Very interesting results! I did my test 4 times (twice with an a/c and twice with a heater) and got results all within about 100wh -- all low 70% range. I didn't test before the firmware update and they had me on some beta for the ARM. Bluetti is sending a new battery and I'll do a before and after firmware update test this time. We'll find the truth!
Thank you. I'm looking forward to the results.
Working together to solve the issues that arise with new products to store electrical energy for use at later times and as one of the key parts of an off the grid system. Thanks guys, because of these efforts I'm able to live comfortably off the grid and I don't need to buy ice to keep my milk below 40°F and that makes me smile from ear to ear.
I wish every industry had people like you two who are in it to serve the public instead of just making sales. Thank you both for you efforts.
I couldn’t let the one test dissuade me from buying the AC300 combo anyway. 😁
I’m sure that if necessary, Bluetti will make it right before or after the combo is shipped to me.
@@jonjohns8145 You do realize hobotech nearly always gives you disount codes that he makes money off of when you use don't you? 😂
I Love that Will&HoboTom tag team and show respect to each other💪🏼.
Great job Dynamic Duo💪🏼🙏🏼
Bluetti said on facebook that they are sending Tom a new unit. In their own testing, they are getting what you got. Good to know you got you got good results.
UPDATE- HOBOTECH RECEIVED A BROKEN (DURING SHIPPING) CELL IN HIS BATTERY- HIS UPDATE SHOWS 90%. Bluetti is halting their shipping to reinforce their unit so their logistic delivery team doesnt break it during the shipping process.
I love the fact that you guys all talk among yourselves. I follow a lot of you and love your content. DON"T STOP SHARING!
If Hobotech only has one battery, you should try the same test with only one battery. Maybe there's a hardware flaw that only shows up with one battery hooked up?
The issue with Tom's unit may lie in the firmware or the AC300 inverter, or the battery module. The number of battery packs won't hurt the efficiency
@@tysonmarcus9231 it actually does. If the batteries are connected in parallel, for the same load you reduce the current/C-rate for each battery. And the capacity depends on the C-Rate! Therefore the Capacity (for the same load) should be lower with only one battery.
@@steffen12 good point. Or does it deplete one battery first then move to the other?
@@slayer66thfc In an articel about the system they said the batteries are connected in parallel. On a system level this would be the best, bc. the inververter always works in the same voltage level. If they were connected in Series the AC-DC would need to handle variable voltages. And for you mentioned type, they would need some kind of additional control mechanism (HW+SW). So i guess parallel it is.
@@steffen12 can you share the article?
I just got mine. I’m very happy with this platform and excited about the possibilities with it.
Hobotech’s unit was made on a Friday, yours was probably a Monday . 🤔
This is actually a valid point. I worked in the original IBM PC factory from 81 to 87, and despite being made in places like Malaysia and Indonesia, chips with a date code around a US holiday were much more likely to fail. Turns out they had US citizens as managers and QC, and they would go on vacation for Christmas and the 4th of July, etc.
@@john_in_phoenix Was wondering why and how that could be ? Until you said the part about US QC folks & managers . Nice input ... Gubs
LOL!!!
Will, my friend I have been watching your videos for a while now and have found them very informative. For the life of me I can't see you homeless or without support from your family or friends? I see you as a very intelligent person and very educated in your field. I would have taken you in just for your good soul? For what ever reason I am not here to judge just wanted to comment that I believe in you and I know you do too.
As a side note : Steve Harvey lived out of his car for 3 years!!!!!!!!!!!!!!!!!!!!!
Keep up the faith you are an inspiration to all who have fallen on hard times and come out winners..........................
love.... love ............ love your videos
What unit you Like more , the Titian or the blueitti ac300 ?
Yourself and Tom ? Only solar blokes I follow on here 👊💥👊
Hobotech got one bad blueetti, just like you got one bad big battery. This stuff happens once in a while it just happened to you With big battery and hobotech with Bluetti. you guys have massive influence so please be careful. Thank you guys for your videos keep them coming very informative. Will still massively proud of you Mr Smith.
Do a test with two ac300's utilizing the fusion box. And see how it performs at 240v loads.
Bluetti Shipping Dept. : .. We're sending this gear to Will Prowse, better make sure it's the best gear we have. Send that low grade gear to that Hobo Guy.
Lmao!
