ECO-WORTHY 48V 280Ah (4 Packs) LiFePO4 Lithium Battery with Bluetooth, Low-Temp Protection, 6000+ Deep Cycles, 14.34kWh Energy, for RV, Off-Grid, Solar Power System, Home Backup, Back up Power, Marine

These batteries are great. I dont think they can be beat for the price. We hace 2 and ran stuff for 4 days straight no problem no recharge straight battery. I would recomnend these if serious about bang for the buck and good quality for sure, happy customer.

So far so good on 4 of these 280 AH batteries in parallel. They are 67 pounds each, far different from most Lithium batteries. The nice thing is they can be wired in series too. The story is still being told, but so far I'm satisfied.

Have had them working on my camper now for over a month got 4 and their 5000w hybrid inverter on my camper. They all work well together.

Working good 👍

Slower drain then my supposedly slow drain deep cycle AGM set. Weight about 1/3 of gel matt (AGM) but not suitable for outdoor use due to a VERY limited temperature range. Charges fast with a smart charger. Not used much since i is power backup and not suitable for use in a greenhouse or I would have 6 lined up and regular use. Used indoors with an expensive inverter. Snohomish County has a very outdated power grid. Size is HUGE. I wish it were shorter and fatter, uses an entire 24" by 24" shelf.

Is all I needed for this year

Well, I'm going to keep this as short as possible. I bought the 2 piece 280ah batteries here on Amazon. It was a great price for this capacity battery for my RV. One battery arrived in perfect condition, and the other arrived with no labels at all. I called Eco-worth and expressed my concern with receiving a battery with no labels. They literally told me to "try them and see how they do." Seriously?!!! What if my RV burns down because of mismatched batteries? They offered to do an exchange, but I had to ship their battery back on my dime, and provide proof of shipment before they would ship me a replacement. Needless to say, I'm processing a return through Amazon to send both batteries back. I really wanted these to work for me, but I'm not ok with an unlabeled battery. If this is an indication of their quality control, I'm happy to pay more for a better product.

I am a real buyer of these batteries. I use them with solar panels, inverter and power a portion on my house with them. I had T-105 lead acid battery bank. Welcome to the Future !!! The customer service is excellent if you have questions. Not only do I recommend these batteries and this company, I just purchased 2 more of them for a total of 4...
