BetterHelp is one of those sponsors that I'm almost more mad that they screwed up than the actual mistakes they made. Mental health and therapy are legitimately very important, and to have one of the few companies that is advertising services that aren't basically just selling questionable drugs go and mess it up is frustrating. I'm personally not comfortable sharing health info with really any online platform, and examples like BH's past behavior are a big reason why. On your part, though, the fact that you did your diligence to know what was going on with them and make your decision based off that is enough that I still trust your judgement, even if it may differ from my own. Even if other creators didn't know or didn't care about their issues, pretending they don't exist just gives more ammo to detractors and leaves a bad taste.
Even if they accepted their FTC punishment, they still hire wildly unqualified "therapists" and people in mental health situations need a trained professional. To them, paying the FTC fine is just a business expense, not a lesson. I'm happy that you got the help you needed but it seems like your experience is the exception, not the rule. We weren't upset because the sponsor "distracted" from the video, we were upset because you were advertising for an unethical company.

I think they just re-routed it after finding the peltier modules shit the bed while it was in for service on module #4. That's probably why the truck doesn't have the bccm unit at all.
My theory why the BCCM is missing on the truck might be because Via figured out the Peltier modules didnt do anything or not enough to justify the cost, so rather than change the mounting plate they probably already had stocks of they just looped the system and called it a day.

The inability for the charger to balance the modules, or at least some connectors to the modules to do it manually without dropping the whole pack, seems like a massive oversight. On EVs, battery maintenance and longevity seems to be the biggest issue.
The biggest issue is actually a combination of using the right charging method and thermal management. For many bev & phev you really should not rely on fast charging. Most plug-in hybrids can’t even do fast charging anyway. Level two charging is really the sweet spot for most of these vehicles as long as you can find a charger that works and fits along your route of travel. So really the two biggest issues are availability of level two chargers and making sure that the battery thermal management system is working correctly. In my personal opinion, fast chargers are primarily a good use case for people traveling longer distances in fully electric vehicles, and not local around town type travel.
@@markm0000 the electric drive system is just not integrated properly with a throttle control for the gasoline engine. A few more steps and a little bit more time and investment may have seen these get much more success.
To be clear, you’re not wrong. However, depending on whether those satellite boards had any logic on them (as opposed to being just a bunch of mosfets remotely controlled by the main BMS board), that idea might complicate the design significantly. For example, how many cells should be able to be addressed/used when balancing from one module to another? How do you balance (pun not intended) the workload of balancing the module itself as you’re also transferring energy out of it to a different module (this would be an issue when the cells within a module are mostly balanced, and bringing another module up would create an imbalance)? It gets pretty complicated in a hurry, so I don’t blame them for skipping that.
@@jacobcarlson4010 True, but then, at least, have a diagnostics/manual balancing connector available. An un-balanced pack would still require a dealership visit, but significantly less work. All they would do is unscrew a waterproof cover, plug into a special charger, and let it balance for a few hours. Sure beats having to drop and disassemble an entire pack. These are supposed to be fleet vehicles, so ease of maintenance needs to be a priority.
Although I will regret never getting to see that epic vision of a electric super school bus I am really glad he has more shop space to work with now. His other space was starting to look crowded.
@@ThemantogotoI never understood his desire of putting an electric motor in a vehicle he was planning on using for road trips. Why would you want to stop constantly for 15 to 30min on a road trip?
Hopefully that burnt resistor wasn't part of the "balancing" circuit between the modules Seems like they would have some way to balance between them all, otherwise the balance issue will come back I wonder if a simple radiator assembly with a blower and a custom built shroud would allow "heating" for charging in order to prevent charging while freezing ah well...tons of work! Keep em coming!!!!
A123 Systems also made the battery pack for the Chevy Spark EV in the first iteration, which gave that tiny car almost 400 lb/ft of torque! Unfortunately they went bankrupt.
The chinese bought them, leading to more advance LFP technology in china then anywhere else. Part of the reasons why they were able to advance so quickly in EV tech.
@@markm0000 When I was researching which used EV to buy, I seriously considered the Spark EV (briefly) but ended up getting the Kia Soul EV. It was in my price range, excellent condition and built very well. Best car I have ever owned.