One thing we are missing is Will pulling the Solar Battery System (not a generator) apart. I would guess the systems that make it simple take a bit of power to run along with the typical inefficiencies of standard components.
the test should be as similar as possible... and you did mention you never updated the firmware and hobotech did. Could possibly be a software issue. Pls do one more test as similar to hobotech's as possible pls! Thanks and appreciate you, Will!
I trust what you say because you are doing it right and not just tryng to sell us junk like many people.
So glad your results were much better.
I did buy them.
Now I need your input on what solar panels to use here in Pahrump Nevada.
Thank you guys
If it's 87%, I'm bying it !!!
I just have to wait that Bluetti ships the product in Belgium 🇧🇪 ...
America first 😀
Solarpowersupply Sells it in Belgium!
@@KokibatchiWey61.8 thanks I check ! Indeed, I need to start saving money right away ahah
Greetings from Australia. Thanks for posting. Regards Stephen
Hello S. Hutton, have you found any good systems here? I'm in Melbourne and am mildly interested in updating my AGM battery for when I go car camping with my CPAP. I am quite happy with what I have, just that it weighs about 20kg.
@@l214laus They will be selling these units in November, you can buy the previous model currently if you like.
Thanks zforce69, I will investigate. Can you recommend a seller here?
Double the price in Australia,
Source: Australian
Man im happy to hear that Bluetti is sending another to HT and that you got better results cuz ummm I already wasn't a fan of the weight and form factor personally.
The power efficiency is a turnoff. Other competitors are more efficient and have better designs.
like which brands?
Maybe you should try with just one battery. My theory is that with 2 batteries it might be splitting the load output between them and not having to cool the pack so much. Warm inverter might also generate some losses. I don't think that's enough to account for the almost 15% difference in your results but it should at least allow us to uncheck that hypothesis. Otherwise, it might be just a bad battery he got, I guess
Did you discharge the battery using a resistive load or inductive load? The variation in results could be because of change in Power Factor of your test and Hobotech's.
The power meter might give different results if the power factor is different and it might have measured the apparent power and not real power.
they both used resistive loads.
Now I'm really confused! I almost pulled the trigger until I saw the invertor efficiency. 85% and above is what I would have expected to see.
I have the same meter, and I have found it to be very accurate as well. Like you mentioned, retaining memory makes it more useful, and it is about $2 cheaper than the Kill-a-Watt that doesn't retain the memory. Maybe Tom has a battery with a bad cell? I don't know, but the results you got were very believable.
I'll have to pick one up. I like the memory and backlit screen. It's not always easy to see the unlit screens.
I've also seen various tests over the years showing the vast majority of those meters are indeed accurate.
Again this is a truly awesome amount of power.
I would recommend professional installs at this level something that only Tesla offers at the moment.
Still for an off the shelf product this is an amazing thing.
Long cooking oil
Strong buy
Try with one battery. I think Hobotech had that issue with a single battery
Takeaway: DON'T buy any of this stuff till it has been on the market for at least 6 months, regardless of introductory (aka beta testing) pricing....
Bluetti will have released 7 successors after 6 months :D
@@HolgerNestmann It's cool they are releasing such innovative products so quickly, but I think it's coming at a cost in testing/validation. Eventually, this will end up hitting their bottom line and their release cycles will need to lengthen.
@@NeverTakeNoShortcuts I agree, but the things keep flying off the shelves. I have an AC200P and it‘s ok‘ish. But it has a horrible soc meter and no firmware update/connectivity option. So I am really one of the people who are not well off. You see them fix these issues with upcoming products, so they mature new skus but not existing skus
I bit the bulletin so to speak. The 21% discount was hard to pass on. The AC200 Max testing showed good results, but sold out before I could order one. I am going this unit mainly for my van build. It’s portability and simplicity seem to be my best solution.
@@HolgerNestmann I bought a Ac200P too. As you say ok-ish. When you look at this crowdfunded model with fast release cycles, purchasers like us are funding their product development cost. Only we can decide if that's a good value for us. For some people, they have to have the latest bells and whistles, even if there are fundamental issues (like efficiency, for instance). I would just caution that the 20% discount shine wears off pretty quickly if the device has serious defects..
I just got my Bluetti AC200P on Aug. 31st. It is not reading wattage correctly amoung other things. Max Oak has just been giving me the run around. They keep having me make videos of the issues. Sometimes it will not show that there is any wattage being dispersed and when it does show wattage when I use more wattage it says that I am using less. I was very excited about getting one of these and when I seen that it was messed up I just thought " no big deal, they will just have to replace it."
