That was a LOT of tests!!.... GREAT job on the time that you took to make this video. I also enjoy seeing all the VERY positive comments from those who own these batteries also! Keep up the great work!! Thumbs WAY UP!!!!
If you are using the "BMS tools" software it appears that the software will only speak with 1 server rack battery at a time. If it's important to see all your batteries in your server rack at once, the Lifepower4 battery with the "BMS Test" software is apparently a better option allowing you to view all your battery in your server rack.
FYI, I have three EG4-LL V1 batteries, and they are all connected via an RS-485 Hub to my laptop, and the BMS_TOOLS can communicate to all three batteries without moving the RS-485 cables. Of course, the software can only display the data from one battery at any time. However, by changing the Pack ID, one can look at the data from whichever battery without moving cables.
I want to build a mobile onlo run the fridge during our occasional power outage. I was thinking of using the LiFepO4 battery. Would you still recommend it or would you switch to the EG4LL. Most used to run the Fridge or charge the Delta Max 2000. No heavy loads.
If you have no heavy loads I guess the lifepower4 battery would work for you. Are you wanting the 48-volt version? What inverter would you be using with the battery?
@@diySolarPowerFunWithRay I went and bought the eg4LL battery you have in this video. I also bought the eg4 3k inverter/charger and realized after I received it that I would not be able to charge it via solar as I don't have the solar panels required to produce the voltage. I found a work around and bought a Victron 100/20 that will accept my solar panels and will trickle charge the battery only. All in all I love this battery. I'm learning as I just got into this and it is fun and addictive. Another work around I can use is to charge it with my ecoflow 2000 power stations while I charge them with solar. I know it is not efficient but solar power is free. I really enjoy your channel and am subscribed. Thank you for your hard work.
Hi, considering the Will P EG4 trolley setup (easier than diy), but the batteries are out of stock. In stock are these LL ones, no idea what LL means, google brought me here, still no idea what it means. All that stuff about the air conditioner was confusing. Simplified, lets pretend your setting up 2, their all the same price, which would you get?
Hi Ray! Excellent video! I'm considering one of these batteries so I watched closely!! When you showed the display of battery voltages I was a bit surprised... it doesn't show individual cells, but the cumulative voltages. Isn't that pretty much useless? How do you spot a cell that has slightly out of spec voltage? You can't read each value and use a calculator to subtract! That's just silly! I'm curious what you think about that!! Thanks!
Hi, Thanks, If you look at around the 2 minute mark it shows this. It shows MiliVolts. You'd love this battery if you get it! It also comes in 12 and 24-volt models: 48v : signaturesolar.com/eg4-ll-lithium-battery-48v-100ahd?ref=DiySolarPowerFun 24v: signaturesolar.com/eg4-ll-lithium-battery-v2-24v-200ah-server-rack-battery/?ref=DiySolarPowerFun 12v: signaturesolar.com/eg4-ll-lithium-battery-12v-400ah-server-rack-battery/?ref=DiySolarPowerFun
I went to the website for the battery clip on covers and didn't see them there. Sorry I didn't see this video before ordering, any chance you can share the .stl file so I can print my own?
Just make sure you buy one that will limit the the amps because lifepo4 batteries call pull a ton on amps. A couple weeks ago I posted video on a van electrical system. You should check out the device he used there. That's what I'd I l use

