⑴Is it better to use a car battery or an electric car battery for a 12v light box?

A car battery is better.
1. The car battery is a gold diamond battery with good quality; the electric vehicle battery is an ordinary battery with poor quality.
2. The car battery adopts a high battery life and low power consumption mode; the electric vehicle battery adopts a traditional high power consumption and low battery life mode. Taking the above two aspects into consideration, the car battery is better.

⑵How can a 24v battery be used with a 12v light box?

There are two ways to achieve this:
The first is to connect two 12 volt lights in series and connect them to a 24 volt battery;
The second way is to connect a resistor of a certain value in series with a 12-volt light bulb. Then connect it to the 24 volt battery. Let the resistor share the voltage of 12 volts, so that the working voltage of the bulb is 12 volts and can work normally. But this method results in a waste of electric energy. Only half of the electric energy is used to do work and the small light bulb emits light.
