you can easely make the calculation yourself...... take the worst case and count all the amps you need from the "users"... don't count on any "reserve" from the batterie.... once in the "-" ,time go's fast...ourselfs ever had to abandon the Rally Ypres Belgium in the dark because of a mal functioning alternator... we had no fuel pressure anymore because of the headlights... and ofcourse some reserve is always welcome .... radio ???
