As an engineer, you've gained my respect. I've never seen a company provide a teardown video of their own product and expose it to the scrutiny of the world like this. From what I can see, it's a very well-built, very genuine device. I won't buy one because I've already spent all my money buying standalone inverters, battery cells and chargers to perform the same function, but if this existed back when I started building out my system I think I'd have definitely looked into buying this instead. You've done a really good job!
Cheers! There's another teardown video coming soon. I promise it is not gonna let you down either, subscribe to stay in the loop😎
You took the words out of my mouth
EcoFlow are amazing
I’m in touch with them myself 😉
The future is EcoFlow
Love these. Any company who has the confidence to actually show you the build, is amazing. Love these disassemble videos and your torture test ones too. Keep up the amazing work
Thank you Clark!
@@EcoFlowTech
Thanks Tim for introducing me.
@@EcoFlowTech do you guys really help with the warranty?
@@GabrielV93
First hand I can say they do. And they help very quickly.
Things like this made me just buy one. Confidence to show you what’s inside gives me confidence in the product.
Thansk tons for yours watching and support Matt!!
I am certain this video has made many people buy this product as I did. The build is excellent and to show it is even better.
Thx tons for your watching and support!❤
@@EcoFlowTech and Ty for offering the best sol gens.
I have three power stations from EcoFlow. They have one thing most of them don't a killer guarantee and 1 hour charging.
@@nightstringers I didn't realize how fast it really was until the power went out this weekend and I used my River 2 for the thermostat, but had to charge it at a friend's house and it charged before any other USB-C battery even hit 50%!
Then while searching for a larger battery I couldn't believe other competitors were advertising 5+ hour charging speeds like it was a good thing! Ended up buying the Delta 2 because it was on sale for $650 and came with a nice $80 outdoor carrying case. What an incredible deal!
I love teardowns, and have I ever seen a company do a teardown of their own product?? Respect! Also: well built and indeed looking better than version 1. Love it. 💐
I am thrilled that you love our teardown video! 😊We are proud to show the inside of our products as the ever-upgrading tech is the key to valuable products.
Agreed! I've only seen this before with the Framework laptop and it's easily been the best computer I've purchased.
My EcoFlow River 2 came in so useful during the power outage this weekend that I decided to buy a Delta 2!
Great video of the Delta 2. I'm very happy that I can still use the extra battery from my Delta Max and connect it easily.
Good job breaking it down for us!! Just unboxed my Delta Pro, haven't even used it yet, but man, the piece of mind I have now!! Thanks again!
Great choice! im sure you gonna love it
Thank you thank you, my ecoflow ended up falling off of my work table and some of the plastic panels popped off so this was nice to see a reference to fix it and put it back together properly.
I am impressed with the ease of disassembly, and the quality of construction. I think it is awesome that a company will show you the inside of their product. I am very happy with my Delta Max, and my new Delta Pro!
So glad to hear that! Thanks for you support Tom!
Evolution. One of the meanings to life.
Good job guys!
It shouldn't take laws, you don't need E.S.G. scores or any other malarkey for companies to take notice that this is how you treat customers, This is an excellent example and I hope more companies follow your lead. Bravo.
Not going to post my rant here, but I hear ya. Liking their products, and community so far.
Thanks for this disassembly
That looks like a pretty solid build. Kudos to Ecoflow for making a 1024Wh power station and making it that portable and small.
Love my Delta 2 even more right now !
Lovely inside insight
Thanks for the teardown. Delta 2 is purchased, waiting for delivery.
thanks for your support!
I love my Delta 2. Quality product
Not long to wait before it's on the market... can't wait...
I purchased a Delta 2 in November 2023. I've already had a PSDR Board failure after very mild use. I'm hoping it is just an anomaly. If they promote the battery life for 10 years worth of use etc. why not offer a compelling warranty to back the product. One year warranty doesn't fill me confidence my Delta 2 is going to go the distance. the battery may be useable but means nothing if everything attached to is fails. Time will tell. I'm postponing other ecoflow purchases until they have had a bit more time in the market and see how others experiences compare.
They are getting lot of bad reviews on amazon, these youtubers are biased and i have purchased delta river 2 and will see how good it holds
amazing!!
