A rechargeable electrochemical cell pack is provided having a casing holding a plurality of electrically interconnected cells and having circuit breaking means to guard against the possibility of excessive supply and consumption of electrical power and the risk of damage or injury incident thereto.

A rechargeable electrochemical cell pack is provided having a casing holding a plurality of electrically interconnected cells and having circuit breaking means to guard against the possibility of excessive supply and consumption of electrical power and the risk of damage or injury incident thereto. The circuit breaker comprises a small current fuse contained internally of the cell pack so as to give an external visible indication of its state and is removably mounted on an access door for replacement purposes.
