Great battery for the price! Way better value than the name brands, it is well made, has a safety fire arrestor, and was shipped quickly (by truck). Overall, I am happy with this purchase and I will add another as I expand my home battery backup.

I have not tested the battery itself yet but wanted to write a quick review regarding the customer service I experienced with Eco-worthy. I had a minor shipping issue that was of no fault of Eco-worthy. I contacted Eco-worthy regarding the issue and they were very responsive and corrected the issue ASAP. I would not hesitate to order such a large purchase from Eco-worthy again. They have very good customer service. When I test and use the battery, I will leave a review. But the batteries come in very well built wooden crates and look perfectly fine. The construction of the batteries look and feel very high quality.

Works well with my shed. A few of these could totally power a house. Works well with an EG4 chargeverter.

Very nice battery, huge capacity and very easy to set up. The app is basic and trash and I can't seem to get the Wi-fi working on mine but hat is probably a skill issue on my part. FYI, this battery is very heavy. I can recommend this one easily.

Excellent communication. Battery arrived on time with no damage. The battery functions as advertised with Ah slightly higher than advertised. I will be buying more. I like the fact that it doesn’t take up a lot of space. Pretty easy to get set up and running.

I cant find a review related to it - but apparently I misclicked and applied a 1 star review to this rather than a separate product. The eco-worthy team went above and beyond, I received my package as expected - and they have followed up consistently to ensure I was happy.

This appears to be a quality product at a reasonable price. Everything is working well so far. I have not run a capacity test but the displayed capacity is slightly greater than the listing so that is reassuring. It comes with 2 gauge quick connect battery cables. The packaging and delivery were excellent for such a large item. It is extremely heavy so please be careful and get help when moving. The wheels and stands are quite convenient. I carefully followed the instructions, which warn about the tipping risk and how to properly move the battery. I have not had any issues but their customer service has been proactive and provided useful information regarding the delivery.
