Abstract
A battery pack having at least one battery cell and an electronic circuit for controlling the charging and discharging of the cell(s) includes an enclosing cover and base which define a cavity and a partition which extends across the cavity to define separate portions for the electronic circuit and the cell(s) respectively. Preferably the cover and base are attached at their edges and the partition is formed of walls in each which interleave when they are brought together. A flexible material such as silicone rubber fills any void between the partition walls to isolate the electronics cavity from the battery cell cavity and provide a gas-proof seal.
