Yeah. I would not trust that. If it is LFP it would say Lithium-iron Phosphate or LifePO4 or LFP.

Answer from manufacturer below.
I did ask about battery chemistry also - not answered.
What do you think ?
Hi xxxxx
Please find the attached brochure on the Nano 750.
The unit has a 2 year warranty or 2000 cycles whichever comes first. ( 1 cycle is completely charge and discharge)
The unit is a 750 watt hour battery bank with a 300 watt inverter, but because of the 80 % DOD ( depth of discharge) you have 600 watt hours of safe usable power.
The unit should not be discharged below 10 % as this damages the battery.
The unit has an alarm sound to alert you that only 10 % is left available.
The weight of the unit and the box is 10 kgs
The unit itself is 7.8 Kgs

2000 or 2 year warranty? That does not sound like LFP
Typical LFP has 5+ years on em. (ie: My LFP has 10 year warranty)
If it is LFP they must be using B or C grade or something, which also explains the 2000 vs normal 3000 cycle life.

Sounds like 18650 cells, the cheap ones.

18650 normally come with 350-500 cycle warranty so not that either?
New LiPO chem is about the closest but they normally rated 80% on 1000 cycles.

I think its more on the manufacturer of the cells and their chemistry formula they use for their cells, Take the Greenrick batteries for example. They use 18650 cells but the battery warranty is a cycle count of 6000 at a 95% dod.
Their spec sheet seems to be a little bit sus.

XT60 cable and solar panel arrived. Think I'll definitely have to figure out a way to mount the panel on the roof. Due to the size the panel will be a tad too cumbersome to take in and out each time I want to charge the Ecoflow.

So better to wait for the ecoflow delta/river 2nd version coming next year early ?

I will not deny Ecoflow has its place in the market for its ultra portability and some of its features, but if you really not going to be lugging it around and just have it kept at one spot, rather look at a bigger system with more battery back up and a longer warranty.
Had a customer with the delta Pro, that just has a TV,router,soundbar and DSTV. shocked the heck out of me when I was told that and still wanted another for his PC but then again customer wants what they want.
Do you need something ultra portable to take around with you places or would it be in a fixed spot? There are inverter trolleys with Lithium options that also do make them quite light.
I think the main reason that many people are getting these is because they are renting so they cant have a fixed installation.
Portability is good to have because one can easily move it from one spot in the house to another as needed. e.g. move to room to use hair dryer, move to kitchen to use pressure cooker, move to living room to use the TV etc.

Couldn't agree more with you there. Initially did that myself and a ton of extension cords till I got a fixed unit. RCT 2kw inverter flat mounted on a box with lead acids but lol lugging around lead batteries not fun at times. Especially to get up stairs.

The scenario is as such - I have a generator with manual change over switch.
It is about R100 for fuel for a load shedding session.
It is very convenient cause it can pull everything in the house and I have no problem running it for instance in the mornings or early evenings when people want to run microwaves etc.
Now sometimes during load shedding my only requirement is to run the Tv + soundbar, or just one PC in a bedroom, them it feels a bit of a overkill to run the generator. So portable within the house would be a requirement, maybe 20kilos max (no idea how much they weigh).

The River max and that one that you linked to was around 7Kg.
The nice thing with the Ecoflow units is that they charged very quickly so if you have a prolonged outage you can charge it quickly via your generator and then turn the generator off use it to run some essentials...
Could be useful to run a small freezer for several hours during the night for example.
Says 10 hours to full recharge according to the spec sheet here.

I have the Genki 1000, and while this thing is quite freaking awesome - it is noisy on AC.
Even if pulling really low wattage - like a TV - the fans kick in from time to time - and if in the bedroom, you're awake.
I tried using it as a replacement to my inverter + 2 * deep cycles, but that fan... It kills me. Runs my rig etc... no problem, but on AC - those fans are a killer in any environment when they kick in.
I would have thought they pass through when on mains (like my current inverter), but nope. Mains or not, those fans are gonna get you.
Anyone got tips or tricks to replace the fans, update firmware, something? I would love to make better use of this thing as a UPS, but for now - it just a big ass power bank the does some USB stuff.

Question for Ecoflow owners: I have my River Pro set to charge to 85% charge. I've charged it up today for the first time and when it reached 85% it kept on charging at 20W or so. And it shows the time remaining to charge as 7 hours. Is that normal?
Crusader

Yes. I have it on slow charging.
Edit: Okay, I plugged it in again and now it doesn't show any input since it's on 85%. I'll keep an eye out and see if it gives the same issue again. Might be that I didn't give it enough time to fully charge to 85% the first time round.

4 hours in on the River Pro + Extra battery (load has been pretty consistent at around this mark)
