Battery isolator diodes introduce a voltage drop of about 0.7\u202fV, which means you effectively lose half of the charging performance.

From a safety perspective, a relay is also preferable, since only cables are required between the alternator and the starter battery\u2014meaning there are no additional components that could fail if something goes wrong.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
