Is anyone out there running lithium batteries on an FX20/21 or ZX (particularly LithiumPros)? If so, how did you configure? And did the dealer set up or did you add aftermarket?
I'm close to finishing a new boat build and plan to go the lithium route. The key question is the dealer is recommending a second lithium 12V cranking battery just in case. I plan to run a fairly electronics heavy boat but available literature and online research seems to suggest the Lithium Pros M3110 12V 110Ah battery is probably plenty. For obvious reasons, I am reluctant to spend a big chunk of change on a 2nd cranking battery if it will likely never be used...but interested in Skeeter owners opinions re: need for a backup cranking battery.
Thoughts?
