Quick Description:Adapter allows the user to power radio from external source and switches over to battery power when external power falls below 11V.

This adapter fits between the battery and radio. It allows the radio to be powered from an external power supply while keeping the battery isolated. Once the external power drops below 11V,  the battery is then engaged and the external power is disengaged. The switchover occurs in milliseconds and does not interrupt the radios ability to function normally.  

Conversely, once external power is restored, the battery is once again disengaged.
