Abstract
A battery pack is provided that can better manage peak current of in a converged portable radio. The battery pack comprises an internal Li-Ion cell stack characterized by a linear output voltage curve. A DC-DC converter converts the internal cell stack voltage to a desired DC-DC converter output voltage. The output voltage and current sourcing capability of the battery pack remain constant over the full cell discharge curve. The battery pack optimizes cell utilization, without the use of any internal microprocessor, thereby supporting the operation of simultaneous high peak current application features associated with LMR and LTE.
