Automatic Car Start Battery Charger

Car: 1999 Saturn SL2 Silver,... do I need to say more?

Was wondering if anyone knew of a device that you install in your car to monitor battery levels. In my case, I'm a HAM radio operator:thumbs: and I sometimes need to leave my radios and or lights on when the car is off.

When the battery reaches a critical level, it can start the car and let the battery charge and then shut the car off again.

My thoughts are buying a Hellroaring battery isolator/coupling kit and just installing a second battery in the trunk.

Your thoughts would be greatly appreciated.

Thanks,
