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
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.
