## Customer Reviews

### ⭐⭐⭐⭐⭐ Great size, power and capacity for the price
*by P***G on July 17, 2025*

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.

### ⭐⭐⭐⭐⭐ Great battery long lasting
*by A***A on July 22, 2025*

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.

### ⭐⭐⭐⭐⭐ Powers a 12v AC unit, BT is Chinese, Battery is strong, solid, good performance & purchase
*by M***K on July 20, 2025*

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.
