Customer Reviews
Hello Kevin, The battery pack is working extremly well and I'm pleasantly surprised by the power it supplies. I will buy more in the future.

—— Mr Daniel (USA)

About the order, I am very satisfied about quality (180AH Lifepo4) cells are very good! I used them into my new project for electro solar catamaran I made myself 2014/2015. It is very nice...very good! My Best
