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.

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

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, 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.

Why did you pick this product vs others?: I purchased two batteries. I received one working battery. I am still trying to get the other battery so that I am made full. It’s been over a month now and I purchased these batteries because I live in a camper that needs these batteries in order to function. It provides power to a 5000 W inverter. I have been unsuccessful receiving a refund or the product that I ordered which is two functioning Batteries. Buyer beware!
