ECO-WORTHY EnergyRock 12V 280Ah Metal Case LiFePO4 Lithium Battery

We are a camping family who is building our own campervan and cargo trailer conversions. As we find parts and components, I will write reviews to hopefully inform others who are either on this journey or thinking about it, giving them a good source of information to help with their choices. In the campervan, we already have shore power to an inverter/converter that provides 120V for the portable AC, battery bricks/chargers, fans, and coffee machine, and supplies power to 12V plugs and lights throughout. When building this, I wanted to be sure we made room for solar charging and a battery. We mostly camp at campgrounds or state parks with electric hookups, so I imagine we will boondock less than 15% of the time. The reason we went with such a high-capacity battery was two-fold. The first part was that, if you read online, everyone has an opinion on what you need based on what they need, which makes it sound like you need 55kWh per day to boondock while solo camping, fueling battery anxiety. The other reason is that while we don't boondock much, when you need power and don't have a plug but want coffee or to run the AC for a little bit, I wanted to be sure we have it available. Size: This is a larger battery that weighs around 60lbs. Compared to car batteries, the size-to-weight ratio is really nice. It fits perfectly into the little nook I inadvertently made for it in the bed frame, so for me, it could not be a better shape. Function: Having the extra capacity is actually pretty great. There are times when I need to work on something farther from a plug, and I plug in the shop vac, a table saw, or some other power-hungry device, and it handles it like a dream. It is like those commercials where people are out in a field with their truck and decide to have a party with string lights, so they plug into their car, except this will power a ton of stuff for a good amount of time. I haven't done a full-to-empty test on this yet, but I was able to do two hours of work in the van with the portable AC running and the lights on inside, and it dropped to 30%. This is a 12,000 BTU portable AC for reference. Also, the Bluetooth BMS and companion app are very nice. The range I can check on the battery has been around 12 feet, and the data from the battery matches what the shunt is showing. I also love the post location being on the side, so I don't have to worry about accidentally bridging them and causing an issue. The metal case is also great. I don't know if it is a placebo effect, but it makes the battery feel a lot sturdier and like it will last a long time. For my use case, this is a great battery. It powers everything I need it to, lasts a long time, and fits well in my van setup. If I need another battery elsewhere, I will definitely consider getting another one just like it.

I bought this ECO-WORTHY 12.8V 280Ah LiFePO4 battery to upgrade my RV from a single 110Ah AGM battery to a much larger lithium setup. I ended up buying two of these, giving me 560Ah total. That is a huge jump from my old AGM setup, especially since a 110Ah AGM really only gives you around 55Ah of practical usable capacity if you are trying not to abuse it. These batteries are not small. Each one is noticeably larger than my old Group 31M AGM battery, with the listed dimensions around 16.54" x 8.64" x 9.65". The funny part is that even though this has more than 2.5x the rated capacity of my old AGM and uses a metal case, the weight is about the same. This battery is listed around 68.5 lb, and my old AGM was about 67.2 lb. So I gained a massive amount of usable capacity without really adding weight per battery. The specs are strong for the price. Each battery is rated at 12.8V, 280Ah, and 3584Wh, with a 200A max continuous charge/discharge current. The case is metal, which is exactly what I wanted, and it has front terminals that made my RV battery bay layout much cleaner. I also really like the built-in on/off switch. That is a very nice feature when wiring, storing, working on the system, or just wanting a simple way to isolate the battery. Bluetooth monitoring was another major reason I chose this battery. I wanted to be able to check battery state, voltage, current, and general status without guessing. The Bluetooth feature is very useful when you have multiple batteries and are trying to keep an eye on what the system is doing. I also wanted low-temperature protection because I do camp in cold weather. I recently got back from a snowy RV trip where it dropped to about 20°F at night, and I had no issues with these batteries. The box lists a 20°F / -7°C cut-off, which was one of the reasons I was comfortable using them in my setup. Obviously, lithium batteries still need to be treated properly in freezing conditions, but having low-temp protection built in is important. A few notes from my installation and use: • 12.8V 280Ah LiFePO4 battery • 3584Wh rated capacity • Metal case version • Built-in Bluetooth monitoring • Built-in on/off switch • Front terminals are very convenient • Listed 200A continuous charge/discharge current • Much larger than my old Group 31M AGM battery • About the same weight as my old AGM despite far more capacity • Low-temperature protection was important for my RV use • Worked well during a snowy camping trip around 20°F • Good fit for RV, solar, off-grid, and house battery upgrades If you are researching LiFePO4 batteries, Will Prowse is worth looking up. He tears down lithium batteries and does detailed reviews, and this is one of the models he recommends, especially for people who want Bluetooth monitoring. Even ignoring that, this is one of the better priced and better rated batteries I found in this capacity range. One buying note: make sure you choose the exact version you want. There are ABS/plastic case and metal case versions, and I specifically wanted the metal case. I originally ordered the ABS version by mistake, but ECO-WORTHY customer service was great at cancelling my Amazon order and getting me on track with the metal version. I like that the metal case version has an on/off switch, and front terminals are exactly what I wanted for my RV battery compartment. Overall, I am extremely happy with these. Going from one AGM battery to two of these is a massive upgrade. More usable capacity, similar weight per battery, Bluetooth monitoring, front terminals, an on/off switch, and freeze protection made this a great match for my RV.