Can’t wait to get mine!!!!! Thanks
It will be available for purchase in couple of days on 16th of October
/September/
you think we can replace the noisy fans for quit ones . . . just asking ;)
nice an upgrade to the batteries.
hopefully this would also be available in the Philippines
thank you for doing this. these are a big investment so it's always nice to know what's inside, how it's built, types of batteries used, etc.
there's a big difference between the cheap amazon no-name brands and quality ones, even if the numbers are the same.
Glad the video is helpful to you! Subscribe to our channel to learn more about the latest product info! ❤
Was looking to see what the fan situation was because after hearing the fan on my River 2 I figured for use in the house I'd want quieter fans from Noctua. I was not expecting to get a manufacturers tear down as a result! Hopefully their fan connector isn't odd and I can grab some off the shelf converters, but if I have to splice and solder, so be it. My Delta 2 arrives in two days, yay me! This was an excellent video, informative and to the point!
haha thanks for your nice words although we do not recommend our users to tear down the unit themselves lol
Seeing this power station get fully charged in 70 minutes is truly amazing. I do wonder what speed the next release will have.
Even the delta pro charges in under 2 hours, They really are the fastest charging units available. And the fact everything is internal, you don't need to keep track of a separate inverter, that is a big win as well
Fricken neat!
Excellent material, thank you! And when somebody says Delta 1 has a many cables and connectors, should disassembly for example Goal Zero Yeti series ;-). Ecoflow has a very clean design of the PCB's I like it! One weak point is cooling. R&D should focus on airflow techniques, bigger fans, less noisy, RPM modulation hould depends of real temperature on active elements.
Thx for your suggestions. Delta 2 fans RPM are working according to it's temperature
@@EcoFlowTech this is great information for all potential buyers!
Awesome thanks for this is amazing to see an official teardown, just one question though- is it actually safe to be opening and touching the internals or has the box been discharged?
I have just received mine. Is is normal that the left front fan(looking from screen side) blows a lot more air than the other 2?
i just got my delta 2 and i see that max solar input is 500 watts 60 volts 15 amps
what if my solar panel configuration ends up at lets say 600 watts 58 volts and 20 amps ?
will it hurt the delta 2 to have more amps and or more watts coming into it or will it just not use anymore but be fine. ?
👍 Thanks, I needed that. Sooooo, you just borrowed a friend's wood working shop and apron to film this in, or what?
Hi, can you advise what are the exact specs of Delta 2 fans? The fans are very noisy and I want to swap them with quiet Noctua fans. If you are able, please suggest the exact model of the quiet Noctua fan for replacement.
Excellent video, but it makes me want to know… where do I need to cut & solder to install a physical shutoff switch for the Bluetooth and Wi-Fi?
I expected the Delta 2 to have an extra battery but realizing now that I can increase it to more than 3kWh. I am a happy camper.
Fantastic video thanks! Would EcoFlow ever consider just sending out a front or back panel for replacement by the user? Just thinking about the shipping cost and inconvenience of something like a Delta Pro
nope. We'll get u covered by 5 year warranty and do all the work for u
Got a question what can I do with a delta 2 that won’t charge anymore? Left it plugged in believe battery overcharged?
the glue (better named silicone kit) is to keep parts from squealing when it's in use (coil whine)
Is it possible to replace the noisy fans with 25mm thick ones? Like the Noctua fans? It seems like they'd fit in there.
Do you have a how-to video on individual battery replacement for the Delta l? It contains 140 small batteries and I have one battery that is overheating and causing the unit to shutdown.
Can you upgrade the fans so they are not so loud?
SUPER!
Amazing
Thanks!Glad you like it🤩
Good to see that Ecoflow was able to pack in. kre than 1kWh in that small body.
Do you know how to hard reset it? My one just stopped working. I cannot power it on but after several hours if I press USB on button, display turns on but flickers for a 1-3 seconds. Sometimes it happens simply when I insert power cable.
What solution did you find? I can’t get mine to charge left it plugged in and that was it overchatged?
Can you put extra fan to help cool down the battery during too much heat?
Can you make a video to talk about the fuse inside delta 2 and how to replace them?
Thank you very much for this video. Can you please make a teardown video for the Delta 1? My unit is out of warranty and I need to service it. Seems like to separate the MPPT and Inverter boards, I have to desolder some wires coming from under the battery?
Hi Kris, can you specific the problem you come across?
On future version could you add a removeable grill over the fan ports with a fine mesh. I have had mine for 3 months and twice I have had to remove the cover to remove something caught in the fan which the software cause as enough of an issue too turn off the AC outlets. If there was a easily removable hard plastic mesh piece that could be washed off, dried and snapped back in place instead of popping up the trim ring, and then cover that would be awesome.
