The media could not be loaded. I recently purchased 2 of the 280ah batteries to install in my fifth wheel. Had outstanding customer service from Oliver with every question answered. Received the batteries in couple of days. Great packaging and the batteries were in perfect condition. Topped them off with Eco Worthy 20amp charger and decided to do a capacity test. So far so good they seem to be performing very well. When doing a capacity test of a battery this size it takes days. I can update the post after both are done and let everyone know if they reach the rated AH capacity. For the price they are a excellent value and highly recommend them. Update: Both batteries hit there rated capacity with no problems! Still going strong after 26 hours with a 11amp draw. Super happy with my purchase. ... show more

    • Bargain product as advertised, BMS in system operation is another........
Size: 12V 280Ah 2Pack
This pair of 280AH LiFePo4 battery works great, if my meter is any good, it registered 290AH. Like other 12v LiFePo4 batteries, they all list 14.6V as charging voltage. They may work well in standalone charger with 14.4v for boost, float and equalization voltage, those voltages are not for off grid system that are active 24/7. The BMS in this battery and one of my other brand battery will disconnect the battery from the system momentarily when the charge controller voltage reaches 14.2v, then reconnects to see if the voltage is below 14.2v and stays on if it is, repeating this process continuously until something breaks or break the cycle. This is fine in a standalone charge system, but in the off grid system charge controller will output overvoltage when the battery disconnects, causing the power inverter to shut power to your appliances and power back on when the battery reconnects, like flipping the power switch on/off to all your appliances every few seconds continuous until the solar power output is below the appliances power load. Power spiking to your appliances is harming and eventually burn them out. Fortunately my Renogy 100A charge controller has a user define setting for battery type, which allows me to set the voltages to 14.1v just below the threshold for the BMS to disconnect the battery, avoiding power spiking in my 24/7 off grid system. The 14.1v settings is just my trial and error setting to get the around the BMS overvoltage protection issue, I wish ECO-Worthy tells us what the user define boost/float/equalization voltage setting should be for off grid system running 24/7 and still get the most storage capacity from the battery. My old green label battery brand starts with letter J works with standard 12v LiFePo4 battery setting without power spiking in my fully charged (14.4v) off grid system running 24/7 for a year without any issues, but they have been awfully quiet for me to make any further upgrade investment ... show more

    • Good value.

I have had the batteries for only a couple of weeks. They suit my requirements so I gave them a five star rating. Hopefully they last as long as they say they well (longevity).

    • Not had long enough to give 5 stars
Size: 12V 280Ah 2Pack
Bought and installed 4 of these for my 48 volt battery bank . These replaced 4 premium AGM batteries which ( incredibly) still worked reliably after 11 years on my small electric powered sailboat. I felt The AGM still worked, but were 165 lbs. each and since LIPO tech has gotten to be lot less expensive , I bought these. I wanted Lithium tech 12 years ago but at that time you either had to build your own battery or pay $10K to $20Kfor lithium ion 225AH/48 volt. I don't think LIPO tech was even sold back then. I was able to install them without lifting help. They weigh less than half of my LIFELINE 8D batteries and were almost an exact drop in replacement. They are also less expensive than premium AGM. I hope they continue to work as well as they do now. ... show more

The media could not be loaded. Says it can last 6000 cycles. If I get half of that I will be happy. Not 100 percent sure what state of charge they recommend charging to. The attached picture with the specification guide and two post screws are all you get in the box. Have these connected in parallel for 12v. Tested up to almost 700 amps, voltage dropped to 11.9 during 20 second test, but recovered to 13 afterwards. ... show more

Shipping estimate is not accurate. But realize these will need to be shipped to you by ground only as they are "lithium" batteries. I have 4 in series and get all ... And more of 14.3kWh from these. Many LiFePo4 batteries have YouTube reviews I have not seen one for these. I may get one to do a cycle review or wait until I take my system down again because I think these will prove to be quality batteries at reasonable price. ... show more

    • So much better than AGM!
Size: 12V 280Ah 2Pack
Replaced eight 220ah 6v lifetime AGM batteries at 1760ah total with two Eco-Worthy 280ah 12.8 v LifePo4. Wish I had done it sooner. I am amazed at how long the 560ah last compared to my 5 year old AGM’s. Supports my family of 5 from sun down until sun up while aboard our sailboat. We run tv’s, fans, coffee maker, ice machine, water pumps, avionics, radios, refrigeration, water heater, lighting, as well as charge our phones and laptop and have never dipped below 30% state of charge by the time the sun was up and solar was recharging. I’m blown away! I’m contemplating adding two more for a total of 1120ah to run the marine AC and heat. A few positives over the old AGM would be significantly lighter in weight, fast charging capability, and no memory to shorten the life. NOTE: these batteries are slightly wider and twice as long than the AGM’s I replaced. Where 4 AGM’s used to fit only two of these Eco-Worthy will fit with a few inches length wise to spare. ... show more
