Ladies and/or Gentlemen,
I've recently acquired a set of Promark 3 receivers and was curious about using an external battery to power one of the receivers as a base. My question is this : can I power the promark 3 with a 12 volt battery, such as a motorcycle battery, without having to have any kind of inline reduction in voltage? In other words, will using an external battery straight to the receiver harm the receiver?
I use the Magellan cigarette lighter power adapter 730394-01-E and a portable starter pack.
Mine cost $18ea and they are like $70+ online if you can find one.
You can use a 12v DC source because that is what the office charger outputs.
A car battery outputs nearly 14v when fully charged and that may be too much.
I like using the adapter because it regulates power and provides a fuseable link in case of a surge.
Before I got the adapter I used a car battery connected to a 120v inverter connected to the office charger.
Thank you, Mr. Harris.
