Well all my house batteries have been removed, sizzling, so new batteries need adapters to hook up. The adapters may be a while, question, is it safe to have shore line power hooked up with no batteries? At least until we get the adapters.
Don't know about anyone else but you lost me at needing adapters to hook up batteries!!!!!. It had batteries that were connected? What would be different about new batteries that couldn't be put back the same way?

The previous batteries had standard terminal post and smaller wire post. When I got the new batteries they had the terminal post only. It didn't dawn on me when I got home it needed the smaller post for the connectors.
If it is a OEM converter, the DC off of it could be "rough" and possibly damage LEDs or electronics. If you can connect just one battery utilizing small C-clamps or large clips (like a battery booster clamp) just to make a decent connection and ensuring you do not draw too much power. Just be careful working with the battery.
If you have a quality Inverter c/w charger, you may be able to run w/o a battery.
