What are the differences between Magnum batteries?

Batteries are classified by voltage and amp hour. The voltage can be thought of as the size of an engine, this determines the power output. A 48V will be more powerful than a 36V.

The amp hour can be thought of as the size of a gas tank. The higher the number, the greater the range. A 17.5ah has a longer mile range than a 13ah battery.

*Safety note: Battery voltage should be compatible with the controller and charger you are using. For example, only use a 48V charger with a 48V battery. Using an incompatible charger or controller could damage your battery, bike, or even cause an electrical fire.
