Abstract

A battery pack, as a power source of a cordless electrical tool, is generally the component that functions to limit development of cordless electrical tools. Conventional battery packs usually only have an output voltage under 30V, and upon driving large-power electric tools, they usually cause problems such as insufficient power and undesirable endurance. Currently there is not a battery pack whose output voltage is above 30V and whose structure is safe and reasonable, and a charger adapted for the battery pack. The present disclosure generally describes a battery pack which includes a battery housing, a battery cell assembly, and more than two connection terminals. The battery housing has an insert housing wall. The insert housing wall has an insertion structure having an insertion direction which forms an angle greater than or equal to 0 degree and less than or equal to 45 degrees with respect to a maximum projection surface or a maximum size direction of the battery cell assembly. The battery pack can output voltage exceeds 30V and has a safe and reasonable structure.
