An energy system includes an energy storage device and a link device. The energy storage device includes a housing and a battery disposed within the housing. The battery has a first chemistry. The link device is configured to facilitate electrically coupling the energy storage device to an external battery having a second chemistry different than the first chemistry, receive input power from the external battery, and regulate a power profile of the input power received from the external battery such that the energy storage device can accept the input power from the external battery. The energy storage device is configured to receive the input power from the external battery having the second chemistry through the link device and provide output power to a load using the input power received from the external battery having the second chemistry.
