Thank you for keeping me honest. I've been delayed by a few other projects, which have taken longer than expected. I've dusted off the AZ-Touch and will look at finalising the code and then releasing an update as soon as possible.

The cells that were removed ended up in a number of projects, for example a remote telemetry unit that was solar powered.

Greetings Eric. Thanks for the feedback, apology I didn't include the wiring. See the links below to photos I have taken, I hope they help. imgur.com/a/Eo1UcbE The red wire is vcc and the black is gnd, with white being data.

Constantly , maybe is antipodean thing? Changed to bus bars occasionally later.

Extremely unlikely. The design of the packs is proprietary and utilises Mitsubishi components.

99.99% no

It is possible yes, but it would be better to replace the stock led with ws2812b

But if you only want to use the unit as light indicator without air quality measurement then there are far better options then that.

I can help you to build something. Its really easy. The speaker light Shows up in home assistant as light bulb and you can control it like rgb light bulbs and make automations. You can use this unit for air and add led yourself and I can provide you the Code. Actually I am thinking about doing that since I have led here. Then you have air measurement and light as light bulb in home assistant.

But the led on the Board unit itself are no rgb. They are 6 Single led 2 Red 2 Orange 2 green.

Greetings, Right now the server is running Proxmox, with multiple virtual machines, and several containers. having the additional CPU cores was the target of the upgrade, and the 7551 EPYC CPU doesn't disappoint. If there's anything else you'd like to know just ask. Thanks, Mark

Hi There... I did add the code as explained here www.home-assistant.io/integrations/bluetooth_le_tracker/ but it appears implementing BLE presence tracking is not as straight forward as I first thought. I am continuing the journey when time permits, and have purchased a few iBeacons, but nothing concrete to report. I may end up doing a video to explain my journey as it might help other folks.

Do you mean in esphome Code ?

Hello, the UPS is silent while running normally, and when the power fails the inverter is most likely louder than the fan, but not extremely loud. Hope this helps.

@@gregoinc4987 Hey, does it produce any hissing sound or something similar? I've looking for something quiet, and current APC SMX model always produces hissing sound, it's unbearable in to be in the same room as UPS.

@@rimvylo No hissing sounds that I've heard. Like I said, it is silent until the power drops and when the inverter kicks in the units makes noise.

Don't know about the 40, but the LEV50N is max 300A continuous discharge and 50-100A max charge rate depending on temperature (even lower at extremes). They seem a bit weak for regenerative braking of a medium vehicle which typically needs 30kW. The Miev is a small and lightweight EV. PHEVs are engine assisted and don't need extreme battery power vs capacity, probably why the Outlander used LEV40. However, that car has battery problems that I suspect relates to the heavy vehicle regenerative braking requirements causing stress. Forced air cooling.

@@robertgregory8964 Thanks for that info, I would like to understand the forced air cooling better, I don't see any gaps where the air could go through. Can you tell me where the air can circulate? Are there air passages in each cell? Thanks!

Hello, where are you located and we can go from there.

@@gregoinc4987 Hello Greg, We are located in Bogota, Colombia but we think that if you have the functional piece we will buy it for you and pay shipping costs, I would appreciate it if you are interested in giving me a quote.

And I'm also bothering you, I damaged 4 4v 50 ah lithium ion batteries, they're from the miev, if you have them functional, could you sell them to me, since I can't find them anywhere in Latin America.

@@bateriasvoltabl6387 Let me see what I can find in the parts bin and will come back to you.👍

I would recommend looking on ebay, as there could be some items for sale.

Thanks for the advice but I have already do that .I hate Mitsubishi and yuasa

lev 50 not lev 40

Hi John, let me see if I can find you some photographs and post them on here.

@@gregoinc4987 That would be helpful

Yes, we have multiple of those units.

​@@gregoinc4987 I would be intereseted in buying one...

@@adrizi13 let me come back to you. It might just be easier for me to put it on ebay. Did you have a price you would be happy with?

@@gregoinc4987 Shipping will also be a topic, because you'll be sending them to Europe.. ;-) i would say around 100 AUSD?

@@adrizi13 No probs... That's cool. Let me put something on eBay and we can go from there :-)

Hello apology for the late reply. The LEV50 can absolutely operate as a stand alone battery. You would obviously need to calculate how many LEV50 cells you might need to make 24 volts, or as close as possible. As with all Lithium Ion batteries, suitable configuration of the BMS is critical.

Grego Inc Ok, thanks. So ... I understood that any way external BMS is required on top of what is inside the module. That was my question.

@@AlexIVVIxelA Hi Alex, some folks are exploring using the vehicle BMS modules, with some success but the configuration is complicated. Other folks use BMS units from places like REC and SIMP BMS. I would recommend you do your own research in this area as there are a lot of options and configurations.

