ECO-WORTHY EnergyRock 12V 280Ah 4 Pack LiFePO4 Lithium Battery Metal Case | with Bluetooth, Low-Temp Protection, Built in 200A BMS, 3584Wh Max, Off-Grid Solar, RV, Camper, Travel Trailer, Home Use

These are awesome! I’m so glad I purchased them. They charge quite well and are not as heavy as regular batteries. I love the Bluetooth connectivity and the app is great to have. You can control everything by the app. Definitely worth the price. I only use batteries and I have no electric bill to pay. They have amazing quality and I recommend them to anyone!!

I bought 8 of these to replace an aging off grid Flooded PB array. Cost was comparable to PB and the performance is far better with less maintenance. Using an old android phone (EasyDesk) and WiFi, I am able to remotely monitor the battery individual status via the included internal Bluetooth BMS.

I have bought 12 of these batteries so far. All are working just fine. Had some technical issues with the newest batteries that included blue tooth monitoring. It took about a week of correspondence with the company to resolve some minor issue with recharging and having the blue tooth saying the batteries were fully charged Some technical person named Dante helped me through resolving the miss steps. The quality of his service and keep checking back to see things were getting resolved deserves a A++ grade I will continue to buy and promote their products because of his efforts high five for helping me you are the best!

Running 8 of these in a 24v system. Bluetooth works really well, has a substantial range. No issues with any of the so far.

Still have a problem every now and then with the Bluetooth connection.

I bought four of these for a 48V setup, and I regret it. The biggest problem is communication: battery monitoring is only through Bluetooth, the app is slow, it often fails to connect, and the readings are not always accurate. There is also no proper inverter communication. If your inverter uses CAN or RS485, these batteries do not connect, so the inverter cannot display accurate battery status or charge level. The other major issue is balancing. Even after charging them fully before wiring them together, the batteries do not stay in sync. One battery consistently ends up much lower than the others, sometimes by around 20%. I even bought an extra battery equalizer, and it still did not solve the problem. The price may look attractive, but the poor communication options and balancing issues make this a frustrating product for a multi-battery setup. On top of that, the seller has been slow and difficult when it comes to replacement or support. I would spend a little more and go with a better brand.

Simply amazing, wish I would have bought these batteries in the beginning instead of the 100 amphr batteries from Haya. Last a long long time, connect to your phone blue tooth so you can monitor battery capacity and charging status. 4 pack a great buy, will purchase more for future off grid solar projects.

I got them on sail and now have two full sets (8 batteries in all). They "act" a little different than my other LIFE batteries, that is the voltage goes down a so you have a better idea on actual life left. My original set when it drops .2 volts, almost 50% of battery life is used, these are more like .5 volts giving more granularity.
