I have this left over from a model kit, in which I excluded the electronic lights.
It's a battery holder which takes 4 C batteries with a black plastic box to contain it.
Would 4 C batteries be too much power or am I safe with this? And what could I expect the life of the RAM to be with this?
As for wiring, I could solder directly, or alternately, I have this from the model kit as well
It's a power jack which the battery pack plug into. I could attach this internally, allowing me to remove the battery pack if necessary but it might be more trouble to install.
