ECO-WORTHY 12V 280Ah LiFePO4 Lithium Battery, 6000+ Deep Cycles, FCC&UL Certificates, 3584Wh Energy, for Off-Grid, RV, Solar Power System, Home Backup, UPS, Marine

Several years ago, I purchased another brand of LiFePO4 battery (100AH) for more than I paid for this battery. It did not have anything like the SOC LEDs or Bluetooth monitoring. I had then replaced it with a different brand (200AH) which worked well, but also lacked the monitoring ability. Finally, I decided that I wanted to be able to monitor the battery as well as increase the capacity in our travel trailer to make sure we did not run short of power for boondocking. I use a CPAP machine. My wife uses an oxygen concentrator. The refrigerator is a compressor and not an absorption refrigerator. All of these use more power, so the increased capacity would be helpful. Turns out, I was right to make this choice for the Eco-Worthy 214AH battery. I was able to see that overnight would use about 50% of the capacity. The next day's driving would recharge it. I have a Renogy MPPT controller that can use vehicle power, solar power, or if shore power is available, the converter to charge the battery properly. This is one thing not mentioned that needs to be done if you are converting from lead-acid to LiFePO4 battery technology. The charge voltage and charge profile is different. The converter in most older trailers will only be able to work with lead-acid. The newer ones will be able to work with LiFePO4 batteries. If you are converting, you will need to check your breaker/fuse panel to ensure you have a suitable converter in it that can handle the change. The vehicle is another issue. Automotive charging systems are meant to charge lead-acid techology at 3.7v. I ran a dedicated line for charging from the truck's battery to the back and installed a 2-pole connector. This runs to the Renogy controller which can also do a DC to DC conversion to step up the voltage to the 4.5v needed to properly charge the LiFePO4 battery. If you don't have solar, Renogy also makes a DC to DC converter that can do that. There may be other brands. If that isn't done, you could find out as I did that you start with a fully charged battery and arrive with a significantly discharged battery as the higher voltage of the LiFePO4 battery will feed back to the tow vehicle and the alternator will be loafing, thinking that the higher output for charging isn't needed. As for size, length is shorter than the older 200AH battery. Width is the same, and height is a bit more. Weight is about the same as the older 200aH battery. That is to say it isn't light, but it is much less than the equivalent in lead-acid batteries would be and much less space is taken up by it. I installed it in a metal trailer tongue box that held the previous battery. In my opinion, this is a great value for the money. The capacity and features make it so.

Pues apenas llevo una semana con ella ya instalada y funciona bien , si es Bluetooth,llegó bien sin daños . Me gustó. Tuve que comprar un cargador aparte de la marca victron, que están en casi 4mil , para carga de alternador del carro. Esperemos dure mucho . De momento da buena impresión su uso .

My Semi Truck uses a lot of power when I’m sitting. Besides all of the regular electronics, I have a refrigerator and then a secondary freezer. Typically with four Group 31 batteries I need to start the generator every morning because the batteries are weak to start my truck engine. Installing two of these eco-worthy batteries along with a group 31 starting module can easily go two days plus with just sitting. Please remember. You get what you pay for. These batteries are definitely a nice option but if you know anything about. LifiPo4 you know that having matched cells is a crucial point. The cells in the two batteries I bought were not perfectly matched, but they were pretty close. but obviously that slight difference meant that they cut off early before getting to full charge and cut out early before getting fully depleted. It was only by a small percentage of the cycle but still notable. So if you’re not going to spend the big bucks to get perfectly matched set up. This is the way to go.

So far this 300AH battery has performed well. It’s been in continuous use since installing into a 2024 bumper pull RV. These new RVs have a 12 volt only refrigerator now. Turning the refrigerator off is not an option when living in the RV. A good battery is needed to make it thru the night, and this one can handle two or more days without charging it. I like the Bluetooth monitor app too, super easy to use. I am on the road all winter in this RV, with many days boondocking. It’s kept charged with a 400 watt solar system.

I wanted to share my experience asap, while the battery is still on sale. I received my Eco-Worthy 280AH battery exactly 1 week ago. It shipped very fast, was packaged well, and arrived undamaged. I have put it through a few cycles and monitored it's performance closely. It exceeds it's rated capacity, and performs as advertised. I watched quite a few video reviews of the battery before deciding on it. Eco-Worthy has exceptional build quality, with a metal cage protecting the cells and keeping them under light compression, to avoid swelling. There are more expensive batteries that do not have this build quality. Additionally, Eco-Worthy has the BMS mounted to the metal frame, isolated from the cells, which should allow for better thermal management. The metal bracing should protect the cells from vibration and keep them properly compressed. This will prevent any swelling during cycles and should increase the lifespan of the battery. The BMS was a key factor in my decision to buy the Eco-Worthy. My battery came with a JBD-DP04S007 200A BMS. This was important to me because JBD has a good reputation for quality, and I also knew that a JBD BMS should be compatible with other BMS monitoring software. In particular, I was looking for a battery who's JBD BMS was compatible with the Overkill Solar app. I can confirm that my battery & BMS are compatible with the Overkill Solar app. This is important for me because it allows me to monitor the performance & configuration of the battery in more precise detail than with the stock software. The factory BMS configuration appears to be well calibrated, so I saw no need to change any settings, and if you are using the Overkill Solar app I would advise you to leave the settings as they come from the factory. Probably the only suggestions for improvement I have for Eco-Worthy, would be to improve their application to show more details, and to have better compatibility with tablets. And also I would like for the BMS to be password protected. The Eco-Worthy app works well, it provides the basic functionality and information necessary to monitor your battery, but I prefer the Overkill Solar app. Overkill Solar performs better on my iPad Pro, it allows me to use it in landscape mode in full screen. And of course, on both my android phone and iPad, I can monitor the precise cell voltages in the Overkill Solar app, I can see when they are balancing, and I can also review all of the factory configuration BMS settings. After my initial full charge and allowing the battery a few hours to balance the cells, the cell balance delta has been very good. The cells in this battery appear to be well matched, they appear to be grade A as advertised, and perform well throughout the working voltage range. I will attach some screen shots to demonstrate this. I have been able to power all the appliances I was hoping to run with this battery, when paired with my 2000w Giandel inverter. Including my microwave, instant pot, induction stovetop burner, electric heater, etc.. I expect that this battery will perform reliably for many years. Eco-Worthy claims 6000 cycles / 15 years, and I expect that will be true. Eco-Worthy is delivering the best value battery here IMO, when you consider the build quality, quality cells, and capacity for the price. Their support was also responsive and helpful when I reached out to them with questions, they stand behind their product and are willing to work with customers whenever there is an issue. Since this is a review after only a week of testing, I will come back and update it if anything changes.
