OptiMate O-31s x20 Slim SAE Heavy Duty Weatherproof Premium Battery Lead Bulk Pack (20-Count) with M6 Ringlets for Powersport Batteries

The OptiMate O-31s x20 is a professional bulk-pack containing 20 of our specialized, weatherproof premium battery leads featuring a ultra-low-profile, slim SAE connection system. Engineered specifically to accommodate the tight clearances on modern powersport vehicles, each lead bolts securely to standard M6 motorcycle, ATV, or side-by-side battery terminals to create permanent, quick-connect charge access for your 12V lead-acid or 12.8V/13.2V lithium (LiFePO4) batteries.

Features and Benefits

• Professional 20-piece bulk pack — Designed for motorcycle dealerships, commercial repair shops, fleet operations, or battery distribution specialists looking to outfit multiple units efficiently.

• Ultra-low-profile slim SAE connector — Measures just 16 mm (21/32″) x 8 mm (11/32″), allowing a clean, non-obtrusive fit inside the tightest battery compartments or body panel gaps where standard SAE plugs won't fit.

• Sized for powersport batteries — Heavy-duty ring terminals are perfectly sized to fit standard 1/4" (M6) bolts found on powersport battery configurations.

• Universal chemistry compatibility — Designed to optimize connection reliability for both traditional 12V lead-acid (STD, AGM, GEL) and modern 12.8V / 13.2V Lithium LiFePO4 / LFP battery types.

• Length: 50 cm (20″) cable delivers the ideal routing length to bring the charging port out from under the seat or behind the fairing to an accessible frame location.

• 18 AWG / 0.82 mm² cable — Features high-purity copper strands wrapped in rugged SPT-2W insulation to maximize voltage sensing accuracy and provide heavy-duty abrasion resistance.

• Targeted inline safety protection — Each harness is equipped with an integrated 7.5A mini ATO fuse to shield the vehicle's electrical system, battery charger, and wiring from short circuits.

• Dual-color weatherproof protection — Includes matching slide-on rubber sealing caps in both black (for standard setups) and green (for easy visual identification of a lithium-equipped vehicle) to lock out moisture, dust, and grime.

• Rated for –40 °C/°F — Built to survive extreme conditions; premium weatherproofing ensures the insulation stays completely pliable and crack-resistant even in severe sub-zero winter temperatures.
