- I was planning to build a battery monitor, that quickly would show me the voltages of each of the 14 cell groups in my 14S Li-ion battery bank 48 Volt-ish. But I found that I could get a profitionel made one,, and that looked way better than what I could make :-)

For 3$ a month, you get an extra weekly "What's UP" update video. Just for my Patrons. The Support I resave on patreon is all used on stuff to make interesting videos on TH-cam.
My PlayHouse is a channel where i will show, what i am working on. I have this house, it is 168 Square Meters / 1808.3ft² and it is full, of half-finished projects.
I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time. - วิทยาศาสตร์และเทคโนโลยี
Yo Morten I'm very disappointed in you! Don't say it's most boring video ever! It's fascinating and cosy. Tinkering like that is awesome to watch, that's why I'm here!
Hi Michał Szczepaniak
Thank You very much! glad you liked the video, I do not want to over sell it, but am am happy that some of you also like messing with this.
Thank you for watching! :-)
Could be a good idea to keep track of which banks of a certain pack that keeps needing to be charged during maintenance, to help in the future to track down bad cells.
Yes,, I did notices that 3 and 5,, was more difficult than the others.
I REALLY like that Spot welder, its been working great for me!
Hi Patrick G.
Thank You very much! me too,, that is why I promote it,,again - glad you liked the video :-)
Thank you for watching! :-)
Nice video as always Morten
Thank You,, nice to see you in the Discord Chat.
Thank you for your beautiful narration
Hi ibrahim sarıoğlu
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
Hi, nicely explained, very useful video. Have you tried to monitor the voltages of individual parallels when discharging the battery pack.
No I have not tried that.
Just get yourself one of these to charge each cell. CC CV lcd display. I have over 20 of these. Great video.
Mine is just a monitor,, how do you charge them ?
@@MyPlayHouse The link didn;t go through. Just search for 12A lcd dc to dc step down Or boost or buck module.
The 12A with LCD i would use up to 8A possibly 10A (without extra cooling).
They are a little pricey if you need 20x of them!
However this would allow you to fast charge and balance at the same time for a fairly big pack. You also need to buy some power supplies to drive them. They step the voltage down so a 12V supply is fine, you can also use a 5V id it's adjusted up to it's maximum voltage or a 24V i believe is still within the range of options.
If you don't want a fast charging while balancing option you can get one of the smaller modules but never think to use them at their specified output, always go at least 3/4 of the rating. You can get 4A and 5A modules a little cheaper. Also, you can get a much cheaper module which is also CC CV adjustable but it has 2x LED displays, i think it is 4 or 5A
You can get even cheaper CC CV modules which don;t have displays. You just set them up with a multimeter and then they are set.
If you wanted to balance a 20S at 3A per cell (which is quite fast if it's just one strip and not more cells in parallel) You just set each module to 4.2V and then you limit the current to 3A by turning the other variable capacitor i think it is. (They turn and turn many times till they hit the end stop).
They also make an 1800W step up which is great for fast charging larger batteries but that one has no screen.
Some of the nicer modules are fully controlled by buttons and you don;t need to twist any pots or varicaps.
There are active equalizer balancers available
They balance differences of 0.1V in between battery cells at all times
They are not perfect but work
The 0.2 volt, was a bit much,, it would balances out a little bit when it is fully charged.
Try riging up a simple Y-cable for the smart BMS.
I have ordered parts for just that :-)
Is that with your spot welder on level 2 power? (Waiting on mine to arrive😎)
No I think I was using it on 4,, it still did several hundreds welds on ½ a charge :-)
It is what I am looking for but just a quarte3r the size (max. 6s) - have you any units like that ?
I believe you can find that ,,, and way cheaper.
What is the voltage to power that testing instrument..nice video..thanks
It is 5V,, I use USB power.
@@MyPlayHouse thank you very much..
I found an identical display of that instrument maybe they are the same..but this one automatically balance charge the batteries..please check the link if im correct..thanks

Weird how the Ali link shows this cell voltage monitor does not include 16s pack???
Are they very popular?
would this also work with lifepo4 cells 12v 304ah 4s pack?
I do believe it can,, but follow the links and see if they do not write that as well
Hi, where can I find those nickel sheets with fusible rings like tesla's? 13:30m

Thanks and I hope you continue enjoying Portugal
I could've been first...
Yes, go with the gadget that does the balancing for you.
I would really like to not have to have a $55 BMS on each bank,, the $11-14 prices I like a lot more :-)
@@MyPlayHouse yhea maybe just one for balancing a bank when needed.
@@MyPlayHouse It didn't look like all that much work to bring a bank out for maintenance so doing one bank like that every other week would probably work to keep them in shape. Might be possible to have them stored slightly more apart for easy access? I'd say put half of them on the top shelf but I imagine it might not be that fun lifting a bank to more or less head height.
@@MyPlayHouse If you need to re-balance again, then you already have a bad cell in your bank ...
Will this work for 24pcs of 12volts just to monitor?
There are two versions,, take a look.
@@MyPlayHouse i can only see the 1 you have
The fact that you are having to manually charge these batteries...doesn't that mean that your BMS isn't doing its job?
It only balances when some of the cells reach 4,19 volt,, so only when the packs are fully charged. The BMS also protects the cells and shuts the pack down if anything is to wrong.
@@MyPlayHouse Thanks for the explanation Morten. I can see why you are considering a more expensive BMS for them. Considering how much time you spent putting those battery banks together, I can imagine that it would be worth a little extra expense in a better BMS to get the most performance and life out of them. Thanks for recording your experiences with building them. I'm learning a lot by watching!
or you could have gotten a bluetooth bms which you can see all the voltages on your phone.
They cost 4 times as the ones I have now..
Have you tried making / hosting a community minecraft server?
No,, I do not play it myself.. I am on Discord every night with Patreons.
second and i love the video :)
Hi ConGG Gaming
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
It would be better price wise to build 14 X 1S 4.2 volt batteries (15 to have a spare) and then you could use one Daly 14s BMS. The batteries are too small for stationary power. Small 48 volt batteries are better for bikes. A 100amp Daly 14s BMS is only about 100USD$ and will balance the 14X 1s blocks.
Hi Solexx X
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
this is one SHOCKING video
ahh,, there was no shocking in the video,, maybe "That was one well balanced video" :-)
