*High Performance batteries: Watt hours calculated at 11.1V. When comparing solar generators like this, make sure you are comparing watt hours at the nominal voltage (around 12V, in this case 11.1V). Some manufacturers use the CELL voltage (Typ. 3.7V) to obtain fictionally higher watt hours.
Compared with traditional batteries, Cutting Edge Power lithium ion batteries charge faster, last longer, have a higher power density (more battery life) and are lighter. They have proven to be superior against lead acid, NiCd, AND lithium Iron Phosphate (LiFePO4) batteries for wind and solar applications. Safe. Compatible. Powerful.
