Hi @VSM, thank you for getting ni touch with us.
The charging and discharging processes of the Premium 100 V2 power station are affected by many factors.
The discharge speed slows down when the SOC (State of Charge) is in the last 55%, and we consider this a normal phenomenon. During discharge, the internal battery gradually heats up, and the BMS (Battery Management System) will control the discharge speed at this time.
Additionally, SOC is a system-estimated value; it will be calibrated when it reaches 0% and 100%, and the capacity is not uniform across all intervals in between.
Upgrading the BMS can indeed optimize battery performance. However, we have found that your firmware is already the latest version, so we cannot push a new firmware update to you.
This is not normal when the first 45% discharges TWICE as fast as the last 55%.
I own another two Bluetti power stations (AC180P and AC200PL + B300K), none of them behaves like that under the same conditions, just as I mentioned above, nor during small loads under 100 watts, nor when having no load at all (just AC on).
It’s not normal to have 50% of useful capacity left, but showing 27% and recharging those 73% in 35 minutes in silent mode (SOC jumped from 87% to 100% instantly, literally in a second when I recharged it after the last post LOL)
Irrelevant. It went through 3 full cycles, as I mentioned above. At least do some edits to your stock answer.
Upgrading the BMS can indeed optimize battery performance. However, we have found that your firmware is already the latest version, so we cannot push a new firmware update to you.
- Powerful summary. It’s almost like I mentioned 3 times that I had the latest firmware + provided screenshots.
- I didn’t ask to help me with updating to the latest version; I can do it myself if there is one. The problem is, there is none.
Also, I like how you completely dodged the fact that it shows more output power than it should.
Send this topic to your R&D department and instruct them to conduct further testing, confirm all the points mentioned here, and begin working on the new firmware version. Beta will do if they can do it in a week or two.
And stop with these AI-like responses when your customer obviously knows what he’s talking about.
Btw, here’s the screenshot of HOBOTECH’s review of the Elite 100 unit (link with a timestamp https://youtu.be/K1cL36-x41U?si=tXUBF9evm-_hkiaW&t=362) where he left the inverter running for 12 hrs and it consumed 131Wh (he just multiplied it by 2 to give a 24hr estimate).
So it consumed 131Wh out of 1024Wh, but the SOC dropped to 74%
The firmware for this model sucks, and I’m not ashamed to be the first one on this planet to state the obvious. Get back to work.
Another timelapse from HOBOTECH for the reference. ELITE 30 v2 this time.
(https://youtu.be/0uLpAKfxXR0?si=fZuZnvVRQ5J4f7dK&t=339)
136Wh out of 288Wh in 12 hours. So roughly half of the capacity. And God almighty, the SOC is at 51% as it should.
Call these magicians/aliens, who worked on Elite 30, and ask them to do the same with Elite 100.
P.S. Actually 
, scratch that. I watched slow-mo and Elite 30 “consumed” 40% in the first 6hrs, so its firmware sucks as well. Call the guys who worked on AC180P/AC200PL.
Hi @VSM, The reason we’ve provided the same response is that for the same issue, there is only one correct answer — and these are based on verified facts.
Our previous replies were also made after thorough discussions with both the technical and R&D departments.
However, we’ve just released a new version of the BMS firmware, and I’ve already requested to have it pushed to your unit.
Please test it after upgrading tomorrow.
Successfully updated, but I’m in the midst of an outage for an indefinite period of time.
Testing might take a while, a couple of days maybe.
@BLUETTI_CARE Hi. I’m having similar issues with the Elite 30v2. My first one was replaced due to the issues as they were not solved by an update which Bluetti Support Squad kindly sent me when I explained the issue. The replacement was slightly better until an update a few days ago. Now it is a lot worse.
I bought the Elite30 mainly to run a 300w portable kettle. I run this kettle with no issues from the Handsfree1 and a 300w non-Bluetti unit, but I wanted a 600w battery so that it would not be running at max power during this task. Handsfree1 has 268wh and will boil the same amount of room temp water 10 times. The kettle has a fill mark and a temperature gauge. There will only be a couple of % variation in power used for each boil by Handsfree1 or the non-Bluetti battery.
Elite30 has 288wh. I would expect 11 boils of the kettle, it achieved that once, then got worse each time. Since the latest update I'm getting 8 boils of the kettle. The % used is all over the place. It will always run down fully from 100% to 0%, but it has periods of counting down extremely fast. So the % used to boil the kettle varies wildly from 7% to 30%.
It seems ok at very low or consistent loads, like running the same 7w or 100w lightbulb for hours, but apparently cannot cope with a 300w load repeated hours apart over a couple of days, even though it is rated at 600w.
