1. A method of charging and distributing power between a plurality of rechargeable batteries, the method comprising:
providing a battery charging circuit configured to supply a charging current at a first time to a first rechargeable battery of the plurality of rechargeable batteries, and to provide the charging current at a second time to a second rechargeable battery of the plurality of rechargeable batteries;
supplying the charging current at the first time to the first rechargeable battery of the plurality of rechargeable batteries;
switching, at the second time, the battery charging circuit to supply the charging current to the second rechargeable battery of the plurality of rechargeable batteries;
providing a battery power supplying circuit configured
to receive a stored rechargeable battery power from at least one of the plurality of rechargeable batteries, and
to deliver the stored rechargeable battery power to an electrical load; and switching between one of
supplying the charging current to one of the first rechargeable battery or the second rechargeable battery of the plurality of rechargeable batteries, and
receiving the stored battery power from the one of the first rechargeable battery or the second rechargeable battery of the plurality of rechargeable batteries to enable delivery of the received stored battery power to the electrical load.
