I think tiny baby has been doing a good job at the lift tests, but I think he's capable of doing more; That said, I think he should be promoted / also in charge of lighting the batteries on fire, in order to test their fire suppression capabilities. Looking forward to that video.
The amp rating goes up toward the end of your test because the voltage is dropping. Amps * Volts = Watts. Your load drew a constant wattage, so as the voltage curve drops toward the end of the battery's capacity, it needs to deliver more amps to maintain the same power output.
Anyone who doesn't understand this shouldn't be making videos.
Sweet. Thanks fellas
Was waiting for this one, glad to see you gave it such a positive review! I'm going to be buying 60 of these batteries (yes that is 307kWh worth) for our new fully off grid property. We are going to be buying 10 racks of 6 (with the integrated server rack). This is going to rock! Glad to know I am not making a poor decision using these batteries.
I think we all need photos when that install is finished!
You must be rich or something
How many of those batteries do I need to run a 24000 k btu air conditioner?
@@kurtrhaburn9159 Way too little information to answer your question.
I’ve seen nightmare stories with them. The big problem is the batteries get unbalanced or one battery goes bad, then how you repair that?
I build my own with 280ah batteries for that same price.
can you post any of those stories with links here for us to follow up ourselves that are looking at this brand?
Not true that is what the BMS is for it manages the individual cells
From what I have seen, if the batteries themselves are not staying around the same soc, then they are likely not getting a good regular 100% soc charge. I typically recommend at least monthly 100% soc charge to keep all the batteries close together.
Great video. Quick and to the point. If I already have a few EG4-LifePower4 48v 100AH batteries in a rack with communications working can I add the LL batteries to in the rack to the same battery bank?
Liked and subscribed!
how does the fire arrester work?
Great video, I can't have anything like this because I live in an apartment but, out of all the other indoor options, what brand and set would you recommend? My energy needs are around 500kw per month during nov-apr months and around 800 may-oct. I was looking at ouikitel BP2000 pro plus a battery to make it 4000w.
I'd appreciate your answer.
When putting these modules in parallel, does the module voltage need to be close to each other? Or is it not an issue with these modules?
Hmm interesting. Do u think this would actually be better in my van build over. Ecoflo power kit or ultra ??
Where are you getting the information it's the most popular rack style battery on the market? Which market?
The model without the screen has no built in circuit breaker and only a 6 year warranty vs the screen version with built in circuit and a ten year warranty. It’s not just about a screen or no screen.
nice
The difference between this and the less expensive LifePower is more than the screen.
Great video, guys!
Nice work on this one.
Which one do you recommend 24v or 48v for a Growatt inverter?
Your inverter needs to match the batteries. With 24v you've got a lot less options in everything.
How many of those batteries do i need to run a 24 k btu aircon?
Way too little information to answer your question.
Excellent honest throw it around review, awesome 👌 your show rocks!
Do the eg4 solar ac!
Great review!
Hi : would love your recommendation for a portable home power source solution. We are in Texas. A Hurricane just came and we’ve been with no power for 72hours. So basically we want to prevent this from happening again in the future. Looking into a mobile solar power solution that can work to power our fridge and some kitchen appliances (we have a gas stove so don’t need it there ) and maybe TV and internet. We have 3 HVAC units so not sure if those things are powerful enough to power at least one of them. Looking into Anker SolixF3800, Ecoflow Delta 3 Pro, Ecoflow ultra , Jackery 2000 plus. A system that it’s easy to use (don’t know anything about electricity ) and that we can grow into as time passes. Would love your recommendation and an affiliate link to help your with the channel
Sorry to hear that your going through that right now. One of these units is definitely a good idea! By the sounds of what you need, i think the F3800 or the Delta Pro Ultra are probably your best bet. The Delta Pro 3 is good, but has a smaller inverter then both the F3800 & Delta Pro Ultra and wont be able to power as much all at once.
F3800 is cheaper, and you can grow into it very easily in the future. smaller battery if you just buy the unit, so it wont last as long as a Delta Pro Ultra, but a good size inverter.
Delta Pro Ultra has a larger battery, so it'll last longer, and slightly bigger inverter (not much). You can also grow into it easy, however it has a higher price tag.
You cannot go wrong with either unit. Here is links to both, however i'm not sure if the links work in comments so if they dont - go to our review video about the unit you prefer and click one of the link there! Thank you & Good Luck with everything 👊🏼

