My concern is my ignorance with LFP. Not knowing what I don't know. I know my FF won't last forever I want to make the jump to LFP, just nervous about designing my system myself. Contracting it out will likely be cost prohibitive.
SV/Jedi had a good diagram for an LFP installation a couple months ago in the lithium forum, where the alternator was isolated from the lithium bank. Basically the alternator charged a lead acid battery and the lithium were an isolated house bank. I thought it was a good example of a simple lithium installation/ conversion with the least amount of hassle.

This video mirrors my experience with Firefly G31 batteries. Having said that I do still have one G31 that I am using as an engine start battery...

Re: FireFly Battery Long Term Users - Speakup

If anyone is looking I have three great condition L15+ 4v batteries. Less than 3 years old. 450AH @ 12v nominal capacity. Located in Curacao. I have had zero problems with these since installation. We ran them with 3 other identical batteries.
