I have FFs too. They have been great. The restore cycle is a little hard for me. I have a very efficient frig. System,
spectra watermaker,
Opencpn RPI nav system, and LEDs for
lighting. Without turning on the
watermaker, if I turn everything on in the
boat on and run my 12v blender I might use 12 amps. So it takes me like 2 days to pull down the
batteries.
Charging is easy though, combined
solar,
Honda,
engine for the restore cycle,
solar otherwise. I rarely use the
engine for
charging. I have a switch to turn off the
Ample power V3 charging regulator/alternator. I’ll be doing a restore next week.
What I find on a regular basis is that my banks down 25-40 amps in the morning and charged by mid morning by 400w of solar. I love that acceptance rate on FFs.
I have had them a couple years now. I think the most enjoyable part of owning them is not running the engine or
Honda hours and hours equalizing or doing absorption charging like I did with my old flooded
batteries and I never have to add
water either.
Practically
maintenance free.
