Can the electric car be replaced with a large battery?

1. The nominal voltage of the battery must be the same as that of the original car battery. For example, the original car battery voltage is 12V, and the replacement battery must also be 12V, which cannot be high or low. Otherwise, the bicycle cannot be used normally and the related parts may even be damaged.

2. The capacity of the battery is large, and the volume is also increased. The bicycle may not fit in the place where the battery was originally placed. You can deal with it this way, buy another battery that is the same as the original car, connect the two batteries in parallel, and find another place for the new battery.

3. To understand some basic knowledge of electricity, for example, connecting batteries in parallel is to connect their positive electrode to the positive electrode, and the negative electrode to the negative electrode. They cannot be reversed. Again, the voltage of the two batteries must be the same.
