ECO-WORTHY 48V 200Ah LiFePO4 Lithium Battery (2 Pack 48V 100AH) w/Bluetooth | UL1973 & UL9540A Certified | 10.24KWh Server Rack Battery for Solar Energy Storage, Home Backup Power

Seems very well built and worked perfectly. Packaging was great.

Why did you pick this product vs others?:Value of battery including capacity. Quality:Build quality is excellent. I bought the 4 pack plus rack. The cables that come with them are plenty to go from battery to battery in the rack. Ease of installation:Very easy to install in the included server rack. Functionality:Arrived about 30 percent charged. Packaged well. Easy to set up in my existing charge controller. Battery life:Can’t speak yet on battery life but for my off grid cabin they have ample storage, and have been installed for about a month now being discharged and charged every day by my array and outback solar charge controller / inverter. Weight:They are heavy but not excessive. It took two of us to install into the rack (because I had another person available) it would be possible to install in a rack by yourself but would not be fun. Battery quality:Presentable quality is great. All holes lines up, handles and terminals all were able to be torqued with a torque wrench without breaking. I will be buying more of these in the future to expand my capacity as needed ( or maybe if needed since I replaced lead acids)

Worth every penny. I bought this before watching videos. I fell into a gem here. Test exactly as it should. Cell are brand new and perfectly balanced. Within 2 one thousandths of a volt, all 16 cells. Communication works between my polwland 5000 watt inverter and both batteries. Wifi works, and I can check my charge from anywhere. I upgraded from Chins. Bad experience there. I'm building a home and documenting it in 360vr. I'll be using these for my whole home solar. Right now they're powering my shed and tools for the home build. No average shed though :) it has 2 a/c units, coffee maker, microwave, wifi, security cameras, big screen, surround sound etc...

Best price I found and good quality too ! Exactly what it should be !

I purchased 2 of these batteries for my off grid solar system. Overall I'm pretty happy with the batteries, but I was a little worried about the initial differences in the batteries power absorption. The first battery charged up to 100% within about 5 hours at 15 AMP AC charge from My sungoldpower AIO inverter. (small 5000Watt). I cycled the battery once using a 1500 Watt heater and it then recharged to a full 100%.The second battery, only charged to 96% and the BMS alarmed and shut down charging because one of the cells was full. So the max charge only went to 96%. I let it sit on the charger overnight thinking it might balance out, but it did not. Next I cycled the battery with the 1500 Watt heater and after that it charged to 100% (i just left it on overnight, and never checked on it).I still think these are a great value, but I'm a little worried about consistent charging, and the function of the LIFePO Cells, but really at this price, I think they will be fine overall. I will see how these 2 go, and report back if I buy more.I used the Will Prowse discount code to purchase. With that code it was cheaper on Amazon to buy the batteries individually instead of in a 2 pack (because of taxes and other charges).

I have 2 of these setup in parallel hooked to a EG4 6000XP inverter and they are working perfectly. You need to set the batteries to LUX in the communications and the battery type to 6 (LUX) in the inverter and they talk just fine. Make sure you charge it up fully before worrying about balance or how many AH you get. Straight forward and clean, easy to understand the app and they worked the way EcoWorthy claims. They are heavy, might want to have 2 people.

So far I have nothing but good things to say about "Echo-Worthy" and I really like my "six server rack batteries w rack" I also bought the battrery monitor, and I plan on buying another 6 by the end of the year before the tax credit goes away. There was a scratch on one of the parts as a result of the Fed X delivery guys dropping my box, and Echo Worthy stood right up to the plate offering to either send back a new part or give me a $45 credit. I took the money. :) I think they have a high quality product at the best prices, and they have top notch service available to answer my questions. Thank You Echo-Worthy.

so far the batteries have been great but the day is young as they say my inverter is the Eg4 6000xp and communication works just fine as of now running SOC settings reads everything i fully drained and fully charged all three and all works great as of this post
