ECO-WORTHY 12V 280AH LiFePO4 Lithium Battery with Bluetooth, Low Temp Protection, Bulit-in 250A BMS, 3584Wh Energy. Perfect for Off-Grid, RV, Solar Power System, Trolling Motor

I made the right choice with this battery; it exceeded my expectations. My battery is based on the SP04S034L4S200A BMS from JBD, firmware 7.0, which is a newer model. Bluetooth works as expected, though the range is limited to 10 meters. The manufacturer’s app functions well, but I couldn’t create a profile because my email contains an underscore, which the app incorrectly flags as an invalid character.Communication with the manufacturer has been great and supportive. The battery capacity is as advertised. A notable feature is the ability to check and change BMS settings via Bluetooth. From the factory, balancing was limited to charging only, which needed adjustment, as did the low voltage cutoff (set at 2.2V) and high voltage cutoff (set at 3.75V). The low-temperature charging was set at -7°C, which should be 0°C. The short-circuit limit is 2000A, which should never be tested.The BMS has three temperature sensors: one at the BMS and two at the cells, all working as expected. Bluetooth is embedded in the BMS and connects easily within a short range. Note that there is no security on the Bluetooth connection, so it shouldn’t broadcast over a wide area.The battery contains four prism cells with a compression structure, and the cells are easy to balance with the supplied BMS.Did I make the right decision buying this battery? Yes. Would I buy a battery without Bluetooth now? Probably not. Would I buy this battery again? Definitely yes.Thanks to Eco-worthy for the communication and providing the right product.

I received the Eco Worthy 280Ah battery ahead of the predicted delivery estimate, which was great! It was charged to a minimal SOC as advertised and the associated Eco Worthy 20A battery charger brought the battery up 100% SOC within the estimated time frame. I easily connected a 2000W inverter to the battery and it worked flawlessly.During an extended but planned power outage in our neighborhood, I used the battery/inverter combo for 2 hours to power some lamps, a large screen TV, a cable modem/Wi-Fi router, a coffee maker and computer equipment and the battery SOC afterwards was approximately 80%. I was very pleased considering the wattage consumed by the coffee maker.I will use this battery as a power back up in my house for critical appliances and for car/van camping trips.

Works perfectly! I had considered changing from lead acid for some time but the cost seemed to be a bit much. My RV dealer wanted $1400+ for a 100ah battery. I got them to give me the specs for the battery they were quoting and I done some research and found this battery with very similar specs which is rated 280ah for just under $600. WOW! that is a no brainer. I wasn't sure if my RV (2022 Jayco Four Points) was compatible. Fortunately it was. I just had to move a DIP switch and it will fully charge the battery to 100% capacity. The battery has bluetooth connectivity so you can monitor its capacity which is a great feature.I was having issues with using the battery to extend the pushouts and operate the self leveling jacks as it would sometime just quit due to low voltage so I assumes that maybe the batteries had discharged an would not fully recharge so I opted to make the change. I'm very happy I did No issues operating any of the battery connected devices. I would recommend this battery to anyone wishing to upgrade to LiOnbatteries.

I bought 2 of the 280ah ones. I like them, the range of the Bluetooth app is great, about the same distance as a BT speaker would go from your phone. The app tells you everything you need to know about the state of charge in voltage, percentage of charge and current draw, time remaining at current load draw, amp charging, amp discharging. Individual cell voltage also.

Just purchased a 4th eco worthy 280ah battery. This version was the new bluetooth battery. I got to say I love how clean and clear the eco worthy bluetooth app is. These batteries can store so much power it's just fantastic for the price. It honestly surpasses renogy and many other competitors batteries. I have not had any issues with these and it's been over a year or so. Eco worthy has become my favorite place for my solar setups. Thank you eco worthy for having one of the best customers services out there. 5 star review for eco worthy!

Good prive per the size and cuality

Bought 8 to make two 48V battery banks. Doing well so far, 2 did not have Bluetooth unfortunately. I have been using them for several months.

Easy to setup, working well 6 months in.
