ventilation holes on the control box as it all enclosed that fan is just blowing hot air around inside and not really cooling the ther pcb's!! just a thought
finally someone saw my epic screw up.. remember when I said I should have made the BMS hole larger? lol I forgot to cut the hole for the fans
Me ajuda a funcionar meu sistema preciso de uma bateria de lítio para funcionar meu inversor em 24v
Brother I have one question I ask from all popular TH-camrs but no one correctly answer that so now I ask you about that
IS 18650 cells Bater then Lifepo4 ?
If batter then Lifepo4 then why in electric vehicles using that 18650 ?
Why and where should choose 18650 cell ? If compare price 18650 need more time to build and need more care so why should not go for Lifepo4 sorry my English is not good if possible you can explain that in your next video with complete details
Thank you for always bring very informative videos
Best regards from Philippines 🇵🇭
I went 18650 Because used cells were free and I was broke. Ever again !!!!!!
Never again!
@@HBPowerwall understand so it's means you definitely going to replace in future with lifepo4 am I right ?
i'll keep these going as long as it's safe, but that time I should have moved on to a new home and I can look at different options.
Hope you been doing well man.
My 400Ah one you helped me with has been going strong over the last year and a half.
Make sure up flash the new wm5 firmware, it is way better and the cell voltage smoothing takes away critical voltage spikes that kept tripping mine.
I'm 5 versions ahead of public release lol
They grow up so fast. (Your son)
They sure do..
Why don’t you make high voltage grid like batter pack it will bhi easy to charge
There are a few issues with that thinking - safer, more legal, less expense to go LV
How many watt hrs is your build?
25.04 kWh tested at 500watts
Hi. What a regulation? You told at begging of video? Thanks in advance?
I"m assuming you're asking about the Battery Installation Regulations. they are the Australian Standards to keep every one safe
like to see some real world tests
Trying to work it out with out going outside the new regulations
Não tenho enprego não posso compra as células 18650 🙏
Ocd... I want it to look professional... also scrap timber 😭 The art of compromise right there.
I needed to finish the thing and was honestly scared the cells would fall. 😂
@@HBPowerwall i work as a software engineer. I feel you with every fiber of my being...
No I look at it and really cringe, might have to sand them and stain them or 2pac them the same color as the cabinet
@@HBPowerwall Im just saying i know the feeling 😁 you pour your heart and soul into a project and everything looks great, but you live with the knowledge that somewhere, there is some small but super critical component that made of scrap, bits of string and used gum 😭 That is software development in a nutshell.
If you wanted the shunt inside the box, why didn't you just use a bigger box?
Didn't have one 😂 also next size up didn't fit well..
@@HBPowerwall I think the OCD is starting to show through. Now I know why all the batteries have the same color. 😁
Gota make it youtube sexy, no use making a battery that looks like a clown has thrown up all over.
@@HBPowerwall It's all youtube sexy
What is the regulations stopping you from putting it in to service?
This extremely basic and sometimes misleading article will point you into the right direction - renew.org.au/renew-magazine/solar-batteries/new-battery-installation-rules/
Or.... get a bigger box 😁
That’s what she said 😆
im like you bro, but without money for build my baterry
I built this cheap over a long time! And could have done it for half again you just have to think out side the box..
IDK why you are boxing up the stuff that you will invariably be tinkering with at some point.
Cause I wanted it to look good! But your very right, in hindsight I wouldn't have done it that way.. But that's find this is a learning process
First LOL LOL LOL LOL LOL LOL

how many amp hours of storage
if it isnt above 1000aH it is of no use to me
25kWh ish...
@@HBPowerwall kwh is not ah
kwh changes as wh is used...because voltage changes as you use the battery
but.....520.83aH is getting there
thats according to all the conversion charts
that is enough for a small off grid cabin with very little AC electrical use
my home would need 2 of those to run off grid without using the generator at night
yeh but ah changes with voltage.. so it's 500ah at 48v give or take..
@@HBPowerwall if you are using 1 amp at 48 volts, you will still be using 1 amp at 47.9...47.8...47.6
watts will change w=v x a
so 48v x 1a = 48w
as 47.9 x 1 = 47.9
as 47.8 x 1 =47.8
because battery voltage goes down as you use amperage at the same rate
The nominal capacity of the lead-acid batteries is given for the 20h discharge - 100 Ah lead-acid battery is able to provide 5 Amps for 20 hours.
it is always said to look at your amp rating to know how much battery you need to run in a certain amount of time.....no battery company or inverter company tells you to look at watts
they tell you to convert watts x voltage to get the amperage....because watts change as you use voltage
inverters may put out the same AC watts, but DC watts will go down, but both AC and DC amps wont change if what you are using is using 1 amp, it will always be 1 amp for both
The batteries are too tight. They only tight them like you have with liquid cooling.
or mr mechanical engineer you build the battery to actually suit your needs and the capacity of the inverter and there isn't a day in our Australian Summer they will over heat.. lol Also BMS with programable fan control, temp sensors, shunt trip so if it does get even warm it'll self protect. Then if that fails and it all goes south the 2mm steel 65kg enclosure will just glow a warm red color till my fun little time investment melts into a puddle of metal. NOW should that happen I took the time to install a HD camera that records in 4k 24/7, I'll upload that footage to youtube and 10x this videos income.. win win i'd say... but i'm just a little DIYer havin a crack.
13:32 Eye protection BOZO !!!!!!!
BOOOOO i don't live in that world.. had my hearing protection in, that'll do..
the added timber makes your beautiful box look ugly!
I can't agree MORE lol
Nagh.even Mercedes-Benz have wood :)
Your fan grill holes aren't straight. Can't sub.
I feel you brother... I'm thinking I owe the world a personal apology, and start over with the entire project - delete my channel and become an old order Amish carpenter..
If mrbeast gives him 10k usd he would spend it on 18650 batteries
Nar hookers & beer - :P
