When it comes to battery technology, selecting the right battery charger is crucial. This is especially true for race cars and street machines that use a variety of batteries. To ensure ultimate battery performance and longevity, Voltage Reducers and Step Down Modules are recommended when using a 16 V battery in long races in vehicles with an alternator. Additionally, it is suggested that 12 V components be connected to resistor them using the voltage step-down boxes.
