Fuses and holders for battery and DC work: MINI blade fuses 2A-30A at 58Vdc, MIDI 30A-200A at 58Vdc, Cubic battery-post fuses 50A-300A, an Eaton MEGA 80A-350A at 125Vdc, and the matching holders — MINI blade, MIDI 200A and Cubic 300A.
Read the voltage before the amperage. The MINI and MIDI bodies are rated 58Vdc, which covers 12V, 24V and 48V banks but nothing above; the MEGA at 125Vdc is the part for higher DC voltages. A fuse chosen on current alone can be the wrong body entirely.
Holders are sold separately, and the Cubic type bolts straight to the battery post, which keeps the protection as close to the source as it can get.
