Pointless being a four-terminal. Two terminals each slot, maybe, but not four. ## Frequently Bought Together - Gloaso 12V-48V Copper Bus Bars 400A Marine Busbar Power Distribution Block Heavy Duty 8X 3/8" (M10) Posts Battery Terminal Buzz Bar DC 400 Amp for Automotive/Trailer/RV/Solar/Boat/Marine | Red&Black - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing - 10pcs 4 Awg - 3/8" (M10) Sanuke Wire Lugs Ring Terminal Connectors Ends, UL Listed Heavy Duty for Battery Cable Lug Wire Electrical Eyelets with 3:1 Dual Wall Adhesive Heat Shrink --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/473050108-copper-bus-bar-12v-400a-heavy-duty-8xm10-stud-battery](https://www.desertcart.pt/products/473050108-copper-bus-bar-12v-400a-heavy-duty-8xm10-stud-battery) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-06*