Hi there, thank you for your feedback, I have passed on your feedback to our product team. Cheers!
We have just order the DELTA 2 it is going to be a game changer for us in our van the main reason is the charge time omg we have got 400w of solar the build quality wow
When using solar panel, is it recommended to add extra safety devices like DC SPD or like when connected to Ecoflow powerstation?
Hi sorry for my late reply! Generally the PV charging surge protector is not a must-have as our generators have overcurrent overcharge protection. If you think it is necessary to install an RSD or fuse for safety, you can use a 23/24Amp. Please note that the PV input current should not surpass the maximum solar input the generator can take.
hello. I would like to know what kind of individual batteries it has. it was also good to put it side by side with a 12v lifepo battery used in motorhomes with separate inverter and mppt for those who already have all these last items installed many times at the factory in motorhomes, if even so it is worth changing and purchasing the ecoflow. I would also like to see stress tests on lifepo 12v batteries with inverter connected to microwaves, coffee machines ....
Hello, the battery DELTA 2 adopts is LiFePO4 battery chemistry which gives you 3000+ full charge and drain cycles and 6x longer than industry average.
Steep price tag but the build quality is spot on!
I'm curious what size those monster cells are
I have a Delta mini and need 15a (12v) during the start up of the heater for my van - is there any way to bridge the 12v car output and 2x 3a outputs?
There is no way to bridge. It is recommended that you use a DC to AC adapter to charge through AC.
Damn man, im interested in those blades on the wall behind this kidd!!! Any info?
Awesome to see how's the "grounding" done so I can show this to my house electrician. The reason is the terminology in US and in EU is a bit different and some old-style techs are speaking a different language, so explaining what's a floating ground etc. is a bit of a mess, showing him this video def. helped a lot
Cool! Glad the video is helpful to you!🥰.
@@EcoFlowTech I would kindly ask to make a video how to properly run your house in EU standards off a D2. There's a plenty of such videos regarding US-style power systems, but none - regarding EU. Currntly there's a 3 standard schemes here - with two cords (phase and neutral, which also serves as "ground"), with three cords (phase, neutral, ground), and a three phase system which can be in two variations - neutra, phase 1, phase 2, phase 3, and - neutral, phase 1, phase 2, phase 3 and a separate ground (which later connects to neutral at station or at billing counters). A lot of people are seeking on a way how they can power home appliances here, including lighting in apartment in residental areas, and some are starting to make mistakes connecting their D2 to wall outlets - seeing some videos with a simple automat system with two cords and trying to replicate this on three phase system without any knowledge on how unsafe it is. It would be awesome if Ecoflow would record a standard safety video with do's and dont's regarding 220v standard systems
like - what kind of cords you should use to power a home off a D2 (their size, wiring scheme - grounded or not etc), how to make a power split system when one can switch from a D2 and back to wall power etc etc etc
Could you read off the PD controller IC's for the 100W PD ports next time you do one of these?
Yep, sure!
Thanks for the review of the Delta 2. All I can say is that I am impressed by it, especially the faster charging that it has.
Hello
Can we replace the battery after all cycles done it means after many years when the battery died, how many volts is the battery if we replace it ? Thank you plz if you make a DIY video to replace the battery.
Hi you can exchange the battery if it is broken within the warranty. We do not suggest DIY replacing the battery.
How much battery cells are inside?
Anyways to turn off the Bluetooth feature?
What are the dimensions of the battery cells? lenght and diameter?
Love it, would love to use it together with solar for my apartment and balcony and ofc. Camping 🏕️
Do you know the voltage of the internal battery pack for Delta I?
Hi for DELTA 1300, the voltage is around 50.4V.
Can anyone tell me more about those Cells?
As i can see, there is a 4S 4P battery configuration over there, that means 16 Raw Cells.
If the Delta 2 has 1024wh Capacity Every Cell should have 1024/16 = 64Wh
Because those are Lifepo4 Cells that means the Voltage is 3.2V so, 64Wh/3.2V=20Ah,
Does those Cells looks like a 20Ah ???
I'm really interesting to know what batteries are those.
Should a number like 36900 sounds right ?
Does it void the warranty if we open the Delta2? Replacing the 40mm fans with Noctua fans for noise reduction looks doable.
did you try yet?
