Default Adding a Radar, should I add another battery too?

I'm adding a solid state Raymarine Radar (Quantum).

I currently have a 2 battery setup with an Aux charging lead to the house battery, and was wondering if I should add a 3rd battery?

I would think you are only running your radar when the engines are running, in which case you are running off the alternator. These things only draw a couple of amps. If that amount of additional draw is enough to overload your charging system, you have more important problems to attend to.

I agree that your engines will likely be running most of the time your radar is. For the few times they are not I would think you will have plenty of battery to run the radar until they are started again. These radars don't draw a tremendous amount of amperage so your engines should more than be able to charge the battery faster than what the radar can drain it. Adding another battery is not needed for what your looking to do.