WRONG!!! They are not being cool about this at all.
Great review. Please review the Pecron S1500 Solar Power Station. Thanks
I saw Toms comment earlier. You got lucky lucky battery units. Nice one. 😀👍
Recently found your channel and subscribed to better understand how to get the best bang per buck with solar. Hoping you'll run some fictional systems (high, medium, and low cost) that you'd put into a long distance sailboat. Chargers with bluetooth monitoring appear to be best since equipment needs to be stored in lockers devoted to dryness, and other such constraints like sail shadow will limit the amount of power available. I'm researching for a 30 foot (that's on the small end) retirement boat I hope to purchase and outfit in about a year from now. Best wishes!
I have yet to see one of your post that I don't like. Great work
You mentioned that he did a firmware update could that have something to do with the low 70% he got ? Would be interested to know if the other people that had also the same low results also updated the firmware??? 🙏🏻😊
Maybe if the (new?) firmware has a setting to specify the max charge and discharge percentage, so you can make the batteries last for more cycles?
@@fezdk Will actually showed that it does have this feature in his original video. For a capacity test it should be set from zero to 100%.
@@john_in_phoenix Hah, I thought I remembered that, but thought it might have been some other BMS video. So wondering if that might have been reset to more conservative values for the firmware upgrade that Hobotech did.
I had noticed the overhead with the ac200p was high even with the inverters off. I and other left the unit on with no inverters and it would drain pretty rapidly. If you drain the batteries faster the overhead of the unit is much less than if you drain them slower
I am making sure I understand the whole process before buying anything. I have a house that uses 22.5kwh/day. I want to create a Grid Tie system that runs off grid as much as possible. For batteries it looks like I need 10x 24v 100mah batteries. My house is in the midwest so assume 4 hours of sun a day and that means 6kwh of solar panels or 9x 360watt 24v. Totals about $4k for batteries and $4k for panels. I know there are more costs for hardware and I will hire help to wire it up to the grid and help with assembly, but I want some confirmation that I am on the right path. Thanks.
Hey Will, I don't know if you get much from the "likes" here on YT, but you have recently ended your videos so quickly that I can't add a like (w/o going back, restarting the clip, getting the ads again, and then liking). Please give (those of us on TV and Streaming devices) a few moments to "like" at the end of the video. Thanks!
😄I know what you mean but if you watch enough of Will's videos, you can hear it in his voice when he's winding down. I think he is watching elapsed time and has set himself a limit so he minimizes editing. Can't blame him at all.
Interesting!!!!...thank you Will 👍👍😎
So is it a buy or don’t buy?
Tests capacity results will vary depending on the load. Inverters efficiency has the best efficiency at a particular load.

Love to see a review of the Milwaukee MX FUEL CARRY-ON3600W/1800W POWER SUPPLY
Perhaps run another test using only one battery.
At 1st I was sure it was Hobotech, especially since he admitted he was in a mental fog from no sleep due to working on vlog 30 hrs b4 uploading. His 7am claim really screwed with my mind. But now that he said that he ran the test 4 times, logic dictates it had to be the updated firmware.
I ordered my bundle pkg. from Hobotech cuz he uploaded 3 hrs b4 (7am, haha) gave me time to soak in his video. I also love that he is more detailed in his reviews than Will. Although I am still waiting to get details on how precisely to use that 24V Cigarette lighter port. (But still, I came here to get Wills' take on it) These 2 guys compliment each other very well. I hope to get a 3rd AC300 with more B300s' soon.
I don't think the firmware is backwards compatible. So many possibilities of error and the only way is to re-run tests. It sucks but there's no other way. It can be firmware issues, firmware coding error, hardware and software link issues or just plain and simple faulty hardware and the list goes on.
Nice test. I ordered the AC300. 👍🏾👍🏾
Really interesting. Key thing this taught me again is the differentce between Will's raw batter tests where he's measuring at the battery vs. measuring on the AC side at the charger AC plug or the inverter AC plug. Really different looking results by measuring different places.
Also if you're being friendly with your battery and not going all the way to dead flat 0% you gotta chop that capacity off for your expectation. The review video shows you can set those numbers in the Bluetti which is a neat feature.
Tom used on battery and you used TWO, Maybe its the double battery test that gave you the different results????
