## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent
*by I***S on August 5, 2025*

Muy buena, cumple con las expectativas

### ⭐⭐⭐⭐⭐ 300 amps in just slightly over a group 24 size! Wow!
*by K***B on May 20, 2025*

I got this to replace my RV's 100ah 12v lifepo4 so my inverter could run my lights and residential style fridge for roughly 24 hrs. It does the job just fine! It's really light, and the price was great, and takes the space of just under a group 27 battery.I did a capacity test on it, when I first got it, and it came out to 306 ah!The quality seems to be on par with name brand. My only wish would be for slightly longer screws for multiple connections, but the length that comes with it is the same as most of the other manufacturers.Highly recommend this, especially if you are trying to decide whether you should go with the bigger battery. I know now that I should have.Highly recommend!

### ⭐ Bad batch of batteries
*by R***. on June 26, 2025*

Ordered two batteries but they did not work as they should. The first battery was able to wake but when charged to 100% it would immediately drop to 75% when taken off the charger. The second battery would wake after a couple of tries but would not stay awake. Customer service worked with me to try and resolve the problem but was not able to get the batteries going properly.