HOWdy DIY-S-F-w-R-L, ... Thanks for the REVIEW ... I currently have THREE of these EG4-LL (V-2) & THREE of the previous EG4-LL ( V-1) Batteries So far all of these purchased in 2023 & quite happy with their performance I would have purchased the LifePower4 batteries = but the WARRANTY was a lot
How long will this battery last with a constant 1500 watt space heater load coming off the EG4 3000 inverter. And how long will the battery last with a constant 750 watt space heater load.
The battery has 5120 watt hours of capacity. so running a 1500 watt load with around 50 growatt idle would be.... 5120wh/1550w = 3.3 hours. minus a bit for 85% - 90% efficiency.... So i'd say just under 3 hours. Half that for the 750 watt space heater.
It was not clear, you are saying that the EG4LL is the best battery on the market but then you said that if you bought a rack of batteries you would use the EG4 LP4 for that. If the LL is the best battery you have tested why would you not use that for a rack of batteries. Thanks for the great video as I am considering a full battery rack.
For a full rack of batteries, I would get the life power because I would be saving money. About the equivalent of getting an extra battery for my rack. If you have six batteries for your rack, any large loads could be handled fine because the amp draw would be split across all six batteries. If money is not that large of a consideration or if you just want the best, definitely get a rack of LL batteries. Hope that helps. If you buy the LL batteries and use my affiliate links i will mail you some battery protection clips.
I like to do something similar offering reviews for discounted products. How much did they take off the $1750 retail cost for your review & did you reach out to Signature Solar to offer review? Thanks.
Like I mentioned in the video I did get a discount. Otherwise I would have not reviewed this battery because they are more expensive. But I am glad I have this battery now. Feel free to email me
I know that sok recently came out with a competitor budget server rack battery. Similar to this one but it doesn't have the Communication cable for closed loop communication. I hear good things about the sok batteries but I have never tried them.
This EG4 battery pack is not UL9540 rated for residential installations and as such, home owners will not be able to legally obtain a permit for its installation in the U.S. You are doing your viewers a disservice by recommending this product for residential installations.
Just pull the trigger on a mini split. They use almost no power. There are a lot of cheap brands that aren’t variable rpm pumps. We dozens of Senville units, from 18k btu to 24btu arctic pump. They heat and cool amazingly.
@@diySolarPowerFunWithRay agreed! Lithium Ion aren’t worth it, and LiFePO4 are new to market because chinas patent ran out. So now we can get them. Our calculations are one of these replaces 8 100ah AGM batteries for our purposes. So cost is almost the same but performance is a better and longer life.
I've worked in customer support for over 20 years and managed customer support "help desks" for fortune 500 companies as well as government. That said... my EG4-LL went into protection mode and the customer support I was given by EG4 was among the worst I've ever received. No instructions, no follow-up, no competence. Still not fixed and I'm about to flush my 48 volt LiFePO4.
The price for them batteries are ridiculous Signature Solar cater to the rich i built my own lithium battery bank because if Signature Solar was the only solar provider a lot of people wouldn't be able to afford solar at all
Did you mean 2k? They did answer the phone right away, and they didn't put me off... they kept on trying until we got it working. They have a lot of products to support. In this case, it did take an hour. Which is definitely longer than the norm. With signature solar, they have been going through some Growing Pains, and I have had some technical support people that weren't as informed as others. But in the end they have been able to answer the questions I've given them.
@@diySolarPowerFunWithRay we tried to link Lance channel so you can see how he dealt with EG4 supports but looks like TH-cam block it. Any way search for EG4 batteries and his name is Lance K.
@@adassociates8235 Thank for sharing. I looked him up and his review of this battery. It looks like he was able to get support from signature solar but he wasn't happy with using this battery over the Lifepower4 battery when grouped with other EG4-LL V2 batteries. I agree with him. when you want a stack of batteries I also recommended the Lifepower4 batteries over this one. It looks like the BMS tools software that speaks with this battery isn't as good as the "BMS Test" software that works with lifepower4 batteries. That's good to know, I wasn't aware of that. I'll pin it as a comment here. I still very much like this battery if you're only going to buy a single battery for your system. thanks for sharing.
@joshhartin78 I haven't done it yet. I haven't needed to and they are a hundred pounds each so it's kind of a pain to put them together. I'll do it in the future as a short though.. good idea.

I have 6 of them arriving tomorrow, nice to see the performance!
Yeah, they perform really well. You'll love them
Wow, really great video. I learned quite a bit, great job!
Thank you. You guys are great!
You can always look at the EG4-LL SOC value and type that number into your Victron Smartshunt, in order for both to report similar SOC values.
great review. appreciate all the demos.

Does the "same" battery but one grade down from SS have the fire suppression and the ramp-up capacitors to make it easier on the inverter?
Are you referring to the LifePower4 48v battery? It doesn't have fire suppression.
Does your Growatt inverter have pass through charging to charge the battery with a generator for extended cloudy periods?
Yup. You can set it to use the pass through charging boost the battery to a specific % once it gets low. All configurable... very nice.

All that stuff about the air conditioner was confusing. Simplified, lets pretend your setting up 2, their all the same price, which would you get?
Hands down...I'd definitely get the EG4-LL V. The LifePower4 doesn't have great starting power on it's own.
How many BTU on your air conditioner ?
What is the temperature of the air conditioner at startup?
Sorry, I'll try to check this on Monday
Would you do the installation for customers

Could you charge a 48v Lifepo4 battery from a 12 volt boat engine alternator using a 12 to 48 v DC converter?
Just make sure you buy one that will limit the the amps because lifepo4 batteries call pull a ton on amps. A couple weeks ago I posted video on a van electrical system. You should check out the device he used there. That's what I'd I l use
It says version 1 because of the firmware not the battery.

HOWdy DIY-S-F-w-R-L, ...
Thanks for the REVIEW ...
I currently have THREE of these EG4-LL (V-2) & THREE of the previous EG4-LL ( V-1) Batteries
So far all of these purchased in 2023 & quite happy with their performance
I would have purchased the LifePower4 batteries = but the WARRANTY was a lot
It looks like they just updated the LifePower4 battery warranty to 10 years to match these.
