A modular electronic system is provided wherein a first device is powerable by a first rechargeable battery. A connector operationally connects the first device to a second device powerable by a second rechargeable battery. A charge control circuit is included in the first device for determining the condition of charge of the first rechargeable battery and determining the condition of charge of the second rechargeable battery. The charge control circuit includes means for charging the battery with the lower condition of charge from the battery with the higher condition of charge. In this way, by sharing power resources, the cooperative operational life of the devices can be increased. |
