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.

An electrical apparatus includes first and second battery interfaces disposed on a housing for electrically and mechanically connecting first and second battery packs in series. A controller is disposed within the housing and includes an apparatus microprocessor that receives first and second communication signals respectively outputted from respective microprocessors of the first and second battery packs. A first signal communication path communicates the first communication signal from the first battery pack microprocessor to the apparatus microprocessor by shifting a first voltage range of the first communication signal to a second voltage range that is suitable for inputting into the apparatus microprocessor. A second signal communication path communicates a third communication signal from the apparatus microprocessor to the first battery pack microprocessor by shifting the second voltage range of the third communication signal to a first voltage range that is suitable for inputting into the first battery pack microprocessor.

An electronic torque wrench with a battery receptacle adapted to receive either a unitary battery pack or a battery tray containing separate batteries inside. The battery tray can receive conventional batteries such as AA, AAA, C, D or 9-volt sized batteries, and the battery tray and unitary battery can be constructed of a similar geometry to fit within the battery receptacle. The battery tray and unitary pack can include an outwardly-extending protrusion that is received within a groove of the battery receptacle. In this manner, only the specially-designed battery tray and pack are capable of coupling with the receptacle.
