### ⭐⭐⭐⭐⭐ Review
*by R***Z on December 16, 2025*

Excelente producto, superó todas mis expectativas. Estoy muy contenta con esta compra maravillosa

### ⭐⭐⭐⭐⭐ Good battery for the price
*by T***Y on November 10, 2025*

I installed these in my trailer about a year ago and they’ve been working perfect. I have a 20 amp electric charger and two solar panels charging the system.

### ⭐⭐⭐⭐⭐ 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!