I made the mistake of trying to charge my delta 2 unit with 1200 watt gas generator without checking the htz output first. The screen showed the numbers jumping all around in value as far as watts input, then after a while the unit started clicking, then shut off. I tried turning on the ac ports, but they go out after a few seconds. What did i blow? The fuse? If so, can it be fixed?
Hi there, could you try shut down the unit, place it there for a while and re-turn on it. Please also contact our support team👉support@ecoflow.com with a video and your unit's serial number.
I’m impressed at those huge improvements on the battery cells wonder what chemistry bd voltage they carry now it look like huge capacity?
The battery pack voltage is 51.2V (single battery cell is 3.2V)🤗
@@EcoFlowTech that’s awesome they look so cool cylindrical all in one pack and powers a lot of stuff
@@EcoFlowTech I had one questions in regards to over voltage protection when a storm or lightning hits solar will or could solar panel induce a heavy high voltage that could damage the eco flow mppt circuits ? Is this unit cover against those types of events the delta 2 and others how much warranty is available included from you guys if I purchased from Amazon ?
Help help help I got this unit powers on then shuts off immediately. Company says im not on warranty?
Hi, could you pls tell me your order/case number? I will look into it.
What are the risks of delta 2 catching on fire. And also is it true you can charge the delta 2 to 100% to 0% over and over every day or do you have to put limits on charging and discharging.
Hi, take it easy, the Delta 2 has multiple protections such as over-voltage, over-current, overload, etc. so that the risk of fire is very low under normal usage. I suggest to charge and discharge between 20% and 80%, which is good for the life cycles of the battery.
Could the delta 2 charge a battery or batteries that are not the same brand?
Hi there, if you use a 120V AC charging cable to charge the other battery, it is fine. However we do not recommend charging via self wiring.
what size are the fans
Ecoflow did find a way to make the Delta 2 charge faster than the previous Delta and that is ashtonishing.
what are the dimensions for battery pack for EcoFlow delta
Hi there, sorry for late replay, it is around 525*267*376mm.
The XT60 connectors on our Delta 2 burned out and melted with only two 100 watt solar panels connected to it. And so I'm a little hesitant to just replace them and have the new connectors burn out and melt.
Do you have any suggestions or any ideas about this?
Thanks,
Mike
Hi Mike! Sorry about that. It is likely that the solar charging cable is short-circuited or because of the loose connection with Delta 2. Would you mind contacting our after-sales team for a new cable via this email: support@ecoflow.com. Next time, you can observe whether the XT60 interface gets hot in use. Hope this helps!
@EcoFlowTech
Thanks. I've also ordered a second Delta 2,, even though with our first one we charge it in town from the grid. We (a friend and I) have been off-grid for over ten years. The Lifepo4 batteries in the Delta 2 are excellent and we currently use it to boost out refrigerator and our freezer in the evenings when we get home.
Our cable with the XT60 connector (solar type) may have been faulty, and I'm looking to replace the onboard XT60 connector as well..
I'm assuming that support can tell me the specifics on that, also.
Thanks for your timely reply.
- Mike
I have the delta 1 (1300). Wish I could just swap out the battery for the new chemistry.
Ordered one with solar panels just incase another texas storm happens and we lose power I have the gas generator 4x4 xj fire wood and propane ect this just something I can use anytime
Smart choice!
Trying to figure out why you would use a woodworking set for video featuring plastic and electronics.
official answer: Because Delta 2 is great for powering a whole woodworking shop with saws and polishing machines etc. Real answer: we wanted to make video public soon and it was real close and convenient option. Please forgive my honesty.😅
He would have worn an eyeglass camera something like ordro ep5 so when he is looking down to drill we can see from his own perspective
wow that sounds pretty awesome, probably give it a try next time🤔
How about a delta 2 battery tear down / hack to add something that can be used as as a stand alone, say USB slots with an on off switch, where we can attached lights or charge items? - these things are just bricks otherwise, it would be great to have usb slots available.
I have a strange behavior of Ecoflow Delta 2 1024w power station. It is connected to the gas boiler and shows about 120 watts load. When the battery is charged it shows that it will work 8 hours on that load. After 4 hours of work, it shows that it charged 50%, but after that, it starts discharging very quickly and after about 10 minutes it shows 0%.
So my boiler can work about 4-5 hours on this power station, instead of 8 hours. What can be the issue?