One of my neighbors has one of these trucks, and this has been very interesting to learn about. I'm intrigued enough that I may actually stop at his house and ask about his range and learn more from this person about the system and what they think about it. I had seen the badges on the rig and had figured it was a gm product not knowing it was a modified vehicle from a 3rd party.
Everyone keeps repeating this trope without any real knowledge- it’s pretty tiresome performative spamming. I’ve personally used & benefited from the platform. Might be good to double check and research your assumptions.

Oh no. Better help fly to you too😬. Guys, please don’t give your money to Better Help. They were already caught scamming the people trying to use their services a couple of years back, and they are back to do the same. They don’t even hire actual therapists because they don’t do background checks into the people they hire. They literally just hire anyone to be a therapist.
Therapist here. Within our community, we (unless in the process of moving or local group practices are filled up) stay away from BetterHelp, as they don't pay us jack crap. So those they do manage to recruit are, as OP mentioned, often not vetted.
If you want some good automated battery testers I use the EBC-A40L for single cell, EBC-A20 for ~0-18v cell or packs, and the EBC-B20H for ~9-88V packs but you need a power supply for charging with this model. I paired the EBC-B20H with a RD RD6018 power supply for charging. They all can be used without a PC but if you use a PC you can do more automation tasks and have graphs. The software can crash sometimes but the devices keep on going. I highly recommend them as they are cheap for what they do and they do it very well. I've manually balanced packs with these without issue but I also only use LiFePO4 and bottom balance and I dont use a BMS. You can also use them on other batteries like lead or if you keep an eye on them other lithium types or NiMh.
I remember seeing about these trucks in... Popular Mechanics? And I swear the battery pack for the van was BASICALLY under the two seats. And instead of the motor being where the transmission would have been, the drive motor was moved way back, and connected with a whole new drive shaft.
You have come a long way. From upgrading a Saab 96, repairing a Trabants’ Gearbox without falling into a pit, to this: understanding goofy electric vehicles better than the original builders and repairing them like a pro. In germany we say „Hut ab!“ to give credits for that.
Better help has a history of exploiting patients including selling their data. They have also been involved in large data breaches. Please don't use them.
I know it's a different hobby, but Aging Wheels doing DIY off-grid/hybrid charging would greatly benefit me. He has so many weird batteries lying around.
Hello, I am an electrical engineer with experience in battery pack and bms desing. If the cells all test the same capacity yet are unbalanced, that mean that the BMS is shot and it keeps discharging that cell uncontrollably. You should have used the van bms. Oh and great job! I love your content and your style. Please be safe and have fun!
As far as the cooling/heating system goes, I think it realistically ONLY needed heating and a rubber hose with the engine off high idle is going to provide enough for operation south of Canada and leaving it plugged in charging in a closed garage is likely enough to keep it warm: doesn't surprise me the exchanger system was deleted.

I am sure a few other VTrux owners could use those batteries over time since their is no equivalent replacement. My truck seems to be doing much better still getting 35-40 miles, but one day I will have to find how to refurbish my pack.
I've loved watching this channel over the years and watching Robert slowly and accidentally become the nation's premiere expert on weird old electric car batteries. Or at the very least, one of the only people who's willing to even touch them.
Very fascinating dive into their battery packs. I think at the time, not many people had a way to economically liquid cool batteries, thus the beefed up air cooling they did. I dunno. Also a valuable lesson in aftermarket companies and the lack of documentation and support- it sucks! I work at a Peterbilt dealer. Its owned by Paccar. So is Kenworth. Many Kenworths and Petes are the same underneath, just different skin. Yet some Kenworths we cant electrically diagnose bc we dont have all Kenworth wiring diagrams....we have to beg from a Kenworth dealer! Good luck to any Fisker Ocean owners.
