Big inverter, big battery bank, big current. One loose terminal and you've got a 125-amp arc that no standard fuse box is going to handle. This Jaycar 125A marine rated battery terminal fuse sits right at the battery post, cutting power the second something pulls too much. You swap the fuse, find the fault, back online. No fire drill. No calling the insurer. Rated for M8 systems up to 48VDC, it's the protection layer serious lithium installs need at this current level. Standard size: 27.8mm L x 16.3mm H x 23mm W. Pairs with Jaycar SZ2024 (single) or SZ2026 (dual output) holders. Add to cart and lock down that install
