12V 330AH Lifepo4 Battery, Big Capacity Lithium RV Battery With Bluetooth and 200A BMS,Up to 8000 Deep Cycle.Perfect for RV,Solar Energy,Off-Grid System

330AH battery arrived with 53% charge and then charge fully without issue. The battery is heavy but very light based on the AH available. I used a 20 amp charger and had no issue charging the battery. The cells are within .001 and .002 v which is great so no balance issues which is important for cell life. I’m very happy with the battery, price, and delivery. Bluetooth was important for me since I have 3 other batteries that use the same app. The app works great and connect no problem.

Excellent mini battery.I used two of these in a portable solar generator. They were much lighter than standard batteries and smaller than the usual Lithium. Because of their size, I was able to use two, instead of the normal one in this project. They charge fast and I was able to get them balanced with no issue by charging one completely then the other before hooking them up.

Product arrived on time and was easy to install to my 24v trolling motor. It is so much lighter than my two12 volt led acid batteries I had previously. This battery lasted two full days of fishing before it needed a charge. I bought a 40 amp lithium ion charger and it charged up very fast. This battery functions well and is high quality with great design.

I have the battery installed in my van to run a 12v AC unit (10K btu).Weight and size worked out great. Power can run the AC for a little over 5hrs on turbo setting.Once it gets to temp, you can almost get 8hrs of run time.The rope handles on the battery are a bit silly.The protrusions that are the handles should be removable.Update: Had some issues that I mentioned to the company and they responded kindly.Provided additional information, specs, and instructions on BT app, since its in Chinese.Hint: you can take a screen shot of what you cant read in instructions, and slip it into ChatGPT to translate it.Buy 2 and you get 660ah for less than a 600ah. Plus they're smaller and stackable compared to the size of a 600ah.

Great 330Ah battery for the price! This almost doubled the Ah capacity of my previous 2-battery set up. It fits perfectly in the stairwell of my 2023 Forest River Forester 2441DS Classic; no cutting needed! For its size, I might be able to add another one in the same compartment!This larger 330Ah was in same price point of other LiFePO4 batteries with only 300Ah the time I was shopping.The app works flawlessly and has good BT range.

Gave one star only cause I had to. Don’t order these. To pay over 300 bucks and the batteries be dead after a short period of time is a waste. I have these hooked to a solar system. They done great at first. Then they got tested out good once. And ever since then they’ve been dying and no my whole solar system is down. My charge controller won’t even come back on!!! The app to monitor the batteries is trash and does you no good. My experience is so bad with this system I’m ready to say screw living in America and just leave the damn country where I can afford real electricity. The money I used to pay for these batteries should have been used to buy a plane ticket. Stay away from these batteries. They lock down after discharged and you can’t do anything with them afterwards unless you have a way to charge each battery one by one.

The battery arrived with a proper charge and in good shape. The case seems quite sturdy and the terminals feel very secure. This is a whole lot of battery for the money. It's installed now and working as intended. I couldn't get the Elefast app to download so I used the overkill solar app and it works fine with the BMS. I don't think you could buy cells, case and BMS for this price. I hooked it to a 2500 watt inverter and ran it to its capacity with resistive loads and the battery performed as it should. I couldn’t be happier with it.

⭐⭐⭐⭐⭐Absolutely impressed with the Elefast LiFePO4 battery! From the moment I unboxed it, I could tell this is a high-quality, well-built power source. The sturdy design, clear terminals, and convenient carrying handle make it super user-friendly. Performance-wise, it delivers reliable, long-lasting power — perfect for my energy needs. The battery holds charge exceptionally well and charges efficiently too. If you’re looking for durability, performance, and peace of mind, Elefast is the brand to trust. Highly recommended!