Hey Ihor! Please operate according to the below: connect the network to upgrade the firmware. And then calibrate the SOC 2-3 times (set charge and discharge 0%-100% in the app, discharge the power to auto shutdown and then charge the power to 100% without input. This is 1 time for the calibration of SOC). And it would be better if you could provide the SN of your product so that we can track the product problems nd offer more solutions.
@@EcoFlowTech Hi, I updated the firmware and made the charge/discharge procedure, it looks like it works better. It is hard to do it properly 3 times because EcoFlow powers the gas boiler and light in the class of kids academy in Ukraine. We have electricity outages almost every 4 hours, because of the russian attacks. So EcoFlow Delta 2 is very helpful in that situation. Thanks for your support!
with all the complaints about the fan noise, I assumed that they would be impossible to replace.. clearly not the case! I don't see any reason why the fans couldn't be replaced with quieter ones if that becomes a big issue. Has anyone done a fan swap on their Delta Max?
Hi there! It is not recommended to dismantle the unit or replace the internal parts. You can try to upgrade your firmware to the latest version V1.6.2.52.
1:50 isnt that the inverter board on top? Edit: Nope they put everything on that top board. Impressive
Was expecting to see 32700/32650 LFP cells on the Delta 2. Now I gotta search and see what those cells are...kinda remind me of the 66160 LTO cells that Yin Long make.
i think 46160 but those are 25 to 30 amps.. maybe they oversized the battery or used less cells 14 or 15 for pack nominal voltage 50.4 i think
I think Ecoflow has anothet winner here. Definitely beats out all the rest.
3000 charge cycles is a lot. Which translates to about 10 years of use before going down to 80%.
Did somebody know the dimension of the lifepo4 cells ?
It's not 32700 and it seems too wide to be 38120 or 38140 🤔.
It is 40135!
How many life cycles on the Delta mini? Can we replace the batteries? Thank you
its 800 cycles, but battery pack is not replaceable
Thank you.
The Delta 2 came out immediately after I bought the mini. 🙃 And the mini was a huge purchase for me. 🔋 So wish ... 🕰 💨 I’m reading even if I don’t use it often it’s only about three years life for the battery? I tried my best to study. 😜
@@phoenixjordan7784 i bought my delta 2 and one month later they discount it 200 euros .. bad thing is one week after purchase it the first ever video of delta max2 apeared. wish i waited a bit longer .. so much double capabilities
are those 46160 ? ? i think yeap
Thank you for nice tear down video i will never ever buy ecoflow product mine has issue and still in warranty but they refuse to take any responsibility.
I just have to say . This guy doing the video is nice on the eyes . Thanks for the video my friend I have 3 different Ecoflow devices . Love them. 1 hour charging time is a game changer .
Cool, thanks!😎
I am getting ready to go vanlife full time and need to know what is better for the price ecoflow or jackery and don't wanna waste my money
ua-cam.com/video/_GhSIhtg3HE/v-deo.html
will it blend ?
blend what? sorry didn't get your question
@@EcoFlowTech ua-cam.com/users/willitblend
😅😅😅
cool
My Delta max isn't very old, it won't charge passed 70%, can it be returned to 99%? It happened suddenly, it was charging to 99%, and then overnight stopped at 70% and won't go back up.
Hi, could you pls check if you connect to EPS or use solar charging at night? And below is my advice:
1. Update your firmware, and you can tell me the SN number of your device.
2. Set the charging limit at 100% at EcoFlow APP.
3. Make sure the AC cable is well connected to the wall outlet.
4. Discharge the device to 10%.
5. If still can not work, you can record a video and DM us on FB, so that we can diagnose the problem better😎. Here is the link: facebook.com/ecoflowtech/
@@EcoFlowTech my Unit has returned to normal operation, thanks for the help.
just ordered a DELTA 2 today
Tell me more after you test it!😁
Are those 4860 cells?
Hi there, I am afraid they are not.
Mine is on its last leg and I've only had it 18 months. 😢
Hi sorry about that. Would you mind telling me your case/order number? I will prioritize it.
Impressive
How does a kilowatt battery compare to a amp hour battery?
1kWh at 12v would be about 83ah. Delta 2 battery pack voltage platform is 48v so it's around 20ah. That's not how we measure it usually, but i hope it answers your question
Ah is a value dependent on the nominal cell voltage. P = U x I
This translates into Wh = V x Ah