Just a guess
Will, did you see that Renogy just announced a 100aH LiFePo4 at $400 less than a Battle Born? Did I miss something here? Thanks.
I saw Ampere Time 100ah 100amp BMS amazon for 379.99
Battle Born has had their batteries on sale for several months now. I picked up one of their 24V/50Ah units for $800 (usually $1100) in August. Yes, even on sale, they're pricey. But I like the 10 year warranty and the redundant cylindrical cell architecture. Will's tear-down video of the Battle Born 12V/100Ah unit convinced me that it was a good way to go.
Yah I was wondering where the round trip efficiency test was……. 😀
I'm curious to see what the market for these will be. Lots of capability and flexibility but for the price you could DIY a substantial solar array and get equivalent capacity storage.
WONDERFUL. You are NOT missing anything. As you know now, Hobotek received a battery with a bad cell. Thanks! Bye.
Good work Will. Thanks for verifying.
Jason over on the Jasonoid - Solar Power, Batteries, and More! channel got 85.2% efficiency on his ac capacity test. HOBOTECH updated the firmware prior to his test. Maybe that's the difference. It could be Bluetti's firmware still has some bugs.
Love how he said he's a little salty lol
Do a video on a solar system for travel trailers with lead rv batteries. Or tell us what you would use(components). Sorry not completely related.
Have you ever tried getting a calibrated watt meter? I worry that the off the shelf ones may be iffy. On the other hand, as long as all tests are done with the same meter, then at least it’s apples to apples, even if the final numbers may not be “accurate”. While they may have an accuracy of 0.1 watts, there is a huge difference between accuracy and precision.
A good thing to try would be test the same battery with each of your meters.
Generally,multimeters are “good enough “, especially with Fluke and similar name brands. But some low shelf plug in watt meter, that is not at all guaranteed.
I'm less reassured after these dueling tests from Will and Hobotech. Makes me think Bluetti is rushing their product launches without enough testing, and I could get the unlucky unit that underperforms from a bad batch.
can you use a ac300 or ac500 with a rack mount battery that is not a bluetti battery?
Hi. I really love your videos. You are very informative and helpful. Do you have a video reviewing the Duracell Power Source 1440w that Costco is selling? Duracell do not specify if the unit is Pure Sine Wave or Modify. Thank you very much and keep it up. 👍🏼
I wonder if they set the voltage disconnect higher to protect the lithium cells and make them last longer. So maybe theyre only discharging down to 20%? Seems logical to me
Last longer? It is lifepo4. The screen and buttons will fall apart before these cells do. I don't see the logic. If a company did that, don't buy their packs. That would be silly
@@WillProwse And this is why your the expert! :) I am just getting into Lithium for my solar setup, so this is pretty new to me.
Will, you forgot to mention the 24VDC output. HOBOTECH did in his review and he is correct they need to do something so people do not burn up their 12VDC goodies.
Yeah, I also caught that. The inclusion of a standard sized cigarette lighter port that ouputs 24V was an odd choice for Bluetti. I envision a lot of people who don't read manuals very carefully (or at all) will plug 12V devices into this port and fry them fairly quickly.
I bot 2 AC300s' and I DO NOT HAVE A CLUE what to do with a 24V cigarette lighter port !!! So now I will have 2 ports that I will be constantly looking at while swirling around my cell phone charger as I walk past them! I may need to seal them shut with Gorilla tape to prevent me from eventually plugging that hole with one of my many 12 V cords. Hey, it's a hole, it needs to be plugged up (hahaha)!
@@TexasLocalProduce I probably would super glue them so no one could ever use them.
@@rodneyross5282 Hahaha I paid for them, I prefer figuring out how to modify them to make them work for me.
Maybe the update is altering the numbers?
Hi will, keep up the great CZcams videos very interesting 🙂
Hello brother first of all wanna thank you for your work and the help and teachings you offer alot of information blessed to have you !
I have a quick question is it okay to exeed the voc with like 2 4 volts?
Thank you so much!
From north of Lebanon following you😊🙏
How does one calculate the charge and discharge efficiency? What is the formula/math? Thank You.
Thank you for the video. How it's about the fan? Is it noisy? At watt does ist start? I'm asking for use it inside my living-room. Thank you
Thank you Will for sharing. Love your approach.
retest it with single battery & hobotech should retest on 2 batteries like u did
I have a stupid question, you hear a lot of people say that they prefer a DIY setup over an all in one unit because if something goes wrong they can troubleshoot and replace things easy. But wouldn’t it be just as easy to take an all in one unit apart and do the same exact thing?