Hey there! I am an engineer and I do engineering things. the label on that BCCM said Rev 1. This is a pretty good indicator that the object in question is a prototype, or pre-production part of some sort. In engineer speak, numericals usually indicate pre-production and alpha-numeric rev levels indicate post production launch levels of development.... just an interesting tidbit
I might look at getting 10x CC CV Output 0.5V-30V 4A Adjustable Power Supply Module @ $10 each and a 24v 500w Switching Power Supply for $20, totaling $120ish for 10 output adjustable Power Supply. You set a adjustable power supply with your (good multimeter), test open circuit voltage first for "CV" then set your multimeter to 10amp test and short-out the adjustable power supply thought your multimeter to read your "CC" setting
not sure about high capacity systems like this, but for run-of-the-mill batteries, never measure open circuit voltage. They need at least a slight load to get an accurate reading. Ideally, you measure the voltage while applying the load they're designed to drive, but a simple low wattage resistor (maybe 1/2 W) will usually do the trick. For example, I use a 39 ohm resistor for testing 1.5V cells, and a 330 ohm for 9V batteries. When the cells are good, the voltage dips a little. When they've seen better days, the voltage drops a lot, and usually drops by a millivolt or two per second.
Those are not lithium chemistries though. I'm sure LFP probably sag as well but they'll have a lot less equivalent series resistance than alkaline cells and therefore a lot less difference between load and open circuit voltage
0:35 no, nobody looks at this bubbly behemoth and thinks it's an older truck, that thing is rather new, not brand new but definitely rather modern. I'm honestly surprised it's not rusted yet.
Such a satisfying video to see the insides of such a unique vehicle. Sorry that it didn’t improve too much after reinstallation but but very enjoyable to see your process.
A useful solution to the heating of the batteries in cold climates is a coolant heater, something that goes inline with the coolant system and can warm things up so as to stop stuff freezing (typically used as a block heater to keep an engine warm, though other block heater types exist that heat the oil instead), feeding warmies into the pack to keep it happy, but, erm, would require that loop to be unlooped, because that's just silly... :P
Please get a better sponsor. Betterhelp is terrible. The amount of people I know who were matched with unsupportive therapists or even people with no qualifications is... unnerving. Completely unacceptable.
I have some shite multimeters and would impulse-buy whatever Robert recommended actually come to think of it I have paid for mental healthcare based on youtube recommendations - ADHD360 via "No Boilerplate". paid for an assessment but got derailed by the pre-assessment questionnaire so it's been on the back burner for... six months or so
I really do hope to see this channel grow a lot more since the content is so good. Lots of interesting technical content in an entertaining, well-edited setting.
Their a few reasons the peltiers could fail like that. My suspicion is they are clamped together with too much pressure and not enough give during temperature changes. Essentially differential expansion from temperature changes as they work stress the peltier and they eventually split through the middle.
I love these videos, not least because it's difficult to find a mechanically inclined car youtuber that both is so interested in EVs, but also able to explain things in such an understandable and entertaining way! Love your polestar btw, genuinely a dream car of mine. Being an owner of a Hyundai Kona EV, I'd love to see you tear down and check out a "proper" EV from a mainstream brand - a Kona, Bolt, or a Leaf and do something with them. Heck, the gen one Leaf, EV Spark, etc are all really cheap now, so maybe someday? 🤞 Hah, maybe you could take the good van modules and make an electric reliant! That'd be funny.
Very charming guy, great personality, and obviously super smart. I don't understand literally anything that's going on or what you are talking about but somehow I'm still riveted! Bravo!
When I charge LiFePO4 battery packs for solar, I charge the pack until the BMS cuts off. Then check the cells' voltage. If only a few are at >3.5V, I discharge them and then charge the pack again. If only a few are at
You might think Peltiers are more reliable because they don’t have moving parts but in practice they’re surprisingly hard to make reliable when you temperature cycle them often. They are prone to cracking as you’ve seen here.
I made a similar comment. If using those in a situation like this it's highly suggestible to buy high reliability / hardened quality modules from a trusted source
We are pretty excited for open sauce next week! And our Goddaughter is getting married near Nashville the bext Friday, so it's Lane Museum Time! Will be an interesting weekend a the cow palace. Looking forward to meeting some makers!
26:12 Passenger side headlight is out. Not sure if you all noticed at any point, so I thought I'd mention it just incase since it wasn't mentioned in the video.
