Are the following MRBF fuses suitable for use with LifePO4 batteries (100Ah 12V):

The datasheet says "The breaking capacity meets the requirements of conventional vehicle batteries and 12V, 24V and 42V electrical networks." which makes me wonder if they are suitable for use with lithium batteries.

When Is A Fuse Not A Fuse ?

Ensure your off-grid power system is properly protected - use the correct fuse. This article discusses the importance of breaking capacity with fuses or MCBs.

LiFePO4 prismatic cell short circuit current and main circuit protection

I am building a LiFePO4 battery bank for my vehicle using 8x EVE 105Ah cells in a 2p4s configuration (12V, 210Ah). While not an EE, I am fairly comfortable with circuit design and protection. My question pertains to main circuit protection, specifically short circuit protection. I see a lot of...

It really depends on the size and voltage of your LiFePo4 bank

It's all about comparing a fuses 'interruption' rating VS your battery's 'short circuit current'

OK, I found another document for the fuses which state the interrupt rating at 14Vdc is 10000 amps, so comparable to a Class T and they should be OK to use with a 12V 100Ah LifePO4 battery

Yes correct , fuse is easily suitable for LiFePo4 100ah@12v
