  • Very good 48V batteries, Bluetooth, solid build, great price.
Size: 51.2V100AH*4
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. ... show more

  • Reasonably priced, good functionality, good build quality.
Size: 51.2V100AH
I used 2 of these batteries to build a mobile solar generator. I am happy with the quality, size, and performance of these batteries.

  • Great 48v rackmount battery - 52.6 nominal and working fine.
Size: 51.2V100AH
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. ... show more

  • Great Value (performance/price) compared to any other rack mount battery
Size: 51.2V100AH
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. ... show more

  • Good battery

I would give it 5 stars but I just haven't used them long enough. They produce what the specs are saying

  • Great batteries, good price
Size: 51.2V100AH
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. ... show more

  • Awesome upgrade
Size: 51.2V100AH*2
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... ... show more

  • Working great so far.
Size: 51.2V100AH*6
Batteries are working fine. The rack that it came with had no instructions and their online instructional video is useless. Make sure to pay attention if you’re buying their rack how the pieces go together. Other than that time will tell how good these batteries perform and last. Also you will need a second pair of hands these batteries are heavy, like any other 48V rackmount. I’ll prob be buying another 6 in the near future. The inverter had no issues communicating with them. ... show more
