A rechargeable energy storage system may include a series arrangement of a plurality of batteries coupled to a first DC bus at a first DC voltage. A DC to DC converter may include a multi-input DC input stage coupled to a multi-output DC output stage. The multi-input DC input stage may include multiple distributed DC inputs, each distributed DC input being coupled to a respective one of the plurality of batteries. The multi-output DC output stage may include multiple aggregated DC outputs. At least one controllable switch may couple one or more of the multiple aggregated DC outputs to one or more other DC buses.
