High-Output Marine Alternators and Regulators

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:
