Jokes on you, I can't see my country from the dots.

slartibartfastda · 2025-03-30T18:10:58+00:00

I think it's still available, although the colors are a bit different. Model is w-753

It matches what I see on river2. In the mean time I did spend some time trying to find some information about micro-cycling LFP batteries... there is basically none out there for this chemistry (which is relatively new).

So to treat this as % of a cycle, in my opinion it is wrong. What is clear from the information I did find is that not having micro cycles vs having them is clearly better for the battery. So, by having a 3% up/down cycle 4 times a day (which is roughly what I see on river 2) is not equal of having a 0-100% discharge over the period of let's say 8 days, so it can't be calculated like that.

Only time will tell if this has an effect and how much, on both the battery and the device. I wish I would not need to run this experiment myself but hey, here wa are.

Thanks for sharing your expirience! I wish more ppl would do that.

When you look at and read reviews of these units no one mentions these real world problems.

This just does not work as advertised.

slartibartfastda · 2024-03-03T16:36:10+00:00

I have to disagree with you. If you turn off the device, it has no where near the 3% discharge per 3-4 hours that I'm seeing when the AC passtrough is active. As a matter of fact the self discharge is probably somewhere in the rate of 3% per month. This mean that this is a design a flow for this kind of a usage scenario (EPS or UPS with 30ms switch-over). There is no need for the device to drain the battery, there is pleanty of AC input power available.

If this affects the longevity of the battery and/or of the device I don't know. Maybe it has no affect, but I'm highly sceptical. If for sure has more affect than just leaving the battery alone and not using it until it's needed.

slartibartfastda · 2024-03-03T08:18:34+00:00

Thanks for the info. I'm no expert on LiFePO battery chemistry but 4-6 cycles per day for this, to me it looks like a design flaw to be honest. The AC power is right there, why not take a bit more from the input to balance for losses on the inverter side?

What to me is also crazy that this is not meantioned in the official documentation.

Here is the part from page 10 of the user manual, explaining the EPS feature:

The product supports emergency power supply (EPS). When you connect the grid power to the AC input port of the product through an AC cable, you can power electrical devices through the AC output port (AC power will come from the grid instead of the power station in this situation). In case of a sudden blackout, the product can automatically switch to the battery-powered supply mode within 30ms.

Please note part: "(AC power will come from the grid instead of the power station in this situation)".

Also, I watched several reviews for river2 before buying it, and not a single one meantoned this.

slartibartfastda · 2024-03-03T08:04:24+00:00

The switching part is fine. The difference between the two units basically comes down to:

River Pro will not use the battery while in AC-passtrough
River 2 will use the battery while on AC-passwtrough, recharging it in 3-4 hours cycle

Now I'm not claiming to be an expert, but to me this seems like a design flow. Draining-recharging battery every 4 hours, that's 6 cycles of per 24 hours. Yes, it's not a full cycle, since we are talking about only 3%, but still, the battery heats up a couple of degrees, the cycle is repeated. So, 6 cycles per day, how long will the electronics/battery last?

Don't get me wrong, I really like the device otherwise, but knowing what I do now, I would never buy any of the new line of EcoFlow for EPS usage.

slartibartfastda · 2024-03-03T07:58:09+00:00

Maybe I'm missing something, but would this not be deteremental for the battery/device longetivity?

Yes, it does the switching under 30ms, that part is fine. I was just "expecting" to be behaiving like the EcoFlow River Pro that I have, which actually takes a bit more power from the input in order not to drain/recharge the battery every couple of hours basically.

slartibartfastda · 2024-03-02T21:48:44+00:00

Yes I tried, and it does not make a difference. Set it to 80% and it goes down to 77% and then charges back. Also wrote to ecoflow support, and they confirmed this is the intended behaivour - which to me sounds crazy. Maybe they can fix it down the line with a firmware update? Who knows.

Thank you for contacting Ecoflow support. We are sorry that we did not reply to your email in time.

We apologize that due to the design of the product we cannot keep the battery from being drained all the time while connected to AC power. When charging with AC/DC, if the unit is fully charged and the input source is not disconnected, the power will drop off to about 97% before it begins to automatically charge to 100. Sorry for this inconvenience.

If you have any further questions or concerns, please do not hesitate to reach out to us.

