US Patent 11916242 Commercial flexible battery pack with secondary output control

A battery pack includes a cell module assembly, a primary power output, and a secondary output connector. The cell module assembly includes several lithium-ion battery cells connected in parallel. The primary power output includes a pair of terminals for connection to equipment to be powered by the battery pack. The secondary output connector includes a secondary power output for connection to equipment to be powered by the battery pack and includes an enable input. The primary power output is configured to supply electrical power at a voltage higher than the secondary power output connector. The secondary power output is controllable through the enable input to selectively supply electrical power from the secondary power output.
