Universal Waterproof & Dust-Proof Anti-Mud E-Bike Battery Cover Bag – Heavy-Duty Weather Protection Sleeve for Hailong, Polly DP-5/6/9 & Tiger Shark Downtube Lithium Batteries

Keep your high-capacity e-bike lithium battery completely shielded from heavy rain, trail mud, winter road salt, and abrasive road dust. The Universal Waterproof & Dustproof E-Bike Battery Cover Bag is an essential protective accessory designed specifically for popular Hailong, Polly (DP-5, DP-6, DP-9), Tiger Shark, and Dolphin downtube battery cases. Constructed from heavy-duty 1680D Oxford cloth with a thick waterproof internal coating, this wrap-around sleeve prevents water intrusion through keyholes, discharge ports, and baseplate rails.

Whether you're tackling wet off-road trails, commuting through daily downpours, or keeping your e-bike locked outside, this protective sleeve extends your battery casing's service life, prevents electrical short circuits, and keeps your pack clean for indoor charging.

🚀 Key High-Performance Features

• Universal Downtube Battery Compatibility: Engineered with an adjustable elastic drawstring and dual cinch buckles to fit standard Hailong (HL1, HL2, MAX), Polly/Jumbo (DP-5, DP-6, DP-9), and Tiger Shark battery enclosures.

• 1680D Waterproof Oxford Fabric: Made from rugged, tear-resistant 1680D Oxford cloth that sheds water instantly, blocking rain, road spray, and wet slush from reaching sensitive electrical contacts.

• Complete Mud & Dust Shield: Sealing tightly around the battery housing, it prevents fine grit, sand, and mud from caking into the power switch, LED fuel gauge, and key lock.

• Quick Drawstring Cinch & Release: Features high-elasticity cinch cords with locking buckles on both sides for a snug, aerodynamic fit that eliminates flapping at high speeds.

• Easy Wash & Fast Drying: Easily wipes clean with a damp cloth, or rinse off after messy off-road trail rides.