Isn't it a good idea to get a LiPO/LiIon/LFP battery charger? Something like an ISDT Air8 can do 8s at a time and charge to any voltage you want. Such a device should be much more convenient than babysitting 6 bench power supplies. Heck, ISDT even make a 3000w charger that can balance up to 22s of LFP at the same time. That thing could probably balance this entire battery pack in a day or two.
They must've got a college grad to design that cooling system, because every electrical engineer worth their salt knows that the thermoelectric effect is rubbish for heat transfer efficiency unless the delta between the hot and cold side is massive (as in, hundreds of degrees massive). Evidently there was very little prototyping done before putting these vehicles into production, which is probably one of the reasons why they failed - a basic amount of focus group testing would've demonstrated the VTRUX is a product that not enough people want, especially at that price, to justify its existence.
Another commenter mentioned it..... But you REALLY NEED an automated battery testing/ Discharge/ charging/data logging device. bc-b20h are great for the price. The same brand offers many different models.

How do you balance (pun not intended) the workload of balancing the module itself as you’re also transferring energy out of it to a different module (this would be an issue when the cells within a module are mostly balanced, and bringing another module up would create an imbalance)? It gets pretty complicated in a hurry, so I don’t blame them for skipping that.
@@jacobcarlson4010 True, but then, at least, have a diagnostics/manual balancing connector available.
An un-balanced pack would still require a dealership visit, but significantly less work. All they would do is unscrew a waterproof cover, plug into a special charger, and let it balance for a few hours. Sure beats having to drop and disassemble an entire pack.
These are supposed to be fleet vehicles, so ease of maintenance needs to be a priority.
By like 26 minutes, Robert was Dunn with this project. 🤣
Am I the only one that noticed he has a lift in the ex bus bay now, which is awesome!!
It was only when I saw the lawnmower that I realised it was his workshop.
Although I will regret never getting to see that epic vision of a electric super school bus I am really glad he has more shop space to work with now. His other space was starting to look crowded.
@@ThemantogotoI never understood his desire of putting an electric motor in a vehicle he was planning on using for road trips. Why would you want to stop constantly for 15 to 30min on a road trip?
I thought it was another field trip at first, then I saw the plywood backdrop and riding mower. That definitely looks like the bus dungeon.
@@tspawn35 It was to have a Diesel range extender, it was going to be living space as well so it needed power for that stuff too.
Hopefully that burnt resistor wasn't part of the "balancing" circuit between the modules
Seems like they would have some way to balance between them all, otherwise the balance issue will come back
I wonder if a simple radiator assembly with a blower and a custom built shroud would allow "heating" for charging in order to prevent charging while freezing
ah well...tons of work!
Keep em coming!!!!
The shop looks totally different
We need a shop tour ASAP
I think it's the bus-bay.
Next video!
A123 Systems also made the battery pack for the Chevy Spark EV in the first iteration, which gave that tiny car almost 400 lb/ft of torque! Unfortunately they went bankrupt.
The chinese bought them, leading to more advance LFP technology in china then anywhere else. Part of the reasons why they were able to advance so quickly in EV tech.
I remember that Spark EV. It was so cool but entirely impractical.
@@markm0000 When I was researching which used EV to buy, I seriously considered the Spark EV (briefly) but ended up getting the Kia Soul EV. It was in my price range, excellent condition and built very well. Best car I have ever owned.
The screw removal/insertion montage sounded like some kind of industrial music. I'm diggin' it.
One of my neighbors has one of these trucks, and this has been very interesting to learn about. I'm intrigued enough that I may actually stop at his house and ask about his range and learn more from this person about the system and what they think about it. I had seen the badges on the rig and had figured it was a gm product not knowing it was a modified vehicle from a 3rd party.
I would put it all on black that he’s an electrical engineer and amateur mechanic to keep that truck working.
Hey you should do some research on better help. They are a very shady company and alot of their "therapist" aren't even licensed.
better help is kinda like the flu. every now and then it comes back
Everyone keeps repeating this trope without any real knowledge- it’s pretty tiresome performative spamming. I’ve personally used & benefited from the platform. Might be good to double check and research your assumptions.
@@adamdevereaux2459oh we have double checked. That's why we're here and so vocal. It's actually even worse than what I initially thought when researching some of the comments here that were absolutely true.
