First post here. I've lurked for a while but recently read about class T fuses and lifepo4 batteries and needed some help. Below is a diagram of my set up. I have a 100ah renogy lifepo4 battery that I use to supplement my goal zero yeti.

I charge my goal zero yeti from my lifepo4 battery using their 5A and 10A car charger in the 12v female cig outlet. The other two connections are for charging the renogy lifepo4 battery from solar or from shore power. This is all enclosed within a NOCO battery box.

This set up has worked great for me, but I'm wondering if there's a better way to set it up. Do I need a class T fuse from the battery? Is a MRBF fuse or my existing set up sufficient? If I'm draining the lifepo4 and charging it, the max amps would be 30A (10A discharge + 10A shore OR 10A discharge + 20A solar).

Thoughts?
