These are solid batteries. They connect well with EG4 6000XP converters. You really can't beat the price to performance ratio with them. I've not done an official capacity test, but they seem to work fine and keep pace with the much more expensive EG4 batteries I already had. One big gripe, and it's one that has been addressed - I got an early batch of 4, and the positive/negative terminals are reversed to what you may expect. The EG4 batteries (and most other brands) are the other way around. I believe that they have upgraded the terminals and reversed the orientation since then. not an issue if you aren't mixing batteries, but it could be an issue if you already have an installation. No display, just LEDs but they are plenty. The batteries have bluetooth capability, so you can monitor them that way. Also, they support multiple common communication protocols. Like I said, I'm super satisfied with the life and price so far.

Easy to install and seem very well built. Been recycling daily for a month now and no problems. Contacted customer service and they replied quickly. Ap was easy to install and quickly hooked up.

I used 2 of these batteries to build a mobile solar generator. I am happy with the quality, size, and performance of these batteries.

The Eco-Worthy batteries are working great for us. The batteries came quickly and were well packaged, but they are heavy! We've got 5 of the batteries hooked up to a Sungold Solar 10K split phase inverter and powered by 6200 watts of rooftop solar. Most days the batteries are full by 1pm or so, then discharge overnight to around 50-60%. We're connected to the house circuit via a transfer switch and except for rare multiple cloudy days are able to power every circuit 24/7. Batteries appear to be high quality, all 5 stay within 1% of the charge state of the others. We've had no issues with any of them.

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)

Researched many server rack batteries before purchasing these. A little leary about China based batteries but they had a very large presence. Purchased 2 units and worked so good, I purchased 2 more for total of 4 48v 100am server rack batteries to support my EG4 6000xp Inverter. Battery was very well packaged (super heavy) and very easy to setup. Had WiFi problems on two units, contacted Eco-Worthy support via Amazon (Charlie) and via Solar DIY Forum (Bill Young). Bill was very familiar with the product and responded quickly. They replaced two units and all are working great now. Was able to charge all 4 batteries 100% and remotely manage all batteries through the EG4 App as well as the JBD App (very poor interface). FYI - Trying to connect with Eco-Worthy support via phone or email or even website is impossible so Solar DIY forum is best followed by site you purchased. They do honor their warranty and are responsible if you communicate through the correct channels.