I assume disbalanced cells due bad factory matching or drifting from heavy load testing with to weak passive balancer as a cause of the not consistent results.
Will, you pulled at a much higher rate that HOBO which means your test ran for a much shorter period of time, making your results look better (less time for the inverter to run).
If you pull at 700-800 watts you may be able to reproduce HOBO's results.
No, I have twice the battery size. It's nearly the same c rate. And even at a 1C rate I would pull nearly the same. You should check out my beginner videos
@@WillProwse The video showed you pulling about 2740 watts. HOBO's video showed him pulling about 820 watts. HOBO did comment that he tested with a 1600watt heater, but the test he showed with the heater in the video was pulling 820watts and it took 161 minutes. It appears you pulled at a higher C Rate.
I just discovered your channel about a week ago, I will go back and look at your beginner videos because that is my level =)
@@scottzettervall429 no, I pulled 1200 watts for my capacity test. I pulled that large amount just to get it to zero. I would never pull that rate for a capacity test
@@WillProwse ah got it, thank you.
Try discharging the last 5% battery at a lower rate so the battery disconect dosent trip early
I wish I could get this in 🇨🇦
Try updating the firmware in your unit and see what you get. Maybe a glitch in the update??
Question not directly related to video.
When battery reaches 80% due to cycle life. How long will it maintain that capacity?
pulling the energy out fast with heaters or ac units generates greater losses I guess
Really like these shorter videos!
Thank you for reporting.
Hi Will, thanks for all the useful and helpful videos. I want to buy your book, but as it is from 2017, do you think it is still “valid”? This, as the inventions and progressions are very rapid in the solar industry (e.g. LFP etc). Will you have a new edition? Thanks!
Perfect
Maybe in the firmware update it changes the depth of discharge and charge max/min settings?
How about doing the test with just one battery instead of two?
So a Bluetti AC300 and one B300 battery will make my wattage over 6,000 ?? They both get charged up together and both operate my equipment together? Are they both Lithium IRON Phosphate?
Hey Will! I'm looking to build a system and I want to buy your book for research and reference. I noticed it was published in 2017; Have there been any big changes or updates to Off-Grid solar systems that I should be aware of that won't be covered in your book? Do you have any buyer's guides for system components, or is that mainly covered in your videos? Thanks for making solar energy so approachable!
Great video
Sorry Will, clearly your battery is defective. You were not supposed to pull 87%. Tom’s result are correct. Please send your battery back ;)
I guess any one unit has a chance of being defective.
Will achieved better results. he was puzzled by the poor result from Toms test
be interested to see what you find on an ANKER Power station 800 or the 400
I picked up an AC300 with 2 B300s for use with my travel trailer. I have encountered a problem though in that the 300s need to be indoors to keep them dry and climate controlled. I have an unused bunk bed to organize them but how to connect to that 30amp RV socket? I have the 30amp cord outside the trailer but I want to keep it for use with shore power when not using the AC300. Is there an elegant solution for adding a female 30amp socket to the trailer? All I am finding is how to add 30 amp male sockets to RV's and trailers.
QUESTION: Can dual Bluetti AC300 charge an ev using 240 volt through an EV Charging station?
Could you charge the ev while driving? assuming you can get the wire from inside the vehicle to the charging port.
What’s the most efficient way to charge the EcoflowRiver Pro from the AC200 Max
As someone just getting started. I live in the mountains of Colorado. I want to solar power a water heater and heat pump. How big of a system will I need? Is there a formula that can figure this out? Is there a video of sizing? Can you direct me to a one stop shopping place or should I expect to shop in multiple places?
Try the test with only one battery 🔋
I think that maybe his update changed it.
I am trying to pick a system that can back up my home during a power outage, and run my RV (microwave Air conditioner, and lights) in the high country of colorado (we boon dock) any best picks?
Quick question.
You said discharge was at .5. Is that correct? or did you mean .25? Or did I hear it wrong?
Oops .2C
So Will, which solar generator would you recommend the Delta Pro? ??
Did Tom fully discharge and recharge before testing like you did? Can that recalibrate the BMS to "know about" the full capacity?
With bluetti or eco systems .. are inverters critical still or skipable? Writing from central America where shipping costs are way high
