    Hi Koenton,
    To charge any battery the charger voltage must be higher than the batteries voltage. In an automobile, for example, the alternator puts out 13.8 to 14.2 volts to the cars battery. Yes you can limit the current and the important part is that the voltage stays higher. Please also keep in mind that when a lead-acid battery is charging it puts out hydrogen gas the same used in the Hindenburg so please make sure you are in a well ventalated area! Best, Ed