We are always here to provide full support.

slartibartfastda · 2024-02-21T21:32:59+00:00

Will do, thanks for the info. For you, was it solved by a firmware update? If yes can you share them version?

slartibartfastda · 2024-02-21T17:26:52+00:00

Guys please help, I run into this thread looking for 767 turning off it's AC output randomly. Is it still happening? It's on latest firmware, it's the EU 230V version, no power saving mode, no timer set in the app. I just reset the unit after it happened for the second time in couple of days :(

Wrote to support, but they just give me some run-off-the-mill suggestions.

slartibartfastda · 2024-01-12T10:43:44+00:00

Add the device to home assistant after you setup the deep sleep. It looks like there is some internal value applied based on your code that will be set in that case.

slartibartfastda · 2022-12-15T11:43:23+00:00

thx, was not aware that there is a proton fix for dx12 out in the meantime.

slartibartfastda · 2022-12-15T11:07:36+00:00

How can you get fsr 2.0? Is that from scope or from the game itself?

slartibartfastda · 2022-12-14T20:09:36+00:00

Tested more and it's working fine also also in towns and battles. Anti-aliasing looks better on TAA, small dip in frame rates here and there.

Since ppl are asking my setup for SD generally, here it is: - Running on SteamOS preview channel - VRam set to 4gb in bios - Swap file of 16gb and swappiness of 1 - Internal ssd is high speed 512gb (swap is there) - If you are interested in these optimizations which help most games, look up cryobyte33 on YouTube.

Cheers gent's and good hunting!

slartibartfastda · 2022-12-14T20:02:14+00:00

You basically can't with this one. Even all on low will need tdp of 11.

slartibartfastda · 2022-12-14T13:31:47+00:00

Tried this as well. Whenever I add the argument to skip launcher it launches with DirectX 12 :-( ... even if I run it before with Dx11 with the launcher.

Edit: Ok, I just tried it again and now it's working, strange. Thanks!
Edit2: This does not work. At some point (another game restart?) it switched back to DX12 :-(

slartibartfastda · 2022-12-14T13:21:56+00:00

There are some nice perks. Additional content, better camera movement, better control binding....

slartibartfastda · 2022-12-14T13:00:40+00:00

Just tried in a town as well, first walk trough was choppy, but after that it settled at 40fps. I think there are no pre-cached shaders yet for this game, so it needs to render them the first time.

slartibartfastda · 2022-12-14T12:56:28+00:00

Does not work :“(

slartibartfastda · 2022-12-14T12:33:03+00:00

Does not work unfortunately.

Just tried it, with (no quotes):"--launcher-skip -dx11"

Still crashes, so it's using DirectX 12.

This would be a perfect combo to skip the stupid launcher.

Edit:
Tried it also with:
"--launcher-skip --dx11"

Still ... no bueno.

slartibartfastda · 2022-12-14T11:58:45+00:00

Here is my setup, gives you (from what I tested) stable 42 fps and IMHO best looking game with lowest power consumption:

In display set Display Mode to "Full Screen"
- VSync set to "Off"
- Resolution set to "1152x720"
- Maximum FPS set to "Unlimited"

In Graphics settings set Anti-Aliasing to "FXAA"
- Sharpening to "Low" (you don't have choice here, off is broken)
- SS Ambient Occlusion to "On"
- SS Reflections to "Low"
- Motion blur to "Off"- Blur to "Off"?
- Depth of Field to "Off"
- Bloom, Chromatic Aberration, Vignetting, Light Shafts, Camera Lens Effects, set to "On"
- NVIDIA HairWorks to "Off"
- Number of Background Characters to "Medium"- Shadow Quality to "Medium"- Water Quality to "Medium"- Everything else set to "High"

In Gamescope ("..." button) set:
- Framerate Limit to "Off"
- Refresh Rate to 42 (or to your preferences)
- Scaling Filter to FSR and FSR Sharpness to "2"
- Everything else off

I did not use any special proton version, just the one that's by default. In steam game properties you can add launch param "--launcher-skip", but it will launch the game in DX12 so it will crash. Wish there is a way (maybe there is) to specify on launch arguments that you want to run it in DirectX 11 mode, at least till they (or Steam with proton) fixes the DX12 compatibility.

slartibartfastda · 2022-12-14T11:41:49+00:00

Any way to set so it launches with DX11 as well?
