Re: LiFePO4 Batteries: Discussion Thread for Those Using Them as House Banks

Re: Painting the yacht

I've seen good results on a friend's boat using Quantum. It was easy to work with and a nice finish. I sprayed mine with Quantum and had a favourable result.

Re: Alternator Size with LiFePo4

I've read this thread with interest and, with one season's experience with my 540Ah of LiFePO4, I thought I'd share my experience.

Re: LFP - Decline in charge acceptance rate with battery age

I do have LFP. 540Ah of them. Only a year so far but my friends have many more. I've not heard them talk of degradation of capacity.

Re: What Are Best House Batteries for Cruising Catamaran?

Dave,

Re: Sterling Pro Batt Ultra and LiFePo4

To be honest, the alternators (I have 2 engines) are the least important to me for charging. Should I have to motor, it would be useful to have a regulated, controlled, albeit lower charge rate...
