I bought this because my lithium battery was not charging to 100%. They recommended I used their charger because their charger can help diagnose if the battery is good or not. Unfortunately my battery went bad but since it was still under warranty and I met the warranty requirements they sent me a new battery. I will be using their charger with their battery from now on. I have been happy with their products and their customer service was great. They did not wait long to send me the new battery which was amazing!

Updating my comments and adding the picture of my rack. Getting ready to expand with their new V3 battery. I love the way they listen to users and making improvements on their products. Hopefully they will sell the individual Solar panels they have on their off grid kits separately.

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.