@@adamdevereaux2459 Having a good experience with them does not excuse the factual evidence of their malpractice.
@@adamdevereaux2459 They literally got slapped by the FTC for fraudulently selling confidential user medical data. It's not a trope, it's a real crime that they committed. Glad you got the help you needed, but they screwed many people over for financial gain and should not be trusted.
We apparently need an updated shop tour. That looks like what used to be the bus dungeon. You were even wearing a bus shirt. Also, what happened to Under Dunn? I miss seeing you build stuff. Not just tinkering on weird cars.
This channel never ceases to show us unusual cars......... that never became common for a reason.
I really like the battery charging fire containment tub
Oh no. Better help fly to you too😬. Guys, please don’t give your money to Better Help. They were already caught scamming the people trying to use their services a couple of years back, and they are back to do the same. They don’t even hire actual therapists because they don’t do background checks into the people they hire. They literally just hire anyone to be a therapist.
Always the same, thanks for the heads up
Seconded.
And they apparently sell your private information on for financial gain as well 🤷
Therapist here. Within our community, we (unless in the process of moving or local group practices are filled up) stay away from BetterHelp, as they don't pay us jack crap. So those they do manage to recruit are, as OP mentioned, often not vetted.
@@leotide1990 Yeah, but you can just check the license. I know my therapist is licensed, because I can look it up, took me all of 27 seconds.
If you want some good automated battery testers I use the EBC-A40L for single cell, EBC-A20 for ~0-18v cell or packs, and the EBC-B20H for ~9-88V packs but you need a power supply for charging with this model. I paired the EBC-B20H with a RD RD6018 power supply for charging. They all can be used without a PC but if you use a PC you can do more automation tasks and have graphs. The software can crash sometimes but the devices keep on going. I highly recommend them as they are cheap for what they do and they do it very well. I've manually balanced packs with these without issue but I also only use LiFePO4 and bottom balance and I dont use a BMS. You can also use them on other batteries like lead or if you keep an eye on them other lithium types or NiMh.
One of the best channels on youtube and I'm not even a car guy! Love your videos brother, never change! Humor is always on point!
I remember seeing about these trucks in... Popular Mechanics? And I swear the battery pack for the van was BASICALLY under the two seats. And instead of the motor being where the transmission would have been, the drive motor was moved way back, and connected with a whole new drive shaft.
Makes sense, in most instances work vans are 2WD, where the truck is 4x4 requiring a transfer case and driveshafts front to back.
You have come a long way. From upgrading a Saab 96, repairing a Trabants’ Gearbox without falling into a pit, to this: understanding goofy electric vehicles better than the original builders and repairing them like a pro. In germany we say „Hut ab!“ to give credits for that.
Better help has a history of exploiting patients including selling their data. They have also been involved in large data breaches. Please don't use them.

I know it's a different hobby, but Aging Wheels doing DIY off-grid/hybrid charging would greatly benefit me. He has so many weird batteries lying around.
Hello, I am an electrical engineer with experience in battery pack and bms desing. If the cells all test the same capacity yet are unbalanced, that mean that the BMS is shot and it keeps discharging that cell uncontrollably. You should have used the van bms. Oh and great job! I love your content and your style. Please be safe and have fun!
That is only true if ONE BMS is present, not multiple.
I appreciate your dedication to font changes.

BETTER HELP?!?!
ARE YOU MAD?!?
nice to see EEVBLog multimeter
Don’t turn it on, take it apart!
As far as the cooling/heating system goes, I think it realistically ONLY needed heating and a rubber hose with the engine off high idle is going to provide enough for operation south of Canada and leaving it plugged in charging in a closed garage is likely enough to keep it warm: doesn't surprise me the exchanger system was deleted.
Please drop better help as a sponsor, they are a scam
Why?
They are a scam because ppl are suckers.
I paid for counseling for my gf when she was having a hard time adjusting after college.
She kept claiming I wouldn’t listen and told me to get a counselor for myself.
I did….
He was like idk bro you’re a great listener and empath. You shouldn’t be having problems like that.
Let’s set up a double counselor meeting to get to bottom of it.
My gf’s female counselor said NO! That would make HER uncomfortable.
Despite me, my counselor
And my GF all trying to set it up.
