Fuses and fuse holders

MIDI, MEGA, MRBF and Class T fuses with the holders to match. Every unfused battery cable is a fire waiting for a chafe point, so fuse the positive as close to the battery as you can physically get it.

Class T is the one to use on a lithium bank. It has the interrupt capacity to clear a dead short from a battery that can deliver several thousand amps, which a MEGA fuse cannot. MRBF mounts straight onto the battery post, which removes the run of unprotected cable that most installations leave between the battery and the fuse.

Check the holder's cable range before you order: the fuse rating and the cable it clamps are two different limits.
