The media could not be loaded. I purchased these ECO-WORTHY batteries for my family in Cuba, where having a stable power source is essential, and they have exceeded all our expectations. Each battery provides 2.56 kW of rated power and up to 5.12 kW of maximum output, and they can be connected up to 32P, making them perfect for building a strong, scalable, and future-ready energy system. One important detail is that I combined these batteries with the ECO-WORTHY inverter from the same brand, and together they work exceptionally well. The full compatibility between the battery and inverter ensures better performance, greater efficiency, and a much easier installation. The complete system runs smoothly, quietly, and reliably—ideal for households that need dependable energy every day. The build quality is excellent, the batteries hold voltage very well, and the real capacity matches the manufacturer’s specifications. My family has noticed a huge improvement: they now have a trustworthy power supply for their daily appliances, even during outages or fluctuations. I highly recommend these batteries to anyone looking for a durable, powerful, and reliable solution. And if you pair them with the ECO-WORTHY inverter, you get a complete system that is absolutely worth the investment. It truly makes a difference for families who need stable energy.

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.

Genuinely impressed by the value here! The batteries have all the bells and whistles you need. Some more expensive batteries have a status screen on them. But if you’ve got closed loop communication like these do, what the heck would be the value of a screen? They all arrived very well packaged and completely undamaged (sorry to my delivery guy, by the way). The rack is already 50% assembled. It literally takes like 5-10 minutes to screw the posts together. The bus bars are nice, but i kinda wish the holes for securing the wire for the inverter were farther away from the end of the bus to make strain relief and wire routing just a little bit cleaner. All the batteries are delivering the capacity they promised. I did contact Ecoworthy once with a question and they were surprisingly quick to respond and very helpful. I hate to say it because I really wish this stuff were manufactured in the US, but this kit is really, really hard to beat value-wise. It’s powering my entire 2000sf house and not breaking a sweat. It’s coupled with my EG4 18kpv inverter and closed loop communication is working perfectly.

I bought this ECO-WORTHY 48V LiFePO4 battery for my off-grid solar system, and overall I’m very satisfied with it. The first battery I received had two issues: the actual capacity tested slightly lower than expected, and I had trouble getting the CAN communication to work with my Victron Cerbo GX. I also noticed the cells were not perfectly balanced on arrival. I contacted ECO-WORTHY customer support, and they were very responsive. Charlie worked with me step by step, asked for test results and screenshots, and helped confirm the problem. They provided a prepaid FedEx return label, even though the drop-off location was far from me, and quickly issued a full refund once they received the battery. Their communication was clear and professional throughout. I ordered a replacement battery, and the new unit arrived in excellent condition. This one works perfectly — CAN communication with Victron detected instantly once I wired the cable correctly, and the BMS reports accurate voltage, temperature, and SOC. After charging to the top, the cells balanced normally, and performance has been strong so far. Overall, the product is good, the BMS features are strong, and the support team stands behind their warranty. The battery pairs well with Victron equipment once configured correctly. ECO-WORTHY handled my issue quickly and professionally, which makes me confident continuing to use their products. Would recommend.

The battery works perfectly with no problems. I would have liked it to be able to utilize the EG4 protocol as an easier workout for me as all my other solar batteries are EG4 protocol.

Best value for the money out there. I bought this and made a portable battery backup with a SunGold inverter and a power strip, similar to the one Will Prowse made on his YouTube channel. Very happy with this product. I will buy another when needed. I'd love to get a whole bank of them to back up my house, but that's a project for another time.

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. Update Nov 2025 .... Had what I don't consider a problem and EcoWorthy went way beyond what anyone should expect to make sure I was happy. I would give many more than just 5 stars if I could. Will be buying more in future. Update 12/3 I purchased a second battery and hooked it up, including communication wire. Seamless install and app picked up second battery first try.