My gf then went into a downward spiral and cheated on me and screwed me over everything and my counselor said sorry bro you’re a nice guy idk why the other counselor refused she sounds like the problem. 😢
Ruined a 7yr relationship.
keep em as a sponsor, let em give him their money, we all know its a scam and wont use em. everyone wins, betterhelp loses.
Yeah they are horrible. They match LGBTQ people with conversion therapist, even if you select your looking for an LGBT therapist.
I understood very little of this video, but as perusal, it was a brilliant video to watch and highly entertaining. Well done
I am sure a few other VTrux owners could use those batteries over time since their is no equivalent replacement. My truck seems to be doing much better still getting 35-40 miles, but one day I will have to find how to refurbish my pack.
Or just turn it back into a regular chevy
I've loved watching this channel over the years and watching Robert slowly and accidentally become the nation's premiere expert on weird old electric car batteries. Or at the very least, one of the only people who's willing to even touch them.
Thank you Robert for uploading this! Was having a crappy Sunday but your upload cheered me up
@19:15 TECHNOLOGY CONNECTION HAS WORDS FOR YOU.
Love the EEVBlog meter!
I like watching Robert get excited, whenever he opens up or learns something new
I don't need Better Help, I just need you to upload content as often as possible. It always makes me happy!
I appreciate the different fonts each time Peltier was shown
Just after watching the new video, I noticed that this isn't the old workshop.
Yeah after seeing that it’s obvious I’m oblivious
Very fascinating dive into their battery packs. I think at the time, not many people had a way to economically liquid cool batteries, thus the beefed up air cooling they did. I dunno. Also a valuable lesson in aftermarket companies and the lack of documentation and support- it sucks! I work at a Peterbilt dealer. Its owned by Paccar. So is Kenworth. Many Kenworths and Petes are the same underneath, just different skin. Yet some Kenworths we cant electrically diagnose bc we dont have all Kenworth wiring diagrams....we have to beg from a Kenworth dealer! Good luck to any Fisker Ocean owners.
The tool montages are so fantastic.
Thank you for helping someone who needed the help.
AW: A much more accurate meter.
Marco reps: Thrashes in his bed and goes to make sure there wasn’t a temp spike near his Keithleys.
Hey there! I am an engineer and I do engineering things. the label on that BCCM said Rev 1. This is a pretty good indicator that the object in question is a prototype, or pre-production part of some sort. In engineer speak, numericals usually indicate pre-production and alpha-numeric rev levels indicate post production launch levels of development.... just an interesting tidbit
Well.. I see batteries that are going in the Wego lol
I might look at getting 10x CC CV Output 0.5V-30V 4A Adjustable Power Supply Module @ $10 each and a 24v 500w Switching Power Supply for $20, totaling $120ish for 10 output adjustable Power Supply. You set a adjustable power supply with your (good multimeter), test open circuit voltage first for "CV" then set your multimeter to 10amp test and short-out the adjustable power supply thought your multimeter to read your "CC" setting
Glad I'm not the only one that reacts like that around spiders 😂
Not gonna lie, for a moment I thought he got electrocuted. 😂
not sure about high capacity systems like this, but for run-of-the-mill batteries, never measure open circuit voltage. They need at least a slight load to get an accurate reading. Ideally, you measure the voltage while applying the load they're designed to drive, but a simple low wattage resistor (maybe 1/2 W) will usually do the trick. For example, I use a 39 ohm resistor for testing 1.5V cells, and a 330 ohm for 9V batteries. When the cells are good, the voltage dips a little. When they've seen better days, the voltage drops a lot, and usually drops by a millivolt or two per second.
Those are not lithium chemistries though. I'm sure LFP probably sag as well but they'll have a lot less equivalent series resistance than alkaline cells and therefore a lot less difference between load and open circuit voltage
Your channel is a hidden gem, glad I stumbled upon it!
0:35 no, nobody looks at this bubbly behemoth and thinks it's an older truck, that thing is rather new, not brand new but definitely rather modern. I'm honestly surprised it's not rusted yet.
Better help is a big scam dont advertise it

Such a satisfying video to see the insides of such a unique vehicle. Sorry that it didn’t improve too much after reinstallation but but very enjoyable to see your process.