Great battery for use with a sump pump! My 1/2 HP sump pump draws about 500 watts, and based on calculations - the battery think's it'll last about 5 hours of continuous use - and 12+ hours of use every 45 seconds. This should easily outlast the basement watchdog it replaced in terms of actual run time - and a big plus - it's powering my full power sump - not some 12v mini pump. (I paired this with a 2500 watt Inverter/charger.) One of the big considerations for me was the 200 Amp running load capacity - Sump pumps can draw a bunch of power when they start up - This battery has ample capacity in that area, it may well be overkill, but that overkill translates to peace of mind. Other pros for me for this battery were the metal box, the power button was useful for connecting without causing a spark, built in handles and something I didn't consider when buying it but the top is completely flat, making it possible to stack two of these if desired, or in my case I set my inverter on top of it. The bluetooth connection is nice for checking charge status, load and remaining running time at the current load. It's nice to be able to monitor the battery separate from the inverter. Overall this plus my inverter have replaced the old basement watchdog system and I couldn't be happier.

Paired with victron charge controller, 3000 watt inverter, and 300 watt solar system at my off-grid get away in Tahoe. Have put it to the test on a few 4-day weekends...very impressive. Excellent performance and runtime. It ran everything. Going to add a second battery and up the solar to 1000W next week and swap the propane fridge out with a 12V

I love to see a company go the extra mile to ensure the battery arrives in excellent condition (shipping companies these days are horrible). Some have complained about shipping damage and damaged terminals. I was a little worried about this. It looks like they have corrected some of these issues with outstanding packaging. Mine arrived in perfect condition. Attached pics of how they are protecting the terminals with a smart upgrade of high impact foam. The battery turned on and tested @ 13.18V and the Bluetooth app connected to it with no problem. I didn’t need to sign into the app to get all the battery stats. So far I am seriously impressed, will see how it functions in a RV environment, will do an update on that. I did remove the lid and the battery is built very well with clean cabling. Can’t say enough about the quality. Only a few things I would like to see 1. Water tight seal on the lid. 2. IP certification. For the money I paid this is a home run! Buy it!!!!!! Updated: pic of charging the battery @ 60amps, love the metal case.

Great investment so far. Takes the place of 2 deep cell batteries at the weight of 1. Easy to hook up. Battery keeps my rv fridge going all week with just a 100-amp solar panel attached. The 2 deep cell batteries did not. Light weight but did need to make some modifications to make it fit. It is a touch wider than regular batteries. Overall, very satisfied.

Bought this to run our new 12V AC in our 5th wheel RV bedroom since our Bluetti AC300 was not able to operate it and would error out for low voltage. Only have had it a week but it works fantastic. The true test is the 100 degree heat that has not happened yet. The on/off button is a great feature to have and I purchased the metal case as added protection. Very easy to set up and connect via bluetooth to your phone. I also purchased a 50 A LifePO4 charger because the Bluetti will charge but at a very small rate and the 50 A charger will charge the battery efficiently and quicker. So far we are very happy with the battery and may buy another one if we get another 12V AC unit for the living room/kitchen area.

I think it is a good product. Had to return because it weighs so much.

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 .

Excelente Bateria de buena calidad y el embalaje Excelente a pesar de su peso !
