[QUOTE="Roland, post: 8198897, member: 647142"] If you want your battery to last try to keep your voltage above 13.5. The higher you keep your voltage the longer your battery will last. I have 3000 watts of amps in my van with it 130 amp stock alt and it rarely drops below 14.2 volts. I have a 80 amp (=1136 watts) inline fuse going to all three amps so it CAN'T pull to many amps. Most people run their systems only pulling just fraction of rated power... I think you should be good a 145 amps [/QUOTE]