Peltier? That's where the 800W of absorption at idle were!
Except the truck DIDN'T have them, only the van pack did.
A useful solution to the heating of the batteries in cold climates is a coolant heater, something that goes inline with the coolant system and can warm things up so as to stop stuff freezing (typically used as a block heater to keep an engine warm, though other block heater types exist that heat the oil instead), feeding warmies into the pack to keep it happy, but, erm, would require that loop to be unlooped, because that's just silly... :P
But there is nothing to unloop that loop into.
Please get a better sponsor. Betterhelp is terrible. The amount of people I know who were matched with unsupportive therapists or even people with no qualifications is... unnerving. Completely unacceptable.
like, 17:10, can you get sponsored by a multimeter manufacturer
I have some shite multimeters and would impulse-buy whatever Robert recommended
actually come to think of it I have paid for mental healthcare based on youtube recommendations - ADHD360 via "No Boilerplate". paid for an assessment but got derailed by the pre-assessment questionnaire so it's been on the back burner for... six months or so

Better help is a total rip off,, Id find a new sponser,,, maybe Rayo Vac, or everready batteries

Their a few reasons the peltiers could fail like that. My suspicion is they are clamped together with too much pressure and not enough give during temperature changes. Essentially differential expansion from temperature changes as they work stress the peltier and they eventually split through the middle.
Uneven clamping pressure is a very quick way to break them i.e. non-flat or non-parallel surfaces.

I love these videos, not least because it's difficult to find a mechanically inclined car youtuber that both is so interested in EVs, but also able to explain things in such an understandable and entertaining way! Love your polestar btw, genuinely a dream car of mine. Being an owner of a Hyundai Kona EV, I'd love to see you tear down and check out a "proper" EV from a mainstream brand - a Kona, Bolt, or a Leaf and do something with them. Heck, the gen one Leaf, EV Spark, etc are all really cheap now, so maybe someday? 🤞 Hah, maybe you could take the good van modules and make an electric reliant! That'd be funny.
BetterHelp is a fucking scam! Don't EVER sponsor them again!
Very charming guy, great personality, and obviously super smart. I don't understand literally anything that's going on or what you are talking about but somehow I'm still riveted! Bravo!
He did make video in new shed ... before showing us new shed
When I charge LiFePO4 battery packs for solar, I charge the pack until the BMS cuts off. Then check the cells' voltage. If only a few are at >3.5V, I discharge them and then charge the pack again. If only a few are at
The factory replaced the cells without setting the voltages correctly? What a bunch of hacks
You might think Peltiers are more reliable because they don’t have moving parts but in practice they’re surprisingly hard to make reliable when you temperature cycle them often. They are prone to cracking as you’ve seen here.
I made a similar comment. If using those in a situation like this it's highly suggestible to buy high reliability / hardened quality modules from a trusted source

maybe the real range improvement was the friends we made along the way
26:12 Passenger side headlight is out. Not sure if you all noticed at any point, so I thought I'd mention it just incase since it wasn't mentioned in the video.
Isn't it a good idea to get a LiPO/LiIon/LFP battery charger? Something like an ISDT Air8 can do 8s at a time and charge to any voltage you want. Such a device should be much more convenient than babysitting 6 bench power supplies. Heck, ISDT even make a 3000w charger that can balance up to 22s of LFP at the same time. That thing could probably balance this entire battery pack in a day or two.
bc-b20h or something similar from the same company. Can automate things and it's kinda affordable
Thanks for bringing these repairs to TH-cam! Very interesting!
They must've got a college grad to design that cooling system, because every electrical engineer worth their salt knows that the thermoelectric effect is rubbish for heat transfer efficiency unless the delta between the hot and cold side is massive (as in, hundreds of degrees massive). Evidently there was very little prototyping done before putting these vehicles into production, which is probably one of the reasons why they failed - a basic amount of focus group testing would've demonstrated the VTRUX is a product that not enough people want, especially at that price, to justify its existence.
Another commenter mentioned it..... But you REALLY NEED an automated battery testing/ Discharge/ charging/data logging device. bc-b20h are great for the price. The same brand offers many different models.
