ECO-WORTHY 3584Wh 12V 280Ah LiFePO4 RV Battery w/Bluetooth & Low Temp Cutoff - Built-in 200A BMS - Deep Cycle for Camper, Trailer, Off-Grid, 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.

Tested battery with a multimeter after unboxing. Voltage was 13.14 vdc on all 4 280ah batteries. Connected all batteries in parallel for a 5000 watt pure sine wave Giandel inverter. Batteries were connected to inverter via 8 4 awg welding cables. 4 positive and 4 negative. I fully charged batteries with an ampivnt Solar controller and then proceeded to test the batteries. First I started with a 400 watt heater. Then I added a 300 watt ice maker. Dc voltage didnt drop. Next I added a 750 watt dehumidifier. Still the system was not even close to being pushed. Battery volt started at 13.79 and was currently at 13.75 dc volt under 1600 watt load. Lastly I added a 1500 watt magnavox heater and and 1800 watt waring pro dual burner hotplate. With ac watt draw at over 5000 watts the battery voltage only had dropped to 13.45 dc volts. These batteries are a must have and are cheaper than buying a big solar generator. I highly recommend to those who need backup power or plan on a diy solar system build. with this amount of performance these are of very high quality with superior performance under heavy electrical usage. If you upgrade to lifepo4 batteries make sure your charger or solar controller are lithium compatible and adjust settings accordingly.

good battery. It came one day before the estimated delivery date. 50% charge well packaged. I also bought a Timesub 40 amp charger for Lifepo4 Batteries that charged the Ecoworty up to full charge in less than 4 hrs. The bluetooth works great . I am going to buy another one. This handles my power needs for a whole week. Here in the Pacific Northwest Sunshine is rare this time of year. This Battery along with minimal solar input discharged to 40% in 9 days. LOVE IT !!!

It's been a few months since I purchased two of these batteries. They arrived without damage due to very good packaging on the seller's part. They shipped quickly and they arrived ahead of schedule. They have performed as advertised and to my expectations. The app is easy to use and was easy to set up. The only negative I have is that the BT radio in the batteries seem to be a bit weak. That could be in part due to the very robust construction of my particular RV. Sometimes I have to try two or three times to get one of the batteries to connect. Other than this minor issue, which is a small annoyance, these batteries have performed great. I would highly recommend these batteries to anyone, as I did to a friend a couple of months ago. He installed them in his RV and the batteries have performed flawlessly.

This has been a great battery so far. More than doubled the amount of amp hours I had with my fla batteries at half the weight. The only thing bad, I wish I had gotten the Bluetooth model. It charges well on my solar system or AC charging.

I rarely write reviews but I will for this battery. I have two of them wired in parallel connected to a Giandel 2200 inverter for about a month now. I charge them with two 200w solar panels, a Victron 100/30 controller, and a 30A wall charger for lithium batteries when we get days of cloudy weather. I monitor the batteries with the Overkill Solar app. The system is used primarily to run two chest freezers. The freezers cycle from 0W to 65W so the most draw I ever see is 130W. Without recharging, the batteries will run the freezers for 46 hours before they dip below 20% state of charge. With the right number of solar panels and good sunny days they could stay charged indefinitely. So these batteries are the best bang for the buck that I've found, and I like things that just work without fussing or having a huge learning curve. These just work with zero issues. I'm going to continue buying them as I expand my system.

The battery that I received measured nearly 0 V across the battery terminals, even after fully charging with an Eco-Worthy 20 A LiFePO4 charger. I contacted Exo-Worthy customer service and they responded the next day with some instructions for evaluating the battery, and upon completing the evaluation they determined that the battery was defective and immediately shipped a replacement free of charge. The replacement battery worked perfectly and has met all of my expectations. Eco-Worthy asked if I’d be willing to conduct a tear down of the original defective battery, to help determine the cause of the problem so that they could use the information to improve their product. I agreed, and upon opening the battery case and removing the cell pack I discovered that the BMS cable had been routed in a manner that resulted in it being pinched between a steel bracket and the side of the battery box, which ultimately cut one of the 5 wires. I reported the findings to Eco-Worthy and they immediately shipped me a new BMS cable, again free of charge, so that I had the opportunity to repair it if I would like to do so. I did and the battery now works flawlessly. The customer support team at Eco-Worthy was outstanding, and despite initial disappointment with the defective unit I would not hesitate to buy another Eco-Worthy product considering the phenomenal customer support that they demonstrated. Repairing the first battery also provided me the opportunity to evaluate the design and construction of the internal components, and I was very impressed with what I saw! The four battery cells were all secured together in a custom designed, powder coated steel cage, neatly secured together and protected with a dense foam product on all sides. The BMS was a JBD (Jiabaida) brand; a high quality, respected and well known BMS manufacturer. The BMS was securely mounted to the cage structure, complete with an aluminum heat sink and plenty of air space surrounding it. The BMS cable was a customer harness, wrapped in cable cloth and each wire was cut to match the distance to the corresponding cell terminal. Ring terminals were crimped to each wire end and heat shrink protected the connection. The 5 pin end of the harness at the BMS included a dab of sealant to ensure it remained connected. The cell connections were all secure, with the final positive and negative terminals in the series secured with a nut that included some sort of thread lock material. Lastly, the positive and negative wires were 6 gage silicone cable, and were routed in such a way to ensure that the positive and negative could never come into contact or abrade against each other to short the battery. All in all, the quality of the internal construction and the quality of the components used were very impressive. I’m very pleased that I purchased this Eco-Worthy battery.

Used one season so far, much better than the two 6vt batteries I had. Removing the two cleared some room and dropped some weight from my rig. App interface is great. I use the trailer factory charging system, gets it to 80%, then I plug is an aftermarket one made for these batteries to finish it to 100%. Usually charges from morning till I leave in the late afternoon and everything is 100%.
