Electrical upgrades to 14v

a 300 amp can get very hot as most are designed for a certain RPM range and daily driving can make a it spin very fast and get very hot.
There are good reliable 300A alternators out there, and some are liquid cooled. But they can get very expensive and they are rare. Some may cost in excess of $800 when you can just get a good 200A that will do all that you need it to for $250-$400

i've run a 300 amp for the past 4 years daily with no issues at all.
