Universal Heavy-Duty Waterproof, Dust-Proof & Mud-Proof E-Bike Battery Protective Cover Bag (370mm x 90mm x 120mm) – Weather Shield for Hailong, Tiger Shark, Dolphin, Polly & Jumbo Shark Battery Packs

Shield your high-capacity e-bike lithium battery against driving rain, high-velocity tire spray, abrasive road dust, and caked-on trail mud. While standard downtube battery enclosures offer basic splash resistance, prolonged exposure to heavy downpours or wet off-road trails can force moisture into key slots, power rails, and charging ports—leading to terminal corrosion or dangerous short circuits.

Specifically engineered to fit popular Hailong, Tiger Shark, Dolphin, Polly, and Jumbo Shark downtube battery profiles up to 370mm x 90mm x 120mm, this heavy-duty protective sleeve creates a sealed, weather-resistant outer layer around your battery housing. Featuring reinforced ballistic stitching and an adjustable elastic cinch border, it locks down tightly around your pack to keep your electrical contacts dry and clean in all riding conditions.

🚀 Key High-Performance Features

• Universal Fit for 370 x 90 x 120mm Batteries: Precision-sized to wrap popular downtube battery cases including Hailong 1, Hailong 2, Tiger Shark, Dolphin, Polly, and Jumbo Shark styles.

• Heavy-Duty Weather Protection: Constructed with a rugged, wear-resistant outer shell and a sealed waterproof inner liner that repels heavy rain, sleet, road grime, and salt spray.

• Anti-Mud & Anti-Scratch Shield: Keeps mud, sand, and fine trail dust from caking around the key lock mechanism, power switch, and LED fuel gauge, preserving your battery casing's finish.

• Adjustable Elastic Cinch Border: Integrated high-elasticity border with an ergonomic grip pull tab allows for fast installation, secure hold at speed, and easy removal for charging.

• Easy Wash & Fast Drying: Road mud and dust wipe off easily with a damp cloth, or you can slip the cover off for a quick cold-water rinse after heavy trail rides.
