RE: Please help with battery selection.
The thing about the triton is it has to be powered by DC. When using it indoors, you will need a good power supply that converts AC to DC. Computer power supplies work great, and you can usually find an old one here or there for very cheap or free. There is an online battery clinic that shows you how to make the power supply work the way you need it to. It is a very easy project. I made one for mine and it works great.
