Over 60% of WakeBoat run times are at idle speed. Many high current electrical loads are engaged at idle, including ballast pumps, high-output stereo systems and multiple instrumentation loads. Standard alternators only produce about 30A-40A at idle speed, leaving these loads to be serviced by onboard batteries. Excessive draining causes battery sulfation and reduced lifetimes. Dealers report that AGM batteries which should last 5-7 years on these vessels are being replaced annually. The XT-Series Alternator produces over 100A at idle speed – ample power to service all electrical loads with power left over to top-off house batteries. The XT-Series pays for itself in reduced battery replacement costs in just one year!

These Alternators contain single stage, internal regulators and are not appropriate for use with Balmar’s multi-stage external regulators.