I’m also in Houston and still without power since Monday 5am. I’ve been running my side x side fridge, deep freezer, coffeemaker, blender, 3 fans and internet non stop. I don’t have ac but the fans have been getting us by. I’m lucky that a close neighbor has power and I’ve been recharging my portable solar generators daily. I’ve estimated that my consumption is around 350-450ah for 24hrs so thats about 4500-5700wh of use a day. I hope this helps you better understand the demand you might need. If I powered a window Unit ac for just one room you would need double that power consumption per day. By the way my power is still out.
The bigger issue is usually recharging. The storage capacity itself is mostly only needed to bridge overnight. So you run loads + charge the batteries during the day and the battery continues running the loads at night.
That means, generally, having enough solar to produce around 24 hours worth of energy for your loads. Alternative means of recharging help a lot too, such as having a small generator. Having a battery storage system means only needing to run the generator long enough to charge the batteries and then blessed silence the rest of the time.
Its a good idea to know how many watt-hours your daily loads use. Add another 15% to deal with inverter losses and such.
In anycase, I'll plop down nearly the whole involved mess but my real advice to anyone thinking about doing solar from scratch who has NEVER done solar / power / batteries before would be to start really small (but stick with a 25.6V or 51.2V system voltage from the get-go)... small and cheap. Then scale up from there once you've gotten your feet wet and understand what it all entails.
--
Typical consumption:
* Full sized residential fridge, averages 60W (a few hundred while running, nearly zero while not).
* A few lights, average 30W
* Induction kettle and microwave: 1500W x 15 minutes daily (three or four uses total).
* Internet, wifi-routers: Typically 10W per router.
* Internet, cable-modem: Typically 5W. Starlink would average more like 40W, fiber around 10W.
* TV: 30W
* Device charging: 30W x 1 hour a day, roughly
* SMALL HVAC unit: 350W (can cool one small room or take the edge off a medium-sized room) (note: mini-split style with a variable speed DC compressor, NOT a full home A/C with an AC compressor).
Inverter size needed: 3000W to be safe to ensure they can handle the fridge and the small HVAC unit's compressor start, and not trip on the microwave / induction kettle.
Now figure out the actual watt-hours (aka energy use) per day of consumption:
* Fridge 60W x 24h = 1440 Wh/day
* Lights 30W x 24h = 720 Wh/day
* Kettle, microwave: 1500W x 0.25 = 375 Wh/day
* Wifi routers (say just one): 10W x 24h = 240 Wh/day
* Internet router, say fiber: 10W x 24h = 240 Wh/day
* Device charging: 30W x 1h = 30Wh/day
* SMALL HVAC unit: 350W x 12h = 4200 Wh/day (assume 12 hours a day of use)
Total 7245 Wh/day
--
Add inverter overhead, assume 15% (another 1087 Wh/day)
Grand Total 8332 Wh/day. That's 8.3 kWh/day.
That would be 2 x EG4 LL batteries (10 kWh of storage), roughly, to have good margins and 24 hours of operation, giving you a good long time to run around like a chicken with its head cut-off when the power goes out. i.e. time to collect yourself and figure out all your options.
--
Then the solar panels required... divide by 4 to be conservative for panel nameplate wattage.
8332 / 4 = 2083 watts worth of solar panel could keep all that going indefinitely, at least in summer when the sun is shining. So 2kWp worth of solar (kWp = nameplate panel wattage).
2000 kWp in solar on a 48V system (roughly 51.2V) = 40A charge controller. Best to split the solar into 2 x 1000W strings, roughly, each going into its own 20A charge controllers. (Or find other solutions such as all-in-one's or other options, depending on how much DIY pain you want to deal with and maintainability of the system).

Already too long of a post. There are numerous system components, only slightly reduced by using an all-in-one verses discrete components. Panels, charge controllers, AC battery charger for generator interface, the batteries, the inverter, etc. Plus additional electrical items.. proper cabling, fuses, main battery fuse, additional breakers, and so forth.
The costs can add up quickly when one is DIYing a "large" system, which is why I always recommend that people who never dipped their hands into solar power systems start small to begin with.

Great information Matt, had some in-laws asking about a solar setup that would help them next hurricane and I told them just to buy a duel fuel generator enough to run fridge,WiFi,lights and portable ac. If you don’t live in an apartment or care about the noise that’s the best option.
@@Card_addiction And I should add, for an ultra simple solution that still gives you some peace and quiet, having a small dual-fuel generator coupled with a small or medium-sized power station is a pretty good combo. Two purchases and you are done.
You also save a ton of gasoline or propane because you don't have to run the generator to keep mostly-idle loads like a fridge active. You just run it to top-off the battery in the power station, then turn the sucker off until the next time you need to charge the power station.
-Matt
Wouldn't it be 'spec down'?, tear down is something different.
It’s a 51.2V battery.
Would have been cooler if you stayed committed.
Does it get heavier the voltage you put into it? 🤣🤣🤣
6:30 hey if you don't know how to talk about loads, surge, amp draw/support, voltage sag, etc. then don't even bring it up. One of these batteries cannot do nearly as much as you make it out.
Drop the music. Degrades the info.
To properly test this battery you need to tear down the BMS down to the component level and check the caps and FETs for their country of origin. If they're made in China. you can count on a shorter life expectancy than FETs and caps that are US or European made. Another test to perform is a cell impedance test to confirm whether or not the cells have been matched. We use a $6,600 Fluke BT521 advanced battery tester when testing for cell impedance. Another thing to consider is whether or not the BMS offers active cell balancing. If it does not, then as the cells age, and their individual impedance changes, you can expect a substantial capacity loss over time. Another thing to consider before buying this battery is the fact that for only a few hundred dollars more than what this battery sells for, you can easily DIY build a 48 Volt 300+ Amp hour (three times the capacity) battery with display, low and high temperature sensing and active cell balancing.
Do you have any recommendations on companies that sell the reliable diy batteries?
...not sure if satire of "just DIY it bro" posters or not.
If you are serious I would subscribe and pay to see you test electronics i.e. batteries, inverters, bms etc. You should start a CZcams channel. There are to many novice CZcamsrs like this guy in a fishing hat who barely knows the basics
@@zgomez68 Yes, watch the off grid garage episode titled "EVE MB31 314Ah Cell Test and Review. Have I gotten selected cells to show on the channel?" I just ordered 16 of the MB31s and will put them through thorough (real) testing and will let you know,
Your DIY battery Weil not come with a 10 year warranty, that may reduce the benefits of your suggested method.
8:55 really? You'd ground out a DC battery, which is low voltage, and get shocked? Well shit! Better start letting electricians know they are idiots and at risk. Weird how UL doesn't require coverage for such a "dangerous" exposed terminal.
Hey, I hope you have a better day tomorrow!
EEL batteries are cheaper
