I hear and read about so many cruisers with defective Firefly batteries. Its also clear that the manufacturer has usually replaced them under warranty after sending the customer through some testing hoops.
I have also heard the stories about previous production problems that are now 'fixed'. What evidence is there of this fix? Is there anyone on this forum that can report an incident-free experience with Firefly batteries for say two years or more? If not then I'd have to suggest that the jury is still out on reliability of Firefly batteries.
it's good that the company has been honouring the warranty, but personally I'd prefer not to interrupt my cruising season trying to manage the logistics of getting specialist batteries replaced.
I'm still considering my battery replacement technology.
