When selecting a battery for a vehicle-mounted crane, it is crucial to consider two key performance indicators: voltage and battery type. An important point to note is that the voltage of the new battery must match the rated voltage of your electric winch. Commonly, it is 12V or 24V. Typically, 12V is paired with one battery, while 24V is achieved by connecting two batteries in series or using a dedicated 24V integrated battery. The load capacity of vehicle-mounted cranes ranges from 500 kg to 2 tons. Always leave some safety margin when making a selection.
