There are many reasons why lithium battery packs are in a class of their own. Li-ion batteries can be recharged hundreds of times without need for maintenance. They also tend to have a higher energy density and voltage capacity with a lower discharge rate than their competitors. This makes for better power and efficiency, as a single cell has longer charge retention than other battery types. BigBattery offers the best lithium-ion-powered batteries.
