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.

Amazing value for the money

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.

So far so good ,battery shipped faster than expected. Just wish it were self heating. No complaints for the price

I have installed 3 of these hooked to an EG4 flexboss 18 inverter. They have been running for about 1 week as of this review. They are communicating well with the inverter. I also have Eg4 wall mount indoor batteries connected to a second inverter. I would say that these EcoWorthy batteries are a good value, but lack a few features that the Eg4 batteries have. These price is appropriately low to make up for it. I like the wheels that can be locked in place. This makes them easier to get into place. (Careful not to tip them over) the screen is nice. Things I wish they had: Ul listing Built in breaker Cover for the wire terminal compartment L brackets to secure them to a wall The case is durable enough, though the eg4 batteries seem to have an even tougher case. I'm overall happy with the purchase. If these "missing" features are Okay with you, then these are a good value. I have rack batteries from them that are good and have breakers. It's a trde off. Much prefer these as far as cleaner install. Shipping was quick and te the seller was good about alerting me to shipment updates. I have purchased multiple different items from ecoworthy through Amazon and Ebay and have always had a good experience with their communication and effort. I would give this product 4.5 stars if it had a breaker, and 5 if all the things on my list where updated.
