These batteries arrived undamaged, they were well packed. They had about 30% charge on arrival. My free rack could have been packaged or handled a little better but arrived undamaged, some of threaded inserts had too much paint in the threads and it was difficult to thread the bolts in at first. I ended up getting my handy torch to melt off the paint in the threads in order to put the rack together. I ordered a charger (different brand) and I was able to slowly charge all 6 up too 4 days. Now I'm just awaiting wires to connect my inverter and sub panel. Kind of bummed about finding out that I received an older version, and not the latest available. Seams like the same V1's and V2's could be listed separately for a discount, but I am happy that this company is constantly improving and listening to the customers request to improve their products. Keep up the good work. Hopefully when I order my next set of batteries it will be even better. Oh it would be nice if the rack had buss bars and a door for protection, I'm going to make one out of 1/4 plastic and some strong magnets for a protective cover.

LiFePO4 12V 280Ah Lithium Iron Phosphate Battery With Bluetooth

Seems like a decent inverter (so I am giving it five stars), but the cooling fan comes on and off way too often. I am only running 15-20 watt loads and this seems totally unnecessary with such a light work load. With such an aggressive fan, this unit should never have problems with heat. My minor gripe is that this fan is way too noisy. I have to wonder if there is a problem with the temperature sensing circuitry controlling the fan. Time will tell.

I've used this battery for my small trolling motor one time. It worked perfectly and ran longer than I thought it would. So far so good!

My Eco-Worthy solar panel array is performing very well, and I will be ordering more soon!!! Thanks!!!

Great products and great company to do business with.

I purchased the 280Ah Lithium battery to test a small solar energy system. It has run a Renogy 3000W pure sinewave inverter in a test by running a Dishwasher pulling 1472W ac, And a Washing Machine pulling 683W ac. The Ecoworthy sustained 74A to 214A peak while both appliances ran. After both completed their cycle the Ecoworthy was down to about 70% capacity. I am impressed. The battery delivers the current needed for tough applications. We'll done!

Great product at a low price.

LiFePO4 12V 100Ah Lithium Iron Phosphate Battery With Low Temperature Protection

Battery arrived as promised and saved my vacation at Lake Guntersville

This battery has been one of the best upgrades on my RV. Instantly I know my battery strength and how long I can run my inverter and 110 appliances. Bluetooth monitoring is a must, since lithium maintains voltage until it shuts off, unlike regular batteries that drop voltage as they are used. Rv battery monitoring lights do not work with lithium batteries. Very happy with the 150ah.

I had the wife's band use my Ecoflow Delta 3 Pro for 3 hrs. The battery went from 91% to 81%. I can wait for an outdoor concert this summer

Nice rack said the wife! Honestly, the hardest part was finding the initial documentation that is now posted on the EW site. There are You Tube videos as well. This is a nice rack for the money. No buss bars, doors, or anything else other than heavy duty casters that are a must have. Please note you are best served by having a helper assist you to load the batteries. This rack fits the EW 3U batteries in both V1 (handles attached) as well as the V2(1.1) handles removed for shipment and installed when you open the box. The point is that BOTH EW batteries fit perfectly and the holes lined up to secure with the included bolts, etc. In my opinion the build quality was very good. Just make sure you tighten all screws, bolts, and attach ALL parts for stability. Pull one battery out at a time for safety reasons and route cables carefully should you need to change anything. NO compensation or discounts were offered for this review

After many years of using FLD and AGM (and still do), I made the plunge into LiFePO4 server rack batteries. I don't have a YouTube channel since I work and don't have the time to make videos so the batteries shown in my review were purchased without compensation of any kind. The two lower ones in the photo are the V1 and my research indicating shipping damage was the driver to update to V2 with removal handles (secured by four small screws that are recessed). V2 are the upper three units in a rack. After testing over two months in parallel running large resistive loads, I can tell you these have held a decent balance. The RS485 communications between the battery and inverter has worked decently and these batteries do have an application that is on their site. The application is basic to validate DIP switch settings, voltage charge / discharge settings, etc. The BMS on V1/V2 versions is showing the same JBD48100000 with battery over-voltage at 57.6/3.6 per cell and a release of 54.4/3.4. Basically the application looks to be setup to give the beginner a method to charge without too much worry. I believe the application is locked down and would have to have the passwords to make changes, but in many ways a beginner should probably learn before changing anything. The temp sensors work and display in both C and F temps. The calls are laser welded, so having dependable hardware is a must. The blue tooth range is very short in my opinion but the cards are inside of a faraday cage so there you go. My batteries are setup for RS-485 Pylon to a EG4 inverter but there are a number of other RS485 and CAN options for major manufacturers too. I plan to call customer service and/or email them to inquire on firmware versions or better monitoring / configuration applications. I believe EW is now including a RS485 to USB adapter which is nice to have for sure. I use an external Victron Energy 300A shunt and when you compare the individual SOC% against the shunt, so far not much SOC drift of any consequence. Also, IF you get more than one battery you will have to set one as a master. Powering down the master, will power ALL batteries down in one shot! I did NOT read this in any documentation, so be aware! Being an older guy, make darn sure you have help to move the 100# /45kg monsters! I am thinking of getting a lift system since back injury is NOT worth it! So do your research, think about what makes sense for you and the fact that FREE shipping and well packaged dense foam with handles is something my FedEx driver appreciates and she is a tiny thing.....embarrassing me to no end.....(5 times now). I just ordered the newly released 60A48 charger tonight as well since 500AH is a lot of battery to charge in an emergency and then I can sleep at night when the power is out without listening to a generator or have someone take off with it.
