    Hello,

    I'm new to the forum, I've been snooping on here for awhile now and can usually find answers without needing to post... until now.

    I am working on a charging system for a motorcycle. It currently puts out 14.6 to 14.8 volts to the battery and the current changes as needed to charge the battery. At the most it will provide 18A or so the manual says. My problem is I need to limit it to 14.4V max, so I was shooting for 14V.

    I'm very familiar with voltage regulators such as the 78XX or the 317 and these work great however they won't handle the amperage. Does anyone know of a circuit I could build that would accept the input voltage of 14.6V and provide an output of 14V all the while sustaining 18A which will change randomly?

    As always I appreciate the help.
