Put simply, our custom batteries are simply the best available, quality checked for performance, and made with the highest quality Japanese hardware, using only Sanyo/Samsung Lithium Ion cells. The result is reliable batteries that deliver the power you need, adjustable as you need, all while meeting industry quality certification standards.

We've bought and tested batteries from every conceivable source. There are far too many junk batteries on the market. Don't be fooled by similar designs using unbranded, mix-matched hardware/software and unreliable cells from China. They are not the same as what we make, often defective, and tend to even fail to deliver on the specs they claim. 6 temperature settings (100%, 90%, 80%, 65%, 50%, 25%)
