1. An energy storage module for a generator start system, the energy storage module comprising:
one or more ultracapacitors;
a two-post electrical connection comprising a positive terminal and a negative terminal,
wherein each of the positive terminal and the negative terminal is electrically connected to the one or more ultracapacitors for charging and discharging the one or more ultracapacitors;
an electrical circuit interfacing with the one or more ultracapacitors; and
a plurality of Positive Temperature Coefficient (PTC) thermistors disposed in parallel within the electrical circuit for passively limiting a charge current of the one or more ultracapacitors based on an internal temperature of the energy storage module and passively distributing the charge current within the electrical circuit.
