will the main battery keep it alive to prevent it from dying?
i ask because i am in the process of installing a dash cam. if i hook this up to the 12v accessory battery, will the main battery just keep the accessory battery charged up when the engine is off? or will i be in a situation where my 12v accessory battery goes dead and the car doesn't start even though i have plenty of main battery left?
i also have a power magic pro that i can use to stop the dash cam power if the 12v accessory battery goes below 12v but if i don't need to use it, i won't.