I have spent as much time trying to recalibrate it as I have using it, it makes no difference at all. I also won an Elite 30 which displays the same behaviour. So that is 3 x Elite 30 that cannot cope with a load the Handsfree1 handles with no issues at all. I think that's too much to be a coincidence and would have to say, that unfortunately, I am very disappointed with my experience with this Bluetti product so far.
@BLUETTI_CARE
So I tested the “new” firmware, which was an ARM and DSP update (there was no new BMS version included).
Results are: Nothing. It changed nothing.
The SOC was at 56% after 24 hours of AC discharge, just as I mentioned in the original post. After 9 hours of discharge, SOC was at 80%.
The unit still has huge issues with small loads (40-120 Watts) and displays them incorrectly.
In the video above, I connected my double bed electric blanket (2x60watts), which is basically a resistive load, and switched between modes.
The unit still has no issues with heavier resistive loads, tho, like a 750W-1250W heater, as seen in the photos.
If this update is meant to be a placebo, it didn’t work because I tested it properly.
Back to the drawing board.
“Big fan” of the new Elite products so far. Looks like the only unit from the Elite series that works as advertised out of the box is 200 V2.
100 V2s and 30 V2s are a disaster. And I can speculate why there’s almost a radio silence about those issues: owners of the Elite series are mainly newcomers. Those who have a clue are still sitting on their AC180s and AC200Ls, as they should.
I am clinging onto my AC180 to dear life because every single compact/portable power station they have made past the AC180 has been ridden with bugs, or inverter compatibility issues. An example being my aircon/dehumidifier won’t run on newer Bluetti hardware but does perfectly fine on AC180 despite the other power stations meeting the specs “on paper”.
I feel like some Bluetti power stations are MVPs (minimum viable products) that get pushed out too early, then fixed in “post” by customer complaints, while the other (often higher priced) ones undergo more rigorous testing standards.
Hi @VSM, We have investigated this matter and found that the push of the new BMS firmware failed. Please do not worry—we have now applied to resend it.
Could you upgrade and test again tomorrow? We hope this helps.
Hi @Tezzabee, Thank you for sharing your feedback. I remember this issue—we previously pushed BMS v1087.06 to your Elite 30 V2, but it didn’t work. Is that correct?
It seems that after you received the new Elite 30 V2 and upgraded its firmware, the problem has worsened. Could you please let us know the SN code of your new unit and its current firmware version? We want to reproduce this issue. Do you think rolling back to the original firmware for you would help?
Additionally, we also plan to provide feedback on this matter to the technical department and quality department for discussion. We are confident that we will find a solution.
Hi @BLUETTI_CARE ,
Thank you for your reply, and remembering the issue.
I checked and both my Elite 30s have BMS 1087.05 following the most recent update.
I have recalibrated E30(1) again (possibly 5th or 6th time, I can’t even remember now). This is the replacement E30 for the one I bought.
I have run the same kettle-boiling task with the 300w mini kettle. There is an improvement, but I think this still needs refining to get the E30 to the same state of reliability and consistency of other small Bluetti units, like my Handsfree 1.
I got about 10.5 boils of the kettle on the latest attempt. There were 2 higher than normal % used out of the 10.5 times the kettle was boiled. Here is a list, C is degrees centigrade:
1. 90C (a.m.) / 12% used
2. 90C / 8 % used
3. 85C / 8% used
4. 85C / 8% used
5. 90C (a.m.) / 9% used
6. 90C / 9% used
7. 85C / 8% used
8. 85C / 8% used
9. 90C / 9% used
10. 90C (am) /15% used.
11. 90C / 4% used - only partial boil of about 30C as E30 ran out / shut down. If the BMS hadn’t sped up its countdown on boil no.10 it would likely have reached 11 full boils (unless it sped up on no.11 instead).
This is similar to what was achieved with the update you sent me for the original E30. Where it says ‘a.m.’ on the list this means it was the first boil of the day when the kettle was cold. I would expect a slightly higher % here (HF1 might add 1-2%), but this is again not consistent with the E30, as you can see from numbers 1, 5, 6 and 10 in the list.
Another issue is that in my experience there is no guarantee that the next time the E30 runs the kettle it will give the same results. And testing it is really becoming a bit tedious to be honest. The % jumps do not happen at the same point of SOC during different tests, although somewhere near the start and 20-30% seems common.
The results always add up to 100%, but the jumps do affect the capacity of the E30, eg number of kettle boils. I have watched what happens during the % jumps. The battery counts down the % remaining in full, but counts too fast. In my experience recalibration will not solve the issue.
It almost seems like the E30 does not have the full capacity of a 288wh battery, and has a very confused BMS that is trying to count down watt hours that actually aren’t there.
I will recalibrate my other E30 and similarly test it at the weekend. I estimate it will have pretty much the same results.
