The 4 pack build i strongly believe is due to manufacturing. They can have just one stock item and then have the 8 cell pack require two. Simpler manufacturing.
Anyone know the max discharge current for LEV40? I've seen spec sheets for LEV50 that say 300A continuous but can't find LEV40. Surely they can go higher for shorter periods too.
I have a 2012 Citroen C0 with Lithium Ion batteries, the cells are LEV50. There are 11 packs of 8 Cells for a total of 88. I am looking for the two cards of the fifth pack which gives me a defect in a test. I don't know if it is possible to reprogram the cards. Hope someone can help me Thanks in advance
Do you have to reprogram the BMS when you change a cell? Do the manufacturers do any nasty tricks to prevent user maintenance or can you simply swap the cells? Thanks!
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.
A lot of folks have had quite rapid degredation of their LEV40 batteries in Mitsi Outlanders. I have wondered if it would be possible to substitue LiFePO4 cells, but that would take changing the voltage settings in the BMS. Have you been able to talk to the BMS and if so, does it allow for adjusting limits, or is it totally locked down?
What are the dimensions of the LEV50 battery plastic case? What is the size of the installation site of the LEV50-8 battery, plastic case, in the air force case?
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.
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.
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.
@@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.
Hi, where did you acquire the imiev battery pack from? Also how much did it cost? I am looking at the cost of buying a newer replacement battery pack for my 2011 imiev. Thanks Paul
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 ?
@@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.
Hello, I"m very interested in these packs to replace the batteries on my homemade electric car, ruclips.net/video/_uLH1N42sdg/видео.html . I need between 250 and 300 volts, and would like to have around 10KwH capacity, with up to 500A peak discharge, all of which seems very much in line with the specs of these cells, using between 72 and 80 of them in series, and they are available here in Europe from the mitsubishi PHEV's. However I have a question- how do they do without any cooling? They don't seem to have forced air or liquid cooling, or even air gaps for the air to go through. Don't they get very hot? Thanks for any insight you might have on this.
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!
It's a little bit scary to watch, at that camera angle, you use this uninsulated T socket wrench ontop of Li-ion battery. But thankfully nothing bad happened. I think it wouldn't do bad to insulate it with some shrink wrap, would avoid a few times dropping the tool onto the battery. I have used even electrical tape. Ofcourse all hobby battery guys cannot afford decent 1000V rated tool sets they are really overpriced but you can make your tools better suited I think.
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.

99.99% no
Where would I find a data sheet for these?
Hi, would you know how cells are numbered from cell 1 to cell 80. Do you count the first cell from the left or the right module?
Can you tell me where to find these cells ??? It is almost impossible to find these! (LEV50)
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

Can the BMS be utilized in a 24v configuration for an off grid system?

Do you think that LEV50 module can work as stand alone 24v battery ? I mean if its BMS could serv cells without connection to the car electronics?
