This is the listing. Surprisingly it now says 320 amp hours not 310. The seller is morecell battery store. also I added photos to the batteries themselves.

Hi, I am trying to get some feedback for an idea that popped in my head lol. I wanted a truck bed cover for my truck that I just bought but don’t want to spend the money for one. I also have 2 250 watt solar panels that will fit my truck like a tonneau truck bed folding cover. But it would be a...

ok i will look into those fuses and the double pole solar disconnect. The heat shrink with appropriate colors and bus bar covers. Thank you

Not specifically solar related but under the concept of “green energy” none the less. Don’t mean to discourage anyone from getting solar but I think u should get solar for the right reason. I am getting solar and lifep04 batteries myself but not to save the planet. It’s not a perfect movie and...

I bought a 12 volt 20 amp hr miady battery from Amazon. I’m brand new to batteries, solar and electrical work so I don’t have the proper tools to do a capacity test but I managed to get a rough capacity test. The rated capacity for this battery is 256 watt hours. I managed to get just over 200...

Dumb question here but is this normal for all lifep04 batteries?

Hi, I have a question reguarding this ATS Will Prowse reviewed a while back. The manual states the maximum current of ATS is 50 amps and 1200 Watts max load for my 24 volt Battery bank. Is this true? I dont understand the logic behind this bec the ATS gets AC power from the wall and 120 volt...

I bought 8 310 amp catl cells on Ali express and after inspecting them a 2nd time and adding the bus bars I noticed 2 of them r bulging to the point they can rock back and forth with another cell. To my limited experience they seem to be brand new grade a like the listing said visually wise...

These were all taken at the same time. As u can see the cells r still charging. They r approx 3.37 volts per cell. Is this bulging normal?

Ok fine, I’ll do it without emotion. But don’t delete this bec u don’t agree with me. U asked the question not me. Ur asking how we slow climate change? The only answer is we can’t. I’ll ask u a question. Does it make a difference if the climate changes drastically in 20 years or 200 years? In...

Ok I will apply compression when charging. I have been watching the individual cells closely while charging. I have limited time with these cells before the wife gets back lol. I have been charging in series during the evening/night and then set them in parallel (no charging) during the day...

Like damn, I am waiting for my 8 310 amp hours to come in. And I just stumbled on these.If these r legit I wish I would have waited a month!

Curious if I plug a 48 volt or any power supply into a mppt scc to charge my 24 volt batteries would that work?

Just curious about something that crossed my mind specifically about miady batteries but all lifep04 in general. If all bms have balancing features technology if u charged at an extremely slow rate like 1 amp an hr wouldn’t that be sufficient for the bms to balance? Or slower? Say .5 amps an hr...

I have watched many of Will Prowse videos on YouTube and he never recommends using the load ports on the solar charge controllers and in fact he suggests against it but leaves no explanation why, At least that I have seen. My understanding of load ports on solar charge controllers is that the...

When a bms says it’s 100 amps is that bi directional? Like u add the amps going into the battery for charging and the amps being used by the inverter?

I looked up not sure what to call it, percent of charge? And I keep getting stuff like this showing as little as 3.4 volts per cell as 100% state of charge. But I’m dumbfounded Bec I was told the 100% was 3.65 volts. I know lifep04 have a steep curve at the ends but that’s still conflicting...

I understand. So I have charged the batteries to 3.44 volts, what percent of charge is that? Bec this picture is showing the “resting state of charge” or whatever. I wana know what percent did I charge my batteries to. Is that possible with just using a voltmeter? Or is a shunt that’s purpose...

I’m trying to change the “total battery capacity” to my actual capacity to 7936 amp hours but mah hrs it’s 7936000. The problem is the user settings in the amp don’t allow 7 characters only 6. How do I set the proper amp hours?

I ordered 4 280 amp hr Eve cells from liitokala on Amazon from wills suggested list on feb 15th 2021. On April 6 after I emailed littokala 4 times over the course of 6 weeks (to get an updated tracking number bec the one he provided was fake) and no answer he FINALLY emails me back on week 7 of...

Ah nvm stupid question. I got it. How do I delete this?

ok my 150 amp breaker is on the battery. I have my battery, wired to a battery shut off, to my 150 amp breaker, then to my terminals that the bus bars connect to.

I am top balancing but not wanting to go to the maximum of the 3.65 volts due to some cells already expanded prior to me doing anything. I have them under compression but I understand charging to the max voltage makes them want to expand further. I was aiming for about 90% full charge or top...

I was very curious on overkill 24 volt 100 amp bms.

Has anyone heard of these new cells on AliExpress? R they legit?

So to nail it in, u have to top balance at 3.65 per cell. Anything less then that is not a proper top balance?

Ok thanks

Thank you! That explains a lot.

https://hbr.org/2021/06/the-dark-side-of-solar-power This is what Michael Moore was saying.

If I do option 1 do I replace the converter by taking it out completely and in it’s place add the 24 -> 12 step down ? I would disconnect the breaker that powers the converter as well bec the 24 volt batteries would do that. Correct?