I hope Bluetti appreciate that what a customer wants is something that just works how it should as soon as you buy / receive it. I have quite a few Bluetti products and most of my experience has been unbox - charge up - update - recalibrate - enjoy. Having to deal with issues, multiple recalibrations, partially successful updates, further recalibrations and so on just to try to get the expected everyday use of a product is very frustrating 
You should include the temperature of the non-heated water in your column as a constant so the test results can reflect how much energy was required to heat up the water from WHAT to 85/90C. Where is your water source coming from? For example if you had a cooler morning or it got very cold the night before, the temperature of the water will be slightly less, so more energy required to heat up the water. For example, maybe in #1 the non-heated water was originally 18c but in the test at #5 it was 20c.
@Tezzabee If I were you, I would just get a $10 wattmeter and measure useful capacity for each firmware version with a resistive load, f.e, a 100W lightbulb or boil your 300W kettle 10 times in a row.
As for me, @BLUETTI_CARE , I haven’t received a BMS update yet. Will I get it tomorrow? Just want to make sure you pushed it before the weekend.
Thanks for your reply.
The water is kept at room temp in a bottle. Where it says a.m would be the coldest part of the morning, with the kettle also being cold. All the following boilings until the next a.m are during the same morning.
It’s not an exact scientific experiment. It’s how I use a battery to run the small kettle on a daily basis. I’ve been doing it for well over a year. I’ve used many different Bluettis and a River 2 for the same task over this time. I would expect some slight variations of a couple of %, but not the amount I have been getting from the Elite30. All the other batteries arrived and were recalibrated once, not the half a dozen times so far for the Elite30s. The AC output reading for the kettle stays consistent, but the the % SOC reading will just randomly run down much faster at times. The other batteries do not do this. They also do not have variations of more than a couple of %. I think that shows that Bluetti’s previous batteries work well and the readings they give are pretty accurate for estimating everyday use.
The E30 is supposed to be more efficient than the other, older batteries. It also has 288wh as opposed to 268wh, so it should give more run time / approx 1 more kettle boil. It doesn’t. With the other batteries the consistency is such that I can look at the SOC and know how many cups of tea / coffee I will be able to make. Not so with the Elite 30.
The most recent update has helped. Prior to this jumps of 20-30% were common, but pretty random, so it was impossible to estimate run time for the kettle. It is still not as good as the other batteries though so I am really hoping that by giving Bluetti as much detail of a real life use situation as possible, a further, more completely successful update will be able to be made.
Hi @VSM, Thank you for your suggestion—we find it very helpful.
We confirm that the new BMS v108309 has been pushed. Please upgrade and test it afterward.
Wish you a pleasant weekend!
@BLUETTI_CARE
Upgraded to v108309, fully discharged (922Wh output from 750W load, slightly less than original 945Wh), charged, and tested.
Everything is still the same, maybe even slightly worse.
SOC is at 56% rn after 24hrs of AC discharge with no load, just like it was at the very beginning.
It was at 85% after 5 hours (3% per hour on average), then 90 minutes later it dropped to 79% (6% in 1.5hrs = 4% per hour). Then I went to sleep.
The 40-watt load is still displayed as 64 watts, and the 60-watt load as ~90 watts.
I can wait another ~60 hours till it dies to measure if idle consumption changed (it was 85 hours), but I see no point. This firmware renders this unit unusable for small loads/inexperienced users anyway.
Now what? Wait an indefinite period of time for another version?
Tell Bluetti headquarters that I wish them the same experience I’m having right now - dependence on their own products with bugged firmware during extreme (in my case, war) conditions, which takes months to fix.
It is late 2025, and this is your 3rd or 4th gen of products; you have no excuse.
I wish I could just return this unit and get ecoflow delta something instead, since they already fixed their bugs (it’s been a year after their release), but I despise ecoflow even more.
Hi @Tezzabee, Thank you for your feedback.
We would like to push the latest BMS v1087.06 to your new unit. After the upgrade, please recalibrate and test it—we believe the new firmware will perform better. Do you agree to this?
Please let us know the SN code of your new Elite 30 V2, and we will proceed with the application.
Meanwhile, we have also submitted the issue to the testing department for reproduction and testing, and we will contact you once we receive a response.
@BLUETTI_CARE
1st pic, electric blanket set to 60 watts, I marked 3 indicators. Which one is lying in your opinion?
2nd pic, my pc on idle, which is ryzen 5600G with 3 fans and no videocard + Samsung S24R350 20-watt monitor. 128 Watts is a 148% increase from the factual 51.6 Watts.
3rd pic, I increased the load to ~195 Watts, which shows as 280. “Only” 45% measurement error this time.
4th pic, PC + 750W heater, absolutely spot on, no problems.
Send this to R&D and ask them if this is considered normal and user-friendly operation, and why my other 2 Bluetties (AC180P and AC200PL) are not like that.
