A modular battery system provides propulsive power to the rotor system of an aircraft. The modular battery system includes an array of battery modules arranged in at least one stack. Each battery module includes a plurality of battery cells, a first side having positive and negative receptacles and a second side, that is opposite of the first side, having positive and negative plugs. The receptacles and plugs are configured such that adjacent battery modules in a side-by-side relationship are electrically coupled together via plug and receptacle connections and such that the battery modules are electrically coupled together in parallel. An interconnection electrically couples each stack of battery modules together via plug and receptacle connections with one of the battery modules in each stack such that the stacks of battery modules are electrically coupled together in parallel.

A system for picking items from a containerised storage system is described. The items are stored in storage bins in stacks within a framework comprising a grid system disposed above the stacks of bins. Robotic devices are disposed on the grid, the devices acting so as to pick containers from the stacks of bins. The storage system is provided with at least one picking device for picking items from bins and depositing them directly in delivery containers DT.

A battery pack includes a housing, a positive terminal and a negative terminal, and a plurality of cell module assemblies. The positive terminal and negative terminal are each externally accessible from the housing and extend into a first compartment of the housing. The cell module assemblies are received in a second compartment of the housing, and are coupled to the positive terminal and the negative terminal through a connection extending from the second compartment into the first compartment. The first compartment is accessible through a first panel that is movably coupled to the housing through a first securing mechanism providing a first level of access. The second compartment is accessible through a second panel that is movably coupled to the housing through a second securing mechanism providing a second level of access.
