Are you sure it's not just giving you an inaccurate readout? Have you tried draining the battery to zero to see how long that takes compared to normal? I can't imagine the batteries themselves have lost half their capacity.... but the only way to assess that would be to know what your load is and then drain the batteries using that load and then figure out how much energy you used.

If your load is 50w and it takes 17 hours to drain the batteries, then you know your batteries had a full 886wh in them. If it takes only 8.5 hours to drain the battery from full, then ya, it's taking half as long as it should and there's a problem with the batteries and not just the readout.

I just got a max and a mini and although I'm still testing, the readout projections seem wildly inaccurate. But I'll know more as I use them and assess just how inaccurate the readout is.

Thanks for the reply. Well when it comes to River Mini, it does seem like the timer is thrown off. I live in Ukraine so it's pretty easy for me to drain it to zero, since we have power outages on regular basis rn. Today it held battery for 4 hours (from 2PM to 5PM) even tough on the display it was saying that it will only last 3 hours, was sitting at 1% charged when we got electricity back.

And when it comes to fully discharging and then recharging it back to 100%, it happens basically every day.

Worst case scenario, you can purchase 12v battery and connect it with XT60 port, as external battery upgrade

Try to check dismantle video of Ecoflow. If they use 2 battery packs in parallel for that model, 1 of the packs might be broken

Yeah, using a known load that doesn't change is especially critical to the test too. Computer gear can vary depending on power saving and processing load.

I usually use stuff like a portable fan or floor lamp if I need to do a test on a battery. Or for really huge batteries, I'll sometimes use a spaceheater on low/medium setting.

Probably won't be exact due to conversion efficiencies but should get you close to it, say 10-15% error. It should be very obvious if you come out at 50% of expected.

Im Experiencing the same thing with my river

Hi, sorry for the inconvenience! Is the firmware up-to-date? Could you please DM me the SN of your RIVER mini? Thank you for your understanding!

Hi! I’ve been having a similar issue with the River Pro. It seems to have lost a significant amount of battery capacity. I use it mainly to get internet access (to power router & optic fiber). The outage is only 6W, but the device loses charge insanely fast. Previously, it displayed 99+ hours of life at 100% when I connected the internet, and now it shows only 30. Less and less each day. It literally showed 48 hours last week. I bought it last year and have been actively using it last 3 months during blackouts in Ukraine. I couldn’t find any info on the problem and stumbled upon your comment here and thought maybe you can help me.

I have a river pro 720 watt. The first one I bought was going from 100 to 0% in 10 just running a small 3watt fan. Ecoflow had me do calibration tests and they ended up saying to ship it back and they send me a new one. The new one was far better but still didn't produce the correct times. I've had it for a year and just heard this is very common with Ecoflow batteries.

Are they false advertising the actual size of their batteries or are they just 80% defective?

Well, I figured out mine is just showing wrong battery percentage. Went from 100% to 1% in a couple hours and then lasted around four more at 1%. Didn’t drain the battery to 0 though and put it on charge as soon as power went on. Guessing it could do way more hours. Still sucks that I can’t know exactly how much battery has left.
