Is it safe to use a fuse on a battery?

Probably okay. Consider using a fuse, ideally a fuse right at the terminal or inline as close as possible or a short length of "fusible link". A good practice to get into. Only now, when I've connected it to my circuit, properly this time, the voltage seems to drop rapidly. Like really fast. Could one of the cells be damaged?

What fuses do I need for a lithium ion battery?

With lead acid battery banks, ANL, MRBF, and Class T fuses are all permitted for main battery protection by the ABYC (US marine code), but with lithium's much greater ability to supply current, a fuse with a very high AIC becomes much more useful (or even mandatory--i'm not sure about this).

What is a battery fuses & how does it work?

The standard came into effect in 2012 to reduce the global risk in transporting, storing and operating batteries. The most basic safety device in a battery is a fuse that opens on high current. Some fuses open permanently and render the battery useless; others are more forgiving and reset.

What type of Fuse should a LiFePo battery use?

MRBF and ANL also have moderately high interrupt ratings suitable for a main battery fuse but nowhere near as high as Class T. Class T is also the most expensive. Every engineering paper on LiFePo batteries I have read said use Class-T fuse.

Do parallel batteries have a Class T fuse?

Each one of my parallel batteries has a Class T fuse. The Inverter is preceded with a Class T fuse just in case some MOSFET blows out and creates a short. Yes, expensive, but absolutely worth it - especially with higher voltage systems where ANL is not an alternative at all.

What is a safety device in a battery?

The most basic safety device in a battery is a fuse that opens on high current. Some fuses open permanently and render the battery useless; others are more forgiving and reset. Figure 1 illustrates the top of an 18650 cell for Li-ion with built-in safety features.