See my other replies... The nominal voltage of each LEV50 cell is approximately 3.7 volts, so you just need to do the maths on how many cells you would need in parallel to reach 24 volts, or as close as possible. As with all Lithium Ion batteries, suitable configuration of the BMS is critical. Recommend a good quality BMS to be safe.

Hey there, not sure I follow your question? The case surrounding the 8 x LEV50 cells is plastic, are you wanting to know the measurements of the case around the 8 cells?

@@gregoinc4987 yes, as well as from cell assembly to the top battery cover

The LEV40 'pack' size is 300mm L x 175 W x 120 D which gives you an idea on size. Re LEV50 I would have to get back to you as we are expecting a new shipment of LEV50 soon.

@@gregoinc4987 This is a "standard" case size isn't it? BEV2/PEV2?

Not sure I follow your question... the cells are LEV40 and LEV50N. Perhaps you can give more info?

@@gregoinc4987 good time! you don’t understand me, the element lev50A is x 175 W, the assembly is laid sideways in the VVB case, when the lower bearing part of the VVB case is covered with the upper part, the cover, VVB, so I’m wondering what distance remains between the assembly of cells that are x 175 W, and between cover vvb. above the assembly there is a ventilation tube in the inside of the case, it looks about 10cm, is it really?. can I put cells of a different size in place of x 175 W, for example x 200 W or x 250 W, will the battery cover not abut? Here is such a question.

Hi Ruudi, thanks for commenting. I can see your point, however once the packs are rendered safe the chance of short circuit is extremely low. I've stripped down packs so many times now and have never had a problem. But I agree, for a person doing this for the first time, every safety precaution would be worth it.

I assume you are talking about 'tagging' like is used by manufacturers in printer ink cartridges? The answer is no, they are just batteries, so they can be changed out. BUT... you must make sure the cells are 'balanced' which ensures each cell in the pack are at the same voltage and charge level.

@@gregoinc4987 Thanks!

See my ebay item here... rover.ebay.com/rover/1/705-53470-19255-0/1?icep_ff3=2&pub=5575378759&campid=5338273189&customid=&icep_item=324031133013&ipn=psmain&icep_vectorid=229515&kwid=902099&mtid=824&kw=lg&toolid=11111

Hi Mario, glad you enjoyed it. If you can send me a photo of the part you are seeking I will see what I can do to help.

I don't have pictures yet. It was just yesterday my car died, then I saw wierd values with canIon. Cells 61 thru 68 were at high voltages (maybe 325V) and temperature censors 46 thru 51 showing 205°C. There aren't any repair shops nearby so its a DIYer. Any help is welcome and much apriciated

What year/model is the EV please?

C-zero from 2011

Hi there, and thank you for watching. When you say LEV50 elements, are you meaning parts?

Grego Inc yes. I mean little blue batteries of what this big batterie consist of, or maybe you know where could I buy whole batterie aftermarket)

@@TomichNaumich Hi again. We refer to the blue batteries as the LEV40 or LEV50 lithium ion cells. Where are you located, as I may know someone that could supply the individual cells.

Grego Inc hi could you please call me perhaps regarding Imiev lev50 cells and or battery pack components (perhaps surplus) I'm building a Imiev based racer 🤘🤘 cheers 🍻 p.s I'm in Adelaide Australia my number 0418899907 👍

Hi and thanks for watching. I have not found an issue with any of the battery packs I have sourced. Which is probably due to me choosing the packs carefully, making sure they are from vehicles with low mileage and have not been damaged i.e. in accidents etc. The LEV40 and LEV50 are amazing lithium ion cells, and can be used for all kinds of projects.

@@gregoinc4987 So is it possible to measure voltage right there on the salvage yard on the power terminals before opening the pack, so you don't buy a flood damaged or shorted battery?

What is the OEM voltage output of the battery pack? How are they configured in series and parallel what is the voltage of each module?

Hi Paul, Great to hear from you. I source Mitsubishi LEV40 and LEV50 battery assemblies via international suppliers to import into Australia. The delay in my reply was due to me waiting for a response from one supplier for a late model Miev pack for you. Unfortunately there was no good news, with Miev packs rare at the moment. Price wise, the pack prices vary due to market demands, and can range anywhere from $3000 to $5000 imported into Australia. Regards, Mark

@@gregoinc4987 Thanks for your videos Mark, Ive got a MInicab MIev I'm looking to repack in the coming years and am getting an early start. (Wouldnt it be great if Mitsubishi Yuasa would sell us the batteries) Looking forward to your next video. ps were the lev50 cells lev50 Ns ?

Grego Inc awesome videos mate! Love it. Cheers for making the videos. I look forward to hearing from you if you have time. (I'm in Adelaide). Cheers 🍻

@@metricstormtrooper Yes, LEV50N pack.
