Any two years reviews for Firefly batteries?

[donradcliffe]

The good news is the Firefly technology works, but bad news is they have been having quality control problems since they shifted their manufacturing location. Am I right??

So long as your purchase in the US was through the official dealer network that Bruce @Ocean Planet established, you should have be secure in their warranty handling

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.
