Features
- [Bluetooth APP Monitoring] ECO-WORTHY 12V 280Ah Smart LiFePO4 Lithium Battery is built-in upgraded smart BMS, accessed Bluetooth 5.1 module, allows you to monitor the battery information in real time through ECO-WORTHY APP. You can read the battery voltage, current, battery capacity and other important information at any time. Bluetooth connection range: no more than 15 meters from the battery
- [Advanced Compression Fixture] Our lifepo4 battery feature a high-strength metal frame inside that provides enhanced battery protection, shock stability and controlled compression to prevent expansion, ensuring long-term durability
- [Low-Temperature Protection] This 12V lithium battery features a 200A BMS with multiple protections, including low-temperature protection. Charging stops below 19.4F (-7C) and resumes above 32F (0C), while discharging halts below -4F (-20C) to prevent damage, ensuring stability in harsh conditions
- [Flexible Expansion] The ECO-WORTHY 12V 280Ah lithium battery delivers 3584Wh of energy and supports up to 4 batteries in parallel (1120Ah at 12V), making it an excellent choice for RVs with long-lasting power.It also supports up to 4 batteries in series for 48V solar power systems, with a maximum system size of 8 batteries in total
- [Charger recommendation] This 12V 280Ah LiFePO4 battery takes 14 hours to charge with 12V 20A LiFePO4 battery charger, about 6 hours to charge with 600w solar panel, and 14 hours to charge with 20A DC generator
- [Shipping Reminder] In order to ensure the safety of merchandise transportation, your order may arrive in multiple packages at different times. If you receive part of your order first, please don't worry, the rest is on the way! Feel free to contact us with any questions
- Long-Term Storage & Troubleshooting: If the battery has been stored unused for a long time, connect it to a compatible charger to wake the BMS from protection mode.

First charge seemed slow but that might be the chargers fault. Very heavy at 61lbs each. So far, great batteries, I bought the 2 pack. Bluetooth connected and works fine!

We use these in our camper van and they really hold up and give us all the powere we need. Even when we don't go out for awhile they stay energized. We think they are a really great investment.

I have nothing to complain. They came in a good condition, everything I expect is working without any issues including charging/discharging, BMS, bluetooth in my series (2x12v) setup to charge my ecoflow. *** super happy they even credit back the price difference between this black friday/cyber Monday deal *** The customer support is super responsive

Size: 12.8V 280AH*2
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

Great product …and great customer service. I have 4 of these working for over 1 year. Set up as 24v. Cold and hot they work great…. Tons of power. Had an issue and they took care of me… I would highly recommend Ecoworthy…. Lithium batteries can be tricky and require some “knowledge” setting them up and taking care of them so do your research on chargers/etc. These were pretty plug and play with a few learning experiences on my end. Blue tooth is important …so get this model. The low temp shutoff is 19’ which is nice for me. They work great all the way Down to below 0 and charge above 32…. You will need a lithium battery charger(or solar) to get them charged to 100% and 280ah requires some time so be patient l. I have a Victron charger 25amp and it took 8-10 hours for each battery. I have heard you should discharge and fully recharge them a few times before linking them up in series or parallel.

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.
