While troubleshooting autoplt problem; discovered electrical system low voltage. No output from either alternator. Attempted reset; no change. Battery voltage dropping rapidly. Turned off all electrical except #2 communication radio. Notified ATC of impending radio failure and requested vector to nearest suitable airport. Evb approximately 6 NM. Controller informed us evb using runway 29 and cleared us to it. Received handoff to evb tower but lost all electrical before making contact. Made pass down runway 29 at 1000 ft and circled the airport while performing manual gear extension. Landed runway 29 and turned off runway. We were able to get a handheld radio working for taxi in to FBO. Did not want to continue into and through the busy dab airspace without radio communication. ATC was very helpful and anticipated our needs.
