New question for all about LiFePro4 Lithium Batteries

[Maogwaicat]

Hello All;

My two lead acid 8D house batteries are not doing the job anymore and I am now wanting to upgrade to Lithium LiFePro4. I have a couple questions;
1. Has anyone on this site transitioned to these special batteries? I would like to hear about lessons learned!

2. Are there special requirements or unique alternator required to charge these batteries?

I might just replace current batteries with same for now, but the price point for the modern technology seems to be dropping to affordable levels.

Thanks for any responses!

UPDATE: I just found some relevant comments from a few months back that were responses to a previous post I made about my generator being inoperative. I will pay better attention... If there are any other bits of advice on this issue, I am ready to learn. Thanks again...!

Generally Li batteries are not starting batteries, so you would need 2 different systems, one for starting and one for house. Also they don't charge the same. So you would need a DC-DC charger. They do have there advantages and the prices have come down to be a consideration.

Forgive my heresy, but go to Trawler Forum for a boatload of information. You’ll get all kinds of conflicting info that you’ll need to sort through.

For a very good start also check out MarineHowTo. Rod Collins is a priceless resource.

(I’m still a huge fan of AOG. It’s how I got started, practically from scratch lo those many years ago.)
