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

Installed 4 280ah batteries into my 27 ft camp trailer. Running 1200 watts of solar and a 3000 watt victron inverter charger. 12v. In las vegas I'm recovering enough solar to run both my refrigerators and basic electronics without issue. I installed a easy start on the ac, the ac uses 1400 watts to run so without shore power or a generator I can only run it for 3 to 4 hours per day. This is my first system I have used and installed. I have no experience to compare or skills to accurately test these batteries, they have ran extremely well and seem to charge and discharge as listed. Purchased in nov of 2024. 8 months of usage. Great product.

so far, both batteries have handled a heavy load well; only time will tell how they do in the long run. charging these 2 with 520 watts of solar panels.

Muchas gracias

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.

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 Snohomish County has a very outdated power grid.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.

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.

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.
