Why upgrade your marine alternator?
For fast and efficient charging, most conventional marine alternators do not manage the constant, high-load output required by lithium batteries and large AGM bank systems. To avoid high charge losses due to heat and hard use, a high-output alternator is recommended. We have multiple options for most applications through the following suppliers:
high output small case marine alternators
custom serpentine pulley kits
- high output large case marine alternators
- 12V, 24V, and 56V systems
- high efficiency, secondary alternators
In order to get the most out of your marine alternator and maximize the life of your batteries, it is important to choose the right alternator regulator for your system. We carry regulators for both lead and lithium systems.
