Space Engineers – Are There Other Blocks That Don’t Return All Components Like the Battery?

Keep in mind that in order to charge a battery you need a power source (duh!). You can charge a battery with solar panels, nuclear reactors or another ship/station.

You need to have your working power source on the same grid as your battery or have your ship docked to a grid with a power source. You can dock using a merge block or any other blocks that allows you to transfer ressources.

You could have a station with multiple reactors/solar panels and multiple docking ports. This would allow you to have your own recharge relay so you can charge your small ships there.

As you already know, a battery is used to store power, any kind of power. If you can generate power, you can store that power in a battery as long as the power can get to a battery. They get power the same way other blocks get power. Must be on the same grid and turned on.

This seems to be a bug in the current build. If one wants to work around it, set the owner to yourself and share the assemblers with everyone. This makes them work in coop mode again. Another solution is to build them in a way that does not require the use of any conveyors, including the connection to any sort of container.
