ECO-WORTHY12V 280AH LiFePO4 Lithium Battery with Bluetooth, Low Temp Protection, Built-in 200A BMS, 3584Wh Energy. Perfect for, RV, Solar Off-Grid Power SystemCamper and Travel Trailer, Group 8D

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.

Beast of a battery! Unclear on over amperage cutoff, but great reviews. Clean build and easy to install. Size was slightly larger than I expected, but they did give measurements on the page, lol... Not sure about low temperature cut off yet.

The battery is 4 inches shorter than other brands and includes Bluetooth, which they don't offer. At a sale price of $399, it's a great deal. I've owned three large-capacity batteries before, and this one stands out as a solid option.

This battery is a five star battery, charged up and starting working, no problem. The bluetooth app is amazing and better than many shunts. I am impressed beyond words.

I do not normally rate or leave feedback but this this Battery is GREAT ! !FIVE STARSI Am Impressed

they are just what they say they are. great capacity test and $ for $ very hard to beat . asy setup 12 or 24 v strings

I think eco worthy did a bait and switch on their customers, and their current batteries don't have bluetooth anymore. Sure, on youtube you can see people saying how great the bluetooth is but just try getting it to work. I bought two batteries off of amazon, and two more from another website, and none of them connect to the eco worthy app. I also tried the app on my phone, and a brand new tablet I bought with the same results. I'm a little disappointed in that because I wanted to see how well the cells were balanced. If anyone else leaves a review after me, please do me a favor and try to connect the eco worthy app to your batteries to see if it works.Edit: I did get the batteries to charge past 60%, which was a problem some people were complaining about. I charged each battery with an eco worthy charger for 6 hours, then let them rest for 8 hours. The voltage settled at 13.30V, which is around 60% charged, according to the booklet. I then charged it again, and the second time the voltage spiked to 14.5V, and the charger went into standby mode. Five hours later I checked the battery voltage, and it had settled to 13.39V, indicating that it was above 90% charged.

Fast delivery, packaged very well. Arrived in perfect condition. 30%charge out of the box.
