1. A gas engine replacement device, comprising:
a housing;
a battery receptacle coupled to the housing and configured to removably connect to a battery pack including a first electronic processor and a memory storing battery pack configuration data;
a motor located within the housing;
a power take-off shaft receiving torque from the motor and protruding from a side of the housing;
a power switching network configured to selectively provide power from the battery pack to the motor; and
a second electronic processor connected to the power switching network and configured to control the power switching network to rotate the motor,
wherein at least one of the first and second electronic processors is configured to detect a connection of the battery pack to the battery receptacle and the first electronic processor is configured to revise the battery pack configuration data stored in the memory in response to detecting a condition and communicate the revised battery pack configuration data to the second electronic processor, and
wherein the second electronic processor is configured to control the motor based on the revised battery pack configuration data.
